Problems solved by technology

However, the method of increasing the measurement bandwidth cannot solve the problem of poor CSI-RS RSRP measurement accuracy when the system bandwidth is limited, and the method of increasing the measurement time cannot completely eliminate the impact of too small number of samples in the subframe on the measurement accuracy
In addition, these

Abstract

The application provides a method for measuring and reporting the receiving power or receiving quality of a channel reference signal through multiple channel reference signal resources. The method comprises the following steps: signaling is received by user equipment, wherein the signaling is used to indicate multiple channel reference signal resource combinations to the measurement of the channel reference signal receiving power and/or receiving quality and respective configuration information thereof; resource positions of the multiple channel reference signal resource combinations and respective configuration information thereof are acquired by the user equipment from the signaling; and the user equipment is used to measure the channel reference signal on the corresponding resource position and report the measurement result. The invention further provides user equipment. Through the scheme provided in the application, when the UE maintains reasonable complexity and power consumption, the measurement accuracy of the channel reference signal receiving power or receiving quality measured by the UE can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular, the present application relates to a method and device for measuring a channel reference signal. Background technique [0002] For the LTE system, coordinated multi-point operation (CoMP) is an important feature, and the coordinated multi-point operation can effectively improve the peak rate of the system and the throughput of users at the cell edge. [0003] In order to ensure that the user equipment (UE) can obtain correct configuration and feed back effective channel quality information during the moving process, it is necessary to effectively manage the CoMP channel information measurement set. In order to effectively manage the CoMP channel information measurement set of the user equipment, the user equipment needs to measure and report the received power (CSI-RS RSRP) of the channel reference signal. The CSI-RS RSRP is the received power of the c...
