摘要： Example communication methods and apparatus are described. In one example method, a first cell includes a plurality of terminal devices that can transmit uplink data on a same uplink time-frequency resource. A first terminal device in the plurality of terminal devices determines a reference time domain location based on a preconfigured uplink time-frequency resource, where the reference time domain location is the same as a reference time domain location determined by another terminal device in the plurality of terminal devices. The first terminal device determines a time domain location that is (first duration×N H+second duration×(N−1)) away from the reference time domain location as a start time domain location of X gaps. The first terminal device further determines a time domain location that is (first duration×(M−1)+second duration x (M−1)) away from the reference time domain location as a start time domain location of Y first durations, where Y=X or Y=X+1. Uplink data is sent by the first terminal device to a network device on a first time-frequency resource used to transmit uplink data.

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.
