    摘要： 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.

    摘要： A novel key management approach is provided for securing communication handoffs between and access terminal and two access points. This approach provides for securely handing off communications between an access terminal and access point without risking exposure a master key for the access terminal. Temporary master keys are derived for low latency handoffs and secure authentication between a new access point and the access terminal. In one aspect, a distributive key management scheme is provided in which a current access point generates a new security key (based on its own security key) that is used by the next access point with which an access terminal communicates. In another aspect, a centralized key management scheme is provided in which a central authenticator maintains, generates, and distributes new security keys (based on a master security key associated with the access terminal) to access points.

    摘要： Systems and methodologies are described that facilitate providing hybrid cell access points that can support closed subscriber groups (CSG) while providing at least a minimum level of service to wireless devices excluded from the CSG. Hybrid cell access points can allow non-member wireless devices to camp and receive paging signals. Upon receiving a request for resources from non-member wireless devices, hybrid cell access points can handover the non-member wireless devices to an access point that can serve the non-member wireless devices, provide a portion of resources compared to a disparate portion provided to member wireless devices, and/or the like. In addition, hybrid cell access points can vary levels of service and downlink transmission power to provide load balancing for access points. Varying levels of service and downlink transmission power can facilitate additional functionality, such as reducing transmission power to serve member devices while mitigating interference to non-member devices.

    摘要： Systems and methodologies are described that facilitate providing user plane support for internet protocol (IP) relays. Service data units (SDU) received at a radio communication layer can be provided to an upper communication layer, such as a packet data convergence protocol (PDCP) layer, without regard to sequence numbers. The upper communication layer can handle reordering of the received protocol data units. Since communications related to a plurality of devices through one or more IP relays can be mapped over a single bearer, allowing reordering at the upper communication layer can mitigate delay caused where a donor or other upstream access point is delayed in providing a sequential SDU related to one of a plurality of devices downstream. In this regard, SDUs related to other devices can be processed by the upper communication layer while waiting for the sequential SDU.

    摘要： Systems and methods are provided that facilitate active queue management of internet-protocol data packets generated in a data packet switched wireless network. Queue management can be effected in a serving base station as well as in an access terminal, and the application that generates the data packets can be executed locally or remotely to either the base station or access terminal. Management of the generated data packets is effected via a marking/dropping of data packets according to an adaptive response function that can be deterministic or stochastic, and can depend of multiple communication generalized indicators, which include packet queue size, queue delay, channel conditions, frequency reuse, operation bandwidth, and bandwidth-delay product. Historical data related to the communication generalized indicators can be employed to determine response functions via thresholds and rates for marking/dropping data packets.
