    摘要： Systems and methodologies are described that facilitate distributing and utilizing interference information in a wireless communication environment. Interference information can be generated by a base station by evaluating uplink conditions, and disparate interference information can be collected from neighbor base station(s). Interference information associated with the base station and the neighbor base station(s) can be transmitted by the base station to access terminal(s). An access terminal that receives that interference information associated with the base station and the neighbor base station(s) can control an operation based at least in part upon the interference information. For example, the access terminal can adjust a transmit power, select a target serving base station for handover, and/or choose a random access channel (RACH) resource to use for random access as a function of the interference information associated with the base station and the neighbor base station(s).

    摘要： An inter-system handover system for a wireless communication system supports hand-down and hand-up of user equipment (UE) to different radio access technologies, including synchronous and asynchronous systems. Latency and handover connection failures are reduced by an access node (nodeB) broadcasting information about neighboring systems (targets) when the UE reception (RX) capability is both inside or outside the reception range of the target. A single RX chain is sufficient, although transitioning between a wireless wide area network (WWAN) to a wireless local area network may (WLAN) may advantageously benefit from simultaneous operation on two Rx chains. Optimized list of neighboring RAT systems (targets) are broadcast from the network, including measurement parameters and reporting instructions. Thereby, UE-driven reporting minimizes latencies. UE reports other-system searches to network only if needed for a handover. In addition, handover requests can be bundled with other-system measurement information, if necessary, for additional efficiencies.

    摘要： Channel dependent credit accumulation for determining a mobile handover is provided herein. In some aspects, a characteristic(s) of a source channel(s) serving a mobile device and of one or more target channels can be evaluated. Magnitudes of the evaluated characteristics can be utilized to generate handover credits associated with the target channel(s) (e.g., based on some function of a difference in the magnitudes). If a concurrent number of credits associated with a target channel equals or rises above one or more threshold levels, a mobile device can initiate a handover. As described, disparity in source and target channel quality, signal strength, etc., can be determined to increase probability of a handover based on channel degradation over one or more time intervals.

    摘要： System(s) and method(s) are provided for handover of a mobile terminal in a wireless communication system. Handoff resolution relies on both a downlink channel quality indication between a serving base station and the mobile terminal, and uplink channel quality indications amongst the terminal and a measurement set of target base stations. To generate UL channel quality indicators, the mobile station conveys a narrowband or broadband, sounding reference signal, and serving and target base stations measure UL and DL performance metrics (e.g., RSRP, RSSI, or RSOT). In backward handover, UL channel state information from target cells is received at the serving base station through backhaul communication, and handoff is resolved based on both UL and DL quality reports. In forward handover, the set of UL quality reports are conveyed to the mobile station to determine a target cell for handoff.

    摘要： Techniques to increase capacity in a wireless communications system. In an aspect, systematic non-transmission, or “blanking,” of minimal-rate frames transmitted in a communications system is provided. In an exemplary embodiment, eighth rate frames in a cdma2000 voice communications system are systematically substituted with null-rate frames carrying zero traffic bits. Provisions are nevertheless made for the transmission of certain designated as “critical” by, e.g., a vocoder. The receiver detects the presence of null rate or non-null rate transmissions and processes the received frames accordingly, including updating an outer loop power control only in response to non-null rate frames. Further techniques for changing the pilot transmission gating pattern to assist the receiver in detecting null rate frames are provided. In another aspect, early termination of a signal transmission over a wireless communications link is provided. In an exemplary embodiment, a base station (BS) transmits power control groups (PCG's) for a frame over a forward link (FL) to a mobile station (MS) until accurate reception of the frame is acknowledged by the MS over a reverse link (RL), possibly before all PCG's of the frame are received over the FL. Possible ACK signaling methods are defined for channels associated with a cdma2000 wireless communications system. In another exemplary embodiment, techniques for reverse link early termination are also provided.
