Abstract

The embodiment of the invention provides a method for determining antenna port mapping and a terminal, and the method comprises the steps: determining mapping of the antenna ports of an SRS accordingto the number of the antenna ports of the SRS, the SRS being an SRS of which the comb size is N, N being an even number greater than 4, and the number of the antenna ports being 1, 2 or 4. According to the embodiment of the invention, the coverage effect and the audibility of the SRS can be improved.

Description

technical field

[0001] The present invention relates to the technical field of communication, in particular to a method for determining antenna port mapping and a terminal. Background technique

[0002] In the communication system, the sounding reference signal (Sounding Reference Signal, SRS) can be used for beam management (Beam management), codebook-based (Codebook) transmission, non-codebook-based (non-Codebook) transmission, antenna switching (Antenna Switching) ) sending or positioning etc. However, the current communication system can only support SRS transmission with a comb size of 2 (abbreviated as comb-2) and a comb size of 4 (abbreviated as comb-4). Difference. Contents of the invention

[0003] Embodiments of the present invention provide a method for determining antenna port mapping and a terminal, so as to solve the problems of relatively poor coverage effect and audibility of SRS.

[0004] In the first aspect, an embodiment of the present invention provi...
