Deactivation timer management and cross carrier scheduling in a wireless device and wireless network
First Claim
1. A method comprising:
- receiving, by a wireless device, at least one radio resource control (RRC) message comprising configuration parameters of a plurality of cells comprising a first cell and a second cell, the configuration parameters comprising;
at least one deactivation timer value for a first deactivation timer of the first cell and a second deactivation timer of the second cell; and
at least one cross carrier scheduling parameter indicating a configuration of cross carrier scheduling, wherein;
a first control channel of the first cell carries downlink scheduling information for packets received by the wireless device via a downlink data channel of the first cell; and
a second control channel of the second cell carries uplink scheduling information for second packets transmitted by the wireless device via an uplink data channel of the first cell;
receiving a first downlink control information (DCI) for uplink transmission on the first cell;
restarting the first deactivation timer and the second deactivation timer in response to the first DCI;
receiving a second DCI for downlink transmission on the first cell;
restarting the first deactivation timer and not the second deactivation timer in response to the second DCI;
deactivating the first cell in response to the first deactivation timer expiring; and
deactivating the second cell in response to the second deactivation timer expiring.

Abstract
A wireless device receives RRC message(s) with configuration parameters comprising deactivation timer value(s) for a first deactivation timer of a first cell and a second deactivation timer of a second cell, and cross carrier scheduling parameter(s). A first control channel of the first cell carries downlink scheduling information via a downlink data channel of the first cell. A second control channel of the second cell carries uplink scheduling information via an uplink data channel of the first cell. The first and second deactivation timers restart in response to receiving a first DCI for uplink transmission on the first cell. The first deactivation timer and not the second deactivation timer restart in response to receiving a second DCI for downlink transmission on the first cell received. The first cell deactivates in response to the first deactivation timer expiring. The second cell deactivate in response to the second deactivation timer expiring.
