    Abstract: Methods for enhanced heterogeneous network mobility are proposed. In a first novel aspect, the cell size of a target cell is considered when determining the TTT value. In one embodiment, pico-specific Time-to-Trigger (TTT) value is configured. When the target cell to be measured is a picocell, pico-specific TTT value is applied. In a second novel aspect, precise mobility state estimation (MSE) is achieved by considering the effect of cell size. In one embodiment, when counting cell changes, a cell change to/from a small cell would be counted to lesser extent than a cell change between large cells. UE uses effective parameters for measurement evaluation, by applying better speed state estimation with speed scaling and by applying parameter differentiation that can be dependent on cell size.

    Abstract: A wireless communication method and device are provided. The wireless communication method includes the steps of determining whether the length of an RLC SDU or RLC SDU segment is greater than a threshold; determining the type of length indicator which is allocated by a network when the length of the RLC SDU or RLC SDU segment is greater than the threshold; and determining whether to force to map the RLC SDU or RLC SDU segment to the end of an RLC PDU according to the type of the length indicator.

    Abstract: Apparatus and methods are provided for finer control for WLAN association. In one novel aspect, an enhanced NCWIK capability negotiation, an UE assistance information exchange, and an enhanced steering command are performed. In one embodiment, the enhanced NCIWK capacity negotiation includes additional UE information for fine selection. In another embodiment, the UE assistance information is sent to the eNB in addition to the measurement report. The UE assistance information is configured by the eNB. In yet another embodiment, the enhanced traffic steering command includes information of a target AP and one or more target channels. In one embodiment, the enhanced traffic steering command further includes channel direction information. In another novel aspect, the UE selects different UL and DL channels based on the received enhanced traffic steering command. In one embodiment, the UL and DL channels for the UE are different channels from the same AP or from different RATs.

    Abstract: Aspects of the disclosure provide a method that includes receiving a measurement configuration message indicating a predetermined number. A measurement event is defined based on the predetermined number of signal beams from a serving base station and the predetermined number of signal beams from a neighboring base station. The method also includes identifying a first number of best signal beams from the serving base station and a second number of best signal beams from the neighboring base station, where the first number and the second number are equal to or less than the predetermined number. The method further includes determining whether the measurement event occurs based on the first number of best signal beams from the serving base station and the second number of best signal beams from the neighboring base station, and sending a measurement report when the measurement event occurs.

    Abstract: A method of system information (SI) acquisition with reduced signaling overhead is proposed. To reduce SI broadcast overhead, the quantity of periodic SI broadcast and the frequency of on-demand SI acquisition need to be reduced. To reduce the frequency of on-demand SI acquisition, rather than always re-acquire SI when serving cell changes, UE is enabled to reuse stored SI information elements across different cells. More specifically, a novel concept of SI ID is introduced to be associated with an area that applies the same SI configuration. UE can reuse stored SI information elements if the stored SI information elements are valid based on the SI ID and validity check.

    Abstract: A novel and efficient connected mode cell reselection procedure is proposed to improve the mobility performance for user equipments (UEs) configured with extended connected mode Discontinuous Reception (DRX) cycle in LTE systems. A UE-centric mobility mechanism with which a UE performs cell reselection in RRC connected mode is proposed. The UE is allowed to select a target cell without handover signaling in the source cell and when needed to initiate signaling with the target cell, for which signal quality is much better. In this way, handover failures due to failed signaling in the source cell can be avoided. More specifically, the proposed mobility mechanism reduces signaling overhead and is inherently robust towards different DRX cycle settings, i.e., longer DRX cycles do not cause more failures, or more overhead, or more battery consumption.
