Abstract
A wireless device may be configured for secondary cell activation. Transmission configuration indicator states of the wireless device may be configured in a reference bandwidth part of a reference cell, for example, if transmission configuration indicator states may not be configured for a downlink bandwidth part of a secondary cell. A parameter may be used to indicate which transmission configuration indicator state is to be used for receiving and/or measuring reference signals, which may expedite secondary cell activation for the wireless device.
Claims20
A method comprising:
- receiving, by a wireless device, one or more messages indicating:
- one or more reference signal configuration parameters for activation of a secondary cell (SCell);
- and
- a unified transmission configuration indicator (TCI) state reference parameter indicating a reference bandwidth part (BWP) of a reference cell;
- receiving a message indicating a first reference signal configuration parameter, of the one or more reference signal configuration parameters, wherein the first reference signal configuration parameter comprises:
- a TCI state index indicating a first TCI state in the reference BWP of the reference cell;
- and
- a resource set index indicating one or more reference signals;
- and
- receiving, via a first active downlink BWP of the SCell and based on the first TCI state, the one or more reference signals.
A method comprising:
- sending, by a base station, one or more messages indicating:
- one or more reference signal configuration parameters for activation of a secondary cell (SCell);
- and
- a unified transmission configuration indicator (TCI) state reference parameter indicating a reference bandwidth part (BWP) of a reference cell;
- sending a message indicating a first reference signal configuration parameter, of the one or more reference signal configuration parameters, wherein the first reference signal configuration parameter comprises:
- a TCI state index indicating a first TCI state in the reference BWP of the reference cell;
- and
- a resource set index indicating one or more reference signals;
- and
- sending, via a first active downlink BWP of the SCell and based on the first TCI state, the one or more reference signals.
A method comprising:
- receiving, by a wireless device, a message indicating a first reference signal configuration parameter comprising:
- a transmission configuration indicator (TCI) state index indicating a TCI state in a reference bandwidth part (BWP) of a reference cell for activation of a secondary cell (SCell);
- and
- a resource set index indicating one or more reference signals;
- receiving, via an active downlink BWP of an SCell and based on the TCI state, the one or more reference signals;
- and
- determining one or more radio link qualities of the one or more reference signals.
