Abstract
A mobile network comprises a cell, with one or more subordinate cells having regions that are each located at least partially within a coverage region of the cell. A base station serving the cell receives a measurement report from a further base station. The further base station is operable for serving one of the subordinate cells. The measurement report indicates a result of a measurement performed by the further base station on an uplink reference signal transmitted by a user equipment. On the basis of the measurement report, the base station controls activity of the subordinate cell.
Claims45
A method for cell management in a mobile network comprising a cell with one or more subordinate cells at least partially within a coverage region of the cell, the method comprising:
- a base station serving the cell receiving a measurement report from a further base station operable for serving one of the subordinate cells, the measurement report indicating a result of a measurement performed by the further base station on an uplink reference signal transmitted by a user equipment;
- and
- on the basis of the measurement report, the base station controlling activity of the subordinate cell.
A method for cell management in a mobile network comprising a cell with one or more subordinate cells at least partially within a coverage region of the cell, the method comprising:
- a base station operable for serving one of the subordinate cells performing a measurement on an uplink reference signal transmitted by a user equipment;
- the base station generating a measurement report indicating a result of the measurement;
- the base station sending the measurement report to a further base station serving the cell;
- and
- in response to the measurement report, the base station receiving information from the further base station for controlling activity of the subordinate cell.
A base station for a mobile network comprising a cell with one or more subordinate cells at least partially within a coverage region of the cell, the base station comprising:
- a radio interface for serving a user equipment in the cell;
- a further interface for communication with one or more further base stations operable to serve the subordinate cells;
- and
- at least one processor, the at least one processor being configured to:
- receive a measurement report from the further base station operable to serve one of the subordinate cells, the measurement report indicating a result of a measurement performed by the further base station on an uplink reference signal transmitted by a user equipment;
- and
- on the basis of the measurement report, control activity of the subordinate cell.

A base station for a mobile network comprising a cell with one or more subordinate cells at least partially within a coverage region of the cell, the base station comprising:
- a radio interface for serving a user equipment in one of the subordinate cells;
- a further interface for communication with a further base station serving the cell;
- and
- at least one processor, the at least one processor being configured to:
- perform a measurement on an uplink reference signal transmitted by a user equipment;
- generate a measurement report indicating a result of the measurement;
- send the measurement report to a further base station serving the cell;
- and
- in response to the measurement report, receive information from the further base station for controlling activity of the subordinate cell.
