Abstract: A method for allocating data rate to a stream of information to be transmitted over a communication channel of a communication system is provided. Modified union bounds are used to determine the channel characteristic experienced by each of the streams to select their respective data rates from an MCS that can be handled by the communication channel of the communication system.

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: A communication system's transmit configuration is reconfigured based on mobile station associated conditions such as the capability of the mobile receiver, carrier to interference or signal to noise ratios, and the degree of mobility associated with the mobile station. As a result, the transmit configuration is optimized for the conditions associated with a particular mobile receiver. In one embodiment, the transmit configuration may be selected to operate in configurations such as a single transmit antenna configuration, a space time spreading configuration, a selective transmit diversity, and a multi-output and multi-input configuration.

Abstract: A transport channel multiplexing system provides improved use of wireless resources in a shared data channel system. For example, the transport channel system reduces the amount of transport format information required for using a shared data channel, such as the actual number of packet data units in a transport channel of the shared data channel. Additionally, by scheduling or multiplexing coded sub-blocks from one or more transport channels over the shared data channel, the transport channel multiplexing system can provide improved integration with other important features, such as incremental redundancy, fast adaptation to channel conditions and transport channel dependent quality of service (QOS) control, to provide improved system performance.
