Abstract: Methods, systems, and devices for enhanced neighbor discovery through enhanced automatic neighbor relations (ANR) and for detecting cell identifier confusion and are described. Neighboring base stations may provide information to one another, including using ANR, that may avoid or help to resolve cell identity confusion. For example, a NHN-ID may be defined to avoid or resolve cell identify confusion. A wireless device, such as a base station or a user equipment (UE), may determine whether neighboring cells are using a common cell identifier and may adjust operations accordingly. For example, a device may detect physical cell identity (PCI) confusion by determining whether two neighboring cells have the same PCI and different Evolved Universal Terrestrial Access Network (E-UTRAN) Cell Global Identifiers (ECGIs) or different Neutral Host Network Identifier (NHN-IDs). A network entity may then inform the neighboring cells having the same PCI of the confusion.

Abstract: Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.

Abstract: Techniques are provided for channel discovery. For example, there is provided a method operable by a mobile entity that may involve measuring beacon signals associated with the network. In one approach, the method may involve, in response to detecting an Authorized Shared Access (ASA) beacon signal on a frequency common to each network entity on a given ASA channel, extracting frequency information from the ASA beacon signal, wherein the ASA beacon signal comprises a single frequency network (SFN) beacon signal. In another approach, the method may involve, in response to detecting an ASA beacon signal on a frequency common to each network entity on a given ASA channel, extract frequency information from the ASA beacon signal, wherein timing correlates with an operating frequency for the ASA beacon signal.

Abstract: Techniques for prioritizing inter-frequency measurements are disclosed. The method may include identifying a first frequency for measurement that is associated with mobility of an access terminal for transitioning from a serving primary cell to a target primary cell, identifying a second frequency for measurement that is associated with supplemental capacity of the access terminal for adding a secondary cell to operate in conjunction with the serving primary cell, prioritizing the mobility of the access terminal or the supplemental capacity of the access terminal, selecting for measurement in a measurement period either the first frequency or the second frequency based on the prioritizing, and triggering a measurement for the selected frequency.

Abstract: Fractional frequency reuse (FFR) is defined based on a mobility condition of an access terminal. For example, upon determining that an access terminal is moving (or at a cell edge, or experiencing poor link conditions, etc., due to mobility), FFR may be defined for the serving access point of the access terminal and/or for neighbor access points to maintain acceptable link quality for the access terminal. In particular, FFR may be defined in a manner that frees-up or otherwise reserves resources for the access terminal. For example, the serving access point may allocate additional sub-bands for the access terminal and/or increase the power levels used on the sub-bands allocated for the access terminal. In addition, neighbor access points may back-off these sub-bands.

Abstract: Methods and apparatuses are described for providing a shared eNodeB that is configured to provide shared network access to UEs associated with disparate cellular service providers, or operators, over one or more unlicensed frequency bands in a multi-operator, heterogeneous, and dual-connectivity-compatible system. In an example methodology, a shared eNodeB may establish a secondary communication link with a first user equipment associated with a first operators primary cell, then may establish another secondary communication link with a second UE associated with a second operators primary cell, wherein the shared eNodeB is configured to communicate with both a first core network associated with the first operator and a second core network associated with the second operator, and may communicate wirelessly over one or more unlicensed frequency bands with both the first UE via the first communication link and the second UE via the second communication link.

Abstract: Systems and methodologies are described that facilitate transmitting access point types and/or restricted association parameters using broadcast signals, such as beacons, pilot signals, etc. The type or restricted association information can be indicated by one or more intrinsic aspects of the signal, such as specified parameters. In addition, the type or information can be indicated by one or more extrinsic signal aspects, such as frequency, interval, periodicity, etc. Using this information, a mobile device can determine whether an access point implements restricted association. If so, the mobile device can request an access point or related group identifier before determining whether to establish connection therewith. The identifier can be verified against a list of accessible access points and/or groups to make the determination.

Abstract: A method and an apparatus for a light active estimation mechanism for backhaul management at a small cell base station are disclosed. For example, the method may include transmitting a first data packet from the small cell base station to a network entity, receiving a second data packet from the network entity in response to the transmission, calculating a time delay between the transmitting of the first data packet and the receiving of the second data packet, and determining whether or not a backhaul of the small cell base station is congested based on the calculated time delay. As such, light active estimation mechanism for backhaul management at a small cell base station may be achieved.

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: A method for enhancing assignment of mobility classifications to mobile devices is described. A plurality of mobility classifications are stored in association with a plurality of mobile devices to indicate, for each mobile device, one or more handover parameters used by the mobile device. One or more handover parameters associated with the plurality of mobility classifications are updated based on mobility events. An error determination is made that one or more of the one or more mobile devices are incorrectly associated with the mobility classifications based on the one or more updated handover parameters for the plurality of mobility classifications. In response to the error determination, one or more new criteria are established that adjust how the mobility classifications are assigned.
