AI Technical Summary

Technical Problem

Existing wireless communication systems face challenges in optimizing transmission and reception using multiple panels, particularly in determining the appropriate antenna panels, precoding, and power allocation for simultaneous multi-panel transmission, which can lead to inefficiencies and suboptimal performance.

Method used

A wireless transmit-receive unit (WTRU) is configured to dynamically select antenna panels and determine operating modes for simultaneous multi-panel (SMP) transmission, adjusting power scaling and precoding based on received instructions and parameters, allowing for optimized multi-panel communication.

Benefits of technology

This approach enhances communication efficiency by optimizing antenna panel usage, power allocation, and precoding, leading to improved performance in wireless transmission and reception.

Abstract

A wireless transmit / receive unit (WTRU) may receive configuration information indicating a first SRS resource set and a second SRS resource set. The WTRU may receive a first DCI including a first UL grant. The first DCI may include a first instruction to transmit simultaneously using multiple panels. The first DCI may include a second instruction associating each of the multiple panels with a respective one of the first or second SRS resource sets for the first UL grant. The second instruction may indicate that the first SRS resource set should be used for a first transmission using the first panel and the second SRS resource set should be used for a second transmission using the second panel, or vice versa. The WTRU may transmit a first transmission over the first panel and a second transmission over the second panel simultaneously according to the first and second instructions.
