Claim Text:
1. A base station configured to serve a user equipment device (UE) over an air interface, wherein the base station comprises: a wireless communication interface, wherein the air interface defines an uplink control channel and further defines an uplink shared channel, the base station being configured to receive from the UE on the uplink control channel a scheduling request (SR) defining a request from the UE for uplink shared channel resource allocation, wherein the base station has a buffer status report (BSR) mode of operation in which the base station responds to the SR received from the UE on the uplink control channel at least in part by (i) allocating to the UE a first extent of uplink shared channel resources for use to carry from the UE to the base station a BSR indicating a quantity of bearer data to be transmitted from the UE to the base station, (ii) receiving the BSR from the UE on the allocated first extent of uplink shared channel resources, and (iii) in accordance with the received BSR, allocating to the UE further uplink shared channel resources for bearer data communication from the UE to the base station, wherein the base station has a non-BSR mode of operation in which the base station responds to the SR received from the UE on the uplink control channel by allocating to the UE a second extent of uplink control channel resources for bearer data communication from the UE to the base station without first receiving from the UE a BSR for the bearer data communication, the second extent being greater than the first extent, and wherein the base station is configured to selectively operate in either the BSR mode or the non-BSR mode based on a type of bearer data the UE is communicating.
