Abstract: Method for Processing Shared Sub-packets in a Communication System are disclosed. A communication system providing both voice and data services allows for a plurality of subscriber station to share a data sent in a unit of a forward traffic channel. To provide information required by the subscriber stations to determine that a unit of the forward traffic channel is shared, and to correctly decode the data, different control channel structures are described, e.g. F_SPDCCH. Additionally, the control channel structures provides for more efficient signaling of code channel assignment.

Abstract: A method and apparatus for variable rate communication incorporating coherent signal processing and combining is described. Within the receive system, vectors of in-phase and quadrature-phase Walsh correlator output values are generated for each Rake finger over each Walsh symbol period. In-phase and quadrature-phase reference values are generated for each of the Rake fingers by combining the in-phase and quadrature-phase correlator outputs of the most likely Walsh symbols over a series of Walsh symbol periods. The output energies are calculated as the sum of squared in-phase and quadrature-phase values. The vectors of in-phase and quadrature-phases values are then projected on the in-phase and quadrature-phase reference values and weighted by the reference amplitude. The reference amplitude is the square root of the sum of squared in-phase and quadrature-phase values. The vectors of projected and weighted values are summed via coherently combining, and the corresponding values from the other Rake fingers used to obtain a resultant vector of coherently demodulated Walsh correlator outputs.
