Abstract

A wireless device receives at least one message comprising configuration parameters of a plurality of cells. The at least one message comprises a deactivation timer value for at least one deactivation timer of a plurality of secondary cells. The wireless device receives a scheduling packet for a group of cells and/or a group of subframes. The wireless device restarts one or more deactivation timers.

First claim

What is claimed is:

1 . A method comprising:
receiving, by a wireless device, at least one message comprising:
configuration parameters of a plurality of cells; and
a deactivation timer value for at least one deactivation timer of a plurality of secondary cells;
receiving a scheduling packet for a group of cells comprising a first plurality of secondary cells in the plurality of secondary cells; and restarting each deactivation timer corresponding to each of the first plurality of cells.

2 . The method of claim 1 , wherein the scheduling packet indicates one or more resource allocations and one or more transmission formats for one or more packets transmitted on the first plurality of secondary cells.

3 . The method of claim 2 , further comprising transmitting the one or more packets to a base station.

4 . The method of claim 1 , wherein the scheduling packet indicates one or more resource allocations and one or more transmission formats for one or more packets received on the first plurality of secondary cells.

5 . The method of claim 4 , further comprising receiving the one or more packets from a base station.

6 . The method of claim 1 , further comprising maintaining each deactivation timer for each of the first plurality of secondary cells.

7 . The method of claim 1 , wherein the scheduling packet is received on a downlink physical control channel.

8 . The method of claim 1 , wherein the at least one message comprises parameters indicating the first plurality of cells in the group of cells.

9 . A method comprising:
receiving, by a wireless device, at least one message comprising:
configuration parameters of a plurality of cells; and
a deactivation timer value for at least one deactivation timer of a plurality of secondary cells;
receiving a scheduling packet for a group of subframes of a secondary cell in the plurality of secondary cells; and restarting a deactivation timer associated with the secondary cell in a last subframe of the group of subframes.

10 . The method of claim 9 , wherein the scheduling packet comprises a number of subframes in the group of subframes.

11 . The method of claim 9 , wherein the scheduling packet comprises one or more indexes indicating one or more subframes in the group of subframes.

12 . The method of claim 9 , wherein the scheduling packet indicates one or more resource allocations and one or more transmission formats for one or more packets transmitted in the group of subframes.

13 . The method of claim 12 , further comprising transmitting the one or more packets to a base station.

14 . The method of claim 9 , wherein the scheduling packet indicates one or more resource allocations and one or more transmission formats for one or more packets received in the group of subframes.

15 . The method of claim 14 , further comprising receiving the one or more packets from a base station.

16 . The method of claim 9 , further comprising maintaining the deactivation timer for the secondary cell.

17 . The method of claim 9 , further comprising transmitting the scheduling packet on a downlink physical control channel.

18 . A wireless device comprising:
one or more processors; and memory storing instructions that, when executed, cause the wireless device to:
receive at least one message comprising:
configuration parameters of a plurality of cells; and
a deactivation timer value for at least one deactivation timer of a plurality of secondary cells;

receive a scheduling packet for a group of cells comprising a first plurality of secondary cells in the plurality of secondary cells; and restart each deactivation timer corresponding to each of the first plurality of cells.

19 . The wireless device of claim 18 , further comprising maintaining each deactivation timer for each of the first plurality of secondary cells.

20 . The wireless device of claim 18 , wherein the scheduling packet is received on a downlink physical control channel.
