    摘要： Embodiments of the present disclosure describe methods, apparatus, and system configurations for coverage loss recovery in a wireless communication network. A method includes receiving, by a base station of a wireless communication network, a message from a mobile station that includes an indication that the mobile station is in coverage loss recovery, and a mobile station identifier to identify the mobile station. The method further includes determining whether a static context and/or a dynamic context associated with the mobile station identifier is stored at a previous-serving base station of the mobile station and transmitting a message to the mobile station to indicate which re-entry actions are to be performed to facilitate re-entry of the mobile station to the wireless communication network. Other embodiments may be described and/or claimed.

    摘要： A preemption system enables successful transmission of multiple service data units (SDUs) across a wireless interface. The preemption system addresses out-of-order transmissions of fragments of SDUs, such that the receiver is able to process each successfully. The preemption system enables a higher-priority SDU to simultaneously be transmitted with a lower-priority SDU, so that delays in processing the lower-priority SDU does not negatively affect processing of the higher-priority SDU. The preemption system also addresses non-automatic repeat request medium access controller (non-ARQ MAC) connections that only use hybrid automatic repeat request (HARQ), in which the HARQ transmission may cause out-of-order delivery of SDU fragments.

    摘要翻译： 抢占系统能够跨越无线接口成功传输多个服务数据单元（SDU）。 抢占系统解决了SDU片段的无序传输，使得接收机能够成功地处理这些片段。 抢占系统使得较高优先级的SDU能够同时使用较低优先级的SDU进行传输，因此处理较低优先级的SDU的延迟不会对较高优先级的SDU的处理产生负面影响。 抢占系统还涉及仅使用混合自动重传请求（HARQ）的非自动重传请求媒体接入控制器（非ARQ MAC）连接，其中HARQ传输可能导致SDU片段的无序传送。

    摘要： In an Orthogonal Frequency Division Multiple Access communication system, the location of one- and two-dimensional bursts may be specified by specifying the starting location of the plurality of bursts. The length of a burst may then be determined by subtracting starting locations of successive bursts. In some embodiments, the number of bits needed to specifying the location of bursts may be reduced.

    摘要翻译： 在正交频分多址通信系统中，可以通过指定多个突发的起始位置来指定一维和二维突发的位置。 然后可以通过减去连续突发的起始位置来确定突发的长度。 在一些实施例中，可以减少指定突发位置所需的比特数。

    摘要： Briefly, in accordance with one or more embodiments, a subscriber station in sleep mode is capable of sending and/or receiving traffic during sleep mode without violating the delay requirements of best effort traffic. Moreover, a subscriber station is capable of remaining in sleep and may optionally only be awaken in the event there is data to be transmitted from the base station to the subscriber station and/or from the subscriber station to the base station. By implementing an always sleep and need based wake up arrangement, the power consumption of the subscriber station can be reduced.

    摘要： Techniques for determining a paging area of a paging group in a wireless communications network based on a value of one or more dynamically changing communication characteristics. In various embodiments, a paging area may be determined to reduce resource use in a wireless communication network supporting an idle mode of a mobile station. In one embodiment, the paging area may be determined based on a speed of a mobile station.
