    • Techniques for determining whether a mobile device crosses a boundary defined by a first wireless access point (WAP) and a second fixed-location WAP are provided. A method according to these techniques includes receiving, at a mobile device, information defining a boundary defined by first and second fixed-location WAPs, the boundary being defined at least in part based on a ratio of a round trip time (RTT) between the mobile device and the first fixed-location WAP to a ratio of a RTT between the mobile device and the second fixed-location WAP, determining the ratio of the RTT between the mobile device and the first fixed-location WAP to a ratio of the RTT between the mobile device and the second fixed-location WAP, determining whether the mobile device has crossed the boundary, and triggering an event in response to the mobile device crossing the boundary.

    • Systems, apparatus and methods for determining a cyclic shift diversity (CSD) mode are presented. Examples communicate the CSD mode in a signaling message. Specifically, a CSD mode is set in an access point the sent to a mobile device. The signaling messages may be either a point-to-point message or a broadcast message. The access point or location server may set the current CSD mode from a plurality of mobile devices by crowd sourcing. For example, the plurality of mobile devices may report what CSD mode was detected. Alternative, the plurality of mobile devices may send a channel impulse response (CIR), or the like, to a location server and the location server may determine what CSD mode is currently used by the access point.
    • 提出了用于确定循环移位分集(CSD)模式的系统,装置和方法。 示例在信令消息中传送CSD模式。 具体地说,在发送到移动设备的接入点中设置CSD模式。 信令消息可以是点对点消息或广播消息。 接入点或定位服务器可以通过群众来源从多个移动设备设置当前的CSD模式。 例如,多个移动设备可以报告检测到什么CSD模式。 可替换地,多个移动设备可以向位置服务器发送信道脉冲响应(CIR)等,并且位置服务器可以确定接入点当前使用什么CSD模式。

    • The invention relates to an aided Global Positioning System (GPS) subsystem within a wireless device. The wireless device includes a wireless processing section capable of receiving signals from a wireless network and a GPS subsystem having a radio frequency (RF) front-end capable of receiving a GPS satellite signal. The wireless processing section of the wireless device receives an external clock and determines the offset between the clock in the wireless processing section and that of the external clock. The GPS subsystem then receives the offset information from the wireless processing section, information related to the nominal frequency of the wireless processing section clock and the wireless processing section clock. Using this information and the GPS clock in the GPS subsystem, the GPS subsystem determines an acquiring signal, which is related to a frequency offset between the GPS clock and the network clock. The GPS subsystem then acquires GPS satellite signals in an acquiring unit though the use of the acquiring signal.
    • 本发明涉及无线设备内的辅助全球定位系统(GPS)子系统。 无线设备包括能够从无线网络接收信号的无线处理部分和具有能够接收GPS卫星信号的射频(RF)前端的GPS子系统。 无线装置的无线处理部接收外部时钟并确定无线处理部中的时钟与外部时钟的时钟之间的偏移。 然后,GPS子系统接收来自无线处理部分的偏移信息,与无线处理部分时钟的标称频率和无线处理部分时钟有关的信息。 在GPS子系统中使用该信息和GPS时钟,GPS子系统确定与GPS时钟和网络时钟之间的频率偏移相关的获取信号。 然后,GPS子系统通过使用采集信号在获取单元中获取GPS卫星信号。
