Quality of service configurations for radio bearers with multiple data flows
Methods, systems, and devices for wireless communication are described. A wireless communications system may establish radio bearers for certain data transmissions between a user equipment (UE) and a base station. A radio bearer may be associated with one or more quality of services (QoS) parameters, such as a bit rate. The base station may indicate to the UE a time window over which to average the bit rate. In some examples, a radio bearer may include multiple data flows. The base station may provide information regarding QoS parameters for each data flow in control signaling, such as a grant.

establish a radio bearer with a network entity;
identify a plurality of configured data flows mapped to the radio bearer; and
receive, from the network entity and after identifying the plurality of configured data flows mapped to the radio bearer, a grant for communications with the network entity, the grant indicating a respective quality of service (QoS) parameter and a respective time window for which the UE averages the respective QoS parameter for each configured data flow of the identified plurality of configured data flows mapped to the radio bearer.
11. The UE of claim 10 , wherein, to receive the grant, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
receive an allocation of bits for a first configured data flow of the identified plurality of configured data flows and an allocation of bits for a second configured data flow of the identified plurality of configured data flows.
12. The UE of claim 11 , wherein:
the allocation of bits for the first configured data flow is configured to satisfy a first QoS priority level, and
