Secondary cell deactivation timer management in a wireless network
A wireless device receives a resource assignment for communications in a plurality of time intervals of a secondary cell. A deactivation timer, associated with the secondary cell, is restarted in response to communicating an uplink packet or a downlink packet during a first time interval of the plurality of time intervals.
1. A method comprising:
receiving, by a wireless device, a resource assignment indicating a plurality of time intervals of a secondary cell for communicating with a base station; and
restarting a deactivation timer associated with the secondary cell in response to communicating an uplink packet or a downlink packet with the base station during a first time interval of the plurality of time intervals.
2. The method of claim 1 , further comprising
restarting the deactivation timer associated with the secondary cell in response to communicating a second uplink packet or a second downlink packet during a second time interval of the plurality of time intervals.
3. The method of claim 1 , wherein the first time interval is a first occurrence of the plurality of time intervals.
4. The method of claim 1 , wherein the resource assignment is for a period of time.
5. The method of claim 1 , wherein a time interval in the plurality of time intervals comprises a subframe.
6. The method of claim 1 , wherein the first time interval is a last time interval of the plurality of time intervals.
7. The method of claim 1 , wherein:
the communicating the uplink packet or the downlink packet is based on the resource assignment; and
uplink packets or downlink packets communicated via the plurality of time intervals use common parameters comprising a resource block assignment.
8. The method of claim 1 , wherein uplink packets or downlink packets communicated via the plurality of time intervals use common parameters comprising a modulation and coding scheme.
9. The method of claim 1 , wherein the resource assignment comprises an index referencing to the plurality of time intervals.
10. The method of claim 1 , wherein a radio resource control (RRC) message comprises configuration parameters of the plurality of time intervals.
11. The method of claim 1 , wherein a radio resource control (RRC) message comprises configuration parameters indicating the plurality of time intervals.
12. The method of claim 1 , wherein the resource assignment comprises an index that is used to determine the plurality of time intervals.
13. The method of claim 1 , wherein the resource assignment comprises a resource block assignment.
14. The method of claim 1 , wherein the resource assignment comprises:
an index indicating the plurality of time intervals; and
a resource block assignment for the plurality of time intervals.
15. The method of claim 1 , wherein: the uplink packet comprises an uplink transport block; and
the downlink packet comprises a downlink transport block.
16. The method of claim 1 , further comprising deactivating the secondary cell based on the deactivation timer expiring.
17. The method of claim 1 , wherein the resource assignment is included in a downlink control information received via a downlink physical control channel.
18. The method of claim 1 , wherein the resource assignment is included in a radio resource control (RRC) message.
19. The method of claim 1 , wherein the plurality of time intervals comprises a group of subframes.
20. The method of claim 1 , wherein a radio resource control (RRC) message comprises configuration parameters of the resource assignment for the plurality of time intervals, wherein the configuration parameters comprise a time duration.
