Abstract: A mobile device may be configured to perform concurrent Satellite Positioning System (SPS) operation and wireless communications when uplink signals transmitted by the mobile device interferes with the reception of SPS signals in one or more frequency bands. The mobile device may determine if the SPS receiver has already acquired SPS signals and is in a tracking state. If the SPS receiver is not in a tracking state, an SPS acquisition procedure is initiated before the wireless communication session is initiated. The SPS acquisition procedure is performed until the SPS receiver reaches a tracking state, or until a timeout is reached. Once the SPS receiver is in a tracking state, the wireless communication session may be initiated, during which the SPS receiver is controlled, e.g., to perform signal blanking, measurement exclusion, or disable SPS reception, to mitigate interference with SPS signals.

Abstract: Satellite ephemeris data associated with satellite vehicles in a Global Positioning System (GPS) based position location system can be selectively transmitted to a mobile station within a wireless communication system. The mobile station can selectively request satellite ephemeris data from a Position Determination Entity (PDE) that is in communication with one or more GPS satellite vehicles (SV). The mobile station forecasts the satellite vehicles that theoretically are available. Then, the mobile station checks to see if valid ephemeris data is locally stored. If ephemeris data is desired and not locally available, the mobile station transmits a selective ephemeris request to the PDE and receives, in response to the request, the ephemeris corresponding to the SV identified in the ephemeris request. The selective ephemeris request and selective satellite update method can be implemented in accordance with presently available position location standards.

Abstract translation: 可以选择性地将无线通信系统中的移动台发送与基于全球定位系统（GPS）的位置定位系统中的卫星车辆相关的卫星星历数据。 移动台可以从与一个或多个GPS卫星车辆（SV）通信的位置确定实体（PDE）中选择性地请求卫星星历数据。 移动台预测理论上可用的卫星车辆。 然后，移动台检查是否有效的星历数据被本地存储。 如果星历数据是期望的而不是本地可用的，则移动台向PDE发送选择性星历请求，并响应于该请求接收与在星历表中确定的SV相对应的星历表。 选择性星历请求和选择性卫星更新方法可以根据目前可用的位置定位标准来实现。
