AI Technical Summary

Technical Problem

When the existing wireless communication system updates the transmission configuration indicator status (TCI status) for user equipment (UEs) of multiple component carriers, there is a high overhead and delay, affecting network throughput, especially in the frequency range 2 (FR2) In beam management, the UE needs to receive spatial information of multiple component carriers, resulting in a decrease in network efficiency.

Method used

Component carriers are configured using Radio Resource Control (RRC) signaling by transmitting a transmission configuration indicator status (TCI status) indicating multiple component carriers between a base station and a user equipment (UE) and receiving or sending a physical channel according to these states, and configuring component carriers using Radio Resource Control (RRC) signaling List and cell identifiers to optimize the management and update process of TCI status.

Benefits of technology

Reduces network overhead and delay, improves network throughput and efficiency, supports more efficient frequency range 2 (FR2) beam management and coordination of multiple component carriers, and improves the transmission performance of user equipment.

Abstract

Certain aspects of the present disclosure provide techniques for user equipment (UE)-specific transmissions via multiple component carriers. A method that may be performed by a user equipment (UE) includes: receiving a signal indicating multiple component carriers (CCs) and corresponding transmission configuration indicator states (TCI states) for the CCs; and receiving a physical channel according to one of the corresponding TCI states on one or more CCs in the CCs.
