    • The invention includes a method and apparatus for creating a base station neighbor list at a target base station in a wireless network including a plurality of base stations. A method includes obtaining information for creating the base station neighbor list, creating the base station neighbor list using the obtained information, and storing the base station neighbor list. The obtained information includes at least one of geographic locations of ones of the base stations, network status information associated with the wireless network, and pilot signal strength measurement feedback information. The base station neighbor list includes a subset of the base stations of the network. The base stations of the base station neighbor list may be prioritized using at least a portion of the obtained information. The base station neighbor list may be updated periodically, or in response to changes to the obtained information. The base station neighbor list is distributed from the base station to wireless user devices served by the base station for use by the wireless user devices in making handoff decisions.
    • 本发明包括一种用于在包括多个基站的无线网络中的目标基站处创建基站邻居列表的方法和装置。 一种方法,包括获取用于创建基站邻居列表的信息,使用所获得的信息创建基站邻居列表,以及存储基站邻居列表。 获得的信息包括基站中的一个的地理位置,与无线网络相关联的网络状态信息和导频信号强度测量反馈信息中的至少一个。 基站邻居列表包括网络的基站的子集。 可以使用获得的信息的至少一部分来优先考虑基站邻居列表的基站。 可以周期性地更新基站邻居列表,或者响应于对获得的信息的改变。 基站邻居列表从基站分配给由基站服务的无线用户设备,供无线用户设备进行切换决定。

    • The invention includes a method and apparatus for adjusting the transmit power of a base station. In one embodiment, the transmit power of a base station is adjusted using rate metrics. A method according to one embodiment includes adjusting a transmit power of a target base station based on a per-user rate metric associated with the target base station and at least one per-user rate metric associated with at least one other base station. The per-user rate metrics may be based on any base station metrics, such as average system throughput of the base station, aggregate cell capacity of the base station, and the like. The per-user rate metrics may be computed or estimated using feedback information from wireless user devices. In one embodiment, the transmit power of a base station is adjusted using other information, such as geographic distances between base station, signal strength measurements received at base stations from other base stations, and the like, as well as various combinations thereof. A method according to one embodiment includes obtaining non-feedback information and adjusting the transmit power of the base station using the non-feedback information.
    • 本发明包括一种用于调整基站的发射功率的方法和装置。 在一个实施例中,使用速率度量来调整基站的发射功率。 根据一个实施例的方法包括基于与目标基站相关联的每用户速率度量以及与至少一个其他基站相关联的至少一个每用户速率度量来调整目标基站的发射功率。 每用户速率度量可以基于任何基站度量,例如基站的平均系统吞吐量,基站的聚合小区容量等。 可以使用来自无线用户设备的反馈信息来计算或估计每用户速率度量。 在一个实施例中,使用诸如基站之间的地理距离,在其他基站的基站处接收到的信号强度测量等的其他信息以及其各种组合来调整基站的发射功率。 根据一个实施例的方法包括获得非反馈信息并使用非反馈信息来调整基站的发射功率。
