    • An apparatus and method for monitoring (310) at least one factor relating to a wireless communication system (100) is provided such that a synchronization signal is sent (320) to at least one base transceiver station (130) neighboring a primary base transceiver station (120) at least in part according to a predetermined function of the monitored factor(s). The monitored factor may be any of several factors that weigh on the operation of the wireless communication system. The synchronization signal itself may vary in how it signals to the neighboring base transceiver station(s) (130) to synchronize with the data to be sent to a given mobile station (110) from its primary base transceiver station (120), and the number of synchronization signals sent over a given time may vary according to the predetermined function of the monitored factor(s).

    • A method (600) and apparatus (700) for reducing delay associated with a call set-up for a call between an originating communication unit (120) and a target communication unit (121-124) in a radio access system (RAS) (101) is described. A call is initiated with a target communication unit prior to a channel assignment. A first latency (411) between an initiation time and a time when the target is capable of receiving a notification of the call on a first channel (410) is estimated and a second latency (421) between the initiation time and a second time when the target is capable of receiving the notification on a second channel (420) is estimated. Addresses associated with the target can be sent to the radio access system on the first channel or the second channel based on the estimated first latency and the estimated second latency.

    • Various embodiments are described which may serve to improve spreading channel code selection in wireless technologies that employ two-stage ranging. For example, some of the embodiments enable a number of spreading codes to be reused at each network node (111, 112), potentially increasing the number of codes available to each remote unit and thereby reducing the collision rate. Rather than simply selecting a spreading channel code randomly, remote units (101-103), in some embodiments, select a spreading channel code based on one or more considerations such as pilot signal strength, remote unit location, a remote unit mobility level, and a priority class associated with the remote unit. Depending on the embodiment, network nodes can partition the spreading codes into groups and then assign link bandwidth to remote units based on the group associated with the code selected by that remote unit.
    • 描述了可以用于改进采用两级测距的无线技术中的扩展信道码选择的各种实施例。 例如,一些实施例使得能够在每个网络节点(111,112)处重新使用多个扩展码,从而潜在地增加每个远程单元可用的代码数量,从而降低冲突率。 在一些实施例中,远程单元(101-103)不是简单地随机选择扩展信道码,而是基于诸如导频信号强度,远程单元位置,远程单元移动性水平的一个或多个考虑来选择扩展信道码,以及 与远程单元相关联的优先级。 根据实施例,网络节点可以将扩展码划分成组,然后基于与由该远程单元选择的代码相关联的组,向远程单元分配链路带宽。
