摘要： A wireless remote unit performs SPS acquisition interleaved with receiving paging information over a wireless slotted paging channel and receiving data packets over a wireless data communication system. The remote unit tunes to a pilot channel, synchronizes to an internal clock of the wireless remote unit with a pilot signal transmitted over the pilot channel; and starts a search for SPS satellites after completing synchronization with the internal clock.

摘要： A method for assigning tracking elements includes sorting a list of potential assignments according to a diversity criterion. In one example, a list of received signal instances is sorted first according to a measure of energy and then sorted again according to the diversity criterion. In a further embodiment, a demodulation element may be labeled available for assignment yet continue to output demodulated symbols in a locked state. Applications to a mobile station of a CDMA system for cellular telephony are discussed.

摘要： A wireless mobile telephone (400) is operated so as manage the performance of "off-frequency searches," that is, searches for base station pilot signals that differ in frequency from the pilot signals in the mobile station's active set. Whenever frequency searching is performed (such as responsive to emerging from a reduced-power sleep mode), the mobile station performs on-frequency pilot signal searching (902) upon a prescribed active set frequency. Only if a prescribed off-frequency searching condition (903-908) is satisfied, the mobile station additionally performs off-frequency pilot signal searching (912) upon one or more neighboring base stations' frequencies.

摘要： Techniques to efficiently attempt acquisition of a packet data system (e.g., an IS-856 system). If a terminal has acquired one or more channels in a voice/data system (e.g., an IS-2000 system), then it can attempt acquisition on channels in the packet data system that are co-located with the acquired channels in the voice/data system. Multiple acquisition modes may be used, and on-going acquisition attempts on the co-located channels may be performed using one acquisition mode at a time in order to reduce power consumption. Acquisition attempts may be performed in a "ping-pong" manner to improve the likelihood of acquisition. For a ping-pong search, an acquisition attempt is made on the most recently acquired channel prior to an acquisition attempt on each of the remaining channels. Received signal strength estimates may also be obtained for selected channels and may be used to determine whether or not to attempt acquisition on these channels.
摘要翻译：有效地尝试采集分组数据系统（例如，IS-856系统）的技术。如果终端已经在语音/数据系统（例如，IS-2000系统）中获取了一个或多个信道，则它可以尝试在分组数据系统中与语音/数据系统中所获取的信道共同位置的信道上的采集，数据系统可以使用多个采集模式，并且可以一次使用一个采集模式来执行同位置信道上的持续采集尝试，以便降低功耗。收购尝试可以以“乒乓”方式进行，以提高获取的可能性。对于乒乓搜索，在对每个剩余通道进行获取尝试之前，在最近获取的通道上进行采集尝试。也可以对所选择的信道获得接收的信号强度估计，并且可以用于确定是否尝试在这些信道上进行采集。

摘要： To access a first communication system, a terminal determines a transmission time for an access probe, an expected response time from the system, and a protected time interval based on the transmission time and/or expected response time. The terminal determines a starting time for sending the access probe such that the protected time interval does not overlap a tune-away interval in which the terminal is to monitor anther frequency/air-interface. This starting time may be set initially to the end of a prior access probe plus a pseudo-random wait duration and may be advanced forward or moved backward in time, if needed, by a time duration selected such that the protected time interval does not overlap the tune-away interval.

摘要： Systems and techniques are disclosed wherein a gated pilot signal can be acquired by searching for a first gated pilot signal, deriving timing information from the search for the first gated pilot signal, and searching for a second gated pilot signal using the timing information. This can be implemented in a variety of fashions including a receiver with a searcher configured to generate a bit sequence, a correlator configured to correlate a received signal with the bit sequence, and a processor configured to detect a first gated pilot signal as a function of the correlation, derive timing information from the first gated pilot signal, and detect a second gated pilot signal by using the timing information to control the bit sequence generated by the searcher.
