Problems solved by technology

[0002] The precoding of uplink transmission usually uses the precoding indicated by the serving node. The precoding is selected from the predefined codebook. This method needs to use wideband precoding and the precoding accuracy is low, and the performance improvement for uplink transmission is limited. In When there is complete reciprocity or partial reciprocity in the uplink and downlink channels, the terminal cannot obtain high-precision precoding based on downlink channel measurements
The existing technology has low precoding accuracy for uplink transmission signals, and cannot guarantee the accuracy and reliability of uplink transmission

[0037] In a time division duplexing (Time Division Duplexing, TDD) or frequency division duplexing (Frequency Division Duplexing, FDD) system, there may be complete reciprocity or partial reciprocity between uplink and downlink channels. Complete reciprocity means that the characteristics of the uplink channel can be obtained completely by the measurement of...

Abstract

The invention provides an uplink transmission method and device, a signal receiving method and device, a terminal, a service node and a medium. The uplink transmission method comprises the following steps: carrying out SRS beamforming on a sounding reference signal according to a target parameter, wherein the target parameter is determined according to downlink channel information; receiving precoding information; and sending an uplink transmission signal according to the target parameter and the precoding information.

Description

technical field [0001] The present application relates to a wireless communication network, for example, to an uplink transmission and signal receiving method, device, terminal, service node and medium. Background technique [0002] The precoding of uplink transmission usually uses the precoding indicated by the serving node. The precoding is selected from the predefined codebook. This method needs to use wideband precoding and the precoding accuracy is low, and the performance improvement for uplink transmission is limited. In When the uplink and downlink channels have complete reciprocity or partial reciprocity, the terminal cannot obtain high-precision precoding based on the downlink channel measurement. In the prior art, the precoding precision of the uplink transmission signal is low, and the precision and reliability of the uplink transmission cannot be guaranteed. Contents of the invention [0003] The present application provides an uplink transmission and signal ...
