FIELD
[0002]
The present disclosure relates to wireless communication technology, and more particularly, to a wireless communication system, in particular apparatus and method for secondary access authorization (Licensed Assisted Access, LAA) system and a wireless communication system which enables a wireless communication system information exchange between different operators and equipment to address the issue of coordination between different operators unauthorized devices on the band.
Background technique
[0003]
The future of wireless networking equipment to deploy more intensive, there may be a different physical layer technologies using multiple carriers in a limited geographic area. Different from the conventional LTE system, LAA frame may be wider transmission bandwidth. In an unlicensed frequency band, different operators may compete for the same channel, resulting in data transmission conflict is inevitable. Location different cells overlap each other can be done if recognized, may be used to improve collision avoidance mechanism corresponding channel utilization. Wi-Fi system uses overlapping basic service set identification achieve different colored set of services, conventional LTE carriers later different frequency bands for data transmission, and therefore problems of different operators compete for the same channel does not exist.
[0004]
Inter-operator coordination of programs proposed by the existing literature is mainly used unlicensed band spectrum sharing. In a conventional spectrum allocation scheme, a single operator exclusive spectrum, spectrum utilization rate. To solve this problem, the existing literature suggests that shared main channel program, namely multiple operators together to buy the same channel using the same channel and coordinate resources. Different operators may use different physical layer technologies, resulting in inter-carrier difficult to decode, so the current inter-operator coordination program primarily from frequency selection and power control two aspects. Conventional inter-operator coordination scheme or a frequency spectrum into a plurality of small pieces of equipment of different operators dynamic frequency selection; pool or build frequency, different channel selection algorithm to ensure that a minimum frequency of collisions may choose different operators; or by way power control to minimize conflicts between equipment operators. However, for most of the current operator, licensed spectrum purchase has been completed, and the use of unlicensed frequency band subject to many limitations, and therefore can not be directly between the above operators licensed bands coordinated program for the unlicensed frequency band.
[0005]
For coordination between operators unlicensed frequency bands, we first need to solve the identification problem of different operators. Public land mobile network identity LTE system (Public Land Mobile Network ID, PLMN ID) can be used to identify different operators. A plurality of standardized QUALCOMM Proposal (Qualcomm Incorporated) proposed proposed using channel state information reference signal (Channel State Information-Reference Signal, CSI-RS) and other reference signal carries PLMN ID, used to identify the different carriers, and may be further for interaction between operators. However, the literature has also referred to the same reference signal can not carry a plurality of PLMN ID; existing standards for the reference signal, the reference cells of different operators of the same signal formats may cause identify conflicts; and synchronization, since the alignment between the different carriers, etc. issues that may need to be repeated to send PLMN ID, in order to achieve inter-operator mutual recognition. Further, PLMN ID information carried is limited, the transmission process in case of interference may not be demodulated correctly, and therefore may not be used on unlicensed bands between carrier coordination.

Detailed ways
[0051]
The exemplary embodiments of the present disclosure will be described below in conjunction with the accompanying drawings. For clarity and conciseness, in the specification are not all features of an actual implementation. However, it should be understood that many decisions must be made to the specific embodiments of the development of any such actual embodiment of the process in order to achieve the developer's specific goals, such as compliance with those restrictions related systems and services, and these restrictions may be subject to change with different embodiments. In addition, it should be understood that, although the development work can be very complex and time-consuming, but the benefit of this disclosure to those skilled in the, this development is only a routine task.
[0052]
Here, also be noted that, in order to avoid unnecessarily obscure the details of the present disclosure, the drawings only shows a program according to the present disclosure closely related device structures, and / or processing steps, omitted additional details of this little public relations.
[0053]
Next, an embodiment of the present disclosure will be described with reference to FIG. 21. 1 to FIG.
[0054]
First, a functional configuration example of FIG transmitting side radio communication system according to an embodiment of the disclosed apparatus will be described. FIG. 1 is a block diagram illustrating a functional configuration example of the transmitting side radio communication system according to an embodiment of the disclosed apparatus.
[0055]
1, the apparatus 100 according to this embodiment may include a channel detecting unit 102 and the coordinating unit 104.
[0056]
Channel detecting unit 102 may be configured to detect whether an unauthorized transmission of the channel in the band idle. Before Specifically, in order to avoid interference on the same frequency band existing links in the unlicensed band transmission signal, the device must first listen to ensure that the signal is transmitted only in the case where the channel is idle, the process may be referred to listen after saying (Listen-Before-Talk, LBT). Channel detecting unit 102 may detect whether the channel is idle transmitting end by any means known in the art, the most simple manner the energy detection. If energy is detected on the current channel exceeds a predetermined threshold energy value (e.g., clear channel assessment (Clear Channel Assessment, CCA) threshold), that the current channel is busy, or that the current channel is idle. As an example, assume CCA threshold is -62dBm, if the detected value of the transmission power higher than -62dBm side channel, the transmission of the channel is considered currently busy, or that the transmission of the channel is idle.
[0057]
It should be noted that, although the example is described in any other way by an energy detection method for detecting an unauthorized channel is idle on the band, but the present disclosure is not limited thereto, but is also well-known in the art to detect whether the channel is idle.
[0058]
Coordination unit 104 may be configured in a case where the transmission of the channel is idle, the transmitting side so that the coordination between operators broadcast signals before transmitting data stream, for effecting information exchange between different operators devices.
[0059]
Here coordination between operators is the use of the signal energy on the presence or absence of the specified band to achieve temporal information exchange between different operators apparatus - energy pattern plane signal in the frequency domain, and may be referred to as IOC signal. Specifically, as described above, the easiest way to detect channel energy detection, so if the energy on the presence or absence of a particular subcarrier designed pattern, a pattern can use this energy to carry information related to the link, to receive the inter-carrier vendor coordinating signals may be determined that the link information carried by the signal energy detection mode, in order to achieve the information exchange between different operators devices, in order to achieve coordination between the operator devices.
[0060]
Made according to the invention is based on the design. By energy pattern signal is encoded, i.e., by setting the energy and duration of the presence or absence of the band, in the time domain may be - may be formed in the frequency domain conversion pattern, different patterns may correspond to different link information. Thus, instead of the prior art communication parties need to know both the code modulation and coding scheme and demodulates the electromagnetic signals of the present and accordingly to achieve information interaction, coordination signal in accordance with the present disclosure between operators, only by detecting energy on the respective subcarriers the coordination of information between operators signal carried can be easily determined, so as to easily implement information exchange between operators.
[0061]
FIG 2 is a schematic diagram illustrating a pattern according to the instructions represented by signal coordination between operators embodiments of the present disclosure.
[0062]
2, the horizontal axis represents time and the vertical axis represents the subcarrier number, and in this example, may be considered in accordance with the high and low frequency sub-carriers are arranged, i.e., subcarrier number represented from low to high from low center frequencies of subcarriers to high. In FIG. 2, each square represents a pattern unit in the frequency domain may be one or more subcarriers width, and in the time domain may be an actual physical device and may transmit a detected or more of the minimum unit of time. In Figure 2, hatched boxes indicate these sub on a carrier of energy, i.e., a signal is transmitted on subcarriers, while empty boxes indicate no energy on these subcarriers, i.e., no signal is transmitted on subcarriers this also applies to the other drawings.
[0063]
Specifically, in the example shown in FIG. 2, the first portion of each interval a certain number of sub-carriers, there is a small number of subcarriers or the transmission power, the transmission power long duration, exhibits a stripe pattern; first portion and a second portion Similarly, the fringe spacing and unequal stripe width; the third part, in a first period, a set of subcarriers at intervals of a set of energy transmission, energy transmission subcarrier spacing and a second subcarrier position exchange period, presenting checkerboard pattern; the fourth section, when the sub-carrier transmission range in length, decreasing after the first increment, presenting a symmetrical sawtooth shape.
[0064]
As can be seen, by setting the energy of the band on the presence or absence of energy duration, the time domain may be formed - energy pattern signal in the frequency domain, and a different signal may correspond to a different energy pattern signal content, which can use energy pattern signal to achieve information transfer for the purpose of interaction.
[0065]
Preferably, the inter-operator coordination signal may include a flag pattern and the link information in at least one pattern, wherein the marker pattern is a periodically repeating pattern of the energy-carrying energy of a predetermined subcarrier position, and the link information is carried in the pattern of energy subcarrier location and duration may encode variable energy pattern.
[0066]
Repeating pattern in the frequency domain, i.e., certain rules specified location agreed position as the subcarrier, the transmission signal energy in these conventions position and a predetermined time duration, the time domain to form a - specifically, for the marker pattern, the time domain may be employed - repeating pattern in the frequency domain. Schematic 3A to 3C are diagrams illustrating an example of flag pattern, however, exemplary repeating pattern may include, but are not limited to FIGS. 3A to 3C respectively show a comb-shaped stripe pattern, sawtooth pattern, and a checkerboard pattern, no simple frequency-domain reuse pattern signal can realize the function of the pattern signal. Flag patterns may be used to carry some simple information, a comb-like stripe pattern as an example, the position of the stripe width and may, for example, to distinguish between different operators or carry some other simple information.
[0067]
However, since the flag pattern patterns simple and therefore very limited information carried, to achieve information exchange between operators for the purpose of effectively avoid conflict, simply repeat the pattern carries information is not enough, so in order to save storage resources, energy pattern should be coded to carry richer link information. As an exemplary coding method, for example, the position may be coded as energy-carrying 1, without the energy position code is 0, the energy of such a pattern signal can be represented as a binary code sequence, so that the link may represent different information. Of course, those skilled in the art may also be conceivable to use other coding mode, it can be realized as long as the location and duration of the energy to be encoded.
[0068]
And link information in the time domain pattern is specified by the location and duration of the subcarrier to carry energy - energy irregular pattern formed on the plane of the frequency domain for complex carrying link information. Link information may include, but are not limited to, for example, equipment type and serial number of the sending end, the receiving end equipment type and serial number, operator information, and estimating channel occupancy time of one or more. Thus, the signal receiving apparatus coordination between the operators may be resolved by the energy pattern detecting link information, the link information to obtain the relevant pattern is carried, to achieve inter-operator coordination to avoid data transmission conflicts. Link information pattern may include but is not limited to a stripe pattern, a bar code pattern and a two-dimensional code pattern, and any irregularities in the time domain - frequency domain energy pattern can be used to implement the functions of the pattern signal. 4A to 4C illustrate an example of link information in the form of a pattern, e.g., FIG. 4A shows a specified example of binary-coded stripe pattern, FIG. 4B shows a simple example of the barcode pattern, and FIG. 4C shows a simple two example-dimensional code pattern.
[0069]
It should be noted, the above logo design and link information patterns can be used alone or in combination, taking into account the future of wireless network deployment denser, more may need to be exchanged more accurate information between operators in order to achieve better coordination purpose, so embodiment of the present disclosure, the use of these two binding pattern signal. That is, the flag signal flag preamble pattern used as an inter-operator coordination signal to inform the operator coordination between the start signal, and may also carry some simple link information, and link information mark pattern may occur after a pattern before the data stream, for carrying more complicated link information. The transmission side apparatus can transmit the data stream immediately after the end of the broadcast link information pattern.
[0070]
As described above, considering the continuity and compatibility of standard equipment, inter-operator energy pattern signal as the signal to solve the difficulties of coordinating the detection signal received and demodulated, effectively realize the different carriers on the unlicensed frequency band Information exchange. Moreover, it should be noted that the length can be set to the time domain and frequency domain width of the inter-operator coordination signal depending on the circumstances, and can be set specific inter-operator coordinating signals used according to the future development trend of wireless network operators and the actual situation pattern, which is not limited in the present disclosure.
[0071]
It should be noted in the description of the present disclosure, preferably, the wireless communication system is a system LAA, but the present disclosure is not limited to this, but can also be applied to the device-to-device (Device to Device, D2D) communication system, LTE- interconnection system WiFi wireless communication system, in other words, as long as the time - frequency domain signals of the system is limited, can achieve energy pattern of the present invention.
[0072]
Moreover, it should be noted that in the LAA system, the respective equipment operators typically use the same OFDM symbols, thus, problems between various operators such equipment operators usually unified coordinate signal is not present. However, when applied to other communication systems other than the LAA system, e.g., WiFi LTE-interconnection system, for example, it is assumed for the LTE system, OFDM symbol 15KHz bandwidth, duration of 72 microseconds, for a WiFi system , the bandwidth is 312.5 kHz, the duration of 4 microseconds, if the device wants to send the two systems similar to each other carriers coordination signal, the device may transmit the LTE system as a set of 20 subcarriers, the device may be a WiFi system transmission duration of 18 symbol length, the signal to achieve unity. It should be understood, the signal bandwidth and set forth herein are merely for convenience duration given by illustration and not limitation, the energy detection, can detect bandwidth and duration may be not so strictly limited.
[0073]
That is, preferably, coordination unit 104 may be further configured by adjusting the number of sub-carriers and / or duration of the inter-operator coordination signal transmission signal to the signal to achieve harmonization with other operators between the operator devices. Further, preferably, the coordination unit 104 may be further configured to adjust the number of inter-operator coordination subcarrier signal in accordance with a least common multiple or the greatest common divisor of the duration of the number of inter-operator coordination sub-carrier signals and / or signal transmission and / or duration of signal transmission.
[0074]
Moreover, it should be noted that the apparatus described above with reference to FIG. 1 function unit 100 may be separate physical or logical entity, or to different functional units may also be the same physical entity (e.g., a central processing unit (CPU), a large-scale integrated circuit (ASIC), etc.) to achieve. Further, the apparatus 100 may be located at the transmission side device or may be a transmission side apparatus itself, in the case where the transmitting apparatus 100 is a terminal device itself, the device 100 may further include a communication unit such as a transceiver, for realizing the device 100 with other signal transmission between devices.
[0075]
Next, FIG 5 depicts the function of the receiving side apparatus configuration example will be described. FIG 5 is a block diagram illustrating a functional configuration example of a receiving end of a wireless communication system according to an embodiment of the disclosed apparatus. Preferably, the wireless communication system is a system LAA.
[0076]
5, the apparatus 500 according to this embodiment may include a channel detecting unit 502 and coordinate unit 504.
[0077]
Channel detecting unit 502 may be configured to detect whether an unauthorized reception of the channel on the idle frequency band, to ensure proper coordination of the received signal between the transmitting side of the broadcast operator. DETAILED channel detection method described above can be found in the corresponding position, which is not repeated herein.
[0078]
Preferably, if the channel detecting unit 502 detects reception of the channel is idle, the receiver may correctly received inter-operator transmitting side broadcast coordinating signal, and if it is detected at this time the receiving end of the channel is busy and thus can not receive signals, may be by e.g. licensed band inform the sender, such that the UE stops transmitting broadcast operator coordination between signals. At this time, transmission end notification to the coordination unit 104 may receive an indication of the channel from the receiver is busy at the receiving end, the transmitting end so that the stop signal coordination between the broadcast operator.
[0079]
Coordination unit 504 may be configured in a case where the receiving side the channel is idle, a predetermined time after the receipt of coordination signals between the transmitting side broadcast operators, so that the receiving end coordination with operators from the sender signal broadcast shortened synchronism inter-operator coordination signals to be used to implement information exchange between different carriers device.
[0080]
Specifically, the receiving side can be known after the coordination between the signal received by the transmitter to broadcast operator, the transmitting side has successfully performed the channel LBT and received, so that the coordination unit 504 may be received by the receiving end in a short inter-operator after coordinating signal (e.g., a period of pre-flag pattern) waiting for a small delay, and then begins to shorten coordination signals between simulcast carrier. Wait here a small delay is used to confirm the transmitting side is coordinated between operators broadcasting signal, and the delay can be set in advance according to the actual situation. It should be noted here the so-called "shortened inter-operator coordination signal" refers to the inter-carrier between the receiving end broadcast operators coordinate signal and sending end broadcast coordinate signal is fully synchronized, except between the receiving end broadcast operators late coordination signal coordination between the sender signal begins broadcasting operators, therefore, compared with short duration signal coordination between the sender broadcast operators.
[0081]
Figures 6 and 7 illustrate the transmitting side between the broadcast operator exemplary forms of coordination between the signal and the receiver signal coordination broadcast operator. 6 and 7, wherein the gray shading indicates the inter-operator coordination preamble flag signal pattern, a vertical line shading indicates the inter-operator coordination link information pattern signal, and signals the end of coordination between operators Thereafter, the transmitting end starts the transmission data streams, and the receiving side starts receiving the data stream. As can be seen, between the receiving end of the broadcast operator side transmits a broadcast signal and coordination of inter-operator coordination full synchronization signal, only a start time of a little late, so that inter-operator coordination shorter length signal.
[0082]
Preferably, according to the actual situation, it can be adjusted to the above-described operation. For example, to ensure that the receiver can timely reception of data, coordination unit 504 may be such that the receiving end before the end of broadcasting shortened coordination signals between operators, i.e., prior to the transmission side end coordination signals between a broadcast operator, to be ready to receive the data stream.
[0083]
As described above, since the inter-operator coordination energy pattern signal is a signal, thus transmitting and receiving ends at the same time between the broadcast operator coordination signal causes a corresponding position on the energy of the inter-operator coordination signal is superimposed, thereby increasing the inter-operator coordination signal coverage and intensity, without causing superposition error, and thus will not interfere with inter-operator coordination for the received signal.
[0084]
It will be appreciated, the link information can be detected in the current transmission after receiving the inter-operator coordination signal coordination signal, the other device near the end of the transmission between the transmitting side by a broadcast operator, to determine if the current link does not affect its own transmission received, you can create a new transmission link, so can improve channel utilization. In contrast, for the conventional apparatus, simply by energy detection determines the channel state can not be determined near the link device receiving or transmitting only determines the channel busy, remain muted when the channel is busy, waiting for the channel is idle, which for surrounding the transmitting end in terms of equipment is a waste of resources. On the other hand, by receiving the broadcast operator coordination between the signal terminal, a nearby device upon receiving a signal coordination between the operator detects a current transmission link information, if it is determined the current link itself can affect the transmission received, the receiving terminal may wait for the channel after transmission or idle then another channel is selected for transmission, so that transmission efficiency can be improved.
[0085]
It should be noted, the devices described above with reference to FIG. 5 in the functional unit 500 may be separate physical or logical entity, or to different functional units may also be the same physical entity (e.g., a central processing unit (CPU), LSI (ASIC), etc.) to achieve. Furthermore, the device 500 may be located in the receiving end device or may be a receiving end device itself, in the case where the apparatus 500 is a receiving terminal device itself, the device 500 may further include a communication unit such as a transceiver, means for realizing other 500 signal transmission between devices.
[0086]
Figure 8 shows an example of a signaling exchange using inter-operator coordination signal. FIG 8 is a schematic diagram showing an example signaling exchange coordination signals using inter-carrier embodiment of the present disclosure.

It should be noted, in the example shown in FIG. 8, LAA to uplink transmission system as an example, i.e., the transmission side to the user equipment (the UE), and the receiver is a base station (the BS), it gives the operator during use a case where a signaling signal coordinated interaction between the user equipment and the base station, but this is merely an example, and not limitation, the present disclosure may obviously be applied for downlink transmission, device to device (device to device, D2D) communication, LTE-WiFi scenes such interconnection, and the same applies to the following description.
[0088]
As shown, in the case of uplink transmission, the user equipment first transmits an uplink scheduling request to the base station 8 to obtain an uplink transmission resource, the base station may then send an uplink scheduling grant (i.e., UL grant) to the user equipment in accordance with channel conditions. User equipment LBT after receiving the uplink scheduling grant for the transmission of the channel to ensure that the transmission of the channel is idle and the sending device will not interfere with the existing link, while the base station receiving end channels LBT to ensure the reception of the channel is idle . In the case where the transmitting side is detected idle channel, among the user equipment operator starts broadcasting signal coordination and synchronization between the base station starts broadcasting operators coordinating signals received after the first few slots of inter-operator coordination signal. After the end of the broadcast signal coordination between the operators, the user equipment transmits data streams to the base station.
[0089]
It will be appreciated, the signaling interaction process shown in FIG. 8 is for describing the use of inter-operator coordination signal given simple example of interaction, it will be apparent to those skilled in the art will be modified in accordance with the process of the principles of the present disclosure. For example, as described above, in the case where the base station detects the reception of the channel busy, the base station may notify the user equipment by the licensed band so that the user equipment stops coordination signals between broadcast operator.
[0090]
In order to facilitate coordination among the signal carriers understanding how to apply the inter-operator coordination, next with reference to FIGS. 9 to 13 described interaction scenarios between operators in the case of coordinating signals between applications and the present disclosure operators corresponding signaling examples of the interaction process.
[0091]
FIG 9 is a schematic diagram illustrating an example interaction scenarios between operators embodiments of the present disclosure.
[0092]
9, the presence of the operator and the user equipment UE1 base station BS1 and base station BS2 carrier 1 and the user equipment UE3 and UE2 2 In this example scenario, where the individual devices are indicated by circles centered power range . Here an example is still the uplink transmission, the user equipment UE2 listenable coordination signals between the base station BS1 receives the data stream prior to broadcast operator, so that the user equipment UE2 may be obtained by analyzing the inter-operator coordination signals with the base station BS1 link information of the link between a user equipment UE1 to the base station BS2, to a reasonable scheduling base station BS2 in order to avoid an impact link, in order to achieve the coordination between operators.
[0093]
FIG 10 is a diagram showing an example of a signaling interaction process in the inter-operator scenario example shown in FIG. 9.
[0094]
Signaling interaction process shown in FIG. 10, where the signaling interaction between the user equipment UE1 and the base station BS1 and 8 previously described signaling interaction process of the same reference and will not be repeated. Here will be described in detail mainly involved in signaling inter-operator interaction. As shown, the vicinity of the base station BS1 carrier user equipment UE2 2 may parse 10 pairs of inter-carrier base station BS1 receives the broadcast signal to obtain the coordinate information of the link 1, and link information of 1 to base station BS2, the base station BS2 if the link will affect the transmission link 2 of the link 1 according to the determination information, the base station BS2 may wait after the end of transmission on the rescheduling the user equipment 1 the UE2 link (i.e., uplink grant signaling transmission ). Signaling interaction process between the user equipment UE2 to the base station BS2 may be similar to above with reference to FIG signaling exchange coordination signals between 8 using the carrier described, or may not use the coordinate signals between operators, but, as the prior art as in the user equipment UE2 uplink data transmission immediately after the detection of an unauthorized channel is idle on the band.
[0095]
Alternatively, instead of signaling interaction process shown in FIG. 10 as scheduled user equipment UE2 waits again after the end of a transmission link, the base station BS2 may be selected at this time does not affect the scheduling of other user equipment 1 link. For example, as shown, the user equipment UE3 from the base station BS1, the base station BS2 thus determines if transmissions on link 2 will affect the link 91, you can also schedule the user equipment UE3 establish a link 3, and on the uplink transmission 3 1 does not affect the link. FIG. 11 shows a signaling interaction process in this case.
[0096]
FIG 11 is a diagram showing a scene in the example shown in FIG. 9 is another example of a signaling interaction between the carriers.
[0097]
As shown, the signaling interaction process shown in FIG. 11 and 10 is substantially similar to 11, except that only the base station BS2 after receiving the information of the link 1, the transfer is not selected wait for the link 1 after the user equipment and then scheduling the UE2, UE3 but schedule the user equipment to establish a transmission link 3, and 3 on the uplink transmission does not interfere with a link. A signaling interaction process between the user equipment UE3 and the base station BS2 may be described above with reference to FIG. 8 using a carrier similar signaling exchange coordination signals, or may not use the coordinate signals between operators, but, as the prior art as in, the user equipment UE3 uplink data transmission immediately after the detection of an unauthorized channel is idle on the band.
[0098]
FIG 12 is a diagram showing another example of inter-operator embodiments of the present disclosure interactive scene.
[0099]
12, the presence of the operator and the user equipment UE1 base station BS1 and base station BS2 carrier 1 and the user equipment UE3 and UE2 2 In this example scenario, where the individual devices are indicated by circles centered power range . Here an example is still the uplink transmission, the base station BS2 can listen to the coordination signals between user equipment UE1 before transmitting data stream in a broadcast operator, and the user equipment UE2 may listen to the inter base station BS1 receives the data stream prior to broadcast operator coordination signal, this ensures that after a link between the base station BS1 the UE1 and the user equipment 1 is established, the user equipment UE2 will not send an uplink scheduling request to the base station BS2 to affect transmission on a link. Base station BS2 may be rescheduled according to the inter-carrier user equipment UE1 coordinating signals broadcast at an appropriate time in order to avoid the effects of the user equipment UE2 link 1, thereby achieving coordination between operators.
[0100]
FIG 13 is a schematic diagram of an example of a signaling interaction process in the inter-operator scenario shown in the example shown in FIG. 12.
[0101]
Signaling interaction process shown in FIG. 13, the signaling interaction between the user equipment UE1 and the base station BS1 signaling exchange of FIG. 8 described with reference to the same procedure as before, will not be repeated. Here will be described in detail mainly involved in signaling inter-operator interaction. 13, since the inter-base station BS2 can listen to a broadcast operator user equipment UE1 coordinating signals, so different from the signaling interaction process shown in FIG. 11, only the base station BS2 can be known by analyzing the inter-operator coordination signal 1, the link conditions without receiving the link information of the user equipment UE2, then so scheduled user equipment UE2 after the base station BS2 may be transmitted on the link 1, to avoid conflicts. Signaling interaction process between the user equipment UE2 to the base station BS2 may be similar to above with reference to FIG signaling exchange coordination signals between 8 using the carrier described, or may not use the coordinate signals between operators, but, as the prior art as in the user equipment UE2 uplink data transmission immediately after the detection of an unauthorized channel is idle on the band. Alternatively, in the exemplary scenario shown in FIG. 12, may be as described above with reference to FIG. 11 described as a signaling interaction process, substituted a signaling interaction process 13 in the base station BS2 waits for link 1 the transmission scheduling after the user equipment UE2, the base station BS2 can also choose at this time does not affect the scheduling of the user equipment UE3 1 link for transmission to establish a link. Similar specific signaling interaction process shown in FIG 11, will not be repeated.
[0102]
It may be a case where uplink transmission coordination signal according to an inter-operator other operators device broadcasts based coordination unit 104 described above signaling interaction process, preferably, the transmitting side apparatus 100, the control sender sends an uplink scheduling request to the base station and link information may also be reported and determined according to the inter-operator device broadcasts other operators coordinating signals to the base station to perform uplink scheduling by the base station. On the other hand, the receiving side device coordination unit 504 may be 500 in the case of uplink transmission, uplink scheduling and coordinating the signal transmission end or the link information reports in accordance with the inter-operator other operators broadcasting equipment. In this way, the use of inter-operator coordination signal be easily achieved coordination between the operators, to avoid data transmission conflicts, thereby improving overall system performance.
[0103]

For example, in the case of downlink transmission, as the transmission side base station need not send a scheduling request after the permission before subsequent LBT, between broadcasters coordinating operation signal, and coordinating signals according to an inter-operator other carrier device is broadcasting Analyzing the case where other users can affect the current transmission link is a link exists, after the end link transmission base station may then wait for the existing equipment of the user data transmission, or may not affect the existing link equipment to establish a link for transmission. Signaling interaction process in other scenarios are suitable variant of the art according to existing knowledge in the art, and the principles of the present disclosure can be implemented, which is not enumerated herein.
