Method, device and apparatus for selecting user signature vector, and storage medium

A device for selecting a user signature vector, comprising:

• a processor;
• and
• a transceiver, connected to the processor and configured to receive and transmit data under control of the processor;
• wherein the processor is configured to:
• acquire a measurement result of an actual channel state of a terminal;
• determine, based on the measurement result and a preset measurement threshold, a measurement result interval to which the measurement result belongs;
• determine, based on a preset correspondence between measurement result intervals and user signature vector sets, a candidate user signature vector set corresponding to the measurement result interval to which the measurement result belongs, wherein the candidate user signature vector set comprises one or more user signature vectors;
• and
• select the user signature vector from the candidate user signature vector set.

A non-volatile computer storage medium, which stores thereon computer readable instructions executable by a processor, wherein when executing the computer readable instructions, the processor performs following operations:

• acquiring a measurement result of an actual channel state of a terminal;
• determining, based on the measurement result and a preset measurement threshold, a measurement result interval to which the measurement result belongs;
• determining, based on a preset correspondence between measurement result intervals and user signature vector sets, a candidate user signature vector set corresponding to the measurement result interval to which the measurement result belongs, wherein the candidate user signature vector set comprises one or more user signature vectors;
• and
• selecting a user signature vector from the candidate user signature vector set.
