Abstract
Measurement handling is of interest in a user equipment (UE) in connected mode, with the UE being configured with multiple downlink component carriers (CCs). The UE evaluates the signal quality of a specific CC of the configured CCs against a configurable threshold to determine the need for neighbor cell measurements. The UE performs neighbor cell measurements if the signal quality of the specific CC is below the configurable threshold. In this way, robust and efficient measurement handling is provided, even though the UE is configured with multiple component carriers.
Claims27
A method of measurement handling in a user equipment (UE) in connected mode, the UE being configured with multiple downlink component carriers (CCs), the method comprising:
- evaluating a signal quality of a specific CC of the configured CCs against a configurable threshold to determine a need for neighbor cell measurements;
- and
- performing neighbor cell measurements if the signal quality of the specific CC is below the configurable threshold.
A control unit for measurement handling in a user equipment (UE) in connected mode, the UE being configured with multiple downlink component carriers (CCs), the control unit comprising at least one processing circuit configured to evaluate a signal quality of a specific CC of the configured CCs against a configurable threshold to determine a need for neighbor cell measurements, and to request neighbor cell measurements if the signal quality of the specific CC is below the configurable threshold.
A user equipment (UE) configured for measurement handling in connected mode, the UE being configured with multiple downlink component carriers (CCs) and comprising:
- at least one processing circuit configured to evaluate a signal quality of a specific CC of the configured CCs against a configurable threshold to determine a need for neighbor cell measurements, and to request neighbor cell measurements to be performed if the signal quality of the specific CC is below a configurable threshold;
- and
- at least one measurement circuit configured to perform, if requested, the neighbor cell measurements.
A non-transitory computer-readable medium having stored therein a set of instructions for performing, when executed by a computer-based system, measurement handling in a user equipment (UE) in connected mode, the UE being configured with multiple downlink component carriers (CCs), wherein a signal quality of a specific CC of the configured CCs is evaluated against a configurable threshold to determine a need for neighbor cell measurements, and neighbor cell measurements are requested to be performed if the signal quality of the specific CC is below the configurable threshold.
A method of measurement handling in a user equipment (UE) in connected mode, the UE being configured with multiple downlink component carriers (CCs), wherein the UE is configured with multiple thresholds, where each threshold relates to at least one respective measurement object, and each threshold is used for evaluating, for the CC on the object, whether there is a need to perform neighbor cell measurements on the object.
