Abstract: The present disclosure describes methods and apparatus for detecting handover failures at an AP when the AP does not have an X2 interface with at least one of its neighbors. For example, methods are provided for detecting handover failures at an AP based on at least on a UE context release command message received from a mobile management entity (MME) and/or determining that a radio resource control (RRC) connection reconfiguration (RCR) message is not delivered to the UE.

Abstract: A timer parameter used for transitioning between radio protocol states is adapted based on a change of a handover parameter. For example, as a direct result of a change in a handover parameter such as time-to-trigger, offset, or hysteresis, an inactivity timer that is used for switching an access terminal from a connected state to an idle state may be adapted. As another example, as a direct result of a change in a handover parameter, a radio link failure (RLF) timer that is used for switching an access terminal to an RLF state may be adapted.

Abstract: Aspects of the methods and apparatus relate to exploiting the spectrum of a high power base station cell to provide higher capacity in a wireless communication system. Generally, a small cell with multi-carrier support may detect an absence of high power base station cell coverage or absence of high power base station cell users and may harness the high power base station cell carrier spectrum to provide higher data download rates and/or serve more mobility users. Specifically, aspects of the methods and apparatus include transmitting a first signal on a first carrier from a first access point and determining a current ability of a second access point on a second carrier. Thereafter, aspects of the methods and apparatus include transmitting a second signal on the second carrier from the first access point according to the determined current ability of the second access point.

Abstract: Scanning for femto access points includes scanning out-of-band (OOB) channels to discover OOB signals associated with the femto access point. When a femto access point is first discovered, a first type of scan is performed of each of the OOB channels. The user equipment (UE) determines whether any received responses originate from femto OOB access points and, if so, updates a search database of the UE. During subsequent visits to the area of the femto OOB access points, when the UE detects entry to a fingerprint area of the femto OOB access point, a second type of scan is performed, in which each of the OOB channels with femto OOB access points identified in the search database are scanned. If responses are detected to this second type of scan, a proximity indication is transmitted using in-band signals to a serving macro access point.

Abstract: Access terminals are provisioned to conduct intra - frequency, inter- frequency, and inter-RAT measurements and report physical layer identifiers of detected cells (106,108,110,112). The provisioning may involve cycling through all or a portion of a defined superset of physical layer identifier (PLI) one subset at a time. In addition, the physical layer identifiers (PLI) may be prioritized to improve the search procedure. Measurement report messages (MRMS) (including physical layer identifiers of the detected cells) are received at an access point (106) as a result of the provisioning. A neighbor cell list (118) for the femtocell is maintained based on the received measurement report messages (MRMS) and, optionally, other information. This other information may related to, for example, one or more of: physical layer identifier information (PLI) received from access terminals (104) that register with the access point, physical layer identifier information received via network listen operations (128), information regarding co-located cells (130), or physical layer identifier information received (134) from a network entity (114).

Abstract: Methods and apparatuses are provided that facilitate providing access point measurements to restricted access points. Restricted access points can lessen restrictions to allow devices to register with the restricted access point for providing measurements thereto. Additionally or alternatively, access point measurements can be provided to a minimization of drive tests (MDT) server for providing to the restricted access points. Thus, restricted access points can obtain the access point measurements for performing enhanced interference management or other functionality based at least in part on the measurements.

Abstract: Systems and methodologies are described that facilitate managing access control to Closed Subscriber Groups (CSGs) in a wireless communication environment. A user equipment (UE) can store an operator CSG list, which can be read only and controlled by an operator. Further, the operator CSG list can lack synchronization to a CSG subscription for the UE retained in the network. Thus, upon selecting to access a CSG cell associated with a CSG with a corresponding CSG Identifier (ID) included in the operator CSG list of the UE, a reject message that indicates that the UE lacks authorization for the CSG can be received. Moreover, the CSG ID can be stored as a forbidden CSG ID of the UE in a set of forbidden CSG IDs in response to receipt of the reject message when the CSG ID is included in the operator CSG list.

Abstract: An access point sends an indication or message to a network entity to indicate whether the network entity is to perform access control for an access terminal. In some implementations the indication/message may comprise an explicit indication of whether or not that network entity is to perform the access control. In some implementations, the inclusion of information (e.g., a CSG identifier) in the message or the exclusion of information from the message indicates whether the network entity is to perform the access control.
