Problems solved by technology

However, in order to obtain the beam with the strongest interference of each coordinated transmission point, when the number of coordinated TPs is large, the UE measurement complexity is greater, and the feedback overhead is also greater
Moreover, when measuring the serving cell and the coordinated cell, the measurement of the UE does not distinguish between the serving cell and the coordinated cell. For the servi

Abstract

The invention discloses a measuring method and device. According to the method and the device, the feedback overhead is saved, and meanwhile, a measurement result meets the demand of CoMP. The measuring method comprises the following steps that a first network device sends a restricted channel state information (CSI) measurement instruction to a second network device, wherein the restricted CSI measurement instruction is used for indicating the second network device to perform restricted CSI measurement; and the first network device receives CSI sent by the second network device, wherein the CSI is generated after the CSI measurement is completed according to the CSI measurement instruction.

Description

technical field [0001] The present invention relates to the field of communications, and more particularly, to methods and devices for measurement. Background technique [0002] Multiple-input multiple-output (MIMO) technology is considered to be one of the key technologies that can realize high-speed data transmission in the future, and has broad application prospects in fourth-generation and fifth-generation mobile communication systems. Multiple transmitting antennas of a traditional centralized MIMO system are concentrated at a base station (base station, BS) end. Different from the centralized MIMO system, the multiple transmitting antennas of the distributed MIMO system are distributed in different geographical locations, and each pair of transmitting and receiving links is more independent, with large capacity, low power consumption, better coverage, and low impact on the human body. Advantages such as electromagnetic damage are considered to be one of the options fo...
