    • 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.
    • 用于无线通信系统的系统间切换系统支持用户设备(UE)向包括同步和异步系统的不同无线电接入技术的切换和交换。 当UE接收(RX)能力在目标的接收范围内部或外部时,接入节点(节点B)广播关于相邻系统(目标)的信息的延迟和切换连接故障被减少。 单个RX链是足够的,尽管在无线广域网(WWAN)到无线局域网(WLAN)之间的转换可以有利地受益于在两个Rx链上的同时操作。 相邻RAT系统(目标)的优化列表从网络广播,包括测量参数和报告指令。 因此,UE驱动的报告使延迟最小化。 只有在切换需要时,UE才会将其他系统搜索报告给网络。 此外,如果需要,可以将切换请求与其他系统的测量信息捆绑在一起以用于附加的效率。

    • Techniques for performing peer discovery in a wireless network are described. A device may perform peer discovery to detect and identify other devices of interest. In an aspect, the device may perform peer discovery based on a hybrid mode that includes autonomous peer discovery and network-assisted peer discovery. In another aspect, the device may perform peer discovery based on a push mode and a pull mode. For the push mode, the device may occasionally transmit and/or receive a peer detection signal. For the pull mode, the device may transmit and/or receive a peer discovery request when triggered. In yet another aspect, the device may perform event-triggered peer discovery (e.g., for the pull mode). In yet another aspect, the device may perform peer discovery using both a downlink spectrum and an uplink spectrum. In yet another aspect, the device may transmit a peer detection signal in a manner to improve detection and/or increase payload.
    • 描述了在无线网络中执行对等体发现的技术。 设备可以执行对等体发现以检测和识别感兴趣的其他设备。 在一方面,设备可以基于包括自主对等体发现和网络辅助对等体发现的混合模式来执行对等体发现。 在另一方面,设备可以基于推模式和拉模式来执行对等体发现。 对于推送模式,设备可能偶尔发送和/或接收对等体检测信号。 对于拉模式,当触发时,设备可以发送和/或接收对等体发现请求。 在另一方面,设备可以执行事件触发对等体发现(例如,用于拉模式)。 在另一方面,设备可以使用下行链路频谱和上行链路频谱来执行对等体发现。 在另一方面,设备可以以改进检测和/或增加有效载荷的方式发送对等检测信号。

    • Techniques for supporting MIMO transmission are described. Users are classified into a first group of users to be scheduled individually for MIMO transmission and a second group of users that can be scheduled together for MIMO transmission. Transmission resources are allocated to the first and second groups, e.g., based upon various criteria such as the number of users in each group, data requirements of the users, total loading for each group, etc. The transmission resources may be hybrid automatic retransmission (HARQ) interlaces, frequency channels, time frequency resources, etc. The resource allocation may be semi-static. The transmission resources allocated to each group are used for data transmission on the downlink and/or uplink for the users in the group. HARQ with blanking may be used for data transmission for the users in the first group. HARQ without blanking may be used for data transmission for the users in the second group.
    • 描述了支持MIMO传输的技术。 用户被分类为要单独调度用于MIMO传输的第一组用户和可以一起调度用于MIMO传输的第二组用户。 传输资源分配给第一组和第二组,例如基于各组用户数,各用户的数据需求,每个组的总负载等各种标准。传输资源可以是混合自动重传( HARQ)交织,频率信道,时间频率资源等。资源分配可以是半静态的。 分配给每个组的传输资源用于组中用户的下行链路和/或上行链路上的数据传输。 具有消隐的HARQ可以用于第一组中的用户的数据传输。 不消消息的HARQ可以用于第二组中的用户的数据传输。
