Abstract
There is provided a method for managing buffer status reporting for a wireless communication device in a wireless communication system. The method comprises checking (S1) condition(s) for suppressing at least one Buffer Status Report, BSR, which is up for transmission, and suppressing (S2) the BSR if the condition(s) is/are fulfilled, wherein the BSR is suppressed when the BSR indicates less than or equal to a first threshold amount of bytes and/or when one or more previous BSRs indicate less than or equal to a second threshold amount of bytes.
Claims8
A method for managing buffer status reporting for a wireless communication device in a wireless communication system, wherein the method comprises:
- receiving a grant from a radio network node in the wireless communication system, the grant pre-scheduling uplink resources for the wireless communication device;
- maintaining a periodic timer for triggering transmission of periodic Buffer Status Reports (BSRs) on corresponding ones of the pre-scheduled uplink resources;
- and
- suppressing 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 suppressing 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 comprises suppressing transmission of a current one of the periodic BSRs rather than transmitting the current periodic BSR, if an amount of uplink data available for transmission from the wireless communication device does not exceed a defined threshold and fewer than a maximum number of consecutively preceding ones of the periodic BSRs have been suppressed.
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 an amount of uplink data available for transmission from the wireless communication device does not exceed a defined threshold and fewer than a maximum number of consecutively preceding ones of the periodic BSRs have been suppressed.
