Abstract
A measuring node, a controlling node and methods for controlling and/or using lean carrier operation with configurable control channel monitoring are disclosed. The method includes determining a presence of at least one user equipment operating based on a configurable control channel monitoring, and controlling a bandwidth based on the determining the presence of at least one user equipment operating based on a configurable control channel monitoring.
Claims35
A method for a controlling node, the method comprising:
- determining a presence of at least one user equipment operating based on a configurable control channel monitoring;
- and
- controlling a bandwidth of a cell-specific reference signal, CRS, based on the determining the presence of the at least one user equipment operating based on the configurable control channel monitoring, the controlling the bandwidth of the CRS comprising:
- determining a first subset of time resources and a second subset of time resources;
- and
- using a first CRS bandwidth value for the first subset of time resources and a second CRS bandwidth value for the second set of time resources, the second subset being different from the first subset and the second CRS bandwidth value being different from the first CRS bandwidth value.

A method for a measuring node, the method comprising:
- obtaining a bandwidth of a cell-specific reference signal CRS, for at least one resource associated with configurable control channel monitoring, the bandwidth of the CRS being controlled based on:
- a determined presence of at least one user equipment operating based on the configurable control channel monitoring;
- and
- a determined first subset of time resources and a second subset of time resources in which a first CRS bandwidth value is used for the first subset of time resources and a second CRS bandwidth value is used for the second set of time resources, the second subset being different from the first subset and the second CRS bandwidth value being different from the first CRS bandwidth value;
- and
- performing at least one operational task based on the obtained bandwidth.
