ADAPTIVE POWER EFFICIENT RADIO ENVIRONMENT MEASUREMENTS
First Claim
1. A method of operating user equipment (UE) in a cellular telecommunications system, the method comprising:
- causing the UE to begin operating in a power saving state by determining that a first set of predefined criteria have been satisfied; and
causing the UE to leave the power saving state by determining that a second set of predefined criteria have been satisfied, wherein determining that the second set of predefined criteria have been satisfied includes;
making a plurality of signal quality measurements of a signal received from a serving cell during power saving state;
determining which of the plurality of signal quality measurements represents a best one of the signal quality measurements;
determining a threshold value as a function of the best one of the signal quality measurements; and
determining that the second set of predefined criteria have been satisfied if a current signal quality measurement satisfies a predefined relationship with respect to the threshold value.

Abstract
User equipment (UE) in a cellular telecommunications system is operated such that the UE is caused to begin operating in a power saving state by determining that a first set of predefined criteria have been satisfied and is caused to leave the power saving state by determining that a second set of predefined criteria have been satisfied. Determining that the second set of predefined criteria have been satisfied includes making a plurality of signal quality measurements of a signal received from a serving cell during power saving state; determining which of the plurality of signal quality measurements represents a best one of the signal quality measurements; determining a threshold value as a function of the best one of the signal quality measurements; and determining that the second set of predefined criteria have been satisfied if a current signal quality measurement satisfies a predefined relationship with respect to the threshold value.
