Description

Confirm/non-confirmation feedback information transmission method and device

Technical field

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

Background technology

Cellular communication system is owing to having realized multiplexing to limited frequency spectrum resource, thereby it is flourish that wireless communication technology has been obtained.In cellular system, as two subscriber equipment (User Equipment, referred to as UE) between have service needed when transmission, subscriber equipment 1(UE1) to subscriber equipment 2(UE2) business datum, can first by air interface (abbreviation is eated dishes without rice or wine), be transferred to base station 1, base station 1 by core net by this user data transmission to base station 2, base station 2 is transferred to above-mentioned business datum UE2 again by eating dishes without rice or wine.UE2 adopts similar handling process to the business data transmission of UE1.When UE1 and UE2 are positioned at same cellular cell, as shown in Figure 1, although base station 1 and base station 2 are same websites, yet a data transfer still can consume two parts of radio spectrum resources.

As can be seen here, if UE1 and UE2 are positioned at same community and at a distance of nearer, so above-mentioned cellular communication method is not obviously optimum communication mode.For example, and in fact, along with the variation of mobile communication business,, the application in wireless communication system such as social networks, E-Payment is more and more extensive, make closely the transmission of the business between user demand growing.Therefore, the communication pattern of D2D is subject to extensive concern day by day.So-called D2D communication, as shown in Figure 2, refers to that business datum forwards without base station, directly by source user equipment, by eating dishes without rice or wine, is transferred to target UE, and this communication pattern has the feature that is obviously different from conventional cellular systems communication pattern.For the user of short-range communication, radio spectrum resources has not only been saved in D2D transmission, and has reduced the transfer of data pressure of core net.D2D communication based on Cellular Networks is a kind of under the control of system, the new technique directly communicating between the terminal equipment of a plurality of support D2D functions, it can reduce system resource and take, increase frequency spectrum efficiency of cellular communication system, reduce terminal transmitting power consumption, and save to a great extent network operation cost.

In cellular communication, network side is after UE service data transmission, UE should be to network side feeding back ACK/NACK, wherein, for the ascending physical signal control channel PUCCH(Physical Uplink Control Channel of loading ACK/NACK) can be by the descending control information format DCI format(Downlink Control Infor mation format of corresponding downlink data transmission) control information unit, place CCE(Control Channel Element) the implicit indication of sequence number, or indicated by the semi-static configuration of high-level signaling.UE, according to the correctness that receives data, determines mapping ACK or nack message in distributed PUCCH resource, to network side, feeds back.In addition, the channel design of PUCCH makes the ACK/NACK of a plurality of UE can be multiplexing at identical Physical Resource Block PRB(Physical Resource Block) to upper, reach the effect that improves resource utilization.

In D2D communication, business datum is directly transmitted between D2D UE, therefore in cellular communication system, need to increase the support to D2D communication mode, increased the complexity of system, system need to have certain control and management to D2D communication, between D2D communication and cellular communication, coordinate to control, and the particularity of D2D communication causes the Control and Schedule method in legacy cellular communication cannot directly apply to D2D communication equipment.For the D-A/N(D2D ACK/NACK in D2D communication) feedback information, the resource distribution of legacy cellular net and transmission means are probably inapplicable, because communicating by letter, D2D can adopt the method for half centralized scheduling, be D2D transmitting terminal UE(TxUE) under the management and control of network side, can dispatch D2D receiving terminal UE(RxUE) transfer of data, in the schedule information of D2D communication, may not exist DCI CCE sequence number for the implicit indication of corresponding PUCCH resource, Rx UE cannot be according to the processing method of Cellular Networks to Tx UE feedback D-A/N.In addition, the structural design of PUCCH is more suitable for the demand of Cellular Networks, has larger resource multiplex space, and in D2D communication, because D-A/N only needs the feedback to Tx UE, can, not to network side notice, therefore can not consider the requirement of high reusing degree.Meanwhile, if use PUCCH resource bearing D-A/N also can take Cellular Networks resource, increase the burden of cellular network.

For the processing method for ACK/NACK in cellular network in correlation technique, can not be applied to D2D communication, cause the poor problem of reliability of D2D communication, not yet propose at present effective solution.
