US-12621890-B2 - Asymmetric channel

Abstract

A base station may receive, from a first wireless device, a first radio resource control (RRC) message indicating that a communication associated with a bearer is asymmetric. The bearer may be associated with a service that needs a symmetric communication. The base station may also send, to the first wireless device and based on the first RRC message, a second RRC message that includes radio resource configuration parameters of the first wireless device.
