    • Systems and methodologies are described that facilitate identifying and/or selecting femto cells in a wireless communication environment. A mobile device can scan an Auxiliary Pilot Channel to detect auxiliary pilot channel information (e.g., a particular Walsh Code, . . . ) sent from a base station. Moreover, the identified auxiliary pilot channel information can be evaluated to detect a characteristic of the base station. For instance, the identified auxiliary pilot channel information can be compared with stored auxiliary pilot channel information (e.g., Walsh Code(s) included in a whitelist, blacklist, . . . ). Moreover, a Synchronization Channel can be read based upon the detected characteristic. Further, a Common Pilot Channel, for example, can be analyzed to search for pseudo-noise (PN) offset(s) reserved for femto cell base stations, and the scan of the Auxiliary Pilot Channel can be initiated in response to detecting at least one reserved PN offset.
    • 描述了有助于在无线通信环境中识别和/或选择毫微微小区的系统和方法。 移动设备可以扫描辅助导频信道以检测从基站发送的辅助导频信道信息(例如,特定沃尔什码,...)。 此外,可以评估所识别的辅助导频信道信息,以检测基站的特性。 例如,所识别的辅助导频信道信息可以与存储的辅助导频信道信息(例如白名单,黑名单中包括的沃尔什码)进行比较。 此外,可以基于检测到的特性来读取同步信道。 此外,例如,可以分析公共导频信道以搜索为毫微微小区基站保留的伪噪声(PN)偏移,并且响应于至少检测到的辅助导频信道的扫描可以被启动 一个保留的PN偏移。
