    • Techniques are described that can be used to perform one or more of the following actions in order to reduce signal interference between WLAN and BlueTooth radios that are proximate to one another. One action is to selectively reduce a filter bandwidth in a WLAN radio applied to a received WLAN radio signal to reduce BlueTooth signal interference. An additional or alternative action is to selectively indicate a WLAN radio channel bandwidth larger than a channel bandwidth used for the WLAN radio so that the BlueTooth radio avoids transmitting over the indicated channel bandwidth. An additional or alternative action is to selectively reduce BlueTooth transmitter power in response to antenna isolation between BT and WLAN radio being less than a first threshold in order to reduce the likelihood of WLAN radio front end saturation.
    • 描述了可以用于执行以下动作中的一个或多个的技术,以便减少WLAN和接近彼此的蓝牙无线电之间的信号干扰。 一个动作是选择性地降低应用于所接收的WLAN无线电信号的WLAN无线电中的滤波器带宽以减少蓝牙信号干扰。 附加或替代的动作是选择性地指示WLAN无线电信道带宽大于用于WLAN无线电的信道带宽,使得蓝牙无线电避免通过所指示的信道带宽进行发送。 附加或替代的动作是选择性地减少BlueTooth发射机功率以响应于BT和WLAN无线电之间的天线隔离小于第一阈值,以便降低WLAN无线电前端饱和的可能性。

    • The disclosure provides a method for frequency reuse in a wireless relay scenario, wherein a center frequency spectrum, an edge frequency spectrum and a random access frequency spectrum are pre-allocated to a cell according to a scenario parameter in the cell; load conditions of all mobile stations (MSs) covered by each relay station (RS) in the cell is calculated and reported to a base station (BS); the BS allocates the random access frequency spectrum to an RS according to load conditions of all RSs and schedules MSs. The disclosure also provides a system for frequency reuse in a wireless relay scenario. With the method and system above, the frequency spectrum planning is configurable, the random access frequency spectrum is introduced, and both the load balancing and user fairness are taken into consideration, which improves the throughput at the edge of the cell, especially can increase the throughput for the users whose throughput ranks poorly.

    • Techniques are disclosed that involve communicating in bursty noise environments. For instance, a source device may send a probing packet to a destination device. This probing packet is for determining whether the communications medium (e.g., one or more frequency channels) is currently exhibiting a busy or jammed (e.g., due to bursty noise) condition. More particularly, based on whether an acknowledgment of the probing packet is received, the source device determines whether the channel is jammed (or busy) or clear. For example, an unacknowledged probing packet indicates that the channel is jammed or busy, while an acknowledged probing packet indicates that the channel is clear. If the channel is determined to be clear, then the source device may transmit one or more data packets to the destination device. Such data packet transmissions may be in accordance with a non rate-adaptive technique.
    • 公开了涉及在突发噪声环境中进行通信的技术。 例如,源设备可以向目的地设备发送探测分组。 该探测分组用于确定通信介质(例如,一个或多个频率信道)当前是否正在呈现忙或卡住(例如,由于突发噪声)条件。 更具体地,基于是否接收到探测分组的确认,源设备确定信道是否被卡住(或忙)或清除。 例如,未确认的探测分组指示信道被卡住或占线,而确认的探测分组指示信道是清除的。 如果信道被确定为清除,则源设备可以向目的设备发送一个或多个数据分组。 这样的数据分组传输可以是根据非速率自适应技术。
