Abstract: Coexistence gaps may permit one radio access technology (RAT) to coexists with another RAT by providing period in which one RAT may be silent and another may transmit. Methods may account for the RAT traffic and for the presence of other secondary users in a channel. Methods may be provided to dynamically change the parameters of a coexistence gap pattern, such as the duty cycle, to adapt to both the RAT traffic and the presence of other secondary users. Methods may include PHY methods, such as synchronization signal (PSS/SSS) based, MIB based, and PDCCH based, MAC CE based methods, and RRC Methods. Measurements may be provided to detect the presence of secondary users, and may include reporting of interference measured during ON and OFF durations, and detection of secondary users based on interference and RSRP/RSRQ measurements.
