Abstract: Responsive to receiving a request for a measurement in a mobile, the mobile determines whether time instances associated with the measurement coincide with time instances of location estimate availability in the mobile. Responsive to determining that location estimates are not available for a substantial fraction of the time instances when the measurement is requested, the mobile changes the time instances for the measurement and/or the time instances of location estimate availability to increase the availability of location estimates for the measurements.

Abstract: A network node receiving a preference for a power optimized configuration for a user equipment (UE) can in response change the UE's minimization of drive test (MDT) configuration to conserve UE power. For example, this change can be from immediate reporting of MDT measurements to connected mode logging MDT measurements or no reporting of MDT measurements; or to a longer interval for reporting them, or to drop the reporting of available location information with MDT measurements. Other teachings have actions by the UE, autonomous of the network, to conserve power. A UE receiving a MDT configuration having an MDT measurement reporting or logging interval, and also one or both of a discontinuous reception or paging configuration having a DRX/paging interval can adapt the MDT configuration autonomously of the network to conserve its battery power.

Abstract: A method, apparatus and software related product (e.g., a computer readable memory) for efficient measurement reporting by UEs to provide, for example, lower UE power consumption, efficient use of network resources, small cell ottloading, etc., in wireless networks such as LTE/LTE-A systems that can be also applied in inter-system cases such as a mix of UTRAN and E-UTRAN as one non-limiting example is presented. The UE performs measurements and event evaluation as in conventional LTE/LTE-A systems, but for certain cells/carriers an event triggered measurement report, which conventionally would be transmitted when time-to-trigger (TTT) expires (see details e.g. in 3GPP TS 36.331), is not transmitted but regarded as buffered (e.g., in a memory or buffered memory of the UE) as a candidate measurement report, when a predefined criterion is not met. This predefined criterion is e.g. a need at the UE to request network resources for uplink transmission by the UE.

Abstract: Various communication systems may benefit from well-defined measurement requirements. For example, measurements for multi-broadcast single-frequency networks (MBSFNs) may benefit from definition of minimum measurement requirements related to, for example, reference signal received power (RSRP) and reference signal received quality (RSRQ). A method may include obtaining MBMS configuration parameters. The method may also include defining generic minimum MBSFN measurement performance requirements, based on the MBMS configuration parameters.
