Abstract:
For the resource allocation problem in a multiuser OFDMA system, we propose an interactive communication scheme between the base station and the users with the assumption that this system utilizes a rateless code for data transmission. We describe the problem of minimizing the overhead measured in the number of bits that must be exchanged required by the interactive scheme, and solve it with dynamic programming. We present simulation results showing the reduction of overhead information enabled by the interactive scheme relative to a straightforward one-way scheme in which each user reports its own channel quality.
