The invention discloses a method and device for configuring and determining a multi-user coding mode based on coding superposition, which is used to solve the problem that in SCMA access technology, it is not easy for multiple users because the coding modes corresponding to different users have equal diversity degrees. The problem of detection performance improvement. The configuration method includes: the network device determines the user equipment that multiplexes the same transmission resource; the network device configures a different column for each of the user equipment from the pre-configured coding matrix formed by multi-user coding superposition, so that each of the The user equipment performs data transmission according to a coding manner corresponding to a column configured by the network device, where at least two columns in the coding matrix have unequal diversity degrees. Since the columns configured by the network device for the user equipments that multiplex the same transmission resources from the encoding matrix may have reasonably inconsistent diversity degrees, it is easy to improve the performance of multi-user detection.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for configuring and determining a multi-user coding mode based on coding superposition. Background technique [0002] Mobile communication needs to make all users share limited wireless resources, so as to achieve the purpose of simultaneous communication of different users and different locations and minimize interference. This is the multiple access technology. With the rapid development of wireless communication, the number of users and business volume are increasing explosively, which constantly puts higher requirements on the system capacity of wireless networks. Explosive user growth makes multiple access technology a central issue in network upgrades. Multiple access technology determines the basic capacity of the network and has a great impact on system complexity and deployment cost. [0003] The traditional mobile communication syste...
