Abstract
The present disclosure relates to a user equipment (UE) comprises a receiver that receives a plurality of reference signals. Processing circuitry of the UE performs power-related measurements on the plurality of reference signals. The processing circuitry determines the availability of reference signals among the plurality of reference signals for the power-related measurements. The processing circuitry generates measurement results based on the performed power-related measurements and depending on the determined availability of the reference signals.
Claims14
A user equipment, UE, comprising:
- a receiver, which in operation, receives a plurality of reference signals;
- processing circuitry, which in operation, performs power-related measurements on the plurality of reference signals;
- the processing circuitry, when in operation, determines the availability of reference signals among the plurality of reference signals for the power-related measurements and determines the number of reference signals during a measurement time period that are not available while performing the power-related measurements;
- and
- the processing circuitry, when in operation, determines a measurement accuracy parameter reflecting the measurement accuracy of the power-related measurements, based on the determined number of non-available reference signals, and generates measurement results including the determined measurement accuracy parameter based on the performed power-related measurements and depending on the determined availability of the reference signals,
- wherein
- the non-available reference signals include missing reference signals that are not received at all by the UE and un-qualified reference signals that are received by the UE but have a power below a power threshold;
- and
- the measurement accuracy parameter is a ratio between the determined number of non-available reference signals during the measurement time period and the total number of reference signals expected during the measurement time period.

A base station, comprising:
- a transmitter, which in operation, transmits a plurality of reference signals in a radio cell controlled by the base station;
- a receiver, which in operation, receives measurement results from a user equipment, UE, based on power-related measurements performed by the user equipment on the reference signals, the measurement results including measurement values reflecting the power of the reference signals during a measurement time period, and the measurement results including a measurement accuracy parameter that is based on the number of reference signals during a measurement time period that are not available while the UE performs the power-related measurements and that reflects the measurement accuracy of the power-related measurements;
- and
- processing circuitry, which in operation, determines whether to handover the user equipment from the radio cell to another radio cell, based on the received measurement values and measurement accuracy parameter of the measurement results,
- wherein
- the non-available reference signals include missing reference signals that are not received at all by the UE and un-qualified reference signals that are received by the UE but have a power below a power threshold;
- and
- the measurement accuracy parameter is a ratio between the determined number of non-available reference signals during the measurement time period and the total number of reference signals expected during the measurement time period.
