Abstract: 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.

Abstract: A communication method and apparatus is provided. The method includes: camping on a first cell by a terminal device. The method further includes: determining, by the terminal device, to access a second cell in response to: receiving a paging message from the first cell, determining that there is to-be-transmitted uplink information, or determining that there is a to-be-transmitted non-multicast service. A frequency of the first cell is different from a frequency of the second cell. The terminal device may not perform uplink transmission or may receive only a multicast service in the first cell so that energy consumption of cell measurement and beam selection is reduced. In addition, resource utilization of a communication system can be improved through flexible deployment.
