A user equipment may be configured to transmit to a radio network node a partial buffer status report to minimize use of uplink resources for transmission of control information. A partial buffer status report may comprise one or more volume index/indices indicative of buffered traffic volume corresponding to one or more logical channel group(s), individually with respect to which buffered traffic corresponding to a logical channel group satisfies a partial buffer status report reporting criterion. A partial buffer status report may avoid indicating buffered traffic volume corresponding to a logical channel group with respect to which buffered traffic does not satisfy a partial buffer status report reporting criterion. A partial buffer status report reporting criterion may be a volume criterion or a delay criterion. During a period of uplink channel congestion, the user equipment may avoid transmitting a full buffer status report.

Dynamic partial buffer status reporting

A radio access network node may group traffic packets of a traffic flow directed to a user equipment according to quality-of-service metric targets associated with the packets. The node may append a group quality-of-service indication indicative of a group quality-of-service to a group of packets associated with a less stringent group quality-of-service metric target than is associated with the traffic flow. The group quality-of-service indication may be contained in a medium access control control element and may comprise an index or a quality-of-service metric target that is configured via a packet group configuration. Packets associated with different quality of service metric targets may be transmitted in the same transport block. The user equipment may avoid requesting retransmission of an unsuccessfully decoded packet based on the group quality of service indication, even if the unsuccessfully decoded packet would otherwise result in a violation of a quality-of-service associated with the traffic flow.
