## Abstract

Certain example embodiments provide systems, methods, apparatuses, and computer program products for handling of measurements relaxation and other activity skipping. The user equipment (UE) may be allowed to relax its various measurements if one or more radio link quality-based relaxation conditions are satisfied and based on whether the UE is also allowed, at the same time, to skip other activities. Based on certain embodiments, the UE may perform the measurements, if another activity has to be performed since relaxation may not provide any power saving benefit under such situation.

## Claims

### Claim 1

An apparatus, comprising:
at least one processor; and
at least one memory comprising computer program code,
the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus to:
determine whether at least one radio link quality-based condition for relaxation of a measurement is satisfied;
determine whether at least one user equipment activity-based additional condition is satisfied;
in response to determining that both the at least one radio link quality-based condition and the at least one user equipment activity-based additional condition are satisfied, determine that relaxation for the measurement is allowed to be performed;
receive a configuration of both of: the at least one radio link quality-based condition, and the at least one user equipment activity-based additional condition;
receive a signal;
determine whether relaxation for the measurement is allowed to be performed based on: the at least one radio link quality-based condition being satisfied, receiving a wake up signal that indicates to enter the relaxation of the measurement, receiving a dormancy indication that indicates to enter the relaxation of the measurement on a bandwidth part, and determining that a layer 1 reference signal received power measurement or reporting is allowed to be skipped;
determine whether relaxation for the measurement is not allowed to be performed based on: receiving a wake up signal that indicates to stop the relaxation of the measurement, and receiving a dormancy indication that indicates to stop the relaxation of the measurement on a bandwidth part;
based on a determination that the relaxation for the measurement is allowed to be performed, perform a relaxed measurement of the signal;
determine, prior to activating the relaxation for the measurement, whether at least one user equipment activity other than the measurement is scheduled to be performed during a period allocated for the relaxed measurement;
delay or skip the relaxation for the measurement when the at least one user equipment activity other than the measurement is not allowed to be skipped during that period;
determine an upper bound for a relaxation level of the measurement, wherein the upper bound is determined based on a periodicity of a layer 1 measurement and a periodicity of a layer 1 measurement reporting; and
receive a configuration indicating whether the radio link quality-based condition both the radio link quality-based condition and the at least one user equipment activity-based additional condition is to be evaluated to determine the relaxation of the measurement,
wherein the at least one user equipment activity-based additional condition comprises that at least one user equipment activity and the measurement is allowed to be skipped or relaxed,
wherein the determining of whether the at least one user equipment activity-based additional condition is satisfied is based on: whether a wake up signal ordering the apparatus to monitor a downlink control signal during a discontinuous reception on duration is received, whether a wake up signal indicating the apparatus to skip monitoring of a downlink control signal during a discontinuous reception on duration is received, whether a wake up signal indicating the apparatus to activate the relaxation of the measurement is received, whether a wake up signal ordering the user equipment to stop relaxing or skipping the measurement is received, whether a dormancy indication indicating that a bandwidth part has become non-dormant is received, whether a dormancy indication indicating that a bandwidth part has become dormant is received, whether a dormancy indication indicating the apparatus to activate the relaxation of the measurement is received, whether a dormancy indication ordering the apparatus to stop relaxing or skipping the measurement on the associated bandwidth part is received, and whether a layer 1 reference signal received power measurement or report is allowed to be skipped, and
wherein the at least one radio link quality-based condition is related low mobility of the user equipment, a location of the user equipment, a detection error rate of the user equipment, and power of a signal received by the user equipment.
