    • Systems and methodologies are described that facilitate enhancing acquisition and handoff in a wireless network deployment by leveraging primary pilots and secondary pilots. The deployment can support more than one frequency band for operation, yet a mobile device can receive signals on one frequency band at a given time. Thus, a base station can transmit primary pilot(s) over frequency band(s) associated with operating data channel(s) as well as secondary pilot(s) over frequency band(s) that lack data channel(s) for the base station. Moreover, the base station can convey information that indicates to a mobile device whether each pilot is primary or secondary. Further, the mobile device can employ knowledge of pilot type (e.g., primary or secondary) as well as signal strength to effectuate handoff decisions; thus, disruptions in communication can be mitigated.
    • 描述了通过利用主要飞行员和辅助飞行员来促进无线网络部署中的采集和切换的系统和方法。 该部署可以支持多个频带进行操作,但移动设备可以在给定时间在一个频带上接收信号。 因此,基站可以在与操作数据信道相关联的频带上发送主导频,以及在缺少用于基站的数据信道的频带上的辅助导频 站。 此外,基站可以向移动设备传送指示每个飞行员是主要还是次要的信息。 此外,移动设备可以使用导频类型(例如,初级或次级)的知识以及信号强度来实现切换决定; 从而可以缓解通信中断。
