Abstract

The invention discloses a code multiple-access method. The method comprises a step of selecting a codebook from a preset codebook set to encode a data stream based on non-orthogonal sparse encoding superposition technology when the data flow sent by user equipment is received, a step of obtaining a resource block corresponding to the user equipment according to the mapping relationship between the user equipment and the resource block in the codebook, and a step of transmitting the encoded data stream by using the resource block. The invention also discloses a code multiple-access device which comprises an encoding unit, a resource block obtaining unit and a transmission unit. According to the method and the device, the access capacity of a system can be increased exponentially, at the same time the multidimensional modulation and spread spectrum technology is used, and the link quality of a single user can be increased greatly.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a coded multiple access method and device. Background technique [0002] Machine to Machine Communication (M2M) or Machine Type Communication (MTC) is a communication method of Human to Human (H2H), which refers to a communication without human intervention . This type of communication can be used in a wide range of applications such as smart meters, vehicle tracking, vending machines, security monitoring, and many more. Efficient support for MTC communication is considered to be a key requirement for future 5G communication. [0003] In the 5G wireless communication system, the number of MTC far exceeds the number of traditional H2M, and the MTC service generally has the characteristics of small data services, which poses a severe challenge to the FDMA multiple access technology adopted by the current 4G system. The signaling process of FDMA multiple ac...
