摘要： Systems and methodologies are described that facilitate evaluating and utilizing timing updates in a wireless communications network. A base station can transmit timing adjustment commands to mobile devices as needed as opposed to a periodic timing update where timing adjustment commands are always sent within a certain period. However, the mobile devices need to stay awake to monitor the timing adjustment message resulting in high power consumption. On the other hand, with periodic update, the mobile devices can wake up to check whether there is a timing adjustment for itself and, if not, return to a sleep mode. With the proposed method, a mobile device can sleep for a period of time to check for timing adjustment commands upon waking. Thus, both the mobile power consumption and downlink signaling overhead are reduced.

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： Systems, methodologies, and devices are described that can facilitate bandwidth efficient non-coherent signaling for uplink control channel transmissions. A communication device (e.g., a mobile device, base station) can be configured to utilize or generate a set of complex orthogonal codewords to facilitate transmission of control channel information using non-coherent signaling in a bandwidth efficient manner. A complex orthogonal codeword set can comprise a first subset of codewords where such codewords have a desirable cross-correlation property and another subset(s) of codewords that can include expurgated codewords, where the expurgated codewords can include discarded codewords and/or codeword pairs that produce a worst-case cross-correlation property. The codeword set and subsets are determined based at least in part on a predefined codeword criterion. A portion of the discarded codewords can be used for other purposes, such as erasure decoding, interference-level estimation, and/or multi-mode control channel operation.

摘要： Techniques for transmitting information using cyclically shifted sequences are described. In one design, first and second sequences may be generated by cyclically shifting a base sequence by first and second amounts, respectively. The base sequence may be a CAZAC sequence, a PN sequence, or some other sequence having good correlation properties. The cyclic shifts for the first and second sequences may be determined based on a hopping pattern. A first modulated sequence may be generated based on the first sequence and a first modulation symbol and may be sent in a first time interval. A second modulated sequence may be generated based on the second sequence and a second modulation symbol and may be sent in a second time interval. Each modulated sequence may be sent on K consecutive subcarriers using localized frequency division multiplexing (LFDM)

摘要： Systems and methodologies are described that facilitate multiplexing unicast reference symbols and multicast transmissions in the same transmission time interval. In particular, mechanisms are provided that enable multiplexing unicast reference symbols to single frequency network transmissions that utilize a longer cyclic prefix duration.

摘要： A system and method for inter-cell interference mitigation in FDM systems is provided. The system provides for increased efficiency with load metric data generated per subband for both serving and neighboring non-serving cells. The system robustly provides for sharing load metric date per subband through a backhaul channel as well as directly from cell to adjacent cell. Furthermore, a UE based communication system allows UE reduction of assigned load controls based on directly reading a neighboring cells' load metrics. The system thus robustly handles various cell types (e.g. synchronous or asynchronous) and a variety of UE capabilities while providing increased efficiency in managing inter-cell interference.
