Abstract

The present invention provides a method for sending an SRS and a mobile terminal. The method includes: obtaining the moving speed of the mobile terminal; and sending the SRS in an SRS sending manner corresponding to the moving speed. The invention can improve the flexibility of SRS sending.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for sending an SRS and a mobile terminal. Background technique [0002] The fifth-generation (5th-Generation, 5G) New Radio (NR) mobile communication system introduces a number of antenna enhancement technologies, which greatly improve spectrum efficiency, cell coverage and system flexibility. In a multi-antenna system, digital signal processing technology and the spatial characteristics of signal transmission can be used to adjust the weight of the transmitted signal on each antenna element to correct the signal propagation characteristics. Beamforming technology generates spatially oriented beams by modifying signal weights, which can increase system capacity without significantly increasing system complexity. [0003] The beamforming technology can be divided into: a codebook based beamforming technology and a channel reciprocity b...
