Confirmation/non-acknowledgement feedback information transmission method and device

Technical field

The present invention relates to the communications fields, in particular to a kind of confirmation/non-acknowledgement feedback information (Acknowledgement/Negative Acknowledgement, referred to as ACK/NACK) transmission method and device.

Background technique

Cellular communication system is due to realizing the multiplexing to limited spectrum resources, so that wireless communication technique obtains It flourishes.In the cellular system, when thering is business to need to pass between two user equipmenies (User Equipment, referred to as UE) When defeated, user equipment 1 (UE1) arrives the business datum of user equipment 2 (UE2), can be passed first by air interface (referred to as eating dishes without rice or wine) It is defeated by base station 1, base station 1 passes through core net for the user data transmission to base station 2, and above-mentioned business datum is passed through sky again by base station 2 Oral instructions are defeated by shown in (a) of UE2 as shown in figure 1.The business data transmission of UE2 to UE1 uses similar process flow.As UE1 and UE2 is located at the same cellular cell, primary although base station 1 and base station 2 are the same websites shown in (b) as shown in figure 1 Data transmission still can consume two parts of radio spectrum resources.

It can be seen that if UE1 and UE2 is located at same cell and at a distance of relatively close, above-mentioned cellular communication method Apparently not optimal communication mode.And in fact, with mobile communication business diversification, for example, social networks, electronics branch Pay it is equal in a wireless communication system using more and more extensive so that the business transmission demand between short distance user increasingly increases It is long.Therefore, the communication pattern of D2D is increasingly subject to extensive concern.So-called D2D communication, as shown in Fig. 2, refer to business datum without It crosses base station to be forwarded, air interface transmission is directly passed through to target UE by source user equipment, this communication pattern has bright The aobvious feature for being different from conventional cellular systems communication pattern.For the user of short-range communication, D2D transmission is not only saved Radio spectrum resources, and reduce the data transmission pressure of core net.D2D communication based on Cellular Networks is a kind of in system Under control, the new technique directly communicated between multiple terminal devices for supporting D2D function, it can reduce system money Source occupy, increase frequency spectrum efficiency of cellular communication system, reduce terminal transmission power consumption, and largely save network operation at This.

In cellular communications, after the lateral UE transmission services data of network, UE should be to network side feeding back ACK/NACK, wherein It can be with for loading ACK/NACK ascending physical signal control channel PUCCH (Physical Uplink Control Channel) By descending control information format DCI format (the Downlink Control Information of corresponding downlink data transmission Format information unit CCE (Control Channel Element) serial number implicit indication is controlled where), or is believed by high level Order is semi-statically configured instruction.UE according to receive data correctness, determine in the PUCCH resource distributed mapping ACK or Nack message is fed back to network side.In addition, the channel design of PUCCH is multiplexed the ACK/NACK of multiple UE identical Physical Resource Block PRB (Physical Resource Block) achievees the effect that improve resource utilization to upper.
