IMPROVED CONTROL OF TRANSMISSION IN COEXISTING WIRELESS COMMUNICATIONS SYSTEMS

摘要

. A telecommunications system that comprises a first radio system transceiving in all or part of a first frequency range, a second radio system managing all or part of a second frequency range. The first frequency range and the second frequency range overlap at least partly, and the overlapping parts form an intersected frequency zone. A network node (116) of the first radio system sends information on carrier application status of carrier in the intersected frequency range to a network node (120) of the second radio system that uses the information to control transmissions in one or more carrier frequency bands of the intersected frequency range.
