CPC H04W 72/23 (2023.01) | 12 Claims |
1. A method for monitoring a physical downlink control channel (PDCCH), applied to user equipment, comprising:
receiving RRC signaling sent by a network side; and
determining a monitoring parameter based on the RRC signaling, wherein the monitoring parameter is associated with at least two of a-downlink control information (DCI) formats of a PDCCH to be monitored by the user equipment, a control channel element (CCE) aggregation level of the to-be-monitored PDCCH, and a CCE aggregation level of the DCI formats of the to-be-monitored PDCCH;
wherein the monitoring parameter comprises at least one of the following: a monitoring period, a monitoring offset, and a monitoring pattern within a slot, wherein the monitoring pattern within a slot is used to indicate one or more time-domain symbols in a CORESET for PDCCH monitoring in a slot, and at least one of the monitoring period, the monitoring offsets, and the monitoring pattern within a slot in monitoring parameter of different DCI formats is different;
wherein the DCI formats comprises at least one of the following:
a first DCI format and a second DCI format of a common search space, wherein the first DCI format is used to schedule a physical uplink shared channel of a serving cell, and the second DCI format is used to schedule a physical downlink shared channel of a serving cell;
a third DCI format and a fourth DCI format of a UE-specific search space, wherein the third DCI format is used to schedule a physical uplink shared channel of a serving cell, and the fourth DCI format is used to schedule a physical downlink shared channel of a serving cell;
a fifth DCI format and a sixth DCI format of the UE-specific search space, wherein the fifth DCI format is used to schedule a physical uplink shared channel of a serving cell, and the sixth DCI format is used to schedule a physical downlink shared channel of a serving cell; and
a seventh DCI format, an eighth DCI format, a ninth DCI format, and a tenth DCI format, wherein the seventh DCI format is used to schedule a physical uplink shared channel of a serving cell, the eighth DCI format is used to schedule a physical downlink shared channel of a serving cell, the ninth DCI format is used to schedule a physical uplink shared channel of a serving cell, and the tenth DCI format is used to schedule a physical downlink shared channel of a serving cell;
wherein, in a same slot, CCE aggregation levels configured in each search spaces are not identical;
wherein the method further comprises:
determining a search space which is used to perform blind detection based on a movement state of the UE, wherein the search space which is used to perform blind detection is corresponding to the CCE aggregation level of the UE; and
dynamically disabling one or more search spaces or CORESETs by receiving DCI.
