Abstract: System and method for transmitting data over a communications link in at least two channels. At least one transmitter transmits data in the two channels simultaneously. At least one interleaver interleaves data to be transmitted in the two channels prior to transmission by the at least one transmitter. The at least one interleaver employs different sets of interleaving parameters when interleaving data to be transmitted in different channels, such that data to be transmitted in each channel is interleaved in a different pattern than data to be transmitted in the other channel(s). At least one receiver receives the data transmitted in at least one of the two channels. A de-interleaver, associated with the at least one receiver, employs the set of interleaving parameters corresponding to the at least one channel received by the at least one receiver to de-interleave data received by the at least one receiver.

Abstract: A novel communication channel structure and method in a wireless communicati on system is provided. In an embodiment of the invention, the communication system includes a base station and a plurality of subscriber stations and the subscriber stations are given access to a variety of channels, including at least one uplink data channel. The uplink data channel can operate in at least a random access mode and a polled access mode. The base station informs each subscriber station it serves of the current mode of the uplink channel via an associated downlink signaling channel and, in random access mode, each subscriber stati on is able to randomly access the shared uplink channel. In polled mode, each subscriber station waits for permission from the base station before sending data over the shared uplink channel. A method of operating the system monitors the collisions which occur on the uplink channel in random mode and/or the amount of data and/or the data's priority level and/or QoS requirements and switches the system between random and polled modes as appropriate. In polle d mode, the method determines which subscriber stations should access the uplink and whe n.

Abstract translation: 提供了一种无线通信系统中的新型通信信道结构和方法。 在本发明的一个实施例中，通信系统包括一个基站和多个用户站，并且用户站可以接入包括至少一个上行链路数据信道的各种信道。 上行链路数据信道可以至少以随机访问模式和轮询访问模式操作。 基站通过相关联的下行链路信令信道向每个用户站通知它服务的上行链路信道的当前模式，并且在随机接入模式下，每个用户站能够随机接入共享上行链路信道。 在轮询模式下，每个用户站在通过共享上行链路信道发送数据之前等待来自基站的许可。 操作系统的方法监视在随机模式中在上行链路信道上发生的冲突和/或数据量和/或数据的优先级和/或QoS要求，并且在适当的时候在随机模式和轮询模式之间切换系统。 在轮询模式下，该方法确定哪些用户站应该访问上行链路以及何时。
