AI Technical Summary
Technical Problem
The existing 5G NR SRS transmission with antenna switching faces high overhead and inefficient resource utilization due to fixed associations between Tx and Rx ports, leading to potential performance degradation in next-generation 6G systems.
Method used
Adaptive selection of Rx ports at the user equipment based on CSI-RS measurements, allowing flexible SRS configurations and reducing the number of ports used for probing, informed by the base station.
Benefits of technology
Reduces UL resource load and maintains system performance by optimizing the selection of Rx ports for SRS transmission, ensuring efficient use of resources.

Abstract
FIELD: wireless communication.SUBSTANCE: method comprises the steps of: receiving an instruction from a base station to transmit an SRS with adaptive switching of user equipment ports at the user equipment; selecting one or more antenna ports of the user equipment for sounding based on measurements of the channel state information reference signal (CSI-RS) transmitted by the base station, wherein the number of selected antenna ports of the user equipment is determined according to said instruction received from the base station; and transmitting the SRS corresponding to the selected one or more antenna ports of the user equipment.EFFECT: using a smaller number of resources for transmitting sounding reference signals (SRS) by user equipment and, accordingly, a smaller load on the uplink (UL), while maintaining the required system characteristics due to the possibility of adaptive selection of antenna ports subject to SRS sounding on the user equipment side.19 cl, 24 dwg, 3 tbl
