Description

Communication method and device, terminal equipment and network equipment Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus, a terminal device, and a network device. Background Half Duplex (HD) is a communication mode that reduces device cost and power consumption by simplifying the rf design. For example, half-duplex devices can only transmit or receive data at a certain time without requiring complex radio frequency hardware to support simultaneous transmission and reception of signals, thereby reducing the design complexity, cost, and power consumption of the half-duplex device. In a wireless communication network, a half-duplex terminal device cannot perform two communication processes of downlink (downlink) reception and uplink (uplink) transmission with a network device at the same time, which means that the half-duplex terminal device needs to perform downlink reception and uplink transmission alternately in a time division manner. However, when the downlink and the uplink overlap in time (overlap), further research is still required on whether the half-duplex terminal device performs downlink reception or uplink transmission. Disclosure of Invention The application provides a communication method and device, a terminal device and a network device, which are used for expecting to realize that half-duplex equipment performs one of downlink receiving or uplink transmission according to the priority level between downlink and uplink when the downlink and the uplink are overlapped in time.
