Abstract:
1. A method for use in a subscriber unit for providing data transmissions to a base station in a wireless communication network, the method comprising: receiving a plurality of allocated channels from the base station, wherein at least one of the plurality of allocated channels is used for data transmissions; encoding a data signal using a data encoding scheme optimized for data transmissions, wherein the data encoding scheme uses an encoding different than the encoding used for a voice signal, wherein a number of the plurality of allocated channels changes during the transmission of the data signal; and modulating the encoded data signal such that the modulated bandwidth and power spectrum of the encoded data signal are optimized for data transmissions, wherein the modulated bandwidth and power spectrum of the encoded data signal is the same as the modulated bandwidth and power spectrum for a modulated voice signal; and transmitting the modulated data signal; wherein the plurality of allocated channels are allocated on an instantaneous basis, and wherein the plurality of allocated channels are allocated based on the demands of the data transmissions.
