Abstract
A method of operating a target terminal being serviced by a serving base station is provided. In a downlink case, the target terminal being served by the serving base station may provide a feedback message to a neighboring base station. The feedback message may be used by the neighboring base station to verify channel information between the serving base station and the target terminal, and channel information between the neighboring base station and the target terminal. In an uplink case, the neighboring base station may provide the feedback message to the target terminal. The target terminal may transfer, to the serving base station, channel information between the neighboring base station and a particular terminal, and channel information between the neighboring base station and the target terminal that are verified based on the feedback message. The feedback message may be transferred using a common shared channel or a random access channel.
