Group Communication Apparatus and Method and Communication System

Abstract

This disclosure provides a group communication apparatus and method and a communication system. The group communication method includes: scrambling data information of a message by using corresponding scrambling information according to a message type and/or a message transmission range; wherein, different message types and/or message transmission ranges correspond to different scrambling information. Therefore, internal members or peripheral devices of a group may selectively receive messages of different types or different target ranges. Hence, not only messages may be ensured to be accurately received by corresponding receivers, but also security of internal message may be improved.

What is claimed is: 
     
         1 . A user equipment (UE), comprising:
 a memory that stores a plurality of instructions; and   a processor coupled to the memory and configured to execute the instructions to:   transmit sidelink control information (SCI) to another UE, wherein the SCI comprises:   identification information of the UE,   identification information of a group, and   indication information used for indicating message transmission scope; and   transmit data information associated with the SCI to the another UE.
