Abstract
A mobile communications system is proposed in which mobile communications devices are arranged to carry out signal measurements on the signals received from neighboring cells. The bandwidth over which these signal measurements are carried out is determined in dependence upon the bandwidths of the neighboring cells and is signalled to the mobile communication device by a serving base station.
Claims33
A method performed by a base station of a communication network, the method comprising:
- obtaining cell bandwidths of neighbouring cells;
- determining a smallest bandwidth from amongst the obtained cell bandwidths;
- and
- signalling a measurement bandwidth to a mobile communications device in dependence upon the determined smallest bandwidth.
A method performed in a mobile communications device, the method comprising:
- receiving signalling information from an associated communications device, the signalling information identifying a measurement bandwidth determined using at least one of a smallest bandwidth of neighbouring cells and a bandwidth of a cell serving the mobile communications device;
- detecting neighbouring cells;
- and
- performing measurements on the signals from the neighbouring cells over the bandwidth identified by the signalling information.
A base station, comprising:
- means for obtaining cell bandwidths of neighbouring cells;
- means for deteimining a smallest bandwidth from amongst the obtained cell bandwidths;
- and
- means for signalling a measurement bandwidth to a mobile communications device in dependence upon the determined smallest bandwidth.
A mobile communications device, comprising:
- means for receiving signalling information from an associated communications device, the signalling information identifying a measurement bandwidth deteimined using at least one of a smallest bandwidth of neighbouring cells and a bandwidth of a cell serving the mobile communications device;
- means for detecting neighbouring cells;
- and
- means for performing measurements on the signals from the neighbouring cells over the bandwidth identified by the signalling information.
