Method and device for measuring channel reference signal

Abstract

The present application proposes a method for measuring and reporting the received power or quality of a channel reference signal by using multiple channel reference signal resources, including the following steps: the user equipment receives a signaling indicating to measure the received power of a channel reference signal and / or the multi-channel reference signal resource combination corresponding to the reception quality and its corresponding configuration information; the user equipment obtains the resource location corresponding to the multi-channel reference signal resource combination and its corresponding configuration information from the signaling; The channel reference signal is measured at the resource position, and the measurement result is reported. The present invention The present application also proposes a user equipment. The above solution proposed in this application effectively improves the measurement accuracy of the channel reference signal received power or received quality measured by the UE under the condition that the UE maintains a reasonable complexity and power consumption.

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...

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 two methods will also increase the implementation complexity of the user equipment and increase the power consumption of the user equipment

[0007] Therefore, it is necessary to find a technical solution that can effectively solve the problem of insufficient CSI-RS RSRP measurement accuracy and is not limited by the system measurement bandwidth.
