Abstract: An enhanced paging mechanism is provided for UEs waking up from a very long paging cycle to improve paging robustness and flexibility. Enhanced paging includes absolute time paging (ATP) and paging with extended wakeup time. For absolute time paging, a UE receives ATP configuration and uses the actual wall time to calculate paging occasion if a condition is satisfied. In one embodiment, the wall time is acquired from at least one of an internal UE clock, a GPS time, information broadcasted from the network, or information from a higher layer signaling. For paging with extended wakeup time, a UE applies a long paging cycle followed by multiple normal paging cycles after waking up from the long paging cycle. In one embodiment, the long paging cycle is infinite and the UE enters normal paging cycle only upon TAU-triggered paging or uplink traffic.

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) indication of traffic-related information to network is provided. The method comprises a UE determining a traffic indicator and transmitting the traffic indicator to a base station. In one embodiment, the traffic indicator indicates either that default power consumption is preferred or low power consumption is preferred. For example, when the UE is in background traffic or sparse traffic, low power consumption is preferred. In another embodiment, the traffic indicator indicates a time pattern of the traffic history. From the network perspective, upon receiving and evaluating information contained in the traffic indicator, the network triggers a QoS modification procedure by applying one or more QoS modification algorithms.

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 method of failure event reporting for initial connection setup failure is proposed. In one embodiment, a UE first camps in RRC_IDLE mode in a cell served by a base station. The UE then detects a connection setup failure when performing a random access channel (RACH) procedure with the base station in an RRC connection attempt. The UE records a failure event report when the RACH procedure fails. Later, the UE transmits the failure event report to the network in RRC_CONNECTED mode. The failure event report comprises information that refers to the earlier RRC connection attempt. The failure event report also comprises available location information or available mobility measurements at the time the initial connection setup failure occurs. Based on the failure event report, the network can adopt corrective actions accordingly to mitigate the failure.

Abstract translation: 提出了一种初始连接建立失败的故障事件报告方法。 在一个实施例中，UE首先在由基站服务的小区中以RRC_IDLE模式驻留。 然后，在RRC连接尝试中，当与基站执行随机接入信道（RACH）过程时，UE检测连接建立失败。 当RACH过程失败时，UE记录故障事件报告。 稍后，UE以RRC_CONNECTED模式将故障事件报告发送到网络。 故障事件报告包括参考较早的RRC连接尝试的信息。 故障事件报告还包括在初始连接建立故障发生时可用的位置信息或可用的移动性测量。 根据故障事件报告，网络可采取相应的纠正措施，减轻故障。

Abstract: A method for scheduling request triggering based on traffic condition is provided. The method supports detecting a traffic condition, determining a modified scheduling request (SR) trigger based on the traffic condition and transmitting a scheduling request to a base station based on the modified SR trigger. In one embodiment, the modified SR trigger is a data buffer or a data generation rate exceeding a threshold. In one embodiment, the threshold is related to a prioritized Bit Rate (PBR) or a bucket Size Duration (BSD) or both. In another embodiment, the threshold is configured by the base station based on a size of the smallest grant under the traffic condition. In one embodiment, the threshold is updated when DRX state changes. In another embodiment, during DRX sleep state, the SR period is longer or SR is stopped.

Abstract: An enhanced connection recovery upon lost RRC connection due to radio link failure (RLF) or handover failure (HOF) is proposed. A UE first establishes an RRC connection in a source cell in a mobile communication network. Later on, the UE detects a failure event and starts an RRC reestablishment procedure in a target cell to restore the RRC connection. In a first novel aspect, a fast RLF process is applied to reduce the outage time in the serving cell. In a second novel aspect, an enhanced cell selection mechanism based on cell prioritization information is applied to reduce the outage time in the target cell. In one embodiment, multi-RAT registration is used to steer cell selection.

Abstract: A method of using additional uplink measurements for MDT UL coverage is provided. A base station (eNodeB) establishes a radio resource control (RRC) connection with a user equipment (UE) in a mobile communication network. The eNodeB and the UE are configured for Minimization of Drive Test (MDT). The eNodeB receives a Power Headroom Report (PRH) corresponds to a Physical Uplink Shared Channel (PUSCH) from the UE, and forwards the PHR to an MDT server. The eNodeB performs uplink measurement of a Demodulation Reference Signal (DM-RS) allocated in the PUSCH. The uplink measurement also involves measuring an uplink Received Interference Power (RIP) associated with the PUSCH. The eNodeB then reports uplink measurement results to the MDT server. The MDT server is able to determine uplink coverage based on the PHR and the uplink measurement results.
