Abstract
In a heterogeneous cellular communication network, a macro cell equipped with a base station may be configured to support one or more macro user equipment (UE) and one or more micro cells, each of which further serves as proxies of one or more micro UE for wireless communications between the micro UE and the macro cell. The base station may be configured to assign a first cell ID to the macro cell and other cell IDs that have a mathematical distinction from the first cell ID to the micro cells.
Claims25
A wireless communication system in a heterogeneous network, the wireless communication system comprising:
- a macro cell that comprises a base station and at least one low power node communicatively coupled to the base station;
- and
- a cell identifier (ID) allocator configured to:
- identify a series of numeric values as multiple candidate cell IDs;
- allocate a first cell ID, from the multiple candidate cell IDs, for the macro cell;
- determine a mathematical trait, for each of the multiple candidate cell IDs, by calculation of a remainder of a division of the respective candidate cell ID by a particular number;
- allocate a second cell ID for the at least one low power node based on the determined mathematical trait, wherein the second cell ID is mathematically distinct from the first cell ID;
- and
- configure the at least one low power node and the macro cell to respectively use the allocated first and second cell IDs to operate the wireless communication system.
A method performed by a base station in a wireless communication system, the method comprising:
- identifying a series of numeric values as multiple candidate cell IDs;
- allocating a first cell ID, from the multiple candidate cell IDs, for a macro cell;
- determining a mathematical trait, for each of the multiple candidate cell IDs, by calculating a remainder of a division of the respective candidate cell ID by a particular number;
- allocating a second cell ID for at least one low power node based on the determined mathematical trait, wherein the second cell ID is mathematically distinct from the first cell ID;
- and
- configuring the macro cell and the at least one low power node to respectively use the allocated first and second cell IDs to operate the wireless communication system.
