Method and system for joint coordination and coexistence in unlicensed spectrum

摘要

A method and system at a network element for providing a soft airtime share of unlicensed spectrum to at least one transmission point. The method includes receiving, from a plurality of transmission points, sensing results, selecting a group of candidate channels, grouping subsets of transmission points into radio access clusters, receiving, from each radio access cluster, a report, and allocating a soft airtime share to a radio access cluster for a channel at a time. Also, at a transmission point, a method and system for obtaining a soft airtime share of a channel in unlicensed spectrum. The method includes sensing a plurality of channels, providing a report, receiving a message assigning at least one radio access cluster, contending with other radio access clusters to send a beacon, receiving coordination beacons from neighboring clusters, self-scheduling and reporting in accordance with the received coordination beacons, and receiving an airtime share.

1. A method at a transmission point for obtaining resources of a channel in an unlicensed spectrum band, the method comprising:
Performing sensing on a plurality of channels; providing a report to a network element in accordance with results of the sensing; receiving a message providing at least one radio access cluster for the transmission point per channel; contending, on behalf of the at least one radio access cluster, with other radio access clusters to send a coordination beacon on a channel; receiving coordination beacons from neighboring radio access clusters on the channel; reporting information from the coordination beacons to the network element; and receiving an allocation of resources for the channel.
