    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： A system to protect MAC control messages is presented. In one embodiment, the system comprises a processor, a memory coupled to the processor, and a communication device coupled to the processor to communicate wirelessly over multiple sub-channels in an orthogonal frequency division multiple access (OFDMA) wireless network. The communication device is operable to determine that a MAC control message is protected if an indicator within the MAC control message is set. The communication device validates, if the indicator is set, integrity of the MAC control message in conjunction with a CMAC (cipher-message authentication code) tuple concatenated with the MAC control message.

    摘要： Short user messages can be conveyed in system management signaling for a data or telephony network. In one example, a first control message is sent from a first radio to a second radio, the control message including a data field, the data field containing a short message directed from a user of the first radio to a user of a third radio. In response, a second control message is received in reply to the first control message from the second radio, the second control message including a data field, the data field containing a response to the short message.
