Title:
キャリアアグリゲーションにおけるＳＲＳアンテナ切替えのための方法および装置
Document Type and Number:
Japanese Patent JP7164593
Kind Code:
B2
Abstract:
Certain aspects of the present disclosure relate to communication systems, and more particularly, to improving performance for sounding reference signal (SRS) antenna switching in carrier aggregation (CA). A method is provided, that may be performed by a user equipment (UE) for wireless communications. The method includes determining one or more band combinations that share an antenna switch and sending a list of one or more bands in the one or more band combinations to a base station (BS). The BS receives the list and schedules the UE based on the received list.
