摘要: Embodiments of this application are applicable to the field of communications technologies, and provide a physical downlink control channel PDCCH monitoring method, an apparatus, and a terminal. The method includes: receiving, by the terminal, search space information configured by a network device, where the search space information includes information about a first search space set group and a second search space set group; and when the terminal monitors a PDCCH based on the second search space set group, if downlink control information DCI used for data scheduling is received, stopping monitoring a PDCCH based on the second search space set group, and starting monitoring a PDCCH based on the first search space set group. According to the method, switching between the search space set groups may be performed based on a type of information received by the terminal. When a monitoring period of each search space in the second search space set group is relatively large, and a monitoring period of each search space in the first search space set group is relatively small, switching of the terminal to the first search space set group to monitor a PDCCH helps to quickly complete data transmission and reduce a data transmission delay.

摘要: A reference signal transmission method is provided, to reduce power consumption. The method may be applied to time-frequency tracking. The method in embodiments of this application includes: A network device sends configuration information of a reference signal RS to a terminal device, where the configuration information is used to indicate at least one periodic target sending time period of the RS; and the network device sends the RS in a first target sending time period based on a first periodicity, where the first target sending time period belongs to the at least one periodic target sending time period. In this case, the RS is sent only in a part of the target sending time period, that is, the RS is not an always-on signal, and wake-up duration of UE is short. This helps UE reduce power consumption.

摘要: This application provides a wireless communication method, device, and system. The wireless communication method includes: A terminal device receives first information from a network device, where the terminal device currently uses a first BWP, and the first information indicates that in minKO time units after the terminal device receives scheduling downlink control information (DCI), there is no downlink shared channel (PDSCH) scheduled by the scheduling DCI, and/or in minK2 time units after the terminal device receives the DCI, there is no uplink shared channel (PUSCH) scheduled by the scheduling DCI; the terminal device receives the scheduling DCI from the network device, where the scheduling DCI indicates the terminal device to switch from the first BWP to a target BWP; and the terminal device determines a first time period based on a bandwidth part (BWP) switch delay and the first information, where the delay includes N time units. After the first time period since the terminal device receives the scheduling DCI, the terminal device has a capability of receiving the PDSCH or sending the PUSCH on the target BWP.

摘要: This application provides a communication transmission method and a device. The method includes: A terminal device receives first indication information from a network device; and the terminal device skips PDCCH monitoring in a first cell based on the first indication information. The first cell is a single cell; the first cell is a primary cell Pcell; the first cell is a Pcell and at least one Scell of secondary cells Scells in which PDCCH monitoring is skipped when PDCCH monitoring is skipped in the Pcell; or the first cell is a Pcell and all activated Scells of Scells. The method effectively avoids PDCCH-only of the terminal device in the first cell, and better reduces power consumption. In addition, when the first cell includes both the Pcell and the Scell, a mechanism of simultaneously skipping PDCCH monitoring in both the Pcell and the Scell can be implemented. This further effectively reduces power consumption of the terminal device and reduces signaling transmission.
