Abstract

The invention discloses a method and apparatus for measuring an uplink channel. The method comprises the following steps: a transmission node TP configures Cluster CSI process information for a mobileterminal UE based on measurement information reported by the UE, wherein the Cluster CSI process information is used for measuring a group of determined TP channel information from the UE to the TP;nd the TP triggers the UE to perform measurement report, so that the UE measures and reports uplink channel information according to the Cluster CSI process information. The invention provides a new channel measurement configuration method, which can be applicable to a multi-point transmission scene and can maximally support the flexibility of TP scheduling.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a method and device for measuring an uplink channel. Background technique [0002] Channel measurement is the basis for efficient and reliable transmission of wireless communication. It enables the transmitter to adjust the channel input signal to make better use of the channel capacity, such as adjusting the beamforming vector of the transmitter so that the signal can be better aligned to the target receiving point. In cellular communication, the transmission node TP performs flexible multi-user scheduling through channel information obtained by measurement or feedback, thereby achieving multi-user diversity gain, which is beneficial to improving system capacity. [0003] In the current LTE system, the measurement of the downlink channel adopts the configuration of CSI-process, so that the UE measures the designated reference signal and interferenc...
