Abstract: A UE controls in-device coexistence (IDC) indication message generation to mitigate potential throughput impact on UE to maintain UE performance as much as possible. Under the proposed method, FDM-based solution is always preferred by the UE. Based on the IDC indication message generated by the UE, a network applies an IDC interference mitigation solution that prioritizes FDM-based solution. Specifically, the UE first sends an IDC message requesting FDM-based solution. In case the serving eNB does not respond, the UE sends a new IDC message by alternating IDC option. Even if a TDM-based solution has been received, the UE may continue requesting FDM-based solution to gain UE performance.

Abstract translation: UE控制设备内共存（IDC）指示消息生成，以减轻对UE的潜在吞吐量影响，以尽可能地维持UE的性能。 在所提出的方法下，UE始终优先采用基于FDM的解决方案。 基于UE生成的IDC指示消息，网络应用基于FDM的解决方案优先级的IDC干扰减轻解决方案。 具体地，UE首先发送请求基于FDM的解决方案的IDC消息。 在服务eNB不响应的情况下，UE通过交替的IDC选项发送新的IDC消息。 即使已经接收到基于TDM的解决方案，UE也可以继续请求基于FDM的解决方案来获得UE的性能。

Abstract: A method of fast link adaptation for Bluetooth long-range wireless networks is provided. A novel rate indication (RI) field is incorporated in a data packet to enable auto detection of rate adaptation at the receiver side. The data packet comprises a preamble, a first packet portion including the RI field, and a second packet portion including the PDU. The first packet portion is encoded with a first rate while the second packet portion is encoded with a second rate indicated by the RI field. The transmitting device raise/lower the encoding rate when the link quality is good/poor. The receiving device can provide recommended rate or link quality feedback information via an LMP message to help the transmitting device making rate adaptation decision. The transmitter can unilaterally decide the data rate for the second packet portion without receiver recommendation.

Abstract: Methods for preventing coexistence interference between a Bluetooth Low Energy (BLE) radio and a collocated LTE radio are provided. In a first solution, the BLE radio adds padding bytes to BLE packets such that the total packet length falls in a specific range to prevent coexistence interference. In a second solution, the BLE radio limits the total BLE packet length to a predefined length to prevent coexistence interference. In a third solution, the data rate for transmitting the BLE packets is higher than a predefined rate to prevent coexistence interference. In a fourth solution, the BLE radio dynamically adjusts the time inter-frame-spacing (T_IFS) value to prevent coexistence interference with the collocated LTE radio.
