An apparatus, such as a UE, receives signaling that indicates a radio link control (RLC) configuration for a radio bearer associated with an RLC entity. The UE establishes the RLC entity based on the RLC configuration, where the RLC entity includes multiple logical channels. The UE routes a set of data packets via the logical channels based on parameters associated with at least one of the logical channels or the set of data packets. For example, a first portion of data packets of the set of data packets is routed via a first logical channel associated with a first priority and a second portion of data packets of the set of data packets is routed via a second logical channel associated with a second priority. The second priority is higher than the first priority. ## Claims ### Claim 1 A user equipment (UE) for wireless communication, comprising: at least one memory; and at least one processor coupled with the at least one memory and configured to cause the UE to: receive signaling that indicates a radio link control (RLC) configuration for a radio bearer associated with an RLC entity, wherein the RLC entity comprises a plurality of logical channels;
