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.
[0038]
Here, also be noted that, in order to avoid unnecessarily obscuring the details of the present invention, the drawings only shows a solution according to the present invention closely related to the device structure and / or processing steps, omitted Further details of the present invention has little relationship.
[0039]

[0040]
FIG 1 shows a block diagram for a wireless communication apparatus according to one embodiment of the present disclosure 100, 100 comprising the device: one or more scheduling units 101, a plurality of user devices is configured in response to the device managed by transmission requirements, a plurality of clusters based on user equipment determines whether the user equipment belongs to the plurality of user equipment can reuse the same physical transmission resource, based on the determination result, the scheduling for a plurality of user equipments corresponding physical transmission resources; and signaling generating unit 102, configured to schedule resources based on one or more scheduling units, and generates the downlink resource scheduling information comprising control information for the plurality of user equipment, wherein the user equipment comprises a user equipment and a cellular D2D user equipment, the plurality of user equipment is divided in advance based on geographic location device to at least one user cluster.
[0041]
For example, in a cellular mobile communication, device 100 may be a base station apparatus eNB or rel-10, such as relay node and the like. Further, here though shows the device 100 is a base station apparatus as an example, but not limited to, device 100 may also be a baseband (cell concept may not be present) in the C-RAN (Cloud-RAN / Centralized-RAN) structure cloud device, such as any one BBU BBU pool communicating with each other at high speed C-RAN architecture. The user equipment described herein, for example, a mobile terminal, vehicles, smart wearable devices.
[0042]
In some examples of the present application, it is assumed D2D user equipment are unicast communication, and the user equipment becomes established D2D user equipment to request the base station is allowed D2D communication. At the same time, a D2D user equipment transmits data to only one user equipment. Thus, it is possible to "user equipment to the D2D" units of physical transmission resource allocation (or scheduling). FIG 2 shows a schematic diagram of a user equipment in D2D performed in units of exemplary resource allocation. Wherein circles represent cellular user equipment (the CUE), and squares represent D2D user equipment (DUE-P), the eNB allocates resources to each UE.
[0043]
For example, one or more scheduling units 101 may be an LTE dynamic resource scheduler standard (36.300 11 Scheduling and Rate Control) specified in. For example, using different dynamic resource scheduler to schedule uplink transmission resources and downlink transmission resource.
[0044]
Wherein the transmission needs of the user equipment may be user equipment uplink transmission needs based on a scheduling request sent (Scheduling Request) is determined, it may be a downlink transmission needs of the user equipment autonomously determined by the base station. One or more scheduling unit 101 in response to the uplink transmission schedule for the user equipment needs a corresponding uplink physical transmission resource, and / or in response to a corresponding physical downlink transmission resource to a downlink transmission schedule for the user equipment needs. Accordingly, in some examples, scheduling unit is divided into an uplink scheduling unit downlink scheduling unit.
[0045]
In this embodiment, the user equipment includes both cellular and D2D user equipment to user equipment, and the user equipment is divided in advance based on location to the at least one user equipment cluster, specific division manner to be described hereinafter carefully. Accordingly, one or more scheduling units 101 to achieve a D2D user equipment physical transmission resources to the user equipment and the cellular unified. It should be noted, here D2D user equipment and the base station can also work for example, and a cellular communication on transmission of control information for the cellular user equipment.
[0046]
During scheduling, a scheduling unit 101 or a plurality of first cluster based on the user equipment determines whether the user equipment belongs a plurality of user equipment can reuse the same physical transmission resource, for example, the determination may be based on such mutual interference between the user equipment as small as possible the rules. In addition, the determination may be based on the current number of available resources (if it may be sufficient without multiplexing), data traffic, QoS requirements, the base station and the user equipment (UE) a radio link and so on.
[0047]
In one example, a user equipment located in the same cluster in a user apparatus using a physical transmission resources orthogonal to each other, while at the same physical transmission resource different user equipment units in the cluster user multiplexing. Of course, the determination is not limited thereto, for example in the UE originally assigned to the different cluster and re-clustered clusters, the cluster within the same UE may reuse the same physical transmission resource.
[0048]
Since the user equipment when the cluster is divided in advance based on geographic location, so in the cluster based on the user equipment whether the user equipment belongs reusable Analyzing the same physical transmission resources, consider affect its geographic location, which can reduce interference . Further, when considering a uniform distribution of both cellular and D2D user equipment UE, can improve resource use efficiency, while reducing the interference.
[0049]
In one example, the resource allocation schedule includes physical resource block, one or more scheduling units 101 scheduled to the user equipment at least partially in the plurality of user equipment the same physical resource block, and a signaling generating unit 102 is further configured to reuse the same physical resource block of the same user equipment generates downlink control information and mapped to the same physical downlink control channel PDCCH resources. Here, the physical resource block is, for example, the LTE system frequency resource blocks.
[0050]
As described above, for example, one or more scheduling units 101 may be the same physical resource blocks scheduled to the user equipment is located in a different user units in the cluster. The signaling generating unit 102 to generate a user equipment and downlink control information is mapped onto the same PDCCH resources, wherein the user devices may include cellular D2D user equipment and user equipment.
[0051]
As one example, signaling generating unit 102 may also be configured to reuse the same physical resource blocks D2D user equipment to configure the same DP-RNTI, and scrambling the DP-RNTI using the downlink control information (scramble By) . For example, signaling generating unit 102 is sharing said plurality of physical resource blocks D2D user equipment generates a common DCI, DP-RNTI using the process of the DCI is scrambled cyclic redundancy check code (the CRC), and using PDCCH the DCI carries D2D transmission to the respective user equipment, thus saving the channel resources PDCCH.
[0052]
Wherein, in the user equipment and the presence of cellular D2D user equipment the same C-RNTI of the user equipment cellular case where multiplexing resource blocks, signaling generating unit 102 is configured DP-RNTI. Thus, the cellular user equipment and D2D user equipment may share, for example, the PDCCH control channel information (the DCI), which includes the allocated resource scheduling resource block information. Further, DCI may further include power control information (TPC information, for example), MCS programs. FIG. FIG. 3 shows the PDCCH comparison with the conventional case using the PDCCH configuration, it can be seen, compared with the conventional case, this arrangement saves channel resources PDCCH.
[0053]
In another example, even in the presence of the cellular user equipment and the user equipment D2D case where multiplexing resource blocks, signaling generating unit 102 may be configured to DP-RNTI assigned to a cellular user equipment before the C-RNTI is not the same value, and a plurality of user equipments to the common D2D same DP-RNTI, so that the cellular user equipment reads D2D user equipment and a plurality of different DCI DCI D2D user equipment to read the same. For example, a cellular user equipment and the user equipment D2D resource blocks allocated on the same, but power control information, the MCS and the like are different. 4, it can be seen, even such a configuration, compared with the conventional case can save channel resources PDCCH.
[0054]
Further, as shown in the dashed box 1, apparatus 100 may further comprise: a transceiver unit 103, configured to DP-RNTI of the user equipment transmits configuration instructions for the user equipment to said portion.
[0055]
As one example, signaling generating unit 102 is further configured to generate a RRC signaling comprising a respective user equipment, the RRC signaling comprising instructions arranged DP-RNTI for the user equipment. The transceiver unit 103 is configured to DP-RNTI of instructions to configure to the user equipment via RRC signaling.
[0056]
In addition, signaling may be used to carry instructions that DP-RNTI, and accordingly, the transceiver unit 103 can also send instructions to the DP-RNTI of the user equipment by other means. For example, by MAC CE (control element, the control information bits) to transmit the DP-RNTI instruction, wherein, may define a new MAC CE: DP-RNTI MAC CE. In addition to semi-static manner RRC, MAC signaling, the PDCCH may also be dynamically such DP-RNTI transmitted by the last PDCCH. Alternatively, the transceiver unit 103 may also be notified through a broadcast DP-RNTI, when the broadcast information included in each user ID and a corresponding device DP-RNTI.
[0057]
When a predetermined change in location of the user equipment (i.e., the D2D user equipment) generating apparatus 100 can reassign DP-RNTI. For example, when a change in position of the user equipment exceeds a geographic area where the user equipment to its original cluster corresponding to the time, signaling generating unit 102 generates a command for the user equipment to the new configuration of the DP-RNTI, and the transceiver unit 103 transmits the command to the user equipment a new pair. In addition, one or more scheduling unit 101 performs resource scheduling according to the new DP-RNTI.
[0058]
In addition, the transceiver unit 103 may be further configured control information to the plurality of user equipment to receive a downlink physical transmission resource requests from a plurality of users and devices.
[0059]
For example, the transceiving unit 103 may receive scheduling requests (Scheduling Request) PUCCH or a random access request in the PRACH. Then, one or more scheduling unit 101 receives a request from the user equipment scheduling the corresponding physical transmission resources, signaling generating unit 102 correspondingly generates downlink control information, and the transceiver unit 103 transmits the control information to said user equipment .
[0060]
In addition, the transceiver unit 103 may also receive location information reported by the user equipment. Alternatively, the transceiver unit 103 transmits a detection signal to the user equipment, e.g. PRS PRS signal, and receives a feedback signal from the user equipment, to determine the location of the user equipment. For example, one or more scheduling units 102 using the position information to the user equipment determines the cluster user equipment belongs, thereby further determining whether or can be multiplexed in the same physical transmission resource.
[0061]
FIG 5 will be described according to an exemplary block diagram showing an embodiment of the present disclosure or more scheduling units 101 of the following drawings. 5, one or more scheduling unit 101 includes: a sorting module 1011, which is configured to receiving a request from a user equipment for communication priority sorted; user equipment list generation module 1012, is configured to generate expressed list of user equipment each user equipment can reuse the same physical transmission resources, wherein the user enter the user equipment device list in the order of priority; and allocation module 1013, configured to respective available physical transmission resources are allocated a user equipment to the user equipment a list of each of the generated.
[0062]
For example, in one transmission interval (e.g., a subframe), there D2D transmission request resources to the user equipment device 100 and a cellular user equipment, the user sorting module 1011 pairs of these devices according to their traffic priority (e.g. determined according to QoS requirements priority) order. User equipment list generation module 1012 generates a list of user equipment, each user equipment in a list of user equipment can reuse the same physical transmission resources, wherein, in descending order of priority in the user enter the user equipment device list. For example, a user may generate a list of devices is equal to or smaller number of transmission resources and the available physical. Accordingly, the user equipment allocation module 1013 to assign a respective available physical transmission resources to each user device list.
[0063]
The following Example described the following criteria is given an example of operation of the respective modules: a user equipment located in the same cluster in a user apparatus using a physical transmission resources orthogonal to each other, but in different clusters user equipment (hereinafter simply referred to as cluster user equipment) can be multiplexed in the same physical transmission resource.
[0064]
For example, as shown in FIG 6, it is assumed there are 12 clusters in Figure 6 list the requesting user equipment in each cluster, and ordering module 1011 are arranged from top to bottom in descending order of priority of communication.
[0065]
User equipment list generation module 1012 generates a list of devices, for example, by a user operation. Specifically, first fill in the table DUE-P1, since DUE-P1 and DUE-P2 in different clusters, they can be added to the table DUE-P2, similarly, DUE-P3, ......, DUE- P12 may also be added to the table, thereby generating a list of the user equipment 7 shown in FIG. It should be understood that this is merely one example, operating a user equipment list generation module 1012 is not limited thereto, and may be performed to generate a list of user equipment based on other or additional criteria.
[0066]
When the timer overflows and 1014, the timer 1014 generates a list of user equipment, for each of which a set of available physical transmission resources,: Further, as shown in phantom in FIG. 5, one or more scheduling unit 101 may further comprise stop module 1012 corresponding to a user device list is generated, the allocation module 1013 available physical transmission resources allocated to the user equipment list corresponding to the user equipment. 1014 is to set the timer time judging means 100 waits for and limited to further speed up the response. Wherein, for different available physical transmission resources, different timers can be set.
[0067]
In summary, apparatus 100 according to this embodiment by dividing the user equipment based on the D2D cluster to the user equipment and a cellular user equipment uniform distribution of physical transmission resources, at least one of the following: to reduce interference and improve resource utilization efficiency and save channel resources PDCCH.
[0068]

[0069]
Figure 8 shows a block diagram, means for wireless communication according to another embodiment of the present disclosure includes, in addition 200 of the respective units 200 shown in FIG. 1 in addition, further comprising: a dividing unit 201, configured to the service coverage of the user equipment by the base station antenna is divided into several location areas, each of the user equipment and a user area as a cluster device.
[0070]
Due to the high probability of geographically closest mutual interference occurs between the user device and therefore to classify the user equipment to the same cluster, and that one or more, for example, the scheduling unit 101 for scheduling physical transmission resource different from each other, thereby reducing the occurrence of interference, improving communication quality.
[0071]
In one example, the division unit 201 is configured to the base station antenna is located at the center, according to the radial length of the coverage into one or more rings, and each ring are angularly divided into a certain angle several area. In other words, based on the division unit 201 divides L & θ coverage criteria. 9, the coverage area is divided into inner and outer rings, inner radial length (i.e., radius) L . 1 , the outer ring of the radial length L 2 , [theta] . 1 = [theta] 2 , i.e. both the inner and outer rings are divided into 360 / parts θ, each block is a cluster area. For example, by adjusting L . 1 , L 2 , θ size adjusting at least one cluster region, preferably, the adjustment L . 1 and L 2 . In addition, although FIG. 9 shows [theta] . 1 = [theta] 2 case, it may be a different value according to the actual needs of every [theta] is taken.
[0072]
The requirements of the actual application scenario, may take different values ​​of θ, the coverage area is divided into different numbers of clusters. Preferably, θ∈ [36 °, 90 °], dividing the number of clusters thus obtained between 8-20. Center of gravity of two adjacent sectors illustratively, obtained by dividing a value greater than the distance between the two pairs DUE-P resource reuse the same distance is preferably, for example, the distance can be guaranteed that they interfere with each other is controlled below a threshold . As can be seen, the greater the value of θ, the less the number of the divided clusters, the fewer user equipment reuse the same resources between different clusters, the smaller the interference. Conversely, the smaller the value of [theta], the more the number of the divided clusters, the more user equipment reuse the same resource, the system will improve performance. Thus, if the user equipment application scenario large number and hope to achieve higher efficiency of resource use, then the value of θ can be made as small as possible; user equipment if the application scenario small number, size and less sensitive to interference, so that it can θ value as large as possible. An example of this in FIG 9, assuming that θ = 60 °, was divided into 12 clusters, will be described as an example.
[0073]
Such areas may be divided into the following cases: a portion DUE-P DUE at two different clusters, as shown in FIG. For example, there is a DUE-P DUE respectively in the two clusters and cluster 3 9. Such that one or more scheduling unit 101 determines the hard DUE-P belongs to which cluster. In this case, you can independently be selected available physical transmission resources by the DUE, a further determination may be performed to divide it into a one cluster.
[0074]
In one example, where two user devices are located D2D D2D user equipment in different regions of the case of more than a predetermined number, the division unit 201 is further configured to adjust the radial length of each ring to adjust the area division, to reducing the number of user equipments which are located at two D2D D2D user equipment in different regions. In other words, by adjusting the area division are positioned to minimize the user equipment to a different area of ​​the D2D number.
[0075]
May also be provided a second timer (not shown), the overflow exceeds a predetermined value at the time to perform the adjustment, the adjustment to interrupt. Two physical transmission resources remain D2D user equipment D2D user equipment are located at different regions on, the D2D user equipment available to choose If after the above adjustment.
[0076]
In another example, one or more of the scheduling unit 101 is further configured to: two D2D D2D user equipment or user equipment case where the cellular user equipment located in two different regions, based on the two further user D2D the distance between the D2D user equipment or the distance between the device and the cellular user equipment to determine whether both may reuse the same physical transmission resource.
[0077]
Specifically, for example, in the case where the distance is less than a predetermined threshold value, one or more scheduling unit 101 determines that the two D2D D2D user equipment or the user uses the resource block orthogonal to each other with a cellular user equipment. With this setting, to avoid strong interference may occur in the cluster boundary.
[0078]
6 as an example, the cluster is assumed in FIG 6 corresponds to FIG. 1-12 9 1-11 clusters, and treated with D i-j represents a distance between the i-th DUE-P and j-th DUE-P (two are in different clusters), by d h-k represents the distance between the h-th DUE-P and a k-th the CUE (both in different clusters), can be set separately the threshold value d Q and d Q , the d ij of > D Q in the case of determining the i-th DUE-P and j-th DUE-P can reuse the same physical transmission resource in D h-K > D Q in the case of determining the h-th DUE-P and you can reuse the same physical transmission resource between the k CUE.
[0079]
If the user based on the above criteria generating device list of the user equipment in FIG. 6, it can operate as follows. DUE-P1 first added to the table; then the D 1-2 and D Q are compared, if the D 1-2 > D Q , DUE-P2 will be added to the table; further comparison, if the D 1-3 > D Q and D 2-3 D Q and D 2-15 D Q , D 2-11 > D Q , D 15-11 > D Q , ..., D 9-11 > D Q but D 10-11 D Q , D 2-23 > D Q , D 15-23 > D Q , ..., D 9-23 of > D Q but D 10-23 D Q , D 2-11 > D Q , D 15-11 > D Q , ..., D 9-11 > D Q and D 10-11 > D Q , the DUE-P1, DUE-P2, DUE-P15, ..., DUE-P10 and CUE 11 can reuse the same physical transmission resource, to add CUE11 table; if D 1-12 > D Q , D 2-12 > D Q , D 15-12 > D Q , ..., D 10-12 > D Q and D 12-11 > D Q DUE-P12 will be added to the table, so that the user equipment list shown in FIG. 11 can be obtained.
[0080]
This procedure is repeated to generate a list of user equipment, the user equipment can obtain a plurality of lists, and the corresponding allocation module 1013 available physical transmission resources allocated to the user equipment a user device list. FIG 12 illustrates an exemplary final result of resource allocation, wherein, using the same fill pattern to represent the correspondence between the user equipment and allocated resources, e.g., the blank squares represent the list of user equipment 1 (i.e., 11 of FIG. user equipment a list of user devices), which is assigned a resource, and so on.
[0081]
It should be noted that, in this example, each user equipment in a list of most one CUE.
[0082]
In addition to determining the distance based on the one or more scheduling unit 101 may also be employed in the following manner it is determined whether a plurality of user equipment can reuse the same physical transmission resource: each of area division unit 201 obtains from the region of an edge in a symmetrical manner the area is reduced to a certain extent to obtain the rest of the central region and the edge region as a region, in two or D2D D2D user equipment to user equipment where the cellular user equipment is located in two different regions, if both in each the edge region of the region, it is determined that both the physical transmission resources orthogonal to each other.
[0083]
Areas such as shown in Figure 13, hatched regions are filled with the corresponding cluster of a central region, are filled without the edge region of the corresponding cluster, the hollow square represents DUE-P1, the solid square represents DUE-P2, gradient fill the square represents DUE-P3, the filled square represents the point DUE-P4, it can be seen, DUE-P1 in a central region of the cluster 1, DUE-P2 at the edge region tuft 1, DUE-P3 in the edge region tuft 8, DUE-P4 in the central region of the cluster 8, arranged the one or more scheduling units 101, DUE-P1 with DUE-P3, DUE-P4 reuse the same physical transmission resource in accordance with; DUE-P2 may be multiplexed with DUE-P4 by the same physical transmission resource, but DUE-P3 using only physical transmission resources orthogonal to each other.
[0084]
In another example, one or more scheduling unit 101 may also be employed in the following manner is determined whether a plurality of user equipment can reuse the same physical transmission resource: the area division unit 201 is divided to be obtained at the base station antenna is located along a center cis clockwise or counterclockwise rotated by a certain angle, in order to obtain the dummy area division, and, if the user equipment is located in accordance with the area division in different regions belonging to the same area in the dummy region division, which is determined using the user equipment physical transmission resources orthogonal to each other .
[0085]
FIG 14 shows a schematic example of the configuration, in this example, clockwise rotated by an angle [alpha], e.g., [alpha] is one-half of θ1.
