Embodiment Construction

[0125] The technical solution in this application will be described below with reference to the accompanying drawings.

[0126] The terms "component", "module", "system" and the like are used in this specification to refer to a computer-related entity, hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and / or a computer. By way of illustration, both an application running on a computing device and the computing device can be components. One or more components can reside within a process and / or thread of execution and a component can be localized on one computer and / or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon. A component may, for example, b...

Abstract

The present application provides a method and device for transmitting reference signals. The method comprises the following steps: a network device sends first indication information to a terminal device, wherein the first indication information indicates the first configuration information of at least two types of configuration information corresponding to a first demodulation reference signal; each of the at least two types of configuration information comprises at least one of the following parameters: a sequence used for demodulating a reference signal, a density of time-frequency resources carrying the demodulated reference signal within a time-frequency resource group, an antenna port associated with the demodulated reference signal, and a location of the time-frequency resources carrying the demodulated reference signal. According to the first configuration information, the network device transmits the first downlink information and the first demodulation reference signal to theterminal device through the first time-frequency resource group, and the first demodulation reference signal is used for demodulating the first downlink information. Thus, it is possible to meet theconfiguration requirements of the reference signal for services having different reliability requirements.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on June 16, 2017, with the application number 201710459603.1, and the title of the application is "Method and device for sending reference signals and method and device for receiving reference signals", all of which The contents are incorporated by reference in this application. technical field [0002] The present application relates to field communication, and more particularly, to a method and apparatus for transmitting a reference signal and a method and apparatus for receiving a reference signal. Background technique [0003] At present, reference signals have been widely used. In the process of using the reference signal in the prior art, the sending end device sends the demodulation reference signal while sending the data, and the receiving end device first performs channel estimation according to the demodulation reference signal, and further demodulates...
