摘要： A system for communicating protocol layer processing information is disclosed herein. A transmitter includes a protocol layer header generator that generators a header for a first protocol data unit. The header generator provides a first header comprising a first sequence number field that determines the order in which a receiving entity present the first data unit to higher protocol layer. The sequence number field varies in length. A receiver includes a protocol layer header parser that parses a header of a first protocol data unit. The header parser parses a first header comprising a first sequence number field that determines the order in which the first data unit is presented to a higher protocol layer. The sequence number field varies in length.

摘要： Systems and methods for reduction of handover latencies in wireless communication systems are described herein. Some illustrative embodiments include a wireless mobile communication device that includes a wireless transceiver including a transmitter configured to transmit a first signal synchronized for reception by a first cellular node, and processing logic that couples to the wireless transceiver. Before the wireless transceiver receives a handover command the processing logic causes the transmitter to transmit a second signal for reception by a second cellular node to request allocation of an upload resource for communication with the second cellular node as part of an impending handover.

摘要： A novel and useful synchronization mechanism that functions to provide a uniform time base for mesh points in a WLAN mesh based network. The invention enables timing synchronization to a common reference clock base by advertising the common TSF within beacon transmissions. All MPs in a mesh share a common DTIM interval. The synchronization mechanism enables the mesh points to avoid collisions in the generation and transmission of beacons. The TBTT offsets of the current MP and its neighbors are advertised in beacons so that neighboring MPs that hear the beacons can select non-overlapping TBTT offsets. Each MP receives one or more beacons from its neighbors and compares the timing of its neighbors to that of itself and adopts the highest TSF (i.e. the fastest) in the mesh. Eventually, all MPs in the mesh will adjust their timing to that of the MP with the fastest clock. The reception of beacons by MPs from its neighbors is also advertised. This allows for MPs to verify that the beacons they send are actually heard and are not in collision with beacon transmissions of other MPs.
摘要翻译：一种新颖有用的同步机制，用于为基于WLAN网络的网络中的网点提供统一的时基。本发明通过在信标传输中通告公用TSF来实现与公共参考时基的定时同步。网格中的所有MP共享一个常见的DTIM间隔。同步机制使网格点能够避免信标的生成和传输中的冲突。当前MP及其邻居的TBTT偏移在信标中公布，使得听到信标的相邻MP可以选择不重叠的TBTT偏移。每个MP从其邻居接收一个或多个信标，并将其邻居的定时与其本身的定时进行比较，并采用网格中最高的TSF（即最快）。最终，网格中的所有MP将以最快的时钟调整MP的时间。接收来自其邻居的议员的信标也被广告。这允许MP验证其发送的信标实际上被听到并且不与其他MP的信标传输相冲突。

摘要： A transport block size (TBS) of a first uplink message (RACH Msg3) transmitted on a Physical Uplink Shared Channel (PUSCH) during a random access procedure in a User Equipment (UE) accessing a radio access network may be determined by receiving a pathloss threshold parameter. A downlink pathloss value indicative of radio link conditions between the UE and a base station (eNB) serving the UE is then determined. A smaller value of TBS is selected from a set of TBS values if the determined pathloss value is greater than an operating power level of the UE minus the pathloss threshold parameter. A larger value of TBS is selected if the pathloss value is less than the operating power level of the UE minus the pathloss threshold parameter and the TBS required to transmit the RACH Msg3 exceeds the smaller TBS value.
摘要翻译：在访问无线电接入网络的用户设备（UE）中的随机接入过程期间在物理上行链路共享信道（PUSCH）上发送的第一上行链路消息（RACH Msg3）的传输块大小（TBS）可以通过接收路径损耗来确定阈值参数。然后确定表示UE和服务于UE的基站（eNB）之间的无线电链路状况的下行链路路径损耗值。如果确定的路径损耗值大于UE的工作功率级别减去路径损耗阈值参数，则从一组TBS值中选择较小的TBS值。如果路径损耗值小于UE的工作功率级别减去路径损耗阈值参数，并且发送RACH Msg3所需的TBS超过较小的TBS值，则选择较大的TBS值。
