Restarting a deactivation timer of a secondary cell in a wireless network
A base station transmits, to a wireless device, a resource assignment indicating a plurality of time intervals of a secondary cell for communicating with the wireless device. The base station restarts a deactivation timer associated with the secondary cell in response to communicating, via the secondary cell, an uplink packet or a downlink packet with the wireless device during a first time interval of the plurality of time intervals.
1. A base station comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the base station to:
transmit, to a wireless device, radio resource control (RRC) signaling comprising parameters for a plurality of time intervals of a secondary cell for communicating with the wireless device;
transmit, via a physical downlink control channel (PDCCH), downlink control information (DCI) comprising a resource block assignment for the plurality of time intervals of the secondary cell for communicating with the wireless device; and
restart a deactivation timer associated with the secondary cell in response to communicating, via the secondary cell, an uplink packet or a downlink packet with the wireless device during a first time interval of the plurality of time intervals.
2. The base station of claim 1 , wherein the instructions further cause the base station to restart 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 base station of claim 1 , wherein the RRC signaling comprises an index for the plurality of time intervals.
4. The base station of claim 3 , wherein the DCI comprises:
the index for the plurality of time intervals; and
a resource block assignment for the plurality of time intervals.
5. The base station of claim 4 , wherein the instructions further cause the base station to restart 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.
6. The base station of claim 4 , wherein:
the uplink packet comprises an uplink transport block; and
the downlink packet comprises a downlink transport block.
7. The base station of claim 4 , wherein the RRC signaling comprises a time duration for the plurality of time intervals.
8. The base station of claim 1 , wherein the first time interval is a first occurrence in the plurality of time intervals.
9. The base station of claim 1 , wherein a time interval of the plurality of time intervals comprises a subframe.
10. The base station of claim 1 , wherein the RRC signaling comprises a bitmap indicating one or more time intervals of the plurality of time intervals.
11. A base station comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the base station to:
transmit, to a wireless device, radio resource control (RRC) signaling comprising parameters of a resource assignment for a plurality of time intervals of a secondary cell for communicating with the wireless device; and
restart a deactivation timer associated with the secondary cell in response to communicating, via the secondary cell, an uplink packet or a downlink packet with the wireless device during a first time interval of the plurality of time intervals.
12. The base station of claim 11 , wherein the instructions further cause the base station to restart 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.
13. The base station of claim 11 , wherein the RRC signaling comprises an index for the plurality of time intervals.
14. The base station of claim 13 , wherein the instructions cause the base station to transmit, via a physical downlink control channel (PDCCH), downlink control information (DCI) comprising a resource block assignment for the plurality of time intervals of the secondary cell for communicating with the wireless device, wherein the DCI comprises:
the index for the plurality of time intervals; and
a resource block assignment for the plurality of time intervals.
15. The base station of claim 14 , wherein the instructions further cause the base station to restart 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.
16. The base station of claim 14 , wherein:
the uplink packet comprises an uplink transport block; and
the downlink packet comprises a downlink transport block.
17. The base station of claim 14 , wherein the RRC signaling comprises a time duration for the plurality of time intervals.
18. The base station of claim 11 , wherein the first time interval is a first occurrence in the plurality of time intervals.
19. The base station of claim 11 , wherein a time interval of the plurality of time intervals comprises a subframe.
20. The base station of claim 11 , wherein the RRC signaling comprises a bitmap indicating one or more time intervals of the plurality of time intervals.
