Wireless wideband multimedia services have been a “hot” topic the last few year with the advent of the so called 3rd Generation mobile communication system. Just by looking at the existing spectrum allocations for these types of systems, clearly shows that spectrum resource management remains an important topic in the near and distant future if these service are to reach a mass marked. In this paper, we start out by briefly reviewing the classical formulation of the radio resource management problem as found in 2G mobile telephony systems and some of the current approaches in the literature. We identify the three key allocation decisions we are concerned with: the waveforms(“channels”), the access ports (or base stations) and, finally, the transmitter powers. The principle of
random channel allocation
schemes, as found in frequency hopping or direct sequence CDMA systems, are compared with deterministic dynamic channel allocation schemes. The classical problem is then extended to a multi‐service setting were multiple quality‐of‐service requirements have to be met simultaneously. The paper closes by giving a more general outlook over some of the key problems in resource management in future wireless multimedia systems.
