Claim of US Patent No. 10,973,013

1. A user equipment (UE) comprising:a higher layer processor configured to acquire a first radio resource control (RRC) configuration including first information for indicating a control resource set (CORESET), to acquire a second RRC configuration including second information for indicating one or more search space sets, and to acquire a third RRC configuration including third information for indicating a resource set for physical downlink shared channel (PDSCH) rate matching, the resource set not available for the PDSCH;
physical downlink control channel (PDCCH) receiving circuitry configured to monitor a PDCCH; and
PDSCH receiving circuitry configured to receive the PDSCH in accordance with the resource set, upon a detection of an indication to apply the resource set in a regular downlink control information (DCI) format in a UE-specific search space (USS) in the PDCCH and configured to receive the PDSCH in accordance with the resource set upon a detection of a fallback DCI format in a common search space (CSS) in the PDCCH;
wherein:
the first information indicates a frequency domain resource allocation of the CORESET and a time domain duration of the CORESET,
the second information indicates a monitoring periodicity and offset of each of the one or more search space sets, the one or more search space sets associated with the CORESET,
the third information indicates a CORESET identifier (ID) associated with the CORESET,
the resource set is determined by at least the frequency domain resource allocation of the CORESET determined by the identity, the time domain duration of the CORESET determined by the identity, and the monitoring periodicity and offset of each of the one or more search space sets,
a subcarrier spacing of the resource set is determined based on a subcarrier spacing of the CORESET,
the regular DCI format includes a DCI field that indicates whether to apply the resource set,
the fallback DCI format does not include the DCI field,
the DCI field is linked to the third RRC configuration, and
the DCI field includes a bit linked to the resource set.
