US 2026/0312753 A1 · COMMUNICATION METHOD AND APPARATUS

Abstract

This application provides a communication method and apparatus, relating to the field of wireless communication technologies. The method includes a network device sending first configuration information, where the first configuration information indicates a first downlink carrier, a first uplink carrier, and a second uplink carrier. The first downlink carrier is for downlink data transmission, and the first uplink carrier and the second uplink carrier are for uplink data transmission. The first downlink carrier and the first uplink carrier are respectively for downlink data transmission and uplink data transmission in TDD mode. The first downlink carrier, the first uplink carrier, and the second uplink carrier are located within a first band. Based on the first configuration information, the network device performs data transmission with a terminal device by using at least one of the first downlink carrier, the first uplink carrier, and the second uplink carrier.
