Abstract

The invention provides a method, a device and a system for processing a pseudo random sequence. The method comprises steps: a sending terminal configures and sends a random seed, wherein the random seed is used for generating a corresponding pseudo random sequence, and the pseudo random sequence is used for at least one of: data transmission resource allocation, and channel access resource allocation. Thus, the problem of low resource utilization in the case of channel access in the related art can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a pseudo-random sequence processing method, device and system. Background technique [0002] Due to the rapid growth of multimedia service demands, the shortage of spectrum resources has become a challenge for mobile communications. In the traditional cellular network, direct communication between users is not allowed. Although this centralized working method facilitates the management and control of resources and interference, the utilization rate of resources is low. [0003] In related technologies, research on channel access technology mainly focuses on wireless local area networks. For example: distributed medium access technology for wireless local area network, semi-random backoff method for realizing resource reservation in wireless local area network, etc. However, when the number of transmitted users increases, the collision probability will increase greatly, result...
