摘要： 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.

摘要： 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.
摘要翻译：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。

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Various examples and schemes pertaining to simple Ethernet header compression are described. A first network node transmits a first packet with a full header to a second network node. The first network node determines whether a header compression context for the full header has been established by the second network node. In response to determining that the header compression context for the full header has been established by the second network node, the first network node transmits a second packet with a compressed header to the second network node. In response to determining that the header compression context for the full header has not been established by the second network node, the first network node transmits the second packet or a third packet with the full header to the second network node.

摘要： Various examples and schemes pertaining to NB-IoT physical random access channel (PRACH) resource partitioning and multiple grants in random access response (RAR) for early data transmission (EDT are described. A network node schedules multiple grants for EDT during a random access (RA) procedure with a user equipment (UE). The network node transmits to the UE a message indicating the multiple grants mapped to a maximum broadcast transport block size (TBS) configured for each of one or more preamble resource of a plurality of preamble resources. The UE calculates a TBS that fits an uplink (UL) data packet of the UE. The UE selects one or more PRACH resources for EDT for the TBS based on a wireless communication coverage of the UE by the network node. The UE transmits to the network node in the RA procedure a first message (Msg1) indicating the selected one or more PRACH resources.
