Abstract: A "time multiplexed" transmission scheme capable of reducing the amount of interference from other cells operated at the same frequency band. Each cell of a system transmits in designated time intervals (e.g., time slots) during which other interfering cells may be prevented from transmitting. By temporarily "blanking" transmissions from interfering cells during the designated time slots, the amount of interference from these cells is reduced. The improved signal quality may support transmission at a desired or higher data rate, which may not be possible without cell blanking. In one variant, transmissions from the cells are staggered over different time slots. A set of one or more cells may be designated to transmit in each of a number of slot phases. The cells transmit in a staggered manner on theses phases to reduce interference. The transmission scheme may be used for a various channel types (e.g., a control channel) and applications.

Abstract translation: “时分复用”传输方案能够减少在相同频带上工作的其他小区的干扰量。 系统的每个小区以指定的时间间隔（例如，时隙）发送，在该时间间隔期间可以防止其他干扰小区的发射。 通过在指定时隙期间暂时从干扰小区“消隐”传输，减少了来自这些小区的干扰量。 改进的信号质量可以支持以期望的或更高数据速率的传输，这在没有小区消隐的情况下可能是不可能的。 在一个变型中，来自小区的传输在不同的时隙上交错。 可以指定一组一个或多个小区在多个时隙相位中的每一个中进行发送。 小区在这些相位上以交错的方式发送以减少干扰。 传输方案可以用于各种信道类型（例如，控制信道）和应用。

Abstract: Transmitter and receiver units for use in an OFDM communications system and configurable to support multiple types of services. The transmitter unit includes one or more encoders, a symbol mapping element, and a modulator. Each encoder receives and codes a respective channel data stream to generate a corresponding coded data stream. The symbol mapping element receives and maps data from the coded data streams to generate modulation symbol vectors, with each modulation symbol vector including a set of data values used to modulate a set of tones to generate an OFDM symbol. The modulator modulates the modulation symbol vectors to provide a modulated signal suitable for transmission. The data from each coded data stream is mapped to a respective set of one or more "circuits". Different circuits can be used for full rate data (e.g., active speech) and low rata data (e.g., silence periods).

Abstract: An original data stream is encoded into a high priority data stream and a low priority data stream. The high priority data stream is encoded so as to permit decoding of the high priority data steam independently of the low priority data stream. The high priority data stream is transmitted twice, while the low priority is transmitted in two portions, but only once. If both the first portion and the second portion of the low priority data stream are received, and at least one complete transmission of the high priority data stream is received, then the two data streams are combined to "produce a signal output of high quality. However, if any portions of the low priority data stream is lost' then the low priority data stream is not used, and only the high priority data stream is used to produce output. Overall throughput is greater than would be achieved if the original data stream were transmitted with complete redundancy.

Abstract: A satellite communication system designed to communicate with wireless communication devices (WCDs) by use of a mosaic pattern of signal beams uses multiple beams to augment the communication with individual WCDs. In addition to communication with a WCD through a primary beam for that WCD, adjacent beams are used, but with signals utilizing circuit parameters assigned to the primary beam. The signals from a given WCD are relayed in a backhaul, either as an aggregate signal processed by the satellite, or as backhaul communication signals to be combined or separated on the ground.

Abstract: Orthogonal CDMA (OCDMA) in the return link of a satellite based communications system provides improved bandwidth efficiencies; increased ability to overcome channel degrading phenomenon; reduced transmission power; or various combinations thereof. By achieving code synchronization needed for advantageous use of OCDMA in the return link of a satellite based communication system, a plurality of terminals, each with a unique time slot/code channel assignment, may transmit concurrently, with the same, or lower, aggregate power as would be used by a single terminal using TDMA. Use of OCDMA in the return link allows one or more terminals, each in a common beam and assigned a common time slot, to transmit at a higher transmission power to overcome channel degradation effects. The ability to allow for higher transmission power for a particular terminal can increase the effective data rate for that terminal by enabling the use of a higher order modulation technique.

Abstract: In a CDMA data communication system capable of variable rate data transmission, a time-division power assignment cyclically reduces the carrier power level to at least one sector to reduce interference in neighboring sectors. The base station determines a time-division power assignment for each sector and generates signals according to the power assignment. The mobile unit (700) generates filter coefficients corresponding to each power level. The mobile unit estimates Carrier Signal-to-Interference (C/I) to determine a data rate for each power level. Previous iterations of the equalizer (710) are stored and used to refine future estimates.
