<p>Embodiments of the present invention disclose a method, an apparatus, and a system for correcting a receiving and sending channel response. The method includes: taking, by a first baseband module, a first receiving and sending channel as a reference correction channel in a first radio frequency module, and correcting a channel response ratio of each receiving and sending channel in the first radio frequency module, so that the channel response ratio of each receiving and sending channel in the first radio frequency module is consistent with a channel response ratio of the first receiving and sending channel; and taking, by the first baseband module, the first receiving and sending channel and a second receiving and sending channel as correction channels of the first radio frequency module and a second radio frequency module, and correcting a channel response ratio of the second receiving and sending channel, so that the channel response ratio of the second receiving and sending channel is consistent with the channel response ratio of the first receiving and sending channel. Correction on channel responses of receiving and sending channels of coordinated radio frequency modules is implemented by applying the embodiments of the present invention, so that when the coordinated radio frequency modules transmit downlink signals to a UE, channel response ratios of the receiving and sending channels of the different radio frequency modules are the same, so signal quality may be improved when signals are sent through inter-cell coordination, thereby improving JT performance of the system.</p> |
