US-20260129517-A1 - Rate Control for Extended Reality in Dual Connectivity

Abstract

A first base station receives, from a second base station, a message comprising a parameter indicating a first recommended bit rate associated with a data radio bearer (DRB) of a wireless device. The first base station sends, to the wireless device, a medium access control (MAC) control element indicating a second recommended bit rate for a logical channel of the DRB
