摘要： The present invention provides a method of coordinating transmission by and reception by a plurality of antennas associated with a plurality of radio heads. The method includes determining, at a controller, at least one relative time delay associated with a plurality of backhaul links between the controller and the plurality of radio heads. The method also includes providing information indicative of a first signal over the plurality of backhaul links. The method further includes providing timing information over the plurality of backhaul links. The timing information is determined based on the relative time delay(s) such that the plurality of radio heads can use the provided timing information to coherently transmit the first signal using the plurality of antennas and a plurality of controllers to receive mobile unit transmitted information.

摘要： A low-cost, low-power, low-complexity, small, high-reliability, robust, seamless satellite communication network is described. The network performs encoding of a user signal at the customer premises to enable routing of the user signal to an appropriate destination beam at the satellite requiring low power user signal processing. Routing information is embedded at the periphery of the network CPE's rather than at the satellite. Embedding the routing information in this way greatly reduces on-board switching complexity and increases signal to interference ratio for the user.

摘要： A method and apparatus are provided for dynamically controlling a high speed wireless communication system to optimize utilization of system resources and thereby increase system throughput. The invention operates to determine an allocation of wireless transmission resources to each user application served by the wireless system in a manner to optimize transmission resources while meeting required QoS criteria for the served user application. After all user applications have been provided a transmission resource allocation in this manner, the total transmission resources so allocated are determined and compared with a ceiling transmission resource level for the wireless system. A portion of the difference between the ceiling and currently allocated transmission resource levels is then made available, according to the invention, to the served user applications in proportion to the initial allocation provided each user application.

摘要： In accord with the transmission system, encoded signals may be processed in intermediate stations and at receiving stations in an order different from the order of the original encoding process for transmission. In particular, the recovery of CDMA encoded signals does not require application of spreading/despreading codes in the original scheme or sequence of application of spreading codes. In one embodiment, code applications may be permuted without losing the original signal which has been encoded. In such applications, not all of the encoding spreading functions results in an increased spreading rate.
摘要翻译：根据传输系统，编码信号可以在不同于用于传输的原始编码过程的顺序的中间站和接收站处理。特别地，CDMA编码信号的恢复不需要在扩展码的原始方案或应用序列中应用扩频/解扩码。在一个实施例中，代码应用可以被置换而不丢失已被编码的原始信号。在这种应用中，并不是所有的编码扩展功能都会增加扩展速率。

摘要： A cellular network includes a control station and a network of base stations installed one per cell with which one or more mobile stations can communicate as they roam through a cell. Redundantly deployed spare base stations are introduced along with the primary base station at a central area of each cell. The redundantly deployed spare base stations handle new calls when the associated primary base station is overloaded, participate in retransmission of data lost due to degraded channel conditions and congestion in the network, and assist in handoffs. Primary and spare satellite stations are deployed in regions marked by hills or valleys to augment the communicative capabilities of the primary and spare base stations.

摘要： A telephone signaling system is operative outside of the traditional calling and data transmission paths to provide originating to termination signaling. Routing of the signaling is in response to a locator system which includes a data base of terminations and a system for keeping up to date information of current termination locations of the intended recipient. In one illustrative embodiment the termination equipment includes locator devices such as GPS locating devices. The information supplied by the GPS locating device is provided to a central data base which routes the signaling system to the intended recipient termination device. The central routing system then selects a voice and data transmission path that optimizes some preselected criteria of transmission. A typical criteria could be cost, or bandwidth or some combination of criteria to be optimized.
