Abstract
A base station operates according to a first radio access technology (RAT) that requires synchronization on timing synchronization boundaries. The base station acquires a channel of an unlicensed frequency band and generates a clear-to-send message that is decodable by access points that operate according to a second RAT that does not require synchronization on the timing synchronization boundaries. The base station transmits the clear-to-send message during a time interval between acquisition of the channel and a subsequent timing synchronization boundary.
