Centralized control sharing of spectrum for coexistence of wireless communication systems in unlicensed bands

摘要

In one embodiment information is received from one or more wireless networks indicating a request for a listen before transmit mode or a non-listen before transmit mode. In reply it is determined whether the one or more wireless networks is to utilize the listen before transmit mode or the non-listen in an unlicensed frequency band and the one or more wireless networks are informed of the determined mode. Centralized control of spectrum for coexistence of wireless communication systems in unlicensed bands according to exemplary embodiments of the invention can be performed by an enhanced coexistence manager or a network access node with information obtained from one or more base stations or user equipment.
