“…For instance, a UE measures the received power in the downlink pilot channel (e.g. CPICH [2]) to set its transmission power. Once the UE knows the received power of the pilot channel, P R pilot , and the total interference plus noise, I m , (broadcasted by the network), it can use these parameters to adjust the transmission power P T , according to the following equation:…”

Universal Mobile Telecommunication System (UMTS) isbased on WCDMA technology. The capacity of this system is difficult to manually compute because of at least two reasons. Firstly, this system is designed to support many types of services, and hence capacity calculation using classic Erlang's capacity is not sufficient. Secondly, the capacity of such system depends on interference which is a time-varying factor, so that it is necessary to precisely model the interference; otherwise the result may be inaccurate. This paper aims to provide complete details of uplink WCDMA modeling and simulation. This proposed simulation is a dynamic system-level simulation in which important parameters such as radio propagation effects, user movement, power control and interference modeling are included. The principles of WCDMA modeling and simulation which are presented in this paper are essential tools for study and research in optimising UMTS system.

The TDD operation mode of UMTS allows highly dynamic and various configurations of the physical layer time frame. A key issue in developing access methodologies to the available spectrum is an optimal management of the rare radio resources. In this papel; the application of interference based dynamic resource allocation is evaluated and compared to fixed channel allocation. The allocation dynamic bases on an attempt to offer connections instantaneous quality of service. Moreover; it allows rearrangement of the allocated resources in order to increase connection quality in case of a possible impending connection breakdown. As a decentralised algorithm, dynamic channel allocation offers among its performance gain the ease of implementation while reducing network planning.
