N2 - Applying relaying concept to a Universal Mobile Telecommunications System (UMTS) mobile network is not a new idea, and many systems employing relaying capabilities have been suggested. The Power Control (PC), which is an important aspect of UMTS, can be applied in such a mobile system, either in a centralised or a distributed fashion. An increase in the system capacity is expected, when utilised in all system links, Single-Hop (SH) and multi-hop. This is because the PC allocates, to the transmitters, the minimum powers which satisfy the link quality criteria. In this paper we formulate the transmit powers of a relaying system. We then compare, in an example, the power convergence of an iterative PC to the solution provided by the suggested equations. The assumptions, which facilitate rendering the formulations to a linear set of equations, are analysed.
