Abstract: Methods of MDT information logging and reporting are provided. In one embodiment, a method is provided to resolve shortcomings of prior art by correlating UL measurements with QoS information to enable UL performance analysis and accurate detection of coverage problems. In another embodiment, a method is provided to resolve the shortcomings of the prior art by making DL measurements and location information collecting or logging conditional on UL measurements.

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 power control method to mitigate in-device coexistence (IDC) interference is provided. A wireless communication device (UE) is equipped with a first LTE radio module and a second co-located WiFi/BT/GSNN radio module. Upon detecting coexistence or IDC interference, the UE applies power control method to mitigate the interference. In a first embodiment, the LTE radio module adjusts its power parameters locally without informing the serving eNB. In a second embodiment, the LTE radio module adjusts its power parameters and implicit informs the eNB through existing PHR reporting. In a third embodiment, the LTE radio module changes its power or power class and explicitly informs the eNB through UE capability or new RRC message or MAC CE. Power control can be used as a low cost and lightweight solution before applying other heavyweight solutions that either require more resource or control overhead, or have higher impact on throughput.
Abstract translation: 提供了减轻设备间共存（IDC）干扰的功率控制方法。 无线通信设备（UE）配备有第一LTE无线电模块和第二共同配置的WiFi / BT / GSNN无线电模块。 在检测到共存或IDC干扰时，UE采用功率控制方法来减轻干扰。 在第一实施例中，LTE无线电模块在本地调整其功率参数而不通知服务eNB。 在第二实施例中，LTE无线电模块调整其功率参数，并通过现有的PHR报告暗示通知eNB。 在第三实施例中，LTE无线电模块改变其功率或功率等级，并通过UE能力或新的RRC消息或MAC CE明确地通知eNB。 在应用其他重量级解决方案之前，功率控制可以用作低成本和轻量级的解决方案，需要更多资源或控制开销，或对吞吐量有较高的影响。
