Inter-operator radio resource sharing in dense deployments of small cell networks
Methods and apparatus, including computer program products, are provided resource sharing. In some example embodiments, there may be provided a method, which may include receiving information including location information for at least one cell of a primary resource group, and further including a primary resource being used by the at least one cell; and determining at least one secondary resource group based on the received information. Related apparatus, systems, methods, and articles are also described.
1. A method comprising:
receiving, at a resource control node, information including location information for at least one cell of a primary resource group and another cell of another primary resource group, wherein the received information further includes a primary resource being used by the at least one cell and another primary resource being used by the other cell; and
determining, by the resource control node, at least one secondary resource group including the at least one cell and the other cell, wherein the at least one secondary group is determined based on the received information and a determination of an overlapping coverage area between the at least one cell and the other cell, wherein the at least one cell and the other cell are enabled to share, as part of the determined at least one secondary resource group, the primary resource.
2. The method of claim 1 , wherein the at least one cell and the other cell share, as a secondary resource, the primary resource.
3. The method of claim 1 , wherein the primary resource comprises at least one of a frequency or a time.
4. The method of claim 1 , wherein the primary resource group and the other primary resource group have a non-overlapping coverage area.
5. The method of claim 1 , wherein the at least one cell of the primary resource group is in a first mobile network, and the other cell of the other primary resource group is in a second mobile network.
6. The method of claim 5 , wherein the first mobile network signals the second mobile network to form the at least one secondary resource group by at least requesting the information including the location information and the primary resource.
7. The method of claim 6 , wherein the first mobile network is operated by a network operator different than the second mobile network.
8. The method of claim 1 , wherein the at least one cell and/or the other cell each comprise a small cell.
9. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
receive, at the apparatus, information including location information for at least one cell of a primary resource group and another cell of another primary resource group, wherein the received information, further includes a primary resource being used by the at least one cell and another primary resource being used by the other cell; and
determine, by the apparatus, at least one secondary resource group including the at least one cell and the other cell, wherein the at least one secondary group is determined based on the received information and a determination of an overlapping coverage area between the at least one cell and the other cell, wherein the at least one cell and the other cell are enabled to share, as part of the determined at least one secondary resource group, the primary resource.
10. The apparatus of claim 9 , wherein the at least one cell and the other cell share, as a secondary resource, the primary resource.
11. The apparatus of claim 9 , wherein the primary resource comprises at least one of a frequency or a time.
12. The apparatus of claim 9 , wherein the primary resource group and the other primary resource group have a non-overlapping coverage area.
13. The apparatus of claim 9 , wherein the at least one cell of the primary resource group is in a first mobile network, and the other cell of the other primary resource group is in a second mobile network.
14. The apparatus of claim 13 , wherein the first mobile network signals the second mobile network to form the at least one secondary resource group by at least requesting the information including the location information and the primary resource.
15. The apparatus of claim 9 , wherein the apparatus comprises a resource control node.
