COMPETITION METHOD AND APPARATUS FOR CHANNEL OF UNLICENSED FREQUENCY BAND

摘要

Embodiments of the present invention provide a method and system for contending for a channel of an unlicensed frequency band, and an apparatus. The method for contending for a channel of an unlicensed frequency band in the present invention includes: acquiring, according to contention timeslot configuration information, a condition for starting a contention timeslot, and starting the contention timeslot when the condition is met, where the contention timeslot configuration information includes at least one of the following configurations: a time configuration of the contention timeslot, a contention backoff time, a terminal feedback uplink configuration, or a channel available condition; and performing a corresponding operation within the contention timeslot according to the time configuration of the contention timeslot to contend for a channel of an unlicensed frequency band, so as to implement data transmission on the unlicensed frequency band. According to the embodiments of the present invention, data transmission is performed in an LTE carrier aggregation technology by using the unlicensed frequency band, so that an LTE user and another RAT user fairly and properly use unlicensed spectrum resources, and a mutual interference problem is resolved.
