Abstract

The embodiment of the present invention discloses a method for transmitting an uplink channel with multiple beams, a terminal device and a network side device. The method includes: receiving configuration information, wherein the configuration information includes multiple Uplink beam information; the plurality of uplink beam information has an association relationship with related parameters of the uplink channel. Embodiments of the present invention enable the terminal device to use multiple uplink beam information to transmit uplink channels according to the correlation between the multiple uplink beam information and the related parameters of the uplink channel, 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 uplink channel, terminal equipment and network side equipment. 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 schemes for transmitting uplink channels based on multi-beams, resulting in low uplink transmission efficiency of the communication system.
