In this embodiment, the network side includes one or more of the following entities: an evolved node b (eNB), a Relay Node (RN), a cell coordination entity (MCE), a Gateway (GW), a Mobility Management Equipment (MME), and an Evolved Universal Terrestrial Radio Access Network (EUTRAN) Operation Administration and Maintenance (OAM) manager, where the eNB is taken as a network side entity for example.
In the LTE system, the radio resources are divided into resources in units of radio frames in the time domain, each radio frame is 10ms and includes 10 subframes. Each subframe is 1ms and is divided into 2 slots of 0.5ms, and fig. 4 is a schematic structural diagram of an LTE system frame in the related art, as shown in fig. 4. When the system frame structure adopts the common cycleWhen a Prefix (Normal Cyclic Prefix, abbreviated as Normal CP), each subframe contains 14 Single-carrier Frequency Division Multiple Access (SC-FDMA) symbols or Orthogonal Frequency Division Multiplexing (OFDM) symbols, and is divided into 2 slots, each slot includes 7 symbols, and when a system frame structure adopts an Extended Cyclic Prefix (Extended Cyclic Prefix, abbreviated as Extended CP), each subframe contains 12 symbols, and each slot includes 6 symbols. In the frequency domain, resources are divided in units of subcarriers, each subcarrier containing 15kHz or 7.5kHz resources. According to the above division unit of time domain and frequency domain resources, the minimum unit of the eNB scheduling time frequency resources for the UE is RB (Resource Block), where RB is defined as 1 slot in time domain and is continuous in frequency domain
Sub-carriers in or out of>
As shown in fig. 5.
In LTE systems, short TTI resource structures have been defined so far. Different from the above-mentioned method using a subframe as a time domain minimum scheduling unit, a shorter time domain scheduling unit, that is, a short TTI is adopted in the system, and fig. 6 is a schematic diagram of a timing relationship of scheduling of an sPUSCH resource by an eNB of an LTE system through dci in the related art, as shown in fig. 6. Each subframe can be divided into 6 sttis, each sTTI contains 2 or 3 OFDM/SC-FDMA symbols, or each subframe is divided into 2 sttis, each sTTI contains 7 OFDM/SC-FDMA symbols, i.e. one slot is used as one sTTI. The shorter TTI structure can realize faster resource scheduling to adapt to the service with higher timeliness requirement.
In resource scheduling using a subframe as a time domain scheduling unit, an eNB transmits DCI to a UE on a PDCCH resource of a downlink subframe # n, where the DCI schedules a physical uplink shared channel PUSCH resource indicating a # n +4 subframe configured for the UE, the UE receives DCI indication information carried on the PDCCH resource, and determines to use the PUSCH resource on the # n +4 subframe for carrying transmission of information according to a timing relationship of the fixed # n subframe DCI scheduling indication # n +4 subframe PUSCH resource, as shown in fig. 7.
In resource scheduling using short TTI as a time domain scheduling unit, an eNB sends dci to a UE on an sPDCCH resource of DL short TTI # n, where the dci schedules an sps cch resource indicating # n + k short TTI configured for the UE, the UE receives dci indication information carried on the sPDCCH resource, and determines to use the sps cch resource on short TTI # n + k for carrying out information bearer transmission according to a timing relationship of the srdci scheduling indication short TTI # n + k sps sch resource of fixed short TTI # n, as shown in fig. 8.
In the related art V2X communication, available resources for V2X UEs are configured in a resource pool manner. The PSCCH resource pool and the PSSCH resource pool are divided into a PSCCH resource pool and a PSSCH resource pool and are respectively used for bearing Sidelink control information and data information, the PSCCH resource pool and the PSSCH resource pool comprise the same subframe in a time domain and indicate the same subframe in a bitmap mode. The multiple subframes contained in the PSCCH/PSCCH resource pool are subsets of Uplink subframe of the system, and the subframes in the PSCCH/PSCCH resource pool may be distributed discontinuously in the time domain, so that the subframes in the PSCCH/PSCCH resource pool may be arranged logically continuously with respect to the physical sequence number subframe index # M of each Uplink subframe, and the logically continuous subframe sequence number of each subframe in the resource pool, that is, logic subframe index # M, may be newly defined, and a relationship between the subframes and the index is shown in fig. 9. In the example of fig. 9, the subframe, e.g., subframe index # 2, corresponds to a logic subframe index of index # 0.
In the prior art, when DCI indicates a Sidelink resource, DCI is transmitted at a # n subframe, the Sidelink PSCCH/PSCCH resource correspondingly scheduled is located at a # n + k subframe, which is a subframe in a Sidelink resource pool. When the Sidelink resource adopts a short TTI structure, the eNB indicates the DCI scheduled by the Sidelink resource for the UE, and the time sequence relationship also needs to be determined so as to uniquely determine the indicated Sidelink short TTI resource. The present embodiment provides a method and an apparatus for Sidelink resource allocation to solve the above technical problem.
In the sildelink transmission, there is no transmission scheme adopting the LTE sTTI structure at present, and without loss of generality, the present embodiment is discussed based on the defined sTTI subframe structure (as shown in fig. 6) in the cellular communication.
The method comprises the following steps:
when the eNB sends the Silelk short TTI resource scheduling information through DCI in subframe # n, the scheduled Silelk short TTI resource is the kth short TTI after subframe # n, k is the minimum value which is more than or equal to M, and the indicated kth short TTI is the resource in the Silelk resource pool. The value of M is predefined by the system or indicated by the eNB through higher layer signaling or physical layer signaling.
Specific example 1:
when the system predefines M =4, after receiving DCI scheduling information of the eNB for the Sidelink short TTI at subframe # n, the UE determines the minimum value k meeting the condition according to the short TTI structure in the subframe in the Sidelink resource pool by taking subframe # n where the DCI is located as the reference, so that the kth short TTI after subframe # n is the resource in the Sidelink subframe, and k ≧ M.
As shown in fig. 10, the eNB indicates the Sidelink short TTI resource scheduling for the UE in the DCI, the PDCCH resource for transmitting the DCI is located in subframe # n, and the Sidelink resource pool includes subframes # n, # n +3, # n +4. The Sidelink subframe adopts a structure of 2 short TTIs per subframe, so that the Sidelink short TTI configured by the eNB for the UE is the sTTI # 4 in subframe # n +3, the condition k =5 is met at the moment, k is greater than M, and the corresponding sTTI is located in the Sidelink subframe. And the UE determines the configured Sidelink short TTI resource according to the DCI indication of the eNB and the time sequence relation between the subframe where the DCI indication information is located and the indicated Sidelink short TTI, and sends the Sidelink information on the indicated short TTI resource.
The second method comprises the following steps:
and when the eNB sends the Silelk short TTI scheduling information through the DCI in the subframe # n, the scheduled Silelk short TTI resource is the kth logic short TTI after the subframe # n. The logical short TTI refers to short TTI resources numbered in the Sidelink subframe according to a logical continuous sequence.
Specific example 2:
the eNB instructs the UE to set the scheduling timing of the Sidelink resource to be k =4 through an RRC message, and then after receiving DCI scheduling information of the eNB to the Sidelink short TTI at subframe # n, the UE determines the k-th logical sTTI after subframe # n as a configured resource according to the logically continuous short TTI sequence in the subframes in the Sidelink resource pool by taking the subframe # n where the DCI is located as a reference, and carries out bearer transmission of the Sidelink information by using the resource.
As shown in fig. 11, the eNB indicates the Sidelink short TTI resource scheduling for the UE in the DCI, the PDCCH resource for transmitting the DCI is located in subframe # n, and the Sidelink resource pool includes subframes # n, # n +3, # n +4. The sildelink subframe adopts a structure of 2 short TTIs per subframe, so that the sildelink short TTI configured by the eNB for the UE is the 4 th logical short TTI after the subframe # n, i.e., the logical s TTI # 3 in subframe # n +4. And the UE determines the configured Sidelink short TTI resource according to the DCI indication of the eNB and the time sequence relation between the subframe where the DCI indication information is located and the indicated Sidelink short TTI, and sends the Sidelink information on the indicated short TTI resource.

When the eNB sends the Sidelink short TTI resource scheduling information through the sDCI in the short TTI # n, the scheduled Sidelink short TTI resource is the kth short TTI after the short TTI # n, k is the minimum value which is more than or equal to M, and the indicated kth short TTI is the resource in the Sidelink resource pool.
Specific example 3:
the eNB indicates M =4 through physical layer signaling, and the eNB indicates the configured Sidelink short TTI resource for the UE through the sdir. After receiving the sDCI scheduling information of the eNB for the Sidelink short TTI at the DL short TTI # n, the UE determines the minimum value k meeting the conditions according to the short TTI structure in the resource pool of the Sidelink by taking the short TTI # n where the sDCI is located as the reference, so that the kth short TTI after the short TTI # n is the resource in the Sidelink subframe, and k is more than or equal to M.
As shown in fig. 12, the eNB indicates the Sidelink short TTI resource scheduling for the UE in the sdic, the eNB adopts a structure of 6 short TTIs per subframe on the DL subframe, the sPDCCH resource for transmitting the sdic is located in the short TTI # n, and the Sidelink resource pool includes subframes # n, # n +2, # n +4. The sildelink subframe adopts a structure of 2 short TTIs per subframe, so that the eNB configures the sildelink short TTI for the UE, that is, the sTTI # 3 in subframe # n +2, and at this time, the condition k =4,k = m is satisfied, and the corresponding sTTI is located in the sildelink subframe. And the UE determines the configured Sidelink short TTI resource according to the sDCI indication of the eNB and the time sequence relation between the short TTI where the sDCI indication information is located and the indicated Sidelink short TTI, and sends the Sidelink information on the indicated short TTI resource.
Method IV
And when the eNB sends the scheduling information of the Sidelink short TTI resource through the sDCI in the short TTI # n, the scheduled Sidelink short TTI resource is the kth logic short TTI after the short TTI # n. The logical short TTI refers to short TTI resources numbered in the Silelink subframe according to a logical continuous sequence.
Specific example 4:
when the system predefines the Sidelink resource scheduling timing k =6, after receiving the sddci scheduling information of the eNB for the Sidelink short TTI at DL short TTI # n, the UE determines the kth logic sTTI after short TTI # n as the configured resource according to the logically continuous short TTI sequence in the subframe in the Sidelink resource pool with the short TTI # n of the sdi as the reference, and uses the resource to perform bearer transmission of the Sidelink information.
As shown in fig. 13, the eNB indicates the Sidelink short TTI resource scheduling for the UE in the sdri, the eNB adopts a structure of 2 short TTIs per subframe on a DL subframe, the sPDCCH resource for transmitting the sdi is located in short TTI # n, and the Sidelink resource pool includes subframes # n +2, # n +3, # n +4. The sildelink subframe adopts a structure of 2 short TTIs per subframe, so that the sildelink short TTI configured by the eNB for the UE is the 6 th logical short TTI after the subframe # n, i.e., the logical s TTI # 5 in subframe # n +4. And the UE determines the configured Sidelink short TTI resource according to the sDCI indication of the eNB and the time sequence relation between the subframe where the sDCI indication information is located and the indicated Sidelink short TTI, and sends the Sidelink information on the indicated short TTI resource.
It should be noted that the sildelink tti resource determined by the UE according to the foregoing method may specifically include any one or more of PSCCH, sPSCCH, and sPSSCH resources. The sPSCCH is a dedicated channel for carrying a Sidelink control information in the Sidelink short TTI structure, and the sPSSCH is a channel for carrying a Sidelink data in the Sidelink short TTI structure.
