Abstract:
1. A method of allocating a resource in wireless communication system, the method comprising: periodically receiving, by a coexistence discovery and information server (CDIS) entity, at least one available resource from a TV database (TVDB) entity, wherein an Access Point (AP) entity registers the TVDB entity and at least one Coexistence Manager (CM) entity, and wherein the AP entity requests the at least one resource from the at least one CM entity before CDIS entity periodically receives the at least one available resource form the TVDB entity; performing, by the CDIS entity, a neighbor set calculation based on the received at least one available resource in order to calculate a neighbor of the at least one coexistence manager (CM) entity so as to determine a neighbor of the at least one CM entity; calculating, by the CDIS entity, a resource for at least one TV band device (TVBD) according to the neighbor set calculation, wherein the resource for the at least one TVBD is calculated by the CDIS entity by making a coexistence whitespace map (CWM) based on the neighbor set calculation; and notifying, by the CDIS entity, the neighbor set calculation and the calculated resource to the at least one CM entity, wherein the at least one CM entity allocates the resource to the at least one TVBD based on the neighbor set calculation and the calculated resource, wherein the neighbor set is recalculated and a final resource is allocated to the TVBD entity after a negotiation by the at least one CM entity.
