APPARATUS AND METHOD FOR DETERMINING TRANSMISSION DIRECTION OF SECONDARY CARRIER

摘要

Embodiments of the present invention provide an apparatus and method for determining a transmission direction of a secondary carrier. A reference carrier of a first secondary carrier is acquired according to network configuration information, and a transmission direction of a subframe in the first secondary carrier is determined according to a transmission direction of a subframe in the reference carrier, so that a data transmission direction of the reference carrier is the same as that of the first secondary carrier at a same time point. A data transmission direction of a subframe of a first secondary carrier transmitted in a neighboring frequency band of a reference carrier is determined according to the reference carrier; accordingly, it is ensured that the data transmission directions are the same when data is transmitted in the reference carrier and the first secondary carrier at the same time, thereby avoiding interference caused when data in different directions is transmitted in neighboring frequency bands.
