Centralized control sharing of spectrum for coexistence of wireless communication systems in unlicensed bands
First Claim
1. An apparatus, comprising:
- circuitry configured tocollect information about transmissions in an unlicensed frequency band, the collected information including user equipment mode preference and macro cell location;
select between a listen before transmit mode and a non-listen before transmit mode based on the collected information; and
inform at least one user equipment of the selected mode for use in the unlicensed frequency band by transmitting mode selection information in a Long Term Evolution-Advanced (LTE-A)-compliant system information block (SIB).

Abstract
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.
