Method and device for controlling timer on buffer status report
View Patent ↗A method for controlling a timer on buffer status report (BSR) is provided in the present invention, and the method is applied to implement the control of the timer on BSR the system to which Carrier Aggregation technology is applied. Said method includes: starting a retransmission BSR timer (retxBSR-Timer) and a BSR periodic reporting timer (periodicBSR-Timer) when a sub frame has a component carrier which has a BSR to be transmitted; restarting the retxBSR-Timer when a sub frame has a component carrier which has new data transmission resources; and restarting the periodicBSR-Timer when a sub frame has a component carrier which has a long BSR or a short BSR to be transmitted. A device for implementing said method is also provided in the present invention.
1. A method, in a User Equipment, UE, in a system with carrier aggregation, of controlling a timer on a Buffer Status Report, BSR, wherein the system includes the UE with a plurality of component carriers and one or more component carriers can be used in a sub-frame, and the plurality of the component carriers correspond to one retransmission BSR timer, retxBSR-Timer, one BSR periodic report timer, and periodic BSR-Timer, the method comprises:
starting the retxBSR-Timer and the periodicBSR-Timer, when a BSR is transmitted over any one of component carriers in a sub-frame;
restarting the retxBSR-Timer when there is a new data transmission resource over any one of component carriers in a sub-frame;
restarting the periodicBSR-Timer when a long BSR or a short BSR is transmitted over any one of component carriers in a sub-frame; and
triggering a regular BSR when the retxBSR-Timer expires; and triggering a periodic BSR when the periodicBSR-Timer expires.
2. A method, in a User Equipment, UE, in a system with carrier aggregation, of controlling a timer on a Buffer Status Report, BSR, wherein the system configures the UE with a plurality of component carriers and one or more component carriers can be used in a sub-frame, and each component carrier corresponds to one retransmission BSR timer, retxBSR-Timer, and one BSR periodic report timer, periodicBSR-Timer, the method comprises:
starting the retxBSR-Timers and the periodicBSR-Timers of all component carriers, when a BSR is transmitted over any one of component carriers in a sub-frame;
restarting the retxBSR-Timer corresponding to a component carrier when there is a new data transmission resource over the component carrier in a sub-frame;
restarting the periodicBSR-Timer corresponding to a component carrier when a long BSR or a short BSR is transmitted over the component carrier in a sub-frame; and
triggering a regular BSR when all the retxBSR-Timers expire; and triggering a periodic BSR when all the periodicBSR-Timers expire.
3. A carrier aggregation-enabled User Equipment, UE, wherein the UE is configured with a plurality of component carriers and one or more component carriers can be used in a sub-frame, the UE comprising:
one retransmission BSR timer, retxBSR-Timer, configured to be started or restarted upon trigger, wherein the plurality of component carriers of the UE correspond to the one retxBSR-Timer;
one BSR periodic report timer, periodicBSR-Timer, configured to be started or restarted upon trigger, wherein the plurality of the component carriers of the UE correspond to the one periodicBSR-Timer; and
a control module configured to trigger the retxBSR-Timer and the periodicBSR-Timer to be started when a BSR is transmitted over any one of component carriers in a sub-frame, to trigger the retxBSR-Timer to be restarted when there is a new data transmission resource over any one of component carriers in a sub-frame, to trigger the periodicBSR-Timer to be restarted when a long BSR or a short BSR is transmitted over any one of component carriers in a sub-frame, and to trigger a regular BSR when the one retxBSR-Timer expires and trigger a periodic BSR when the one periodicBSR-Timer expires.
4. A carrier aggregation-enabled User Equipment, UE, wherein the UE is configured with a plurality of component carriers and one or more component carriers can be used in a sub-frame, the UE comprising:
retransmission BSR timers, retxBSR-Timers, configured to be started or restarted upon trigger, wherein each component carrier corresponds to one retxBSR-Timer,
BSR periodic report timers, periodicBSR-Timers, configured to be started or restarted upon trigger, wherein each component carrier corresponds to one periodicBSR-Timer; and
a control module configured to trigger the retxBSR-Timers and the periodicBSR-Timers of all component carriers to be started when a BSR is transmitted over any one of component carriers in a sub-frame, to trigger the retxBSR-Timer corresponding to a component carrier to be restarted when there is a new data transmission resource over the component carrier in a sub-frame, to trigger the periodicBSR-Timer corresponding to a component carrier to be restarted when a long BSR or a short BSR is transmitted over the component carrier in a sub-frame, and to trigger a regular BSR when all the retxBSR-Timers expire and trigger a periodic BSR when all the periodicBSR-Timers expire.
