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.
Claims20
A wireless communication system in a heterogeneous network, comprising:
- a macro cell in which wireless communications are hosted for a first set of mobile devices and multiple low power nodes that serve as proxies for a second set of mobile devices;
- and
- a cell ID allocator configured to:
- identify a series of numeric values as multiple candidate cell IDs,
- randomly select a first cell ID, from the multiple candidate cell IDs, for the macro cell,
- identify a subset of the multiple candidate cell IDs associated with the first cell ID, and
- allocate a cell ID for each of the multiple low power nodes that has a mathematical distinction from the identified subset of the multiple candidate cell IDs.
A method for allocating resources for wireless communication system in a heterogeneous network, comprising:
- identifying a macro cell and multiple low power nodes;
- identifying a series of numeric values as multiple candidate cell IDs;
- randomly selecting a first cell ID, from the multiple candidate cell IDs, for the macro cell;
- identifying a subset of the multiple candidate cell IDs associated with the first cell ID;
- and
- allocating a cell ID for each of the multiple low power nodes that has a mathematical distinction from the identified subset of the multiple candidate cell IDs.
A computer-readable medium that stores executable-instructions that, when executed, cause one or more processors to perform operations comprising:
- identifying a macro cell and multiple low power nodes;
- identifying a series of numeric values as multiple candidate cell IDs;
- calculating, for each of the multiple candidate cell IDs, a remainder of division of the candidate cell ID by a predetermined number;
- randomly selecting a first cell ID, from the multiple candidate cell IDs, for the macro cell;
- dividing the multiple candidate cell IDs into a number of groups that is equal to the predetermined number;
- identifying, from the number of groups, a subset of the multiple candidate cell IDs associated with the first cell ID;
- and
- allocating a cell ID for each of the multiple low power nodes that is mathematically distinct from the identified subset of the multiple candidate cell IDs.
