Abstract
Control channel repetition may be used in wireless communications. A base station may send repeated downlink control information (DCI) or physical downlink control channel (PDCCH) to a wireless device. The base station may send configuration parameters to the wireless device to indicate a plurality of coresets and indicate whether a particular DCI field, such as a transmission configuration indicator (TCI) field, will be present in the repeated DCI. Wireless resources may be determined by the wireless device based on a candidate of the last configured repetition.
Claims20
A method comprising:
- sending, by a base station to a wireless device, one or more configuration parameters associated with a plurality of control resource sets (coresets) for a plurality of repetitions of downlink control information (DCI), wherein presence or absence of a transmission configuration indicator (TCI) field is the same for the plurality of repetitions of the DCI;
- and
- sending, by the base station to the wireless device via the plurality of coresets, the plurality of repetitions of the DCI.
A method comprising:
- receiving, by a wireless device from a base station, one or more configuration parameters for a plurality of repetitions of downlink control information (DCI), wherein the one or more configuration parameters indicate:
- a first physical downlink control channel (PDCCH) candidate of a first search space;
- and
- a second PDCCH candidate of a second search space;
- receiving, via a first monitoring occasion of the first PDCCH candidate, a repetition of the DCI indicating a scheduling offset between the receiving the repetition of the DCI and a time slot for radio resources;
- determining, based on the scheduling offset and a second monitoring occasion of the second PDCCH candidate, and further based on no repetition of the DCI being received via the second monitoring occasion of the second PDCCH candidate, the time slot;
- and
- receiving, via the radio resources and based on the time slot, a transport block.
A method comprising:
- receiving, by a wireless device from a base station, one or more configuration parameters associated with a plurality of control resource sets (coresets) for a plurality of repetitions of downlink control information (DCI), wherein presence or absence of a transmission configuration indicator (TCI) field is the same for the plurality of repetitions of the DCI;
- and
- receiving, by the wireless device from the base station via the plurality of coresets, the plurality of repetitions of the DCI.
