Abstract :
The problem of efficiently allocating resources to high speed uplink packet access (HSUPA) users in a 3GPP network is studied. A discrete optimization problem is formulated in which user channel qualities and buffer sizes are used at the base station to jointly allocate uplink resources. To circumvent the possibility of local optima, a linearized version of this formulation is also presented. It is shown that knowledge of user buffer sizes can significantly improve the overall achievable bit rate.
