    Abstract: A method of implicit signaling to support In-Device coexistence interference avoidance is provided. A UE sends an IDC interference indication to an eNB. The indication indicates that a serving frequency becomes unusable due to a coexistence interference problem. The indication does not explicitly indicate a frequency index or a frequency location of the unusable serving frequency. The eNB determines the serving frequency as unusable in an implicit manner. The eNB also determines an implied unusable frequency region based on the received IDC indication. The implied unusable frequency region is between the serving frequency and the ISM band. In one advantageous aspect, the eNB configures a condition for the UE, such that the UE is refrained from sending IDC interference indications unless the condition is satisfied.

    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 reporting UE measurement state information in RLF report is provided. A UE performs radio measurements of a serving cell and neighbor cells in a mobile communication network. The UE evaluates a measurement reporting criteria and attempts to access the network to deliver a measurement report if the criteria is met. The UE then detects a radio link failure or a handover failure event and reconnects to the network by performing RRC reestablishment or RRC establishment. Finally, the UE transmits a failure event report to the network. The failure event report comprises UE measurement state information corresponds to the failure event. The UE measurement state information helps the network to determine whether to apply corrective actions to mitigate the failure.

    Abstract: Various methods for wireless communication in a device with co-existed/co-located radios are provided. Multiple communication radio transceivers are co-existed/co-located in a user equipment (UE) having in-device coexistence (IDC) capability, which may result in IDC interference. For example, the UE is equipped with both LTE radio and some ISM band applications such as WiFi and Bluetooth modules. In a first method, the network identifies IDC capability by UE identification (e.g., UE ID). In a second method, the UE intentionally performs cell selection or reselection to cells in non-ISM frequency bands. In a third method, the UE signals the existence of ISM band applications via capability negotiation. In a fourth method, the UE signals the activation of ISM band applications by signaling messages (e.g., RRC message or MAC CE). Under the various methods, the UE and its serving eNB can apply FDM or TDM solutions to mitigate the IDC interference.

    Abstract: A wireless device having a central control entity that coordinates multiple radio transceivers co-located within the same device platform to mitigate coexistence interference. The wireless device comprises an LTE transceiver, a WiFi transceiver, a BT transceiver, or a GNSS receiver. In one embodiment, the central control entity receives radio signal information from the transceivers and determines control information. The control information is used to trigger FDM solution such that the transceivers operate in designated frequency channels to mitigate co-existence interference. In another embodiment, the central control entity receives traffic and scheduling information from the transceivers and determines control information. The control information is used to trigger TDM solution such that the transceivers are scheduled for transmitting or receiving radio signals over specific time duration to mitigate co-existence interference. In yet another embodiment, power control solution is used to mitigate coexistence interference.
