  • Patent number: 9578579
    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.

  • Publication number: 20170048733
    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.

  • Publication number: 20160295462
    Abstract: Handover failure modes are identified by logging information associated with at least one of a handover failure or a radio link failure. The information identifies whether or not a user equipment was engaged in an exchange of at least one of data traffic or control traffic with a network at the time that the handover failure or radio link failure occurred. The information is stored in a non-transitory computer-readable medium, and the information is reported to the network. The information is reported using a radio link failure or connection failure information signaling message. The severity of the handover failure or radio link failure is evaluated based upon the information.

  • Patent number: 9462564
    Abstract: An assignment of an uplink resource on which to send an uplink synchronization signal is transmitted to a user equipment. The user equipment sends on the uplink resource an uplink synchronization signal. From the uplink synchronization signal is determined a timing advance for the user equipment. Various indications are used to indicate to the user equipment that the assignment of uplink resources is for the purpose of sending its synchronization signal, such as expiration of its timing advance timer, a field in the allocation table that assigns the uplink resources, or explicit signaling from the network. Methods, devices, and computer program products are detailed for both network and user equipment embodiments.

  • Patent number: 9426708
    Abstract: Enhanced mobility for devices using a moving relay, or in a moving relay environment, may be valuable in the Long Term Evolution (LTE) of the 3rd Generation Partnership Project (3 GPP). In particular, enhanced mobility procedures for user equipment (UE) can be useful with respect to a moving relay and the radio access network (RAN) interface (IF) between the user equipment and the moving relay. Thus, certain embodiments can improve the mobility procedures between moving relays and macro layer (stationary nodes, for example, eNodeBs). A method according to certain embodiments can include determining, by a user equipment, a stable average of a signal characteristic of a signal from a mobile access point. The method can also include limiting handover of the user equipment based on the stable average.
