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 configuring a flush timer within a wireless environment in order to provide robust communications in regards to handover or re-establishment. The flush timer can be triggered upon successful completion of reconfiguration re-establishment. Moreover, the flush timer can be triggered upon successful completion of handover. In the case of handover and re-establishment, a separate indication of handover to packet data convergence protocol (PDCP) from the start of PDCP flush timer can be utilized.

摘要： The method and apparatus as described are directed toward techniques and mechanisms to improve efficiency in wireless communication networks through optimization of handover scenarios. Determining whether an intra-base station or inter-node-B handover is too performed, and determining the protocol layers to reset during the handover based at least in part on the type of handover to be performed increases the overall efficiency of the wireless network.

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： Systems and methodologies are described that facilitate managing interaction between paging and discontinuous reception (DRX) cycles for users operating in a communication system. As described herein, a connected mode user having an associated DRX cycle can modify its schedule for paging reception to minimize unnecessary periods of activity. For example, a user can initially schedule monitoring of paging occasions that coincide with periods of activity associated with the DRX cycle of the user. If such paging occasions are not sufficient to reach a minimum required number of monitored paging occasions, additional paging occasions can be monitored as needed by scheduling additional periods of activity and/or extending periods of activity specified in the DRX cycle. Additionally or alternatively, a network can synchronize a connected mode DRX cycle associated with a user with an idle mode paging cycle for the user, thereby providing power and performance benefits with low complexity.
摘要翻译：描述了便于管理在通信系统中操作的用户的寻呼和不连续接收（DRX）周期之间的交互的系统和方法。如这里所述，具有相关DRX周期的连接模式用户可以修改其用于寻呼接收的调度，以最小化不必要的活动周期。例如，用户可以初始地调度与与用户的DRX周期相关联的活动周期一致的寻呼时机的监视。如果这样的寻呼时机不足以达到所要求的最小监视寻呼时间的最小值，则可以根据需要监视附加的寻呼时机，以调度DRX周期中规定的活动的附加周期和/或延长的活动周期。另外或替代地，网络可以使与用户相关联的连接的模式DRX周期与用户的空闲模式寻呼周期同步，从而以低复杂度提供功率和性能优点。

摘要： Systems and methodologies are described that facilitate classification and identification of a channel associated with a wireless data transmission. As described herein, a channel designated for transmission of a packet can be selected from among multiple usable channels, based on which a bit at a predefined location in the packet can be set to a logical value indicative of the selected channel. As further described herein, extraction of the logical value from the predefined location and identification of the corresponding channel can be performed by a recipient of the packet without requiring parsing of the message. In one example described herein, a Dedicated Control Channel (DCCH) can be identified by setting a Logical Channel Identifier (LCID) bit in a DCCH packet to a predefined value. In another example, a Common Control Channel (CCCH) can be identified by embedding a Boolean constant within a message structure contained in a CCCH packet.
摘要翻译：描述了促进与无线数据传输相关联的信道的分类和识别的系统和方法。如本文所述，可以从多个可用信道中选择指定用于分组的传输的信道，基于该信道，可以将分组中的预定位置处的比特设置为指示所选择的信道的逻辑值。如本文进一步描述的，可以由分组的接收者从预定义位置提取逻辑值和对应信道的标识，而不需要解析该消息。在本文描述的一个示例中，可以通过将DCCH分组中的逻辑信道标识符（LCID）位设置为预定义值来识别专用控制信道（DCCH）。在另一示例中，可以通过在包含在CCCH分组中的消息结构内嵌入布尔常数来识别公共控制信道（CCCH）。

摘要： Certain aspects of the present disclosure provide a method for bearer count alignment during handover of a user equipment (UE) from a first radio access technology (RAT) to a second RAT. The UE establishes radio resource control (RRC) connections with the second RAT and transmits data radio bearer (DRB) capability of the UE to the second network. The second network utilizes this information to set up the DRBs with the UE.

摘要： In a wireless communication system, user equipment (UE) has autonomy provided by one or more set of rules to handle processing during a measurement gap. UE can ignore or use only a portion of the whole measurement gap if not needed. Thereby, an urgent need for remaining tuned to source carrier frequency can be supported, such as utilizing Random Access Channel (RACH) procedure. UE can also choose to tune to a target carrier frequency supporting timely handovers. Depending on the type of processing required (download shared channel (DL SCH, UL SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.
摘要翻译：在无线通信系统中，用户设备（UE）具有由一组或多组规则提供的自主权，以在测量间隙期间处理处理。如果不需要，UE可以忽略或仅使用整个测量间隙的一部分。因此，可以支持对源载波频率的保持调谐的迫切需要，例如利用随机接入信道（RACH）过程。 UE还可以选择调整到目标载波频率来支持及时切换。根据所需的处理类型（下载共享信道（DL SCH，UL SCH，TTI绑定，RACH或SR）），UE可以在间隙期间存储请求并处理测量结果，或者忽略差距测量，就好像没有间隙一样。

摘要： Explicit signaling of End of Handover (EoH) advantageously indicates when user equipment (UE) has stopped using Packet Data Convergence Protocol (PDCP) handover mode. Radio Link Control (RLC) Acknowledge Mode (AM) delivers in order ensuring that all reordered packets have been received with no risk of delivering a gap packet when no longer in handover mode that would otherwise cause Hyper Frame Number (HFN) to be out of synchronization. Substantially at a time evolved Base Node (eNB) determines a gap will not be filled, eNB can convey an EoH indication to a served UE and can then deliver the PDCP Service Data Units (SDUs) with gaps to upper layers without delay.
摘要翻译：切换结束（EoH）的显式信令有利地指示用户设备（UE）何时停止使用分组数据汇聚协议（PDCP）切换模式。无线电链路控制（RLC）确认模式（AM）提供以确保所有重新排序的分组已被接收，而不会在不再处于切换模式时递送间隔分组的风险，否则将导致超帧数（HFN）超出同步。基本上在演进的基站（eNB）确定间隙将不被填充的情况下，eNB可以向被服务的UE传达EoH指示，然后可以将具有间隙的PDCP服务数据单元（SDU）传送到上层，而不会延迟。
