Abstract :
The problem of optimal dynamic rate and power adaptation for forward link data transmission using high-order modulation and multicode formats in cellular WCDMA networks is formulated as a constrained optimisation problem. Based upon this formulation, a combination of exhaustive search (over all the possible allocations of modulation order) and linear programming is used to obtain the upper bound on the achievable radio link level throughput.
