摘要：

Since CDMA radio cellular system capacity is interference limited, power control and code allocation must be managed efficiently in order to control the interference and to guarantee the required quality of service of users. Power control is a key issue to improve system capacity. This paper analyses the problem of optimal power allocation in the uplink of a CDMA system supporting multiple services with distinct qualities of service like in UMTS. A way of finding the optimal power vector is shown. Single cell and multi-cell environments are discussed. The existence (or feasibility) of the optimal power solution is considered. A focus is made on the received power at the BS (base station) in the case of perfect power control.
