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： Systems and methodologies are described that facilitate identifying a plurality of keysets utilized in a communications network. The keysets can include ciphering keys that provide data encryption and decryption and integrity keys that provide data integrity protection. A key identifier can be included in a packet data convergence protocol header that indicates a keyset employed in connection with data in a protocol data unit. In addition, a route indicator can be provided in a radio link control header that distinguishes a source cell and a target cell in networks configured without RLC reset.

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.
摘要翻译：描述了在利用层（2）隧道传输进行切换期间发送数据的技术。在一种设计中，用户设备（UE）在切换到目标基站之前将第一层（2）分组发送到源基站。 UE向目标基站发送至少一个第二层（2）分组，其将第二层（2）分组标识为预期给源基站，并因此将第二层（2）分组转发给）通过层（2）隧道到源基站。 UE在切换后向目标基站发送第三层（2）分组。目标基站处理第三层（2）分组以获得IP分组并且在触发条件之后将该IP分组发送到服务网关，所述触发条件可以被定义为实现来自源和目标基站的IP分组的按顺序递送到服务网关。

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：在此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过程上的调度的反馈信号之前对HARQ过程进行多个传输，使得接收设备组合多个传输，而不是将它们视为单独的传输。以这种方式，可以使用多次传输来增加总体接收能量，而不会违反无线通信中的最大传输功率约束。此外，可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重传输，从而提供灵活的协议，其可在宽范围的无线条件下适应先进的以及传统的UE。

摘要： Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

摘要： This innovation relates to systems and methods for transmission of protocol data units, and more particularly to processing polling requests from a radio link control peer. A radio link control transmitter can poll a receiver to obtain a report regarding the status of a set of data packets, and the polls can be sent in-band with a data packet. The receiver can determine to wait before sending the status report based on one or more characteristics of the received data packets.

摘要： Apparatuses and methods of reducing overhead by designating various fields in an optimized Radio Link Control header. Depending on communication type (e.g., VoIP, non-VoIP) such fields include a combination of a Segment Indicator (SI - which indicates presence of a whole SDU at beginning or at an ending), a Sequence Number (SN), a Length Indicator (LI - which indicates length of a service data unit); a length for the length indicator (LLI - to enable a variable size for the LI and notify a receiver regarding such varying size); a Segment Offset (SO - to designate resegmented packets for lost protocol data units); a length indicator for the SO (LSO - to enable a variable size for the SO); and Last Segment Flag (LSF - for resegmentation of RLC protocol data units).

摘要： Systems and methodologies are described that facilitate employing a variety of medium access control (MAC) header formats in wireless communications. The MAC header formats can be specialized for a particular type of data included in a protocol data unit (PDU).

摘要： A wireless network avoids delays in receiving status reports by having transmitters make sure that any outstanding Hybrid Automatic Repeat-reQuest (HARQ) processes in progress are all finished before sending the polling request. Thus, the receiver can respond to any polling request of the transmitter immediately without delay. Since the transmitter already ensures all HARQ processes are done, the receiver's status report will accurately reflect the latest information. The transmitter may send a poll anytime regardless of the HARQ processes if the most up-to-date polling is determined to be not as important (e.g., when the transmitter is trying to advance its transmitter window, in which case the exact Status info is not critical). The receiver may then react immediate upon receiving the poll. Thereby, detecting the loss of any piece of data within a data burst is expedited.
摘要翻译：无线网络通过使发射机确保正在进行的任何未完成的混合自动重复请求（HARQ）进程都在发送轮询请求之前完成，从而避免接收状态报告的延迟。因此，接收机可以立即立即响应发射机的任何轮询请求。由于发射机已经确保所有HARQ过程完成，所以接收机的状态报告将准确反映最新信息。如果最新轮询被确定为不重要，则发射机可以随时发送轮询，而不管HARQ进程如何（例如，当发射机试图推进其发射机窗口时，在这种情况下确切的状态信息是不重要）。接收者可能会在接收到投票后立即作出反应。因此，加速了数据突发内的任何数据丢失的检测。

摘要： A method includes sending to a receiving device from a transmitting device a Radio Link Control (RLC) re-transmission scheme selected from a plurality of RLC re¬ transmission schemes, and using the selected and sent scheme at least at one of the receiving device and the transmitting device. In another exemplary non-limiting embodiment the method includes detecting, at the receiver, a gap in RLC Protocol Data Unit (PDU) sequence numbers, associating a timer with the gap, and starting the timer when the gap is detected. In still another exemplary non-limiting embodiment, the method includes detecting a gap in a RLC PDU sequence, monitoring a HARQ channel for a period of time to determine if a predetermined bit has changed, and determining if a transmission is lost.
