Abstract: A method of throughput and data volume measurement for minimization of drive test (MDT) is proposed. A base station establishes a radio resource control (RRC) connection with a user equipment (UE) in a mobile communication network. The base station or UE measures transmitted or received data volume during a transmission time of a data burst between the base station and the UE. When the data burst spans multiple measurement periods and the data burst is split at each measurement period boundary. For each measurement period, data volume during the measurement period is measured to generate a measurement result. When throughput measurement is performed by the network, the base station receives location information that is available during the transmission time of the data burst. The data volume measurement is logged with time stamp such that each measurement result can correlated with the location information.

Abstract: A method of user equipment (UE) autonomous release RRC connection to reduce power consumption and signaling overhead is proposed. UEs sending small amount of data with long period, e.g., Machine-Type Communication (MTC) and Narrow-Band Internet of Things (NB-IoT) UEs, are allowed to be released autonomously after sending a given amount of data with corresponding request and configuration procedures. In one embodiment, UE sends an RRC connection request with UE autonomous release request, and receives an RRC setup message with UE autonomous release information. UE then transmits an RRC setup complete message with piggybacked uplink data. UE autonomously releases to Idle state upon expiry of an inactivity timer.

Abstract: Novel UE operation modes are proposed to improve the power consumption for potentially less mobile UEs, both for stationary UEs, almost stationary UEs, and limited mobility UEs by optimizing neighbor cell measurements and/or by optimizing UE wakeup sequence. Optimized neighbor cell measurements mean that the procedure can be done less frequently or not at all during certain conditions. Optimized wakeup sequence (with less wakeup time) mainly affect paging performance via UE implementations. It is an object of the current invention to allow UE to be aware of its mobility states, via either explicit configuration or self-estimation, and adjust its wakeup and measurement behaviors accordingly. Also, some UEs are allowed to switch among different mobility states, while other UEs are fixed in a given mobility state.

Abstract: Methods for UE enhancements for diverse data application are disclosed. In one embodiment of the invention, the UE applies a discontinuous reception (DRX) or discontinuous transmission (DTX) operation in a wireless network. The UE detects one or more predefined traffic conditions. Based on the detected traffic conditions, the UE either stays in the long DRX state longer or extends the short DRX cycle timer. In other embodiments of the invention, the UE configures an idle mode trigger condition. The UE detects one or more predefined traffic condition. Based on the detected traffic conditions, the UE may restart the inactivity timer. In other embodiments of the invention, the UE detects one or more predefined traffic conditions. The UE adaptively adjusts RLF triggering parameters based on the detected traffic conditions.

Abstract: Aspects of the disclosure provide a method for reflective quality of service (QoS) control and management at a user equipment (UE). The method can include creating a derived QoS rule belonging to a session and having a QoS flow identifier (QFI). The derived QoS rule includes a precedence value that is set to one of a precedence value associated with a session identifier (ID) of the session received from a core network (CN) of a wireless communication system during a session establishment procedure for establishing the session, a precedence value associated with the QFI received from the CN during the session establishment procedure for establishing the session or when a downlink QoS flow having the QFI is added to the session, or a precedence value that is defined by an operator of the wireless communication system.

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 generic access control procedure is proposed. Every action that is subject to access control is associated with an access category, and each access category is in turn associated with a set of access control parameters. From the APP layer, a UE detects an action that is subject to access control. The UE obtains and stores access categorization rules. In NAS layer, the UE determines the access category for the action. The UE then determines the set of access control parameters for the action. In AS layer, the UE finally applies the set of access control parameters to the action and makes a barring decision for the action. By defining a generic access control procedure and separating access control functions into NAS layer and AS layer, the generic access control is simplified and extendible.

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.
