摘要： Discovery and synchronization channels are discussed for user-tracking zones in a cellular network. User-tracking zones reduce the mobility tracking burden on the UE and shift the tracking responsibility to the network. This shift allows for UE and network power savings from reduced searching at the UE as well as through efficient paging area tracking and less broadcast signaling. The various aspects provide channel design for initial synchronization and discovery of the user-tracking zones. A single frequency network (SFN) synchronization channel is provided with at least a reference signal for time synchronization and payload information that may include a zone identifier (ID), formatting for a system information transmission request, and resource allocation for the request. The zone ID may be included in the payload or embedded into the reference signal. Facility is also provided for handling zone nodes of different power classes that allows for maintaining the SFN operations.

摘要翻译： 讨论了蜂窝网络中用户跟踪区域的发现和同步信道。 用户跟踪区域减少了UE的移动性跟踪负担，并将跟踪责任转移到网络。 这种转移允许通过在UE处的减少的搜索以及通过有效的寻呼区域跟踪和更少的广播信令来UE减少网络功率。 各个方面提供用于初始同步和发现用户跟踪区域的信道设计。 提供单频网络（SFN）同步信道至少包括用于时间同步的参考信号和可以包括区域标识符（ID），用于系统信息传输请求的格式化和用于请求的资源分配的有效载荷信息。 区域ID可以包括在有效载荷中或嵌入到参考信号中。 还提供了用于处理不同功率等级的区域节点的设施，以允许维护SFN操作。

摘要： Methods and apparatus for communication comprise aspects that include performing a power management procedure for configuring a subset of network entities to receive one or more of downlink signal measurements and/or one or more uplink signal measurements. The methods and apparatus further comprise aspects that include storing the one or more one or more of downlink signal measurements and/or one or more uplink signal measurements associated with the subset of network entities at a database for managing transmit power at the subset of network entities. Moreover, the methods and apparatus comprise aspects that include adjusting a transmit power value of at least one of the subset of network entities from a first transmit power value to a second transmit power value based at least in part on the one or more of downlink signal measurements and/or one or more uplink signal measurements.
