6. A wireless communication device configured to manage buffer status reporting, the wireless communication device comprising:
processing circuitry; and
a memory, the memory comprising instructions executable by the processing circuitry, whereby the processing circuitry is operative to:
receive a grant from a radio network node in the wireless communication system, the grant pre-scheduling uplink resources for the wireless communication device;
maintain a periodic timer for triggering transmission of periodic Buffer Status Reports (BSRs) on corresponding ones of the pre-scheduled uplink resources; and
suppress transmission of at least one of the periodic BSRs, in dependence on whether or how much uplink data is available for transmission from the wireless device;
wherein, to suppress transmission of at least one of the periodic BSRs, the processing circuitry is configured to suppress transmission of a current one of the periodic BSRs rather than transmitting the current periodic BSR, if [ on the corresponding pre-scheduled uplink resources responsive to ] an amount of uplink data available for transmission from the wireless communication device does not exceed [ indicated in the current periodic BSR not exceeding ] a defined threshold and fewer than a maximum number of consecutively preceding ones of the periodic BSRs have [ having ] been suppressed [ , and otherwise transmit the current periodic BSR responsive to either the amount of uplink data indicated in the current periodic BSR exceeding the defined threshold or the maximum number of consecutively preceding ones of the periodic BSRs having been suppressed] .
