In D2D communication system, the D2D transmitting terminal UE having D2D data to be sent can obtain the physics limit link shared channels (PhysicalSidelinkSharedChannel of D2D communication from eNB, referred to as PSSCH) resource distribution, or in the predefined resource pool of system, select certain PSSCH resource to use, no matter how transmitting terminal UE obtains PSSCH resource, transmitting terminal UE needs to control indication information by D2D, also side chain road (i.e. D2D link) control information (SidelinkControlInformation can be called, referred to as SCI) the PSSCH resource used is indicated to receiving terminal UE, and other launch relevant control information to D2D data, as message control system (MessageControlSystem, referred to as MCS), UEID etc.In a D2D resource period, the physics limit link control channel (PhysicalSidelinkControlChannel at SCI place, referred to as PSCCH) channel resource divides in units of subframe subframe with the PSSCH resource of carrying D2D data, PSCCHsubframe carries D2D and controls indication information, PSSCHsubframe carries D2D data, as shown in Figure 4, PSSCHsubframe can refer to whole system uplink subframe, or the subframe in the PSSCH sub-frame resources pond of system predefine or configuration, or by time-domain resource pattern (TimeResourcePattern, referred to as TRP) subframe that indicates.Transmitting terminal UE carries the control indication information about PSSCH subframe in SCI, is used to indicate the relevant information of the D2Ddata transmitted in one-period, comprises PSSCH configuration, MCS etc.Transmitting terminal UE indicates the configuration of corresponding D2D data resource by SCI to one or more receiving terminal UE, make receiving terminal UE after receiving control indication information, the instruction of PSSCH subframe can be obtained, and on corresponding channel resource, receive required data according to instruction.
The PSSCH of transmitting terminal UE in one-period can transmit one or more MACPDU, and namely transmitted MACPDU quantity Q is more than or equal to 1.The defining method of the value of quantity Q can have following three kinds:
Method one
Q value is indicated to transmitting terminal UE by eNB:
When the PSSCH resource that transmitting terminal UE uses configures instruction by eNB, eNB can also configure the MACPDU quantity that the PSSCH subframe of instruction transmitting terminal UE within the cycle is transmitted further, for further accurate adjustment control D2D resource distribution.
Wherein, eNB can indicate transmitting terminal UE about the configuration of Q value by high-level signaling and/or physical layer signaling.
When Q is indicated by high-level signaling or physical layer signaling, the Q value indicated by eNB is unique numeric, and transmitting terminal UE transmits Q MACPDU within the cycle;
When Q is indicated by high-level signaling and physical layer signaling, eNB indicates one or more described Q value by high-level signaling, namely one group of Q value list is indicated, and in Q value list, indicate an actual Q value used further by physical layer signaling, the Q value that transmitting terminal UE indicates with final physical layer, transmits Q MACPDU within the cycle.

Method two
Q value oneself is determined by transmitting terminal UE:
When transmitting terminal UE selects PSSCH subframe voluntarily for transmitting D2DMACPDU in D2D resource pool, or eNB indicates configured PSSCH sub-frame resources to transmitting terminal UE, but when not indicating corresponding Q value, transmitting terminal UE oneself can determine Q value, and PSSCH subframe within the cycle transmits Q MACPDU, reach the object meeting own data transmission demand.
Wherein, when transmitting terminal UE determines Q value, this Q value can be determined based on the one or more of following factors: the data volume to be sent, D2D ChannelMeasurementReport DETAILED etc. of the PSSCH sub-frame number in the cycle, the number of transmissions of each MACPDU, transmitting terminal UE.

Method three
Q value is jointly determined by eNB and transmitting terminal UE:
ENB sends a reference value Q of MACPDU by high-level signaling or physical layer signaling instruction transmitting terminal UE 0, transmitting terminal UE determines the MACPDU quantity Q of actual transmission further voluntarily, and Q≤Q 0.
ENB indicates Q by high-level signaling 0during value, system information block SIB (SystemInformationBlock, also referred to as system broadcast message) can be adopted to indicate, the Q now indicated in SIB 0value is cell-level parameter, and in Ji Dui community, all D2DUE are unified effective, or further, SIB can carry out Q according to different D2DUEgroup 0value configuration, then configure the Q of instruction 0value is all unified effective for the UE belonging to corresponding D2Dgroup.
ENB indicates Q by high-level signaling 0during value, radio resource control RRC (RadioResourceControl) message can also be adopted to indicate, RRC information is UE level configuration indication information, independently can carry out Q for each UE 0the configuration instruction of value, indicated Q 0value is only effective to the transmitting terminal UE receiving this RRC information.Further, for configuring instruction Q 0the RRC information of value is D2D communication specialized configuration Indication message D2DReconfiguration.
ENB indicates Q by physical layer signaling 0during value, D2D private downlink control information form DCIformat5 can be adopted to indicate, indicate by the corresponding instruction bit position in D2DDCI the Q configured to transmitting terminal UE 0value.
Wherein, the Q that configures based on eNB of transmitting terminal UE 0value, determines the MACPDU quantity Q of actual transmission, and PSSCH subframe within the cycle transmits Q MACPDU, reaches the object meeting own data transmission demand.
When transmitting terminal UE determines Q value, Q value can be determined: the data volume to be sent, D2D ChannelMeasurementReport DETAILED etc. of the PSSCH sub-frame number in the cycle, the number of transmissions of each MACPDU, transmitting terminal UE based on the one or more of following factors, wherein, the Q value that transmitting terminal UE determines can not more than the reference value Q of eNB configuration 0, i.e. Q≤Q 0.
