Efficient measurement reporting by a user equipment (UE)

摘要

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. Thus, a UE being in connected mode but not actively transmitting data, will not report measurements resulting in likely handovers.

1. A method, comprising:
performing, by a user equipment, one or more measurements; evaluating, by the user equipment, one or more event related to the one or more measurements; and buffering, by the user equipment, a triggered measurement report when the one or more event is fulfilled during a time-to-trigger period and the user equipment does not need to request one or more resources from a network for uplink transmission, wherein the buffering occurs after the time-to-trigger period expires, wherein the triggered measurement report relates to the one or more event, and wherein the triggered measurement report is buffered as a candidate measurement report.
