The first packet that calling UE sends is received, first packet can be user data information, also may be used
Being control information.Specifically, physical side link control channel (Physical Sidelink can be passed through
Control Channel, PSCCH) receive, it is also possible to by physical side link shared channels (Physical
Sidelink Shared Channel, PSSCH) receive.
103rd, called UE sends response message to calling UE.
Called UE is examined to first packet after the first packet for receiving calling UE transmission
Mistake, if receiving correct, returns to calling UE and confirms response ACK (Acknowledgement) message,
To notify that calling UE continues to send the second packet；If error detection is not just finding the first packet for receiving
Really, then negative response NACK (negative acknowledge) message is sent to calling UE, to notify
Calling UE retransmits the first packet.
In the embodiment of the present invention, called UE is set up DMO with calling UE and is communicated, and called UE receives master
The first packet for making UE send, afterwards, called UE sends response message to calling UE, and response disappears
Breath includes ACK or NACK message, and wherein ACK message represents the first data that called UE is received
Bag is errorless, indicates that called UE sends the second packet, NACK message represent that called UE receives the
One packet is incorrect, indicates that called UE retransmits the first packet.Therefore ACK/NACK machines are passed through

Person increases a domain and is exclusively used in feeding back ACK and NACK.
When being fed back by PSSCH, can punch and be fed back in being placed on PSSCH.
Specifically, called UE selects PSCCH or PSSCH by sending data moment preferential principle
Loading ACK or NACK message, concrete mode are as follows：
Called UE judges whether to send number earlier than by PSSCH by the moment of PSCCH transmission data
According to moment, if earlier than the destination channel that, it is determined that PSCCH is loading ACK or NACK message,
If being later than, it is determined that PSSCH is the destination channel of loading ACK or NACK message.
Further, as another embodiment, in order to prevent missing ACK/NACK receiving times, such as
Fruit is based on class Routing Protocol, and each node both knows about mutual transmission resource table configuration, then can be when specified
Receive in frequency resource, to improve efficiency.Specifically resource allocation request is：
Because system can not be same in same time slot for time division duplex (Time Division Duplexing, TDD)
When receive and dispatch, if two UE are sent simultaneously, the information of other side cannot be received each other.Accordingly,
Individual calling communication is carried out between the two UE, then ACK/NACK will be unable to be successfully received, so necessary
Stagger in resource distribution.In order that ACK/NACK message can be fed back in certain time interval T,
Ensure each UE at least 2 times send opportunity in the time T, it is impossible to two UE occur in time T
Interior this several times launching opportunity all in same time slot.When number of users is more, each time slot can be put many
Individual user, to ensure user is evenly distributed in time T, so as to ensure that ACK/NACK is obtained in time
Feedback.
Time-domain resource configuration can be pre-configured, or by calling UE and called UE oneself by upper strata
Random selection time-domain resource, is distributing time-domain resource to called UE according to above-mentioned resource allocation request
Afterwards, called UE obtains the N number of time slot for sending ACK/NACK in preset time T to calling UE,
N is more than 2 (i.e. at least 2 time slots), when called UE takes the one of free time in N number of time slot again
Gap sends ACK/NACK to calling UE.
For example：In order that ACK/NACK was fed back within the time of time T=100ms, in 100ms
In, the time-domain resource to UE1 distribution is 2ms and 50ms, and 2ms is allocated to UE2 simultaneously,
So, when UE1 occurs resource contention in 2ms and UE2, can continue to retransmit in 50ms,
So must assure that in 100ms, UE1 can take a free timeslot transmission ACK/NACK and disappear
Breath.
