Abstract

An embodiment of the present invention provides a data transmission method, a network device, and a terminal. The data transmission method includes: the network device receives a first reference signal and a first physical channel sent by a first terminal device, wherein the first reference The signal is located in the ith symbol in a time slot, i is a positive integer less than 7, the first physical channel occupies n symbols in the time slot, and n is 1, or n is 2, or n is 3 ; The network device demodulates the first physical channel according to the first reference signal. The invention can reduce the time delay of data transmission.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission method, network equipment and terminal equipment. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is a technical standard formulated by the 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) organization. In the LTE system, the duration of a subframe is 1 ms, and each subframe is divided into two slots equally, and the duration of each slot is 0.5 ms. In an LTE system, a Transmission Time Interval (Transmission Time Interval, TTI) is a length of one subframe. [0003] In a wireless communication system, latency is one of the important factors affecting user experience. In the uplink transmission of the LTE system, after receiving the information of the Physical Uplink Share Channel (PDSCH for short), the base station needs to feed back the reception result to the terminal equipment after a certain period o...
