Embodiment 1

[0030] see figure 2 , the SCI format X is the first stage SCI, and the resource pool is the case a, then each subchannel on each time slot in the resource pool contains a PSCCH candidate; if there are remaining PRBs, only when the number of remaining PRBs When the frequency domain size of the PSCCH candidate is greater than or equal to, the PSCCH candidates are included in the remaining PRBs; the number of PSCCH candidates included in the remaining PRBs may be one or more.

Embodiment 2

[0032] Instead, see image 3 , the remaining PRBs do not contain PSCCH candidates;

Embodiment 3

[0034] see Figure 4 , the SCI format X is the first stage SCI, the resource pool is the case b, each time slot in the resource pool only includes PSCCH candidates in the remaining PRBs, and subchannels do not include PSCCH candidates, the remaining The number of PSCCH candidates included in the PRB may be one or more.

Abstract

The present invention proposes a method for triggering collaboration between UEs, including the following steps: receiving resource pool configuration information; if the resource pool configuration information includes SCI format X configuration information, UE-A monitors the resource pool in the resource pool. SCI format X; otherwise, end the process; the SCI format X contains the type indication of the resource set, and the type indication of the resource set is used to indicate the type of the resource set sent by UE-A; if UE-A monitors the SCI format X, it is considered that UE‑B requests cooperation between UEs; otherwise, the process is terminated. Compared with the prior art, a new SCI format is designed, which can dynamically and on-demand request cooperation between UEs, which can not only reduce the transmission delay of cooperation information between UEs, but also improve the effectiveness of cooperation information.

Description

technical field [0001] The present invention relates to the technical field of inter-UE cooperation, and in particular, to a triggering method for inter-UE cooperation. Background technique [0002] In 5G New Radio (NR), when user equipment (UE) transmits and receives data through sidelink (sidelink), there are two resource allocation modes (modes), one is by the base station Resource allocation is called mode 1, and one is autonomous resource selection by the UE (mode 2). When the sender UE works in mode 2, the traditional autonomous resource selection method consumes a lot of power, and the selected resource will be affected by the hidden node. For example, if the hidden node occupies the selected resource, it will lead to resource conflict. In addition, the traditional autonomous resource selection method will also be affected by factors such as continuous collision. Inter-UE cooperation is widely believed to improve the reliability of resource selection and reduce the ...
