N2 - When a user in Beyong third generation (B3G) mobile communication systems launches multiple applications simultaneously, the user's radio resources (subcarriers, symbols, power,⋯) need to be efficiently allocated to these applications while maintaining their quality of service (QoS) requirements and user utility. In this paper, a power minimization subcarrier, symbol, and power allocation problem is formulated, solved, and algorithms are derived. The problem formulation differs from those in existing works in that all the applications are from the same user. This relaxes some subcarrier allocation constraints that exist in multiuser single-application-per-user cases, leading to different solution techniques. Furthermore, the multiuser diversity which is the basis for many existing algorithms does not exist in the context of this paper.
