Problems solved by technology

[0004] Therefore, if the terminal device directly uses the received signal to perform channel estimation, channel detection, or data demodulation after receiving the signal on the time-frequency resource of the transmission reference signal, the performance of channel estimation, channel detection, or data demodulation will be reduced. reliability

Abstract

The present invention provides a communication method, a terminal device, and a network device. The method includes the following steps that: a terminal device receives first indication information sent by a network device, wherein the first indication information is used to indicate a first time frequency resource for transmitting the reference signals of the terminal device; the terminal devicereceives second indication information sent by the network device, wherein the second indication information is used to indicate a second time-frequency resource; and the terminal device determines whether a third time-frequency resource is included in the first time-frequency resource according to the second indication information, wherein the third time-frequency resource is a time-frequency resource included in the first time-frequency resource and the second time-frequency resource, or a time-frequency resource adjacent to the second time-frequency resource, a time-frequency resource of which the interval with the second time-frequency resource is smaller than a preset first interval, or a time-frequency resource related to the second time-frequency resource. Therefore, the terminal device can further determine whether to use signals on the third time-frequency resource.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a communication method, a terminal device and a network device. Background technique [0002] Reference signal (Reference Signal, RS), also known as "pilot signal". In the Long Term Evolution (LTE) system, after receiving the reference signal on the time-frequency resource for transmitting the reference signal, the terminal device will directly use the reference signal to achieve channel estimation, channel detection or data demodulation and other purposes. [0003] However, in the 5G communication system, there are many different types of services, and different types of services require different transmission requirements. In order to meet the transmission requirements of different types of services, there will be interference or resource preemption. For example, when a network device transmits data of an enhanced mobile broadband (eMBB) service, data of an ultra r...
