Abstract
A method for a small cell access point to use neighbour cell broadcast information to derive a cell candidate list is described. The method comprises, at the small cell access point: performing a network listen, NWL, scan and identifying a broadcast transmission from a plurality of macro cell base station, BTSs; detecting at least one parameter from each broadcast transmission, wherein the at least one parameter acts as a signature for small cell neighbours to distinguish small cell neighbours from macro cell neighbours; and using the at least one parameter to derive a cell candidate list of candidate operating parameters.

A method for a small cell access point to use broadcast information to derive a cell candidate list from a neighbour cell list, the method comprising, at the small cell access point:
- performing a network listen, NWL, scan and identifying a broadcast transmission from a plurality of macro cell base station, BTSs;
- detecting at least one parameter from each broadcast transmission by identifying a Qoffset parameter from decoding a first system information block, SIB, message that provides information about each macro cell BTS's neighbouring macro and small cells to determine neighbour information and network cell reselection parameters, wherein the at least one parameter acts as a signature for small cell neighbours to distinguish small cell neighbours from macro cell neighbours by;
- comparing the detected at least one Qoffset parameter with a first threshold value;
- and
- identifying therefrom whether the at least one Qoffset parameter indicates a macro cell or a small cell when deriving a cell candidate list of candidate operating parameters;
- and
- using the at least one parameter to derive a cell candidate list of candidate operating parameters.
A small cell base station is configured to use broadcast information to derive a cell candidate list from a neighbour cell list, the small cell base station comprises:
- a transceiver, and
- a signal processor operably coupled to the transceiver and configured to:
- perform a network listen, NWL, scan and identify a broadcast transmission from a plurality of macro cell base station, BTSs;
- detect at least one parameter from each broadcast transmission by identifying a Qoffset parameter from decoding a first system information block, SIB, message that provides information about each macro cell BTS's neighbouring macro and small cells to determine neighbour information and network cell reselection parameters, wherein the at least one parameter acts as a signature for small cell neighbours to distinguish small cell neighbours from macro cell neighbours by;
- compare the detected at least one Qoffset parameter with a first threshold value;
- and
- identify therefrom whether the at least one Qoffset parameter indicates a macro cell or a small cell when deriving a cell candidate list of candidate operating parameters;
- and
- use the at least one parameter to derive a cell candidate list of candidate operating parameters.
