摘要： Providing for improved error control signaling in wireless communications is disclosed herein. By way of example, multiple transmissions can be conducted for a HARQ process prior to a scheduled feedback signal on the HARQ process, causing a receiving device to combine the multiple transmissions, rather than treat them as separate transmissions. In this manner, multiple transmissions can be employed to increase overall receive energy, without violating maximum transmit power constraints in a wireless communication. Further, these multiple transmissions can be configured based on prevailing signal strength at the receiving device, or based on processing capabilities of the receiving device, providing flexible protocols that can accommodate advanced as well as legacy UEs in wide range of wireless conditions.
摘要翻译：本文公开了在无线通信中提供改进的差错控制信令。作为示例，可以在HARQ过程之前的调度的反馈信号之前对HARQ进程进行多个传输，使得接收设备组合多个传输，而不是将其作为单独的传输。以这种方式，可以采用多个传输来增加总体接收能量，而不违反无线通信中的最大发射功率约束。此外，可以基于接收设备处的主要信号强度或基于接收设备的处理能力来配置这些多个传输，从而提供可在宽范围的无线条件下适应高级以及传统UE的灵活协议。

摘要： Techniques for transmitting and receiving data in an efficient manner to potentially improve capacity for a wireless network and achieve power savings for a wireless device are described. The techniques utilize a Continuous Packet Connectivity (CPC) mode comprised of multiple (e.g., two) discontinuous transmission (DTX) modes and at least one (e.g., one) discontinuous reception (DRX) mode. Each DTX mode is associated with different enabled uplink subframes usable for transmission from the wireless device to the network. Each DRX mode is associated with different enabled downlink subframes usable by the network for transmission to the wireless device. The wireless device may send signaling and/or data on the enabled uplink subframes and may receive signaling and/or data on the enabled downlink subframes. The wireless device may power down during non-enabled subframes to conserve battery power. Mechanisms to quickly transition between the DTX and DRX modes are described.

摘要： An apparatus, method, processor(s), and computer program product avoids user data loss by network-controlled, user equipment assisted handover in a wireless data packet communication system. A wireless receiver receives radio link control (RLC) packet data units (PDUs) from user equipment (UE) being served by a source node. A wireless transmitter commands the UE to handover. A network communication interface transmits RLC Uplink (UL) context from the source node to the target node, and transmits RLC Downlink (DL) initialization message and buffered in-transit DL RLC PDUs from the source node to the target node.

摘要： Techniques for sending data during handover with Layer (2) tunneling are described. In one design, a user equipment (UE) sends first Layer (2) packets to a source base station prior to handover to a target base station. The UE sends at least one second Layer (2) packet to the target base station, which identifies the second Layer (2) packet(s) as being intended for the source base station and thus forwards the second Layer (2) packet(s) to the source base station via a Layer (2) tunnel. The UE sends third Layer (2) packets to the target base station after the handover. The target base station processes the third Layer (2) packets to obtain IP packets and sends the IP packets to a serving gateway after a trigger condition, which may be defined to achieve in-order delivery of IP packets from the source and target base stations to the serving gateway.

摘要： Systems and methodologies are described that facilitate security activation within a specified security activation time. Thus, where handover occurs or is initiated within the activation time, security keys can be activated in such a way as to not be substantially affected by the handover. In one example, a handover time can be set to occur beyond the security activation time to ensure the security activation happens first. Additionally, a handover command can comprise security keys that can be activated upon handover in another example. Moreover, in non-real-time contexts, dummy packets can be transmitted to allow timer operability with packet sequence numbering, or security activation times can be substantially ignored by utilizing a verification process.

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.
摘要翻译：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，切换请求可以与其他系统测量信息捆绑在一起以用于附加效率。

摘要： Techniques for supporting broadcast, multicast, and unicast services in a cellular system are described. A Node B may multiplex data for broadcast and multicast services and data for unicast services on radio resources available for transmission. The Node B may periodically send scheduling information used to determine the radio resources carrying the broadcast and multicast services. In one design, the Node B may time division multiplex the data for the broadcast and multicast services and the data for the unicast services. The scheduling information may convey time unit(s) used for each broadcast or multicast service. In another design, the Node B may map the data for the broadcast and multicast services to time frequency blocks. The scheduling information may (i) convey the time frequency block(s) used for each broadcast or multicast service or (ii) point to control information conveying the time frequency block(s) used for each service.

摘要： Methods, apparatuses, and computer program products are disclosed for facilitating a radio link failure determination. A wireless terminal is configured to monitor a control channel quality of a control signal over at least one control carrier. A radio link failure determination is then made based on the control channel quality of the at least one control carrier. In other embodiments, rather than basing the radio link failure determination solely on the set of control carriers, the wireless terminal is configured to monitor a control channel quality over at least one additional carrier, not included in the set of control carriers, in response to a link loss detected over each of the set of control carriers. For such embodiments, the radio link failure determination is then made based on the control channel quality of the additional carrier(s).
