A method, comprising: receiving (501, 502), from a local scheduler in a first base station, access network information at a global scheduler, the access network information including at least one of channel usage information, signal strength information, interference information, or neighbor status information; accessing information regarding a second base station; allocating, at the global scheduler, based on the information regarding the second base station and the access network information, a set of resources for local allocation by the local scheduler, the second base station being a neighbor of the first base station or a neighbor of a neighbor of the first base station; applying by the global scheduler a hash function on the allocated set of resources for local allocation, to map the set of resources for local allocation to a set of hash values configured to enable identification of the set of resources for local allocation by the local scheduler at the first base station and by a second local scheduler at the second base station, wherein the global scheduler is configured to query an existing TeleVision White Space, TVWS, database and to use results of the query when performing scheduling, wherein a base station that is capable of using the TVWS is assigned a hash value corresponding to a TVWS frequency that is available, and wherein hash calculation and distribution frequency are dependent on X2 protocol link latency or any other link latency, and/or traffic conditions on a backhaul network, and/or load and congestion on the access network; and sending, from the global scheduler, the set of hash values to the first base station and scheduling use of resource blocks by the local scheduler, wherein the set of hash values comprises scheduling hints, access lists, exclusion lists, or handover predictions for the local scheduler. receiving (501, 502), from a local scheduler in a first base station, access network information at a global scheduler, the access network information including at least one of channel usage information, signal strength information, interference information, or neighbor status information; accessing information regarding a second base station; allocating, at the global scheduler, based on the information regarding the second base station and the access network information, a set of resources for local allocation by the local scheduler, the second base station being a neighbor of the first base station or a neighbor of a neighbor of the first base station; applying by the global scheduler a hash function on the allocated set of resources for local allocation, to map the set of resources for local allocation to a set of hash values configured to enable identification of the set of resources for local allocation by the local scheduler at the first base station and by a second local scheduler at the second base station, wherein the global scheduler is configured to query an existing TeleVision White Space, TVWS, database and to use results of the query when performing scheduling, wherein a base station that is capable of using the TVWS is assigned a hash value corresponding to a TVWS frequency that is available, and wherein hash calculation and distribution frequency are dependent on X2 protocol link latency or any other link latency, and/or traffic conditions on a backhaul network, and/or load and congestion on the access network; and wherein the global scheduler is configured to query an existing TeleVision White Space, TVWS, database and to use results of the query when performing scheduling, wherein a base station that is capable of using the TVWS is assigned a hash value corresponding to a TVWS frequency that is available, and wherein hash calculation and distribution frequency are dependent on X2 protocol link latency or any other link latency, and/or traffic conditions on a backhaul network, and/or load and congestion on the access network; and sending, from the global scheduler, the set of hash values to the first base station and scheduling use of resource blocks by the local scheduler, wherein the set of hash values comprises scheduling hints, access lists, exclusion lists, or handover predictions for the local scheduler.
