Abstract: Disclosed is a method of integrating voice and data services onto a sam e frequency channel using available transmit power information to determine da ta rates, wherein the available transmit power information indicates an amount of transmit pow er available for future data transmissions over one or more data channels. In a "distributed" embodiment, a transmitter or base station transmits. via a forward link, an available powe r message to a receiver or mobile-telephone indicating an amount of available transmit power at some future time t+z. The mobile-telephone performs signal-to-interference measurements corresponding to the received forward link and received interference, and uses such signal-to- interference measurements and the available power message to determine a data rate that c an be supported by the mobile-telephone. Preferably, the determined data rate corresponds to a maximum data rate at which a minimum level of quality of service can be achieved at the mobile- telephone. In a "centralized" embodiment, the mobile-telephone transmits the signal-to- interference measurements to the base station, and the base station determines the data rate based on the available transmit power at future time t+z.

Abstract: The present invention is a method for outputting larger bit size pseudo-random number zi that is cryptographically secure. Since larger bit size pseudo-random numbers are being outputted, larger bit size segments of messages may be encrypted resulting in a speedier encryption process than encryption processes of the prior art. In one embodiment, the present invention is a pseudo-random number generator defined by a modular exponential function xi = g <>i-1 mod p. The output of the pseudo-random number generator being a pseudo-random number zi comprising a j-1 bit size segment of xi. The value of j being less than or equal to m-2c (i.e., j≤m-2c). In an embodiment of the present invention, the pseudo-random number zi includes the j least significant bits of xi excluding the least significant bit of xi.

Abstract: The present invention is a method for outputting larger bit size pseudo-random number z; that is cryptographically secure. Since larger bit size pseudorandom numbers are being outputted, larger bit size segments of messages may be encrypted resulting in a speedier encryption process than encryption processes of the prior art. In one embodiment, the present invention is a pseudo-random number generator defined by a modular exponential function xi = g xt-i mod p . The output of the pseudo-random number generator being a pseudo-random number zi comprising a j-1 bit size segment of xi. The value of j being less than or equal to m-2c (i.e., j~m-2c). In an embodiment of the present invention, the pseudo-random number zi includes the j least significant bits of xi excluding the least significant bit of xi.

Abstract: The capacity of a reverse link is improved by realizing a scheme to effect sharp changes in pilot channel transmit power (PCTP) and data channel to pilot power ratio (DCPR), coordinated with the start of the data channel transmission. The change in pilot power and data channel to pilot power ratio is also applicable to mobiles that use multiple pilots and/or multiple antennas at the transmitter and/or receiver.
