    Abstract: A method for providing power control with variable data rate, the method comprising: receiving a data frame having an input data rate selected from a plurality of possible input data rates; selecting an encoding rate based on the input data rate; encoding data frames to produce output symbols, repeating output symbols using first and second generating polynomials and multiplexing the repeated output symbols, selecting a puncturing format to puncture data bits and producing output data having a constant output data rate for a number of possible input data rates based on a combination of input data rates, selected encoding rate and selected puncturing format for providing said variable data rate communication link; determining a frame error rate for a number of possible input data rates; calculating differences between the frame error rates and a target error rate and adjusting the power depending on whether the difference is greater, equal or less than a predetermined threshold.

    Abstract: An apparatus according to one embodiment of the invention includes a transmitter. The transmitter receives an RF signal and produces at least two modulated signals based on the RF signal. Each of the modulated signals is coupled to a respective antenna. The combined radiation pattern of the antennas varies in an angular direction over time. In a system according to one embodiment of the invention, a base station including such an apparatus receives channel quality indications from mobile units and schedules data transmissions to the mobile units accordingly.

    Abstract: The present invention is a method and apparatus for integrating a personal communication system with a cable television plant. A set of radio antenna devices (RAD) are connected to the cable plant. The RADs provide frequency conversion and power control of signal received from the cable plant for wireless transmission to the remote units. The RADs also provide power control and frequency conversion of wireless signals received from the remote units for transmission by the RADs onto the cable plant. In addition to the functions of standard base stations and centralized controller, the CATV base station must also compensate for gain variations in the cable plant. The downstream power control is regulated by a RAD reference signal which can be hidden within the CDMA signal for maximum efficiency. The upstream power control is regulated by an upstream gain reference signal which is individually transmitted by each RAD on the upstream link. The architecture of the present invention lends itself to a great deal of flexibility. Each RAD can operate as either an element of a distributed antenna or a base station sector unto itself. The function of each RAD as distributed antenna or as sector can be remotely programmed from the headend processor. Thus the capacity density of the system can be changed to accommodate the changing traffic density. The flexibility also is important at system deployment. When the system is deploy, the entire system may feed only one sector at the base station thus reducing the start-up cost of implementing a system. As system traffic increases, more resources can simply be added at the headend to provide more capacity.

    Abstract: A cellular communication system in which a system user and another user communicate with each other by way of information carrying spread spectrum modulated signals transmitted via a cell-site in which system: the system user comprises a transmitter for transmitting information carrying spread spectrum modulated signals to said cell-site, a receiver for receiving information carrying spread spectrum modulated signals from said cell-site and means for measuring signal quality in said information carrying spread spectrum modulated signals received by the system user; the cell-site comprises a transmitter for transmitting information carrying spread spectrum modulated signals to said system user, a receiver for receiving information carrying spread spectrum modulated signals from said system user and adjusting means for adjusting the power of information carrying spread spectrum modulated signals transmitted from the cell-site ; ; and power control means is provided for controlling the transmission power of the information carrying spread spectrum modulated signals by measuring the signal power in the information carrying spread spectrum modulated signals received by the system user and transmitting data representing the measured power to the cell-site by way of the information carrying spread spectrum modulated signals, the adjusting means being responsive to the data in the information carrying spread spectrum modulated signals from the system user to adjust the power in the information carrying spread spectrum modulated signals transmitted by the cell-site.

    Abstract: A method and apparatus for providing diversity transmissions to a mobile unit from a transmitting station having at least first and second antennas by repeatedly switching between the two antennas during the transmission of information to the receiving unit. Message information is transmitted from the first antenna in the transmitting station to the receiving unit. After the start of the transmission of the message information from the first antenna, transmission of the message information from the first antenna to the receiving unit terminates and transmission of the message information from the second antenna in the transmitting station to the receiving unit is initiated. Some time after transmission of the message information from second antenna is initiated, the transmission of the message information from the second antenna to the receiving unit terminates and transmission of the message information from the first antenna in the transmitting station to the receiving unit is initiated. Repeated switching between the first and second antennas is achieved by repeating the process. The switching results in diversity transmissions that improve the ability of a receiving unit to receive the coded and interleaved transmitted message information from the transmitting station. The interleaver disperses the encoded symbols in each antenna dwell period such that the decoder decisions are based on a mix of symbols form each antenna. Therefore the decoder decisions are unreliable only when the mix of symbols from the different antennas, with different fading characteristics, are unreliable over the span of symbols the decoder uses in its decision process.
