Abstract

The present disclosure relates to a method and device for multi-user overlay transmission (MUST), especially a communication method for multi-user overlay transmission implemented at network devices and terminal devices based on DMRS transmission, as well as network devices and terminal devices. By using a signaling scheme in which only the DMRS port and scrambling code identifier of the paired terminal device is sent to the target terminal device, a large number of possible pairing choices corresponding to all possible configurations of the target terminal device are avoided and significantly reduced Signaling overhead during transmission.

Description

technical field [0001] Embodiments of the present disclosure generally relate to wireless communication technologies, and more specifically, to a communication method based on DMRS transmission, Multi-User Superimposition Transmission (MUST) implemented at network devices and terminal devices, and network devices and terminal devices. Background technique [0002] Currently, for the Long Term Evolution (LTE) system, a Downlink (DL) Multi-User Superposition Transmission (MUST) technology has been proposed. With this technique, intra-cell multi-user superimposed transmission on e.g. Physical Downlink Shared Channel (PDSCH) can be realized in LTE systems with assistance information from the serving base station to user equipments about their interference in the cell . For DL ​​MUST, the 3rd Generation Partnership Project (3GPP) standardization organization has proposed the following three implementations: (1) use the same transmission scheme and the same spatial precoding vect...
