Problems solved by technology

For the scenario where the NR system and the LTE system share the same uplink frequency band, the downlink transmission of the NR system cannot be synchronized with the uplink transmission, so that the terminal device cannot determine the number of the uplink subframe according to the number of the downlink subframe
[0005] It can be seen from the above that at least the following technical problems exist in the prior art: when the downlink transmission cannot be synchronized with the uplink transmission, the terminal device cannot obtain the number of the uplink subframe, resulting in the terminal device being unable to perform uplink transmission

Abstract

The embodiments of the present invention disclose an information transmitting method, an information receiving method, a network device and a terminal device. The invention aims to enable a terminal device to determine correct time for uplink transmission and avoid uplink transmission failure. According to one embodiment of the present invention, the method includes the following steps that: a network device determines first initial receiving time and first initial sending time, wherein the first initial receiving time is receiving time when the network device starts receiving signals in a first time period, and the first initial sending time is sending time when the network device starts sending signals in a second time period; the network device sends indication information to the terminal device, wherein the indication information is used to instruct the terminal device to determine second initial sending time, wherein the second initial sending time is determined according to the first initial receiving time and the first initial sending time.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an information sending method, a receiving method, network equipment, and terminal equipment. Background technique [0002] During the development and evolution of the wireless communication system, the New Radio interface (NR) system of the fifth-generation mobile communication technology (5th-Generation, 5G) can be deployed simultaneously on the frequency band below 6 gigahertz (GigaHertz, GHz). and Long Term Evolution (LTE) system. At present, the NR system is most likely to be deployed on the frequency point of 3.5GHz first, but considering that the uplink coverage of the NR system at this frequency point cannot match the downlink coverage, that is, the range of downlink coverage is significantly larger than the range of uplink coverage, making the NR system The uplink rate is limited. Since the uplink and downlink coverage of the LTE system at the 1.8G...
