Abstract: This application provides a communication method and apparatus. In the method, a terminal may obtain a main resource pool used to transmit sidelink data and a supplementary resource pool used to transmit the sidelink data. The terminal may request, based on a requirement of the terminal, a resource in the main resource pool or a resource in the supplementary resource pool to transmit the sidelink data. For example, when the resource in the main resource pool cannot meet a data transmission requirement of a large quantity of V2X (vehicle-to-everything) services, the terminal may request the resource in the supplementary resource pool to transmit the sidelink data.

Abstract: Example communication methods and apparatus are described. One example communication method includes receiving signaling on a first carrier by a terminal device. The terminal device determines slot formats of N slots on at least one second carrier, where the slot formats of the N slots are determined based on M slot formats. N and M are positive integers. The M slot formats are obtained based on the received signaling, and the N slots are determined based on at least one of the following: a moment at which the signaling is received, and a relationship between a length of a first slot on the first carrier and a length of a second slot on the at least one second carrier. According to the communication method, the terminal device, and a network device in this application, slot formats of slots on a plurality of carriers can be determined.
