Abstract: A communications device determines index values of n first control channel elements (CCEs) occupied by a physical downlink control channel (PDCCH) candidate in a control resource set (CORESET) in a first CCE set and index values of m second CCEs occupied by the PDCCH candidate in the CORESET in a second CCE set. The CORESET is divided into a first second physical time-frequency resource area and a second physical time-frequency resource area. The first physical time-frequency resource area is different from the second physical time-frequency resource area in time domain and/or frequency domain. A quantity of CCEs included in the first CCE set is determined based on a quantity of resource element groups (REGs) included in a first physical time-frequency resource. A quantity of CCEs included in the second CCE set is determined based on a quantity of REGs included in a second physical time-frequency resource.

Abstract: A method for stopping monitoring a physical downlink control channel. A network device sends first DCI to a terminal device on an active DL BWP. The terminal device runs a timer, where the timer is used for BWP switching. The terminal device stops, based on the first DCI, monitoring a PDCCH within a first duration, and suspends running of the timer. The terminal device continues to run the timer after the first duration. The terminal device performs DL BWP switching when the timer expires. The network device runs a timer, suspends running of the timer within a first duration, and continues to run the timer after the first duration. The network device performs DL BWP switching when the timer expires.

Abstract: Example communication methods and example apparatuses are provided. One example method includes receiving, by a terminal device, bandwidth part (BWP) switching indication information from a network device in a slot n, wherein the BWP switching indication information includes a first value and a minimum value of a first slot difference, and the first slot difference is an interval between a slot in which first data is transmitted and the slot n. The terminal device can then determine a first target slot based on the first value of the first slot difference and the slot n. The terminal device can then start to use the minimum value of the first slot difference in a start position of the first target slot.
