    • 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.
    • 本公开提供了一种在无线中继场景中的频率重用的方法,其中根据小区中的场景参数将中心频谱,边缘频谱和随机接入频谱预先分配给小区; 计算小区中每个中继站(RS)覆盖的所有移动台(MS)的负载情况并将其报告给基站(BS); BS根据所有RS和时间表MS的负载条件向RS分配随机接入频谱。 本公开还提供了一种用于无线中继场景中的频率重用的系统。 通过上述方法和系统,可以配置频谱规划,引入随机接入频谱,同时考虑负载均衡和用户公平性,提高小区边缘吞吐量,特别是可以增加 吞吐量排名不佳的用户的吞吐量。
