Abstract

The embodiment of the invention provides an uplink signal transmission method, a terminal and network side equipment. The method comprises the following steps that: the terminal identifies the signaltype of an uplink signal; And the terminal determines an uplink sending beam corresponding to an uplink channel carrying the signal of the signal type, and uses the uplink sending beam to send the uplink signal in the uplink channel. As the corresponding uplink sending beam can be selected according to the signal type of the uplink signal, beam forming can be applied to uplink transmission, and the uplink transmission performance can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to an uplink signal transmission method, terminal and network side equipment. Background technique [0002] In order to improve the performance of the communication system, in the 5G communication system, both the terminal and the network side equipment can support multiple antennas for data transmission. Among them, beamforming, such as digital beamforming and analog beamforming, can be applied to downlink transmission at present, and communication performance can be improved through beamforming in downlink transmission. However, for terminals that can transmit using multiple antennas, how to apply beamforming in uplink transmissions is currently unconfirmed. It can be seen that how to apply beamforming in uplink transmission is currently a technical problem that urgently needs to be solved.
