Abstract
A wireless device monitors a downlink control channel of a transmission reception point (TRP) on an active bandwidth part (BWP) of a cell, where the TRP is in an active state. First channel state information reports of the TRP for the active BWP are transmitted. The TRP transitions from the active state into a dormant state in response to a first time period of inactivity on the TRP. The monitoring is stopped. Second channel state information reports of the TRP for the active BWP are transmitted when the TRP is in the dormant state.
Claims20
A method comprising:
- monitoring, by a wireless device:
- a first downlink control channel of a first transmission reception point (TRP) of a cell, in an active state, on an active bandwidth part (BWP) of a cell;
- and
- a second downlink control channel of a second TRP of the cell, in the active state, on the active BWP;
- transmitting first channel state information reports of the first TRP of the cell and the second TRP of the cell for the active BWP;
- transitioning the second TRP of the cell from the active state into a dormant state, wherein the active state, the dormant state, and an inactive state are different from one another;
- stopping the monitoring of the second downlink control channel of the second TRP of the cell, based on the transition from the active state into the dormant state;
- maintaining the first TRP of the cell in the active state, while the second TRP of the cell is in the dormant state;
- and
- transmitting second channel state information reports of the second TRP of the cell, while the second TRP of the cell is in the dormant state, for the active BWP.
