Problems solved by technology

[0002] At present, the base station configures a sounding reference signal (Sounding Reference Signal, SRS) resource set for the terminal, and the uplink transmission beam is semi-statically configured for each SRS resource or for an SRS resource set. When it is necessary to change the uplink transmission beam of an SRS resource When , radio resource control (Radio Resource Control, RRC) reconfiguration is required, that is, it cannot be flexibly adjusted
The delay of RRC reconfiguration is as high as 100-200ms, which may affect the performance of analog beamforming in some application scenarios

Embodiment Construction

[0351] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0352] The background technology of the embodiments of the present invention is introduced below.

[0353] A wireless transmitter (such as a base station, terminal) with multiple antennas can transmit wireless signals by forming beams pointing in specific directions through beamforming. The width and direction of the beam can be flexibly adjusted by applying appropriate weights on each antenna element. Beamforming can be performed in the digital or analog domain. When each antenna unit has an independent baseband module, each antenna unit can independently control the amplitude and phase of the signal transmitted on the antenna unit, so that digital beamforming can be realized. ...

Abstract

Disclosed are an uplink transmission indication method, a terminal, a base station and a computer storage medium, which are used for providing a new uplink transmission indication method so as to flexibly perform dynamic indication of an uplink transmission beam, thereby improving the adjustment efficiency of the beam. The uplink transmission indication method is applied to network side equipmentand comprises the steps of sending a configuration message to a terminal, wherein the configuration message is used for configuring at least two sounding reference signal (SRS) resource sets for the terminal, and the SRS resource sets are used for obtaining channel state information (CSI) of a first uplink transmission mode; receiving the SRS under the configuration message sent by the terminal, and determining an uplink transmission parameter of a first uplink signal according to the received SRS; and sending the determined uplink transmission parameter to the terminal to indicate the terminal to transmit a first uplink signal according to the uplink transmission parameter.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for uplink transmission indication, a terminal, a base station and a computer storage medium. Background technique [0002] At present, the base station configures a sounding reference signal (Sounding Reference Signal, SRS) resource set for the terminal, and the uplink transmission beam is semi-statically configured for each SRS resource or for an SRS resource set. When it is necessary to change the uplink transmission beam of an SRS resource When , radio resource control (Radio Resource Control, RRC) reconfiguration needs to be performed, that is, it cannot be adjusted flexibly. However, the delay of RRC reconfiguration is as high as 100-200ms, which may affect the performance of analog beamforming in some application scenarios. Contents of the invention [0003] Embodiments of the present invention provide a method for uplink transmission indication,...
