Abstract

This application provides a physical channel sending method, receiving method, terminal equipment and network equipment. The physical channel sending method includes: a terminal device generates a physical channel, the physical channel is composed of N physical channel units, and N is a positive integer; the terminal device sends the physical channel in a first time domain resource; Wherein, the first time domain resource includes M time intervals, the N physical channel units are located on N time intervals in the M time intervals, and M is a positive integer greater than or equal to N. By adopting the method and wireless communication device provided in this application, wireless resources can be effectively multiplexed, thereby reducing the waste of wireless resources.

Description

technical field [0001] The present application relates to the field of wireless communication, in particular to a physical channel sending method, a receiving method, terminal equipment and network equipment. Background technique [0002] In a wireless communication system, latency is one of the important factors affecting user experience. New services that continue to emerge, such as services related to the Internet of Vehicles, also put forward higher and higher requirements for latency. Therefore, in the existing long term evolution (longterm evolution, LTE for short) system, a transmission mechanism based on a transmission time interval (transmission time interval, TTI for short) of one subframe cannot meet the requirements of low-latency services. In order to reduce the delay, the TTI length of the physical downlink shared channel (PDSCH for short), the physical uplink shared channel (PUSCH for short) and the physical uplink control channel (PUCCH for short) needs to b...
