    Abstract: Various examples and schemes pertaining to differentiation of user equipment (UE) in narrowband IoT (NB-IoT) are described. A processor of a UE generates a signal containing UE-specific information that is specific to the UE. The processor transmits the signal to a network node of a wireless network. The processor then receives a response from the network node, the response comprising an access stratum (AS) configuration created by the network node based on the UE-specific information. The processor also applies the AS configuration which reduces power consumption of the UE.

    Abstract: Concepts and examples pertaining to efficient coding switching and modem resource utilization in wireless communication systems are described. A processor of a modem of a user equipment (UE), configured with at least a first-capacity decoder and at least a second-capacity decoder, receives a common virtual carrier (CVC), a dedicated virtual carrier (DVC), or both. The CVC contains common information shared by multiple UEs, control information for the UE, and/or data information related to first data destined for the UE. The DVC contains control information for the UE, the first data, or a combination thereof. The first-capacity decoder decodes data of a small size up to a low data rate. The second-capacity decoder decodes data of a large size up to a high data rate. The processor determines whether to decode the first data using the first-capacity decoder or the second-capacity decoder based on the data information in the CVC.

    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 of network-based positioning using sounding reference signal (SRS) is proposed. An eNodeB configures a number of parameters of a periodic SRS transmission for a user equipment (UE). The eNodeB then transmits SRS configuration data for SRS measurements performed by a location measurement unit (LMU). The SRS configuration data includes cell-specific SRS bandwidth configuration and UE-specific SRS bandwidth configuration. The SRS configuration data may further include a number of antenna ports for SRS transmission, SRS frequency hopping bandwidth configuration, information on whether SRS sequence-group hopping is enabled, and ΔSS when SRS sequence hopping is enabled. Upon receiving the SRS configuration data, the LMU is able to perform timing measurements over the received SRS signals from the UE. In one embodiment, the LMU detects SRS dropping to avoid performance degradation of the network-based positioning.

    Abstract: Methods for UE measurement enhancement in an adaptive TDD configuration network are proposed. In a first solution, the network provides an adaptive TDD indicator to the UE. In a second solution, the network provides an instantaneous TDD configuration to the UE. In a third solution, multiple TDD configurations are grouped as one TDD group, and the network adapts TDD configurations within the same TDD group. In a fourth solution, the network broadcasts a TDD reference configuration in SIB1, and adapts to another TDD configuration with DL super set constraint, i.e., the DL subframes of the other TDD configuration form a super set of the DL subframes of the broadcasted TDD reference configuration.

    Abstract: 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.
