Title:
RETRANSMISSION-BASED MULTI-USER SUPERPOSITION TRANSMISSION METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/008211
Kind Code:
A1
Abstract:
Provided are a retransmission-based multi-user superposition transmission method, device and system. The method comprises: a base station sends retransmission configuration information or retransmission configuration information and modulation mode information about a second UE using the retransmission technique to a first UE that is paired with the second UE to perform MUST transmission, so that the first UE detects data of the second UE according to the retransmission configuration information or the retransmission configuration information and the modulation mode information about the second UE and performs interference cancellation so as to obtain data of the first UE itself. By means of the embodiments of the present invention, unnecessary signalling overheads and repetitive detection operations are avoided, so that the performance and efficiency of MUST transmission are improved.
