Abstract

The embodiment of the present invention discloses a method for multi-beam transmission of uplink signals, a terminal device and a network side device. The method includes: receiving RRC signaling, wherein the RRC signaling includes at least one SRS resource set , each SRS resource set in the at least one SRS resource set corresponds to at least one spatial correlation information. The embodiments of the present invention enable the terminal equipment to transmit uplink signals according to a plurality of spatial correlation information, thereby effectively improving the uplink transmission efficiency of the communication system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for multi-beam transmission of uplink signals, a terminal device and a network side device. Background technique [0002] The fifth-generation (5G) mobile communication system new air interface (NR, New Radio) introduces large-scale antenna technology, which can better support multi-user-multiple-input multiple-output (MU-MIMO, Multi-User Multiple-Input Multiple-Output ) antenna technology. In order to reduce the equipment cost and baseband processing complexity caused by large-scale antenna arrays, the digital-analog hybrid beamforming technology is used to achieve a rough match between the transmitted signal and the channel. [0003] However, in the digital-analog hybrid beamforming technology, there is still a lack of a scheme for transmitting uplink signals based on multiple beams, resulting in low uplink transmission efficiency of the communication system. Conte...
