Abstract

The invention provides reference signal transmitting and processing methods, devices and a communication node. The transmitting method comprises steps: sequences used by reference signals of one or more ports are configured, wherein each port of the reference signals is corresponding to one sequence, and each sequence comprises a first subsequence and a second subsequence, the relationships amongmultiple sequences corresponding to the multiple ports comprise at least one selected from the following: being the same or orthogonal between first subsequences of multiple sequences corresponding tothe multiple ports, being opposite or orthogonal between second subsequences of multiple sequences corresponding to the multiple ports and being not orthogonal between multiple sequences corresponding to the multiple ports, and multiple sequences corresponding to the multiple ports use different pseudo-random sequences; and reference signals are transmitted to a first communication node on a portcorresponding to the configured sequence. Thus, the problem of how to reuse more users in the case of multiuser scheduling under different orthogonal sequence lengths in a related technology is solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular, to a method and device for sending and processing a reference signal, and a communication node. Background technique [0002] Currently, the physical layer technology of new radio (NR) is under intense discussion in 3GPP RAN1. More flexible and efficient has always been the goal of NR physical layer design. The utilization of high-frequency bands in NR is a major focus, and in order to compensate for the path loss of high-frequency bands, the multi-antenna beamforming scheme seems to be an indispensable solution. In the multi-antenna beamforming scheme, the base station uses multiple antennas to send out very narrow beams to obtain beamforming gain. In this way, if the transmissions of different users or different layers of the same user are relatively independent, the research on multi-user multiplexing becomes a major focus. [0003] The design of the demodulation...
