    • A method for managing data traffic in a multi-user multiple-simultaneous-access (MUMSA) environment, for example in a code reuse multiple access (CRMA) environment or other physical environment having true random access with more than one transmission present at the same time, the method including estimating channel load for multiple users, then using the estimate of channel load to calculate a congestion threshold on an ongoing basis, at each terminal performing an experiment using that congestion threshold value and a random number generator to determine if a packet is eligible to be transmitted, transferring downstream virtual channel traffic and redistributing user terminals to affiliate with the proper downstream virtual channel.

    • This invention is a multiple access communication technique by which a multitude of transmitters communicate with receivers using direct sequence spread spectrum signaling. The direct sequence codes are reused by a large number of simultaneous transmitters, so the system is named Code Reuse Multiple Access (“CRMA”). This reuse method requires only a small number of codes relative to the number of simultaneous transmitters, and can use as few as one code for all the users. The direct sequence codes are not required to have special properties such as maximal length. The lengths of the spreading codes employed are not necessarily related to the bit or symbol interval. CRMA can be implemented on a Paired Carrier Multiple Access (“PCMA”) system with or without a novel receiver structure which is also described.

CRMA can be implemented on a Paired Carrier Multiple Access (“PCMA”) system with or without a novel receiver structure which is also described. In an environment having virtual channels, a clock is derived from the received signal in the uplink by sampling the signal to detect symbol edges.

    • A method for managing data traffic in a multiple-user multiple simultaneous access environment using a channel load estimate and a calculation. The estimate or estimates are used to calculate a congestion threshold (CT) and to select a current congestion threshold broadcast to all potential users. An experiment is performed by users comparing that congestion threshold value and a random number to determine if a packet is eligible to be transmitted, thus throttling the random transmission of packets so that the transmitted load from the terminal has a rate of packet transmission that is less than the congestion threshold times the offered load (from the user), where the congestion threshold value is related to the probability of a globally successful transmission of a number of simultaneously transmitted packets. A quality of service (QOS) factor may also throttle the transmitted load.
    • 一种用于使用信道负载估计和计算来管理多用户多个同时访问环境中的数据业务的方法。 估计或估计用于计算拥塞阈值(CT)并选择向所有潜在用户广播的当前拥塞阈值。 用户进行实验,比较拥塞阈值和随机数,以确定分组是否有资格发送,从而节制分组的随机传输,使得来自终端的传输负载具有较小的分组传输速率 比拥塞阈值乘以所提供的负载(来自用户),其中拥塞阈值与全球成功传输多个同时发送的分组的概率相关。 服务质量(QOS)因素也可能会削弱传输的负载。
