JOINT CHANNEL CORRECTION METHOD, JOINT CHANNEL CORRECTION UNIT AND BASE STATION

摘要

Embodiments of the present invention provide a joint channel correction method, a joint channel correction unit and a base station. The joint channel correction method can implement joint channel correction between base stations in a base station set. At least one base station in the base station set is connected to the joint channel correction unit, so that all base stations in the base station set share a common reference transmit end and a common reference receive end.

主权项

1. A joint channel correction method used for joint channel correction between base stations in a base station set, wherein the base station set comprises at least two base stations, and at least one base station in the base station set is connected to a joint channel correction unit, so that all the base stations in the base station set share a common reference transmit end and a common reference receive end; and
the method comprises: sending, by the common reference transmit end, an uplink correction signal to each base station in the base station set, wherein the uplink correction signal is used to calculate an uplink channel estimation value of each base station; receiving, by the common reference receive end, a downlink correction signal sent by each base station in the base station set, wherein the downlink correction signal is used to calculate a downlink channel estimation value of each base station; and completing channel self-correction of each base station according to the uplink channel estimation value and the downlink channel estimation value of each base station.
