Abstract

Systems and methods are provided to achieve data scrambling and transmission identification in the SL for UE cooperation (UC), in which one or more cooperating UEs help with a transmission to a target UE. Corresponding configuration schemes are also provided. In addition, systems and methods are provided to achieve data DMRS sequence generation and transmission identification in SL for UC, in which one or more cooperating UEs help with a transmission to a target UE. Corresponding configuration schemes are also provided. Furthermore, systems and methods of SL control channel scrambling and identification for UE cooperation are provided.

Claims22

Dependent claims

A method in a UE comprising acting as a cooperating UE (CUE) to assist at least one target UE (TUE) by:

receiving a signal from a base station carrying a first modulated scrambled data block;
demodulating, de-scrambling and decoding the first modulated scrambled data block to produce a decoded data block;
determining that the decoded data block is for said at least one TUE;
encoding the decoded data block to produce an encoded data block, and scrambling the encoded data block based on at least a group identifier (ID) to produce a scrambled data block;
modulating the scrambled data block to produce a second modulated scrambled data block;
transmitting the second modulated scrambled data block for reception by the at least one TUE.
