摘要： 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.

摘要： This application relates to the field of communications technologies, and discloses a slot format indication method, a device, and a system. The method includes: generating, by a network device, first indication information, and sending the first indication information to a terminal device; and after receiving the first indication information, determining, by the terminal device, slot formats of M CCs based on the first indication information. The first indication information indicates K slot formats. The K slot formats are the slot formats of the M CCs configured for the terminal device. At least one slot format in the K slot formats is corresponding to at least two CCs in the M CCs. Configuration parameters of the at least two CCs have at least one type of same parameter. The configuration parameter includes at least one of the following parameters: a subcarrier spacing, a cyclic prefix, a bandwidth, or a frequency band.

摘要： 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.

摘要： This disclosure relates to a communication method and a device. When a terminal device determines not to monitor DCP on a first DCP monitoring occasion, the terminal device wakes up on a first group of carriers within first DRX on duration associated with the first DCP monitoring occasion, and wakes up or sleeps on a second group of carriers within second DRX on duration associated with the first DCP monitoring occasion. The first group of carriers includes one or more carriers configured for the terminal device, a first DRX configuration is applied to the first group of carriers, the first DRX on duration corresponds to the first DRX configuration, the second group of carriers includes one or more carriers configured for the terminal device, a second DRX configuration is applied to the second group of carriers, and the second DRX on duration corresponds to the second DRX configuration.

摘要： A bandwidth part processing method includes receiving, by a terminal, a first information and a second information from a network device. The first information indicates that at least one default bandwidth part (BWP) corresponds to at least two active BWPs, the second information indicates that the at least two active BWPs correspond to at least one first timer, and the at least one first timer is useable by the terminal to perform deactivation processing on at least one of the at least two active BWPs. The method further includes performing, by the terminal, deactivation processing on the at least one of the at least two active BWPs, and activation processing on a BWP in the at least one default BWP based on the first and second information, or performing deactivation processing on the at least one of the at least two active BWPs based on the first and second information.
