Abstract
A wireless communication network includes an apparatus and method for dynamically allocating frequencies of a femto Base Station (BS). An operation of the femto BS includes measuring received signal strength on system Frequency Allocations (FAs) of a plurality of macro BSs, determining maximum received signal strengths for the respective FAs, and determining an available FA set by using a result obtained from comparison between the maximum received signal strengths for the respective FAs with a first threshold.
Claims32
A method for an operation of a femto Base Station (BS) in a wireless communication system, the method comprising:
- measuring received signal strength on system Frequency Allocations (FAs) of a plurality of macro BSs;
- determining maximum received signal strengths for the respective FAs;
- and
- determining an available FA set by using a result obtained from comparison between the maximum received signal strengths for the respective FAs with a first threshold.
A method for an operation of a Network Management System (NMS) in a wireless communication system, the method comprising:
- receiving available Frequency Allocation (FA) sets of respective femto Base Stations (BSs);
- and
- determining an FA to be initially used by a first femto BS among at least one FA included in an available FA set of the first femto BS.
An apparatus for a femto Base Station (BS) in a wireless communication system, the apparatus comprising:
- a measurer configured to measure received signal strength on system Frequency Allocations (FAs) of a plurality of macro BSs;
- and
- a controller configured to determine maximum received signal strengths for the respective FAs and for determining an available FA set by using a result obtained from comparison between the maximum received signal strengths for the respective FAs with a first threshold.
An apparatus for a Network Management System (NMS) in a wireless communication system, the apparatus comprising:
- a communicator configured to receive available Frequency Allocation (FA) sets of respective femto Base Stations (BSs);
- and
- a controller configured to determine an FA to be initially used by a first femto BS among at least one FA included in an available FA set of the first femto BS.
