    • A method of simultaneously providing channel quality feedback information in all valid sub-channels is provided to facilitate and improve the performance of dynamic transmission bandwidth adjustment and fast link adaptation. A receiving device receives a sounding signal over a wide channel in a wireless system. The sounding signal is transmitted from a transmitting device over multiple sub-channels of the wide channel. The receiving device estimates channel quality information based on the sounding signal for each sub-channel. The channel quality information includes estimated average SNR and recommended MCS and other channel quality metrics. The receiving device transmits a feedback message to the transmitting device. The feedback message contains the estimated channel quality information for all valid sub-channels within the transmission bandwidth. The transmitting device performs dynamic transmission bandwidth selection and fast link adaptation based on the channel quality information for all valid sub-channels.
    • 提供了一种在所有有效子信道中同时提供信道质量反馈信息的方法,以促进和改进动态传输带宽调整和快速链路自适应的性能。 接收设备在无线系统中通过宽频道接收探测信号。 探测信号通过宽信道的多个子信道从发送设备发送。 接收装置基于每个子信道的探测信号来估计信道质量信息。 信道质量信息包括估计的平均SNR和推荐的MCS等信道质量度量。 接收装置向发送装置发送反馈消息。 反馈消息包含传输带宽内所有有效子信道的估计信道质量信息。 发送设备根据所有有效子信道的信道质量信息,执行动态传输带宽选择和快速链路自适应。

    • 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.
    • 一种具有中央控制实体的无线设备,其协调位于同一设备平台内的多个无线电收发器,以减轻共存干扰。 无线设备包括LTE收发器,WiFi收发器,BT收发器或GNSS接收器。 在一个实施例中,中央控制实体从收发器接收无线电信号信息并确定控制信息。 控制信息用于触发FDM解决方案,使得收发器在指定的频道中工作,以减轻共存干扰。 在另一个实施例中,中央控制实体从收发器接收业务和调度信息并确定控制信息。 控制信息用于触发TDM解决方案,使得收发器被调度用于在特定持续时间内发射或接收无线电信号以减轻共存干扰。 在另一个实施例中,功率控制解决方案用于减轻共存干扰。
