Embodiment 1

[0221] This preferred embodiment provides a method for a D2D UE to transmit D-A / N. In this embodiment, the D2D sending UE (equivalent to the second D2D UE in the above embodiment) can receive the corresponding The D-A / N fed back by the D2D receiver UE (equivalent to the first D2D UE in the foregoing embodiment).

[0222] The method includes the following steps: the network side instructs a D2D receiving UE (Rx UE) and a D2D transmitting UE (Tx UE) about the D-A / N resource configuration of the Rx UE through high layer signaling configuration.

[0223] During implementation, the high-layer signaling may be a D2D configuration message (D2D Reconfiguration Message).

[0224] As a preferred implementation manner, the D-A / N resources configured by the network side are PRB resources, including one or more PRBs, and the allocated D-A / N resources are indicated by indicating PRB Index. Preferably, the PRBs configured by the network side and used as D-A / N resources are indicated in the ...

Embodiment 2

[0233] This preferred embodiment provides a method for D2D UE to transmit D-A / N. In this embodiment, the Rx UE (equivalent to the first D2D UE in the above embodiment) obtains the D-A / N configured by the network side through high-level signaling. resource, carrying the D2D data reception status feedback information (D-A / N) on the D-A / N resource and sending it to the Tx UE (equivalent to the second D2D UE in the foregoing embodiment).

[0234] During implementation, the high-layer signaling may be a D2D configuration message (D2D Reconfiguration Message).

[0235] As a preferred implementation manner, the D-A / N resources configured by the network side are PRB resources, including one or more PRBs, and the allocated D-A / N resources are indicated by indicating PRB Index.

[0236] In order to improve the efficiency of signaling bearer, the PRB configured by the network side as a D-A / N resource is indicated by a D2D configuration information element (D2DReconfiguration IE) in high-...

Embodiment 3

[0248] This preferred embodiment provides a method for D2D UE ACK / NACK information transmission, the method includes: the Tx UE (equivalent to the second D2D UE in the above embodiment) obtains information about the Rx UE ( It is equivalent to the D-A / N resource of the first D2D UE in the above embodiment, and the D2D data reception status feedback information sent by the Rx UE is received on the above D-A / N resource.

[0249] As a preferred implementation manner, the high-level signaling is a D2D configuration message (D2D ReconfigurationMessage).

[0250] As a preferred implementation manner, the D-A / N resources configured by the network side are PRB resources, including one or more PRBs, and the allocated D-A / N resources are indicated by indicating PRB Index.

[0251] Preferably, the PRB used as the D-A / N resource configured by the network side is indicated by a D2D configuration information element (D2DReconfiguration IE) in the high layer signaling.

[0252] As a preferr...

Abstract

The invention discloses a confirming / non-confirming feedback information transmission method and device. The method comprises the steps that D-A / N resources of first D2D UE are configured at a network side; and the network side transmits messages which comprise the D-A / N resource configuration information of the first D2D UE through high-layer signals, wherein the D-A / N resource configuration information indicates the D-A / N resources which are configured to the first D2D UE. According to the method and the device, effective transmission of feedback information in D2D communication is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for transmitting Acknowledgment / Negative Acknowledgment (ACK / NACK for short) feedback information. Background technique [0002] Because the cellular communication system realizes the multiplexing of limited spectrum resources, the wireless communication technology has been developed vigorously. In a cellular system, when there is a service to be transmitted between two user equipments (UE1), the service data from user equipment 1 (UE1) to user equipment 2 (UE2) will first pass through the air interface (referred to as UE). air interface) to base station 1, base station 1 transmits the user data to base station 2 through the core network, and base station 2 then transmits the above service data to UE2 through the air interface. figure 1 In (a) shown. The service data transmission from UE2 to UE1 adopts a similar processing flow. When UE1 and UE2 are locate...
