Embodiment
Under TDM multiplex mode, if allow any one sub-frame of uplink as D2D subframe, can may cause the interference to cellular communication.
Such as, the sub-frame of uplink of first after special subframe is configured to D2D subframe.Specify in the protocol, first subframe after special subframe is sub-frame of uplink, is D2D subframe by this sub-frame configuration, not only can produce interference to cellular communication, system also can be caused cannot to determine the TDD up-downgoing reference configuration of the PUCCH feedback of D2D UE.Wherein, the TDD up-downgoing reference configuration of PUCCH feedback is used for reception and the ACK/NACK feedback that D2D UE carries out cellular downlink data, and it is determined according to the TDD uplink-downlink configuration of the current use in community and D2D sub-frame configuration.Why introduce the TDD up-downgoing reference configuration of PUCCH feedback, because under TDM multiplex mode, if the D2D subframe of D2D UE is it need the subframe of cellular downlink data being carried out to ACK/NACK feedback, then that D2D transmission can be caused to transmit with the PUCCH of honeycomb conflicts.After introducing the TDD up-downgoing reference configuration of PUCCH feedback, D2D UE receives cellular downlink data according to the instruction of the TDD up-downgoing reference configuration of PUCCH feedback, and carry out the feedback of ACK/NACK information, due in the TDD up-downgoing reference configuration of PUCCH feedback, D2D subframe is as pseudo-descending sub frame, be not used in feeding back ACK/nack message, thus avoid D2D transmission transmit with the PUCCH of honeycomb conflict.
Again such as, by D2D sub-frame configuration between two sub-frame of uplink, because current D2D UE likely can be operated in RRC idle condition, so its timing adopted is likely descending timing reference, as shown in Figure 1, the UE being in RRC connection status that its D2D subframe may be transmitted next sub-frame of uplink produces the interference between subframe.
When in the network coverage that D2D UE is operated in TDD system, how to configure the D2D subframe of D2D UE, to avoid the problems referred to above to occur, also do not provide solution at present.The embodiment of the present invention proposes solution for this kind of situation.The D2D resource allocation proposal that the embodiment of the present invention provides, its main principle comprises: the sub-frame of uplink that subframe is numbered 2 can not be configured to D2D subframe, and D2D subframe is not between two sub-frame of uplink.
Before the embodiment of the present invention is described in detail, first the TDD uplink-downlink configuration defined in LTE TDD system is described.
As shown in table 1, LTE TDD system defines 7 kinds of uplink-downlink configuration.
Table 1
Wherein, D represents descending sub frame, and U represents sub-frame of uplink, and S represents special subframe.
Below in conjunction with accompanying drawing, the technical scheme that the embodiment of the present invention provides is described in detail.
Embodiments provide a kind of D2D resource allocation method, as shown in Figure 2, the method comprises:
Step 200, determine the TDD uplink-downlink configuration that this community uses and D2D resource distribution cycle.
Wherein, the TDD uplink-downlink configuration that this community uses can be any one the TDD uplink-downlink configuration in table 1, also can be other TDD uplink-downlink configuration.
Step 210, instruction according to this TDD uplink-downlink configuration, from last sub-frame of uplink of the D2D resource distribution frame in this D2D resource distribution cycle, configuration D2D subframe, wherein, first sub-frame of uplink of the D2D resource distribution frame in this D2D resource distribution cycle be not as D2D subframe.
Because D2D communicates the ascending resource of multiplexing cellular network, therefore, D2D subframe is configured from last sub-frame of uplink of the D2D resource distribution frame in this D2D resource distribution cycle, refer to, from last sub-frame of uplink of this D2D resource distribution frame, in the sub-frame of uplink in this D2D resource distribution frame, configure D2D subframe.The D2D sub-frame number of concrete configuration is determined according to practical situations, and the present invention is not construed as limiting.
The method that the embodiment of the present invention provides can but be not limited only to be realized by base station (such as eNB).
The technical scheme adopting the embodiment of the present invention to provide carries out the configuration of D2D subframe, because first sub-frame of uplink of the D2D resource distribution frame in the D2D resource distribution cycle be not as D2D subframe, D2D UE is made to be easy to determine the TDD up-downgoing reference configuration of PUCCH feedback.If D2D UE needs the transmission in support RRC free time (idle) situation, adopt the technical scheme that the embodiment of the present invention provides, due to last sub-frame of uplink from the D2D resource distribution frame in the described D2D resource distribution cycle, configuration D2D subframe, therefore can avoid because timing offset causes the situation of sub-inter-frame-interference.
In the embodiment of the present invention, if the up-downgoing change-over period of above-mentioned TDD uplink-downlink configuration is 5 milliseconds, the D2D resource distribution cycle can take field as the cycle, namely 5 milliseconds, also can take radio frames as the cycle, i.e. the integral multiple of 10 milliseconds, such as 10 milliseconds, 20 milliseconds etc.If the up-downgoing change-over period of above-mentioned TDD uplink-downlink configuration is 10 milliseconds, the D2D resource distribution cycle can take radio frames as the cycle, i.e. the integral multiple of 10 milliseconds, such as 10 milliseconds, 20 milliseconds etc.
Below respectively for the up-downgoing change-over period of different TDD uplink-downlink configuration and D2D resource distribution cycle, the specific implementation of D2D sub-frame configuration is described in detail.
Preferably, if the up-downgoing change-over period of above-mentioned TDD uplink-downlink configuration is 5 milliseconds, and the above-mentioned D2D resource distribution cycle is 5 milliseconds, and so, the D2D resource distribution frame in the D2D resource distribution cycle is the field in a radio frames.The specific implementation of step 210 can but be not limited only to be: according to the instruction of this TDD uplink-downlink configuration, from last sub-frame of uplink of the field in this D2D resource distribution cycle, configuration D2D subframe, wherein, first sub-frame of uplink of the field in this D2D resource distribution cycle be not as D2D subframe.That is, D2D subframe can not be configured in the sub-frame of uplink that subframe label is 2 and 6.
Due in TDD uplink-downlink configuration 2, subframe 2 and subframe 6 is only had to be sub-frame of uplink.Therefore, when the TDD uplink-downlink configuration determining that community uses is 2, avoid D2D resource distribution period assignment is 5 milliseconds as far as possible.If the D2D resource distribution cycle is 5 milliseconds, then do not configure D2D subframe.
Concrete, if configuration 1 D2D subframe, last sub-frame of uplink of the field in the above-mentioned D2D resource distribution cycle can be configured to D2D subframe.
If configure at least 2 D2D subframes, can from last sub-frame of uplink of the field in this D2D resource distribution cycle, arranged in order D2D subframe forward.
Arranged in order D2D subframe forward, refers in the field in this D2D resource distribution cycle, according to the descending of subframe numbering, configures D2D subframe successively on sub-frame of uplink.
If the up-downgoing change-over period of above-mentioned TDD uplink-downlink configuration is 5 milliseconds, and the above-mentioned D2D resource distribution cycle be 5 milliseconds, for the TDD uplink-downlink configuration in table 1, the configuration of D2D subframe can be carried out in TDD uplink-downlink configuration 0 and 1.
For TDD uplink-downlink configuration 0, the configuration of 1 or 2 D2D subframe can be supported in 5 milliseconds of D2D resource distribution cycles.As shown in Figure 3, if configure 1 D2D subframe in 5 milliseconds of D2D resource distribution cycles, then before a radio frames in field, the sub-frame of uplink that configuration subframe is numbered 4 is D2D subframe, in the rear field of a radio frames, the sub-frame of uplink that configuration subframe is numbered 9 is D2D subframe; The TDD up-downgoing reference configuration of the PUCCH feedback obtained after configuration D2D subframe is TDD uplink-downlink configuration 1.If configure 2 D2D subframes in 5 milliseconds of D2D resource distribution cycles, then before a radio frames in field, the sub-frame of uplink that configuration subframe is numbered 4 and 3 is D2D subframe, and in the rear field of a radio frames, the sub-frame of uplink that configuration subframe is numbered 9 and 8 is D2D subframe; The TDD up-downgoing reference configuration of the PUCCH feedback obtained after configuration D2D shake is TDD uplink-downlink configuration 2.In the embodiment of the present invention, the subframe in a radio frames is from 0 to 9 numbering.
For TDD uplink-downlink configuration 1, the configuration of 1 D2D subframe can be supported in 5 milliseconds of D2D resource distribution cycles.As shown in Figure 4, before a radio frames in field, the sub-frame of uplink that configuration subframe is numbered 3 is D2D subframe, and in the rear field of a radio frames, the sub-frame of uplink that configuration subframe is numbered 8 is D2D subframe; The TDD up-downgoing reference configuration of the PUCCH feedback obtained after configuration D2D shake is TDD uplink-downlink configuration 2.
Preferably, if the up-downgoing change-over period of above-mentioned TDD uplink-downlink configuration is 10 milliseconds, and the above-mentioned D2D resource distribution cycle is the integral multiple of 10 milliseconds, so, D2D resource distribution frame in the D2D resource distribution cycle is one of them radio frames, typically refers to first radio frames in the D2D resource distribution cycle.The specific implementation of step 210 can but be not limited only to be: according to the instruction of this TDD uplink-downlink configuration, from last sub-frame of uplink of a radio frames in this D2D resource distribution cycle, configuration D2D subframe, wherein, first sub-frame of uplink of this line frame in this D2D resource distribution cycle be not as D2D subframe.Namely D2D subframe can not be configured in the sub-frame of uplink that subframe label is 2.
Due in TDD uplink-downlink configuration 5, subframe 2 is only had to be sub-frame of uplink.Therefore, when the TDD uplink-downlink configuration determining that community uses is 5, avoid is the integral multiple of 10 milliseconds by D2D resource distribution period assignment as far as possible.If the D2D resource distribution cycle is the integral multiple of 10 milliseconds, then do not configure D2D subframe.
Concrete, if configuration 1 D2D subframe, last sub-frame of uplink of a radio frames in the above-mentioned D2D resource distribution cycle can be configured to D2D subframe.
If configure at least 2 D2D subframes, can from last sub-frame of uplink of a radio frames in this D2D resource distribution cycle, arranged in order D2D subframe forward.
Arranged in order D2D subframe forward, refers in the above-mentioned radio frames in this D2D resource distribution cycle, according to the descending of subframe numbering, configures D2D subframe successively on sub-frame of uplink.
If the up-downgoing change-over period of above-mentioned TDD uplink-downlink configuration is 10 milliseconds, and the above-mentioned D2D resource distribution cycle be 10 milliseconds, for the TDD uplink-downlink configuration in table 1, the configuration of D2D subframe can be carried out in TDD uplink-downlink configuration 3 and 4.
For TDD uplink-downlink configuration 3, the configuration of 1 or 2 D2D subframe can be supported in 10 milliseconds of D2D resource distribution cycles.As shown in Figure 5, if configure 1 D2D subframe in 10 milliseconds of D2D resource distribution cycles, then in a radio frame, configuration subframe is numbered the sub-frame of uplink of 4 is D2D subframe; The TDD up-downgoing reference configuration of the PUCCH feedback obtained after configuration D2D subframe is TDD uplink-downlink configuration 4.If configure 2 D2D subframes in 10 milliseconds of D2D resource distribution cycles, then in a radio frame, configuration subframe is numbered the sub-frame of uplink of 4 and 3 is D2D subframe; The TDD up-downgoing reference configuration of the PUCCH feedback obtained after configuration D2D shake is TDD uplink-downlink configuration 5.
For TDD uplink-downlink configuration 4, the configuration of 1 D2D subframe can be supported in 10 milliseconds of D2D resource distribution cycles.As shown in Figure 6, in a radio frame, configuration subframe is numbered the sub-frame of uplink of 3 is D2D subframe; The TDD up-downgoing reference configuration of the PUCCH feedback obtained after configuration D2D shake is TDD uplink-downlink configuration 5.
If the D2D resource distribution cycle is the integral multiple of 10 milliseconds, with reference to above-described embodiment, can repeat no more.
Preferably, if the up-downgoing change-over period of above-mentioned TDD uplink-downlink configuration is 5 milliseconds, and the above-mentioned D2D resource distribution cycle is the integral multiple of 10 milliseconds, the specific implementation of configuration D2D subframe can but be not limited only to be: configure D2D subframe in the sub-frame of uplink in a radio frames in this D2D resource distribution cycle, the TDD up-downgoing reference configuration that the Physical Uplink Control Channel (PUCCH) obtained after making to configure D2D subframe feeds back and the TDD uplink-downlink configuration that standard specifies closest.
