    Abstract: A radio frequency receive chain of an access point is reused for different functions. For example, the same RF receive chain may be used to receive on a downlink at certain points in time and on an uplink at other points in time. An RF receive chain that is used to derive synchronization from downlink signals received from a macro system also may be used to receive uplink signals from an access terminal to provide assistance for hand-in of the access terminal. Accelerated searching for hand-in may be provided through the use of a relatively small search window for hand-in of an access terminal to a small coverage access point. In some aspects, the search window may be defined based on the distance between access points or calibration of synchronization error between access points.

    Abstract: Ambiguity (e.g., confusion) associated with access point identifiers may be resolved by querying candidate target access points and/or by using historical records indicative of one or more access points that the access point has previously accessed. For example, messages may be sent to access points that are assigned the same identifier to cause the access points to monitor for a signal from an access terminal that received the identifier from a target access point. The target access point may then be identified based on any responses that indicate that a signal was received from the access terminal In some aspects the access points subject to being queried may be selected using a tiered priority. In addition, it may be determined based on prior handoffs of a given access terminal that when that access terminal reports a given identifier, the access terminal usually ends up being handed-off to a particular access point. Accordingly, a mapping may be maintained for that access terminal that maps the identifier to that access point so that the mapping may be used to resolve any future confusion associated with the use of that identifier by that access terminal

    Abstract translation: 可以通过查询候选目标接入点和/或通过使用指示接入点先前访问的一个或多个接入点的历史记录来解决与接入点标识符相关联的模糊性（例如，混淆）。 例如，消息可以被发送到被分配了相同标识符的接入点，以使得接入点监视来自接收来自目标接入点的标识符的接入终端的信号。 然后可以基于指示从接入终端接收到信号的任何响应来识别目标接入点。在某些方面，可以使用分层优先级来选择被查询的接入点。 此外，可以基于给定接入终端的先前切换来确定当接入终端报告给定标识符时，接入终端通常最终被切换到特定接入点。 因此，可以为将该标识符映射到该接入点的该接入终端进行映射，使得该映射可用于解决与该接入终端的该标识符的使用相关联的任何将来的混淆
