Method and apparatus for improving multi-user multiplexing performance, device, and storage medium

An apparatus, comprising:

• at least one processor, and a non-transitory memory storing instructions for execution by the at least one processor;
• wherein, when executed, the instructions cause the apparatus to perform operations comprising:
• configuring base sequence identifiers for a plurality of terminals by using radio resource control (RRC) signaling, wherein there is no orthogonality between base sequences indicated by the base sequence identifiers of the plurality of terminals;
• performing sounding reference signal (SRS) detection on the plurality of terminals based on a quasi-orthogonal sequence, to obtain channel information for sending an SRS by each terminal;
• and
• performing channel prediction based on the channel information of each terminal, to obtain a channel prediction result of each terminal.

A non-transitory memory storage medium comprising computer-executable instructions that, when executed, cause a first radio access network node to perform operations comprising:

• configuring base sequence identifiers for a plurality of terminals by using radio resource control (RRC) signaling, wherein there is no orthogonality between base sequences indicated by the base sequence identifiers of the plurality of terminals;
• performing sounding reference signal (SRS) detection on the plurality of terminals based on a quasi-orthogonal sequence, to obtain channel information for sending an SRS by each terminal;
• and
• performing channel prediction based on the channel information of each terminal, to obtain a channel prediction result of each terminal.
