Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a port mapping method and terminal for detecting reference signals. Background Technology

[0002] In NR systems, the Sounding Reference Signal (SRS) can be used for beam management, codebook-based transmission, non-codebook-based transmission, and antenna switching. Terminals can obtain multiple SRS resource sets through higher-layer signaling; each SRS resource set is configured with its purpose, periodic characteristics, and other specifications.

[0003] In Release-15 / 16, SRS resources can occupy the last 6 symbols within a single time slot. Higher-layer signaling can be configured to use 1 / 2 / 4 symbols for SRS transmission, and comb-2 and comb-4 structures in the frequency domain are supported. Release-17 enhances upon Release-15 / 16, allowing the starting position of SRS resources to be any symbol within a single time slot. It also supports a comb-8 structure.

[0004] The existing NR protocol only supports SRS with 1, 2, or 4 ports. To further improve uplink transmission performance, it is necessary to introduce SRS that supports more ports, such as 6 or 8 SRS ports.
