Title:
REDUCTION OF OVERHEAD ASSOCIATED WITH CONFIGURATION OF TRANSMISSION FUNCTIONS RELATING TO SOUNDING REFERENCE SIGNALS
Document Type and Number:
WIPO Patent Application WO/2021/102803
Kind Code:
A1
Abstract:
A base station may configure a user equipment (UE) to perform sounding reference signal (SRS) transmissions using an SRS resource set. The SRS resource set may be configured for two or more functions, e.g., functions such as codebook-based SRS transmission, non-codebook-based SRS transmission, antenna port switching, beam management, etc. By enabling the use of such dual function (or multi-function) SRS resource sets, the average data rate associated with configuration transmissions to the UE may be reduced.
