Japanese Patent JP6702605
Kind Code:
B2
Abstract:
Embodiments of this application provide a channel correction method, used for performing channel correction on radio frequency apparatuses in a network area, where the radio frequency apparatuses in the network area are divided into at least one radio frequency apparatus group, each radio frequency apparatus group includes a plurality of radio frequency apparatuses, configuration information is preset on a base station where a first radio frequency apparatus is located, where the configuration information is used to indicate a resource location where each radio frequency apparatus in a radio frequency apparatus group to which the first radio frequency apparatus belongs sends a correction signal, and the first radio frequency apparatus is any radio frequency apparatus in the network area; and the method is performed by the base station where the first radio frequency apparatus is located and includes: controlling, based on the configuration information in a correction cycle, the first radio frequency apparatus to send a first correction signal at a first resource location, and receiving a first received signal, corresponding to the first correction signal, from a second radio frequency apparatus, where the first resource location is a resource location where the first radio frequency apparatus sends the correction signal, and the second radio frequency apparatus is a radio frequency apparatus in the radio frequency apparatus group to which the first radio frequency apparatus belongs; obtaining, based on the configuration information in the correction cycle, a second received signal at a second resource location through the first radio frequency apparatus, where the second received signal is corresponding to a second correction signal, and the second resource location is a resource location where the second radio frequency apparatus sends the second correction signal; and compensating a channel of the first radio frequency apparatus based on the first correction signal, the second correction signal, the first received signal, and the second received signal. The method can implement joint channel correction for a plurality of radio frequency apparatuses and improve correction efficiency.
