Abstract
A wireless device may use different power control sets to communicate with different transmission reception points (TRPs). The power control set for communicating with a particular TRP may be selected from at least two power control sets configured for a resource (such as a bandwidth part (BWP)), for example, based on a transmission configuration indicator (TCI) state corresponding to the particular TRP.
Claims19
A method comprising:
- receiving, by a wireless device, a control command indicating a transmission configuration indicator (TCI) state;
- receiving downlink control information (DCI) scheduling transmission of a downlink signal, wherein a time offset between the DCI and the downlink signal is less than a threshold;
- and based on the time offset being less than the threshold and the TCI state being associated with a physical cell identifier (PCI) of a serving cell, receiving the downlink signal using the TCI state.
A method comprising:
- monitoring, by a wireless device, a control resource set (CORESET) based on a first transmission configuration indicator (TCI) state;
- receiving a control command indicating a second TCI state;
- receiving downlink control information (DCI) scheduling transmission of a downlink signal, wherein a time offset between the DCI and the downlink signal is less than a threshold;
- and based on the time offset being less than the threshold and the second TCI state being associated with a second physical cell identifier (PCI) different from a PCI of a serving cell, receiving the downlink signal using the first TCI state.
1 more element
A method comprising:
- receiving, by a wireless device, one or more configuration parameters indicating:
- a plurality of uplink power control sets for a serving cell;
- and at least two uplink power control sets of the plurality of uplink power control sets for an uplink bandwidth part (BWP) of the serving cell;
- receiving downlink control information (DCI) indicating a transmission configuration indicator (TCI) state;
- and
- transmitting, via the uplink BWP of the serving cell and using a transmission power that is based on a first uplink power control set of the at least two uplink power control sets, an uplink signal based on:
- the one or more configuration parameters not indicating an uplink power control set index for the TCI state;
- and the first uplink power control set being associated with a physical cell identifier (PCI) of the serving cell.
