Problems solved by technology

Due to different transmission modes, the process of terminal equipment measuring CSI is different, and the process of feeding back the measured CSI to network equipment is also different. However, in the prior art, terminal equipment cannot determine whether the CSI process is an enhanced CSI process, that is, terminal equipment It is impossible to determine which transmission mode needs to measure and feed back CSI, and the terminal device cannot perform the process of measuring CSI and feedback of CSI
In the fifth generation (5G) system, for scenarios that support multiple transmission modes, there is currently no technical solution for terminal equipment to measure and feed back CSI

Embodiment Construction

[0118]Embodiments of the present application provide a communication method and device, which are used to measure CSI on a terminal device for a scenario supporting multiple transmission modes, and to feed back the measured CSI to a network device. Among them, the method and the device are based on the same inventive concept, and since the principles of the method and the device to solve the problem are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

[0119] The technical solution provided by the embodiment of the present application is applicable to the scenario where the transmission mode adopted between the terminal device and the network device supports multiple transmission modes, and the multiple transmission modes may include single-point transmission mode and coordinated multi-point transmission mode. Among them, the single-point transmission mode refers to supporting data transmission bet...

Abstract

The invention discloses a communication method and device. The method comprises the steps that a network device sends configuration information to a terminal device; the terminal device determines a channel state information (CSI) measurement behavior and / or CSI feedback related information, wherein the channel state information (CSI) measurement behavior and / or the CSI feedback related information is related to the configuration information; and the terminal device performs CSI measurement to acquire at least one piece of CSI according to the CSI measurement behavior and / or the CSI feedback related information and the configuration information, and sends all or part in the at least one piece of CSI to the network device. According to the method, for a scene in support of various transmission modes, the terminal device can measure the CSI and feeds back the measured CSI to the network device.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201710812735.8 and the application name "a communication method and device" submitted to the China Patent Office on September 11, 2017, the entire contents of which are incorporated in this application by reference. technical field [0002] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0003] Currently, the transmission mode adopted between the terminal device and the network device supports a single point transmission mode and a coordinated multiple points transmission / reception (CoMP) mode. The single-point transmission mode means that one transmission point independently completes the data transmission with one terminal device, and the multi-point cooperative transmission mode means that multiple geographically separated transmission points jointly complete the dat...
