detailed description
[0028]
It will now be described with reference to the accompanying drawings of embodiments of the present invention. Elements and features of the elements and features described in one figure or one embodiment of the present invention may be illustrated embodiment with one or more other drawings or embodiments described combination. It should be noted that for purposes of clarity, the drawings and the description is omitted irrelevant to the present invention, shown and described are known to those of ordinary skill in the components and processes.
[0029]
As shown in FIG. 1, an electronic apparatus for wireless communication according to the present embodiment 100 includes a processor 110. As described in conjunction with specific embodiments later, the electronic device 100 may operate as a base station or user equipment.
[0030]
Further, to be noted that, although the first determination unit 111 to separate the accompanying drawings shows a dashed box 110 and a second processor unit 113, it should be understood that the first determination unit 111 and second determination unit 113 the functions can also be implemented as a whole by the processor 110, and not necessarily by the processor 110 in the separate components to achieve practical. Further, although to a block in FIG processor 110 is shown, however, the communication device 100 may include multiple processors 111 may function as the second determination unit 113 and a first determining unit across multiple processors, so that the a plurality of processors operable to perform these functions.
[0031]
The first determining unit 111 is configured to respond to a first user device adjacent to the direct communication demand service, the first user device determines the current carrier aggregation (carrier aggregation) state.
[0032]
When the user equipment through carrier aggregation embodiment communicates with a base, for example, downlink carrier aggregation, the base station through the primary cell (Pcell, Primary Cell) corresponding to the primary component carrier (PCC, Primary Component Carrier) transmitting primary control channel so that to a user equipment, including resource scheduling indication of a secondary cell (Scell, secondary cell) corresponding to the secondary component carrier (SCC, secondary component carrier), whereby the cross-carrier scheduling can be realized (cross scheduling), on the other hand, in uplink carrier aggregation, generally only the primary user equipment transmits uplink control information to the cell by the base station. No current standardization discussion relates to carrier aggregation and the adjacent concrete work services, a user device during the direct communication superimposing two techniques typically communicate with the base station in a time division multiplex manner and the other user equipment on the same carrier, but such work is clearly inefficient, the present invention is intended to give some solutions.
[0033]
As described above, the electronic device 100 may operate as a base station or user equipment. For example, in the case of the electronic device 100 operates as a base station, when a first user equipment an RRC connection with the base station when the service to be adjacent to the direct communication, the first user device may send indication information corresponding to the base station, and the base station corresponding to the indication information, for example, a first user device determines the current state of carrier aggregation according to the information held by the base station. Further, in the case where the electronic device 100 is a first user device itself, that direct communication needs and services directly adjacent to the current state of carrier aggregation.
[0034]
The second determination unit 113 is configured to aggregate state based on the first user device carriers, determines a radio resource configuration of the first user device. Wherein the radio resource configuration for the first user device to communicate directly adjacent service.
[0035]
According to one embodiment, the second determination unit 113 may be configured as a carrier aggregation based on the determined state and the capability of the first user equipment determines whether the current carrier aggregation reconfigured to enable communication services directly adjacent to, wherein the carrier aggregation state may include polymeric component carrier (CC) number. For example, a first user equipment device may include the ability to support an uplink capacity, for example, an uplink multi-carrier aggregation capability (e.g., uplink carrier aggregation is supported, the maximum number of uplink carriers support carrier aggregation), respectively, carrier aggregation may include the current state of the number of uplink component carriers.
[0036]
Further, reconfiguration of the current release carrier aggregation may comprise at least one polymerizable component carriers, reconfiguration may comprise one of the aggregated component carriers are configured to communicate directly adjacent to the service.
[0037]
More specifically, the second determination unit 113 may be configured, for example, in the case where the number of aggregated component carriers reaches a predetermined threshold, releasing at least one aggregated component carriers and one of the component carriers configured to communicate directly adjacent to the service. For example, the predetermined threshold is a maximum number of carriers, for example, the device capability of the user equipment is capable of supporting determined.
[0038]
According to this embodiment, in the case of carrier aggregation, the UE may be scheduled directly communicating on a secondary carrier ProSe (SCC) has been used to facilitate, for example, for measuring time, and further reduce the cost configuration of a radio communication resource.
[0039]
Next, the operation of the electronic device 100 as an example the case where the base station, will be described by way of example of carrier aggregation of reconfiguration to the UE. For example, the base station can be accessed via the media control (MAC) signaling bitmap (Bitmap) will notify the current form of carrier aggregation reconfiguration to the UE. Alternatively, the same may be a RRC signaling (e.g., the RRCConnectionReconfiguration) to achieve a different configuration in the notification with information elements (IEs), such as information about the release of the secondary carrier (sCellToReleaseList) and a secondary link configuration information about ProSe (SL -CommConfig), wherein the same two carrier frequencies contained in IE to be released near the carrier frequency and the service communicate directly.
[0040]
More specifically, for example, to a conventional MAC control element (CE) payload (payload) consistent with the structure, may be used as shown in Table 8-bit data of 1 bit to indicate the relevant component carrier.
[0041]
Table 1
[0042]
[Table 0001]
C7 C6 C5 C4 C3 C2 C1 1

[0043]
For example, 8-bit bitmap cell is sufficient to represent as 8 ProSe component carrier, but may use only a portion of bits wherein on demand. In the present example, the last bit is set to 1, this purpose is to identify the signaling indication is the signaling ProSe
[0044]
For the first 7 bits, the 0 indicates that the corresponding cell does not carry the service communicate directly ProSe; represents a cell carrying the corresponding service ProSe direct communication.
[0045]
For example, if C7 = 1, it indicates ProSe establish direct communication on the PCC primary component carrier; if C6 = 1, it indicates ProSe establish direct communication on the secondary component carrier SCC1. In some example embodiments may be provided for the first seven bits at most one bit is 1 and other bits are set to 0.
[0046]
Further, for example, 8 bits may be used partially or all of them for encoding. For example, 8 bits can represent the case of encoding at least 256 cells, but may use only a portion of bits wherein on demand. For example, 3 bits "001" represents the UE PCC, "010" and so on behalf of the UE's SCC1, as shown in Table 2.
[0047]
Table 2
[0048]
[Table 0002]
Indicator 0/1 0/1 0/1 NULL NULL NULL NULL

[0049]
Further, according to one embodiment, the second determination unit 113 may be configured to preferentially select the aggregated component carriers or low channel quality non-activated component carrier or to be released as a CITIC adjacent carrier direct communication service.
[0050]
By this embodiment, the current carrier aggregation can simultaneously reconfigured to enable communication services directly adjacent can be reduced without affecting the existing communication by the carrier aggregation.
[0051]
According to another embodiment, the second determination unit 113 may be configured to be adjacent to the first user equipment a second service communicate directly with the user equipment is using the same one of the first polymeric component carriers in a user equipment used in the the case of carrier, the same carrier for adjacent carrier selection between a first user equipment and second user equipment in communication services directly.
[0052]
By this embodiment, since the service communicate directly adjacent to both the user equipment uses the component carriers currently in use will be adjacent to the direct communication services, thereby facilitating further reduce the measurement time and radio resource configuration and the like used for communication overhead.
[0053]
Next, the operation of the electronic device 100 as an example the case where the base station, one of the described polymeric component carriers configured for communication services directly adjacent the exemplary embodiment, the foregoing relates to some aspects of the embodiments in this example, it should be It noted that the invention is not limited to the specific details of the examples.
[0054]
When it is desired to select from a conventional component carriers used for communication services directly adjacent to, for example, according to the channel quality sounding reference signal (SRS) reported by the user, comparing each component carrier base stations, and select a channel quality is poor component carrier adjacent the service communicate directly used. In particular, the case where the same component carrier in the UE between two directly adjacent communication service to be performed, this may be a component carrier for carrying communications services directly adjacent to the channel quality may not be considered, so that a smaller overhead complete the configuration of two of the UE. After the carrier component selected from the existing UE the component carrier for carrying communication services directly adjacent to, the base station may, for informing the user of the signaling device transmits to the user equipment signaling indicating the component carrier on which service adjacent component carriers directly communication.
[0055]
More specifically, assuming that the UE1 cellular communications on the component carrier CC1, CC2, CC3, CC1 is a PCC, CC2, and CC3 are SCC. The base station may compare the CC2 and the CC3 uplink channel quality is poor and selects one, e.g. CC3, CC3 will be determined for communications services directly adjacent.
[0056]
As another example, it is assumed that the UE1 PCC CC1, SCC1 is CC2, SCC2 is the CC3, and the CC1 is a PCC in the UE2, and no SCC. Since the UE1 and UE2 use the same carrier CC1, CC1 can thus be used for the UE1 and UE2 communicate directly adjacent service.
[0057]
After the carrier is selected, the base station transmits signaling to the user indicating the component carrier, this signaling is used to inform the user near the service to establish direct communication on which CC.
[0058]
Figure 9 shows a signaling flow example corresponding to the example.
[0059]
In Step 1: UE2 adjacent the service request to the base station direct communication with UE1, for example, the request ProSe UE Information indication;
[0060]
In Step 2: the base station determines carrier aggregation reconfiguration manner, e.g., adding a new component carrier to select one or UE1 existing component carriers for the UE1 communication services directly adjacent;
[0061]
For example, in case of determining to select one component carrier where the existing service communicate directly adjacent to, and in step 3: the base station selects one of the component carriers for the UE1 communication services directly adjacent;
[0062]
Step 4: the base station transmits signaling indicating the component carrier (e.g. the control unit indicated by the MAC layer) to the UE1;
[0063]
In Step 5: The base station sends an RRC connection reconfiguration signaling to UE2;
[0064]
In Step 6: UE1 transmits to the base station indicating the component carrier in response to signaling received;
[0065]
In Step 7: UE2 sends an RRC connection reconfiguration in response to the base station;
[0066]
For example, by the base station resource block physical downlink control channel (PDCCH) assignment to UE1 and UE2 in the selected carrier;: 8 at step
[0067]
Perform proximity communication services directly UE1 and UE2: in step 9.
[0068]
It is noted that, in some cases, components of the above-described step 4 of the base station carrier wave indicating the UE1 is not necessary. For example, in the present adjacent to the direct communication services Another way is to directly adjacent the service discovery to discover other nearby UE on the radio signal through direct interfaces PC5. In an example of this finding, UE2 transmit discovery signals, and to receive and found only UE1, without sending information to the UE2, and therefore unnecessary to make the configuration of component carriers.
[0069]
The foregoing describes one of the aggregated component carriers configured in the embodiment adjacent the communications services directly. Further, according to some embodiments, the second determination unit 113 may be further configured to determine from a predetermined first carrier set for carrier services directly adjacent the user equipment performs communication.
[0070]
More specifically, the second determination unit 113 may be configured as a carrier in the case of a polymerization number of component carriers using a first user equipment does not reach a predetermined number, to be selected from the set of carriers for a proximity communication services directly ( add a new carrier), wherein the carrier set may include a base station serving a first user device and not be able to schedule a first user equipment and second user equipment using a plurality of carriers to be adjacent to the first user equipment for communication services directly .
[0071]
In the case of the electronic device 100 operates as a base station, for example, can be selected by way of the following services directly adjacent the carrier to use for communication:
[0072]
For each group of user equipment may be used to communicate service communicate directly adjacent the carrier component randomly select a carrier for component communication services directly adjacent;
[0073]
For each set of a user equipment for a communication service may be used to communicate directly adjacent the component carrier, the carrier is selected to be used for direct communication according to the neighboring service carriers use, for example, the use of a carrier may include the number of user equipment this is using the cellular communication component carriers;
[0074]
For each set of a user equipment for a communication service it may be used to communicate directly adjacent the component carrier, according to the channel quality on the optional component carrier of the set of historical measurements reported by the user equipment, e.g. RSRP of, select the lower channel quality measurement history component ProSe carrier for direct communication.
[0075]
Next, with reference to specific exemplary embodiments described modes for determining the service communicate directly adjacent the carrier from a predetermined set of carriers.
[0076]
According to one embodiment, the second determination unit 113 is further configured according to other users other than the first user equipment device to select a serving base station for use in a carrier of a predetermined set of carriers to be used for direct communication and services adjacent carriers.
[0077]
For example, for a user equipment to be adjacent to each set of communication services directly alternative carriers may correspond to a list, the list can include this group of user equipment can be used for all component carriers of the communication services directly adjacent to, the component carriers may be e.g. It can include a base station assigned to be performed in addition to the set of all component carriers of the communication services directly adjacent the user equipment is using a carrier other than the component.
[0078]
Selected component carriers according to the component carrier where the aim is to use as little interference component carrier adjacent the service communicate directly.
[0079]
More specifically, the use of a particular carrier may include aspects of one or more of:
[0080]
The number of users currently using the device for a particular carrier cellular communications, for example, may preferentially select a smaller number of carriers that serve to reduce interference between adjacent direct communication with the cellular communication;
[0081]
Are in particular the number of carriers serving the user equipment near direct communication, for example, may preferentially select a smaller number of carriers to reduce the interference between adjacent service a direct communication link;
[0082]
Coverage of a particular carrier, for example, cover a smaller range of selected component carriers (i.e., having a higher frequency carrier);
[0083]
How often a particular carrier to be used in the history, for example, may select a lower frequency of the carrier being used; and
[0084]
The total duration of a particular carrier to be used in the history, for example, may be selected from the total time length of the minimum carrier to be used.
[0085]
The selection by the use of a carrier adjacent the service communicate directly adjacent to help reduce the impact of cellular communication services in direct communication.
[0086]
FIG 10 shows a flowchart illustrating a signaling by the base station selected under a predetermined set of carriers used for carrier services directly adjacent to the communication situation.
[0087]
In Step 1: UE2 adjacent the service request to the base station in direct communication with the UE1;
[0088]
In Step 2: the base station determines carrier aggregation reconfiguration manner, e.g., adding a new determination of the UE1 component carrier;
[0089]
In Step 3: the service for the adjacent base station direct communication carrier selected from a predetermined set of carriers;
[0090]
In Step 4: the base station transmits to the UE1 and UE2 RRC connection reconfiguration signaling;
[0091]
In Step 5: UE1 and UE2, the base station sends an RRC connection reconfiguration response;
[0092]
E.g. resource block selected by the PDCCH allocated to UE1 and UE2 carrier base station;: In Step 6

[0094]
Further, according to one embodiment, the carrier may be for the reference signal received power carrier measurements carrier set (RSRP) to select a direct communication according ProSe.
[0095]
FIG 2 shows a configuration example of electronic equipment for wireless communication according to the present embodiment. As shown, the electronic device 200 includes one or more processors 210, processor 210 includes a determining unit 211, an access unit 213 and the selection unit 215. Wherein determining configuration unit 211 and a first determining unit 111 1 is described with reference to FIG similar access unit 213 and the selection unit 215 corresponds to the second determination unit described with reference to FIG. 1, 113
[0096]
Access unit 213 is configured to access a measurement result for a reference signal received power of the carrier in the set of at least a portion of the carrier.
[0097]
The selection unit 215 is configured to select a carrier for a proximity service measurement result of direct communication, wherein the preferred low carrier reference signal received power. Conventional carriers selected in different ways, according to an embodiment of the present invention may be selected low measurement value of the carrier, because the radio link quality is measured on the carrier between a UE and a base station, however, the purpose is to choose direct communication between the UE and the UE, so the measured values ​​of the corresponding measured value of the low carrier surrounding cellular UE is low, a lower probability of being selected for a cellular communication carrier, and thus more suitable for lower interference between the UE direct communication.
[0098]
It is noted that access to the results of the measurement unit 213 may include access to access history of the measurement results for the reference signal received power of different carriers. In the case where the operation of the electronic apparatus 200 according to the present embodiment is a base station, for example, the measurement result may be obtained by accessing its historical data stored by itself, or may report the measurement results for the respective carrier history by the user equipment. In the case of the electronic device 200 operates as a user device, such as the measurement result may be obtained by accessing the history data which is stored at the service station, or access the historical measurements stored therein.
[0099]
On the other hand, access to access unit 213 pairs of measurements may comprise measurements in real time to the user equipment access to the predetermined carrier. For example, in the case of the electronic device 200 operates as a base station, which may be used as candidate services directly adjacent the carrier of communication to the user equipment (as will be described with reference to the embodiment of FIG. 3), in other words, the user equipment specific measurement configuration, and acquires the RSRP measurement result candidate carrier by the user equipment. In the case of the electronic device 200 operates as a user equipment may select a carrier based communication services directly adjacent to the measurement results of candidate carriers.
[0100]
Further, according to some embodiments, the measurement results may not all candidate carriers to select a carrier for a proximity-based communication services directly.
[0101]
For example, according to one embodiment, the selection unit 213 may be configured to obtain a candidate carrier when not in a predetermined time period in the case of measurement results of all carriers have been selected from the measurement results obtained for the carrier to be directly adjacent to the service carrier communication.
[0102]
In the case where carrier detection result is obtained, for example, below a predetermined threshold of the eligible, the corresponding carrier selection service to be used for direct communication adjacent to another embodiment, the selection unit 213 may be configured in accordance.
[0103]
According to yet another embodiment, the selection unit 213 may be configured as a case where the detection result obtained is continuously lower than the predetermined threshold value within a predetermined period, the carrier will be selected as appropriate to be used for direct communication adjacent the serving carrier.
[0104]
By the above-described embodiment, the detection efficiency can be further improved and the selection candidate carriers.
[0105]
Next, with reference to specific exemplary embodiments described above, specific examples of these include various aspects of the above-described embodiments. It is understood that the invention is not limited to the specific details of the following examples.
[0106]
First, the base station for each group to be directly adjacent to serving the user equipment generates a communication carrier alternative list, which may comprise a carrier of the group of user equipment may be used for all communications services directly adjacent. As described above, the base station may be ordered according to the usage of each carrier of the available carriers. For example, for close to UE1 and UE2 consisting of direct communication services to users:
[0107]
table 3
[0108]
[Table 0003]
Optional carrier list
CC 5
CC 6
………
CC n

[0109]
Which CC5, CC6 ... ascending order.
[0110]
To prevent too long measurement user equipment cause excessive delay timer may be provided:
[0111]
When the timer is timeout, the user equipment stops the measurement and report the measurement results has been completed.
[0112]
For example, by the base station signaling RRCConnectionReconfiguration list of alternative carriers to the user equipment.
[0113]
The user equipment after receiving the list of alternative carriers, RSRP measurement starts sequentially for each carrier. For example, the timer time measured RSRP of the CC5-CCn had, as shown in Table 4.
[0114]
Table 4
[0115]
[Table 0004]
Optional carrier list RSRP
CC 5 RSRP 5
CC 6 RSRP 6
……… ………
CC n RSRP n

[0116]
After the measurement, the user equipment can directly report the measurement result to the base station selected by the serving base station to communicate directly adjacent the carrier. Alternatively, the user equipment may choose services directly adjacent the carrier for communication based on the results, e.g. CC6, and the selection result is reported to the base station.
[0117]
After the eNB receives the information of the UE2 through the RRC Connection reconfiguration CC6 UE1 and UE2 is assigned to carrier service as a near direct communication.
[0118]
Further, if the optional list contains more carrier carriers, the measurement procedure time and energy consumption of the UE may be large. Thus, measurement event may be defined as follows: the measured RSRP of the carrier below a certain threshold, the threshold may be predefined.
[0119]
The UE may according to the priority level of alternative carriers in the list of carriers, the carrier measured sequentially. Condition and can be defined as follows:
[0120]
Event entry conditions: Mr threshold Th
[0122]
Wherein, Mr is the RSRP measurement result of current carrier.
[0123]
After entering the event, UE may trigger a set time of the current carrier, and in the trigger time, the continuous measurement of the current carrier RSRP.
[0124]
When UE continuously measure the current carrier, UE maintains the measure to other CC.
[0125]
If the current carrier has to satisfy a predetermined requirement in the trigger time, the UE stops the measurement and report the current serving carrier adjacent to the carrier for direct communication.
[0126]
If the trigger in time, can not always meet the requirements, then the event exit.
[0127]
Next, with reference to FIG. 11 described and measured by the user equipment selecting a carrier of an example process.
[0128]
In Step 1: UE2 adjacent the service request to the base station in direct communication with the UE1;
[0129]
In Step 2: the base station determines carrier aggregation reconfiguration manner, e.g., adding a new component carrier to the UE1;
[0130]
In Step 3: The base station generates a list of alternative carriers;
[0131]
In Step 4: the base station transmits to the UE1 optional carrier list;
[0132]
In Step 5: UE1 RSRP measurement list for alternative carriers carriers, and selecting a service communicate directly adjacent the carrier;
[0133]
In Step 6: UE1 information on the selected carrier to the base station;
[0134]
In Step 7: The base station transmits an RRC connection reconfiguration signaling to the UE1 and the UE2;
[0135]
In Step 8: UE1 and UE2, the base station sends an RRC connection reconfiguration response;

[0144]
Determined from the previously described predetermined carrier set for carrier service communicate directly adjacent to an embodiment. Further, according to one embodiment, the carrier may comprise a dedicated set of a fixed set of carriers adjacent to the direct communication services. In other words, you can set up a special service direct communication carrier level resource pool is adjacent. For each carrier in the set, there may be a corresponding unique resources, such as control of the carrier when the transmission cycle control transmission of the transmission control cyclic prefix length, the sub-link sub-link, link specific sub frequency resource block is configured, the configuration data of the frequency hopping cyclic prefix length, the sub-link sub-link data (configuration data frequency resource sub-link) the allocation of resources selected by the user, and the like.
[0145]
Next, a description is provided in connection with specific exemplary embodiment of the exemplary set of dedicated carrier.
[0146]
According to one set of dedicated carrier arrangement, the carrier set for carrier service communicate directly adjacent the carrier aggregation scenarios, which can be divided into static and dynamic carrier set set of carriers set in two ways.
[0147]
Static carrier set fixed carrier, and is generally narrowband carrier, which is only arranged for communication services directly adjacent to, a cellular communication can not be used; dynamic carrier set may be updated, but the carrier may be set to keep the number of invariant, and it may be used to simultaneously communicate directly adjacent the cellular communication services.
[0148]
The structure of the exemplary set of carriers as shown in Table 5,
[0149]
table 5
[0150]
[0151]
Wherein 0 represents the static type carrier set, represents a dynamic;
[0152]
ID is a carrier of the carriers in the carrier set number;
[0153]
Carrier e.g. Table CC1, CC3, etc. represent respective carrier set in the frequency range of the carrier.
[0154]
Dynamic carrier set according to priority ranking carrier may, for example, the number of multiplexed carriers, the less ordered higher priority.
[0155]
Static carrier set may be broadcast in the SIB, for example, the dynamic carrier set, for example, can be configured by RRC signaling.
[0156]
Next, a more particular description example of a static set of carriers. The base station may reserve a carrier M fixed (M-configurable according to the actual situation), wherein the carrier only adjacent the service for direct communication.
[0157]
For example, M = 3, the reserved resources for CC1, CC2, CC3, for example, the static set of carriers as shown in Table 6.
[0158]
Table 6
[0159]
[0160]
To a carrier, the carrier if the carrier remains fixed ID corresponding relationship, the last column of the table carrier can be removed. Accordingly, the broadcast information about the static carrier set can only broadcast carrier ID, thereby reducing the load of the broadcast information.
[0161]
Further, the initial configuration of the user equipment when the service communicate directly adjacent to a static set of carriers, a plurality of sets may be configured to set different static carriers, the static user device may select which carrier to use their own set.
[0162]
In addition, a set of embodiments, the carrier may also cover the range of services directly adjacent to provide a dedicated communication according to the sub-cell (SCell) according to. The carrier set comprising a plurality of sets of private fixed communications services directly adjacent carriers, wherein each carrier is used for a specific range near the service communicate directly.
[0163]
According to 3GPP TS36.300, Scell ​​coverage will vary. Based Scell ​​certain service coverage is provided directly adjacent to the static set of communication carriers, a corresponding static configuration under each set of carrier coverage, each static carrier set as an initial configuration packet is a static set of carriers.
[0164]
Scell ​​corresponding to the region covered by this service communicate directly adjacent the carrier set contains the Scell ​​shall not overlap therewith in the CC.
[0165]
Below to the case shown in FIG. 13 as an example. As shown, CC1 full coverage 13, CC2, CC 3, CC 4 different coverage. UE1 and UE2 in the coverage CC 2, UE3 CC coverage is 3, UE4 is within range of the CC4. In this case, the following may be provided a plurality of carriers according to the coverage range of the set:
[0166]
CC 2 within the coverage area, a static set of carriers corresponding to a carrier: CC 3, CC 4
[0167]
CC 3 within the coverage area, the static set of carriers corresponding to a carrier: CC 2, CC 4
[0168]
CC 4 within the coverage area, a static set of carriers corresponding to a carrier: CC 2, CC 3
[0169]
Accordingly, the base station transmits the static carrier aggregation information to all UE through SIB may be as shown in Table 7 below:
[0170]
Table 7
[0171]
[0172]
After the UE receives the information packets form a packet pool, consider which carrier selected set, and then select which carrier the carrier set.
[0173]
E.g., UE carrier set selected for the exemplary embodiment, a random selection from the existing set of set of carriers in a carrier, the carrier with its own set of carriers being used for cellular communication are compared, if not the same, takes precedence carrier set, if the same, or more carriers from a carrier containing the same set of randomly selecting a set of carriers.
[0174]
UE selects a carrier from the carrier in conjunction with the exemplary embodiment may include random selection, or the UE may detect the center frequency of each carrier, to select a minimum received signal strength.
[0175]
With the above configuration, it is possible to further reduce interference with communications services directly adjacent the cellular communication.
[0176]
Next, an example configuration of a dynamic set of carriers.
[0177]
To configure dynamic set of carriers to a UE in the base station, the base station may reserve a carrier according to the current multiplexing case, the selection of the M multiplexed carrier set minimum-carriers, wherein the carriers can be simultaneously and directly adjacent to the communication using the cellular communication services .
[0178]
For example, M = 3, are multiplexed by a minimum of three times CC respectively CC5, CC6, CC7 the dynamic carrier set as shown in Table 8 below.
[0179]
