Abstract
Official abstract text for this publication.
A system for wireless data transmission that uses a channel bandwidth, channel separation, and radio frequency power spectrum which is compatible with existing deployments of wireless voice services. The transmitted waveforms are thus compatible with existing cellular networks. However, the time domain digital coding, modulation, and power control schemes are optimized for data transmission. Existing cellular network sites can thus be used to provide a high speed service optimized for wireless data traffic without the need for new radio frequency planning, and without interfering with existing voice service deployments.
First claim
Opening claim text (preview).
What is claimed is: 1. A code division multiple access (CDMA) subscriber unit comprising: circuitry configured to receive a forward link CDMA code channel and a forward link packet data channel; wherein the forward link packet data channel has a varying number of CDMA codes; wherein the circuitry is further configured to transmit a reverse link CDMA code channel and a reverse link packet data channel; wherein the reverse link packet data channel has a varying number of CDMA codes.…
