Abstract
Cells are designated as neighbor cells to at least one radio unit (RU) in a managed cell based on signal power measurements provided by user equipment served by the at least one radio unit. A list is generated that includes each of the RUs in the managed cell and the neighbor cells that are associated with one or more of the RUs. A wireless system can perform one or more operating functions, including carrier aggregation and intra-inter-frequency handover, inter-RAT handover and IMS Voice/Emergency Call Fallback, based on the generated list.

A method for operating a wireless system, the wireless system including a baseband unit entity communicatively coupled to a plurality of radio units, the plurality of radio units configured to provide wireless service to user equipment located in at least one managed cell configured to be managed by the baseband unit entity, comprising:
- at each of the plurality of radio units, receiving signal power measurements corresponding to at least one cell, wherein the signal power measurements include a signal power of the at least one cell and are associated with a radio unit of the plurality of radio units;
- and
- for each of the plurality of radio units, designating the at least one cell as a neighbor cell for the radio unit of the plurality of radio units in the at least one managed cell based on the signal power measurements;
- generating a list including each of the plurality of radio units and each neighbor cell associated with the radio unit of the plurality of radio units in the at least one managed cell;
- and
- performing one or more operating functions of the wireless system based on the generated list.
A program product comprising a non-transitory processor-readable medium on which program instructions configured to be executed by at least one processor are embodied, wherein when executed by the at least one processor, the program instructions cause the at least one processor to:
- at each of the plurality of radio units, receive signal power measurements corresponding to at least one cell, wherein the signal power measurements include a signal power of the at least one cell and are associated with a radio unit of a plurality of radio units in at least one managed cell of a wireless system;
- for each of the plurality of radio units, designate the at least one cell as a neighbor cell for the radio unit of a plurality of radio units in the at least one managed cell based on the signal power measurements;
- generate a list including each of the plurality of radio units and each neighbor cell associated with the radio unit of the plurality of radio units in the at least one managed cell;
- and
- perform one or more operating functions of the wireless system based on the generated list.
A unit of a wireless system configured to provide wireless service to user equipment in at least one managed cell, the unit comprising:
- a network interface configured to receive wireless communication signals from a communication network;
- circuitry coupled to the network interface and configured to generate downlink signals from the wireless communication signals;
- a downlink interface coupled to the circuitry and configured to provide the downlink signals to a plurality of radio units communicatively coupled to the unit for transmission to the user equipment in the at least one managed cell;
- and
- at least one processor coupled to the downlink interface, wherein the at least one processor is configured to:
- at each of the plurality of radio units, receive signal power measurements corresponding to at least one cell, wherein the signal power measurements include a signal power of the at least one cell and are associated with a radio unit of a plurality of radio units in the at least one managed cell;
- for each of the plurality of radio units, designate the at least one cell as a neighbor cell for the radio unit of the plurality of radio units in the at least one managed cell based on the signal power measurements;
- and
- generate a list including each of the plurality of radio units and each neighbor cell associated with the radio unit of the plurality of radio units in the at least one managed cell;
- and
- perform one or more operating functions of the wireless system based on the generated list.
