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: Multiple data bearers may be configured for a user equipment (UE) for carrier aggregation and may be split among multiple evolved nodeBs (eNBs). The eNBs may be selected to serve the multiple data bearers for the UE based on various criteria such as channel conditions, loading, and the like. Various eNBs may be selected to serve data bearers for UE on a per data bearer basis, so that a particular eNB may be selected to serve each data bearer of the UE. Each data packet for the UE may then be sent via an appropriate data bearer.

Abstract: Techniques for femtocell message delivery and network planning are described herein. A mobile device sends a registration request to an access point, such as a femtocell access point. If denied registration, the mobile device may return to service by a macro cell access point. A network entity, such as a femtocell gateway serving the access point, may determine an identification of the mobile device. The network entity may send the identification of mobile device and an identifier of the access point to an application server. The application server may create and send a targeted message to the mobile device based on the identification of mobile device and the identifier of the access point. The application server may determine a user count for the access point and facilitate network planning based on the user count.

The method further includes determining whether the received configuration parameters comprise an indication for the access point to use white space (WS) for the service. The method further includes requesting authorization information from a WS database to operate in the WS, in response to the received parameters comprising the indication. An access point comprising a processor, memory and transceiver may be configured to perform the elements of the method, using a computer-readable storage medium or other means.

Abstract: The present disclosure presents a method and an apparatus for self-configuring a physical cell identify (PCI) at a cell upon detecting a PCI confusion at a neighbor cell. For example, the method may include detecting that a PCI confusion exists at a second cell based on a message (e.g., configuration update message or a X2 setup response message) received from the second cell. The first cell may initiate a timer that is selected from a first timer and a second timer, the first timer longer in duration than the second timer. The first cell then configures a new PCI for the first cell when the timer expires or maintains a current PCI for the first cell when the timer is reset prior to expiration. As such, self-configuration of PCI at a cell may be achieved.

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: Detecting local cell identifier collision by a base station may be achieved by receiving, at a first base station from a user device, a dedicated identifier associated with a second base station. The dedicated identifier may include or otherwise map to a user device identifier associated with the second base station and a local cell identifier associated with the second base station. Based on the dedicated identifier, it may be determined, at the first base station, that there is a local cell identifier collision between the first base station and the second base station.

Abstract: Handover parameter settings are automatically adapted in access points in a system to improve handover performance. Reactive detection techniques are employed for identifying different types of handover-related failures and adapting handover parameters based on this detection. Messaging schemes are also employed for providing handover-related information to access points. Proactive detection techniques also may be used for identifying conditions that may lead to handover-related failures and then adapting handover parameters in an attempt to prevent such handover-related failures. Ping-ponging may be mitigated by adapting handover parameters based on analysis of access terminal visited cell history acquired by access points in the system. In addition, configurable parameters (e.g., timer values) may be used to detect handover-related failures.
