摘要： In a wireless communication system a method for combination transmission of packet data and low delay data. In one embodiment a parallel signaling channel provides a message to receivers indicating a target recipient of packet data. The message also identifies the transmission channels used for packet data transmissions. Each receiver may then selectively decode only packets where the message identifies the receiver as a target recipient. The data packets stored in a buffer are ignored if the target recipient is another mobile unit. In one embodiment, the message is sent concurrently with the data packet on a parallel channel. In one embodiment, the message is punctured into the high rate packet data transmission.

摘要： Techniques for puncturing symbols in a communications system are disclosed. S symbols are received for a frame having a capacity of N symbols, with S being greater than N. P symbols need to be punctured so that remaining symbols fit into the frame. A number of puncture distances, D1 through DN, are computed based on S and P. A particular number of symbol punctures is determined for each computed puncture distance. P1 through PN symbol punctures are then performed at the distances of D1 through DN, respectively. For a more even distribution of the symbol punctures, each of the distances D1 through DN can be selected to be greater than or equal to a minimum puncture distance Dmin defined as Dmin=└S/P┘, where └ ┘ denotes a floor operator. The symbol punctures at each computed distance can be performed together or distributed with symbol punctures at other distances. In the alternative, an accumulator is configured to wrap around after it has been incremented to a value of S, each increment being of size P. A symbol index is incremented by one each time the accumulator is incremented by P, until the symbol index exceeds the value S. The process is advantageously begun with a puncture. Each time the accumulator wraps around, another puncture is performed. As another alternative, puncturing can be combined with symbol repetition.
摘要翻译：公开了一种在通信系统中对符号进行穿孔的技术。对于具有N个符号的容量的帧接收S个符号，其中S大于N.P个符号需要被穿孔，使得剩余符号适合于帧。基于S和P计算多个穿刺距离D1至DN。针对每个计算的穿刺距离确定特定数量的符号穿孔。然后分别在D1到DN的距离处执行P1到PN符号穿孔。为了更均匀地分配符号穿孔，可以将距离D1至DN中的每一个选择为大于或等于定义为Dmin =└S/ P“的最小穿孔距离Dmin，其中└表示地板操作者。在每个计算距离处的符号穿孔可以一起执行或者以其他距离的符号穿孔分布。在替代方案中，累加器被配置为在已经增加到S的值之后包围，每个增量为大小P.每当累加器递增P时，符号索引增加1，直到符号索引超过值S.该方法有利地开始穿刺。每次蓄能器包裹时，都会进行另一次穿刺。作为另一种选择，穿孔可以与符号重复组合。

摘要： Embodiments disclosed herein address the need in the art for efficient management of grant, acknowledgement, and rate control channels. In one aspect, a list associated with a first station is generated or stored, the list comprising zero or more identifiers, each identifier identifying one of a plurality of second stations for sending a message to the first station. In another aspect, sets of lists for one or more first stations are generated or stored. In yet another aspect, the messages may be acknowledgements, rate control commands, or grants. In yet another aspect, messages comprising one or more identifiers in the list are generated. Various other aspects are also presented. These aspects have the benefit of reduced overhead while managing grant, acknowledgment and rate control messaging for one or more remote stations.

摘要： Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.
摘要翻译：本文公开的实施例解决了本领域中需要减少开销控制的需要，其具有根据需要调整传输速率的能力。一方面，第一信号表示解码子包的确认，以及是否生成速率控制指令，第二信号在生成一个信号时有条件地指示速率控制指令。在另一方面，可以与确认同时产生许可。在另一方面，移动站监视第一信号，有条件地监视由第一信号指示的第二信号，并且可以监视包括授权的第三信号。在另一方面，一个或多个基站发射各种信号中的一个或多个。还提出了各种其他方面。这些方面具有提供基于授权的控制的灵活性的优点，同时在使用速率控制命令时利用较低的开销，从而提高系统利用率，增加容量和吞吐量。
