In UklXS, four trafic classes have been identijied: conversational, streaming, interactive, and background, to jii&ll the QoS requests fiom the application or the user. To efectively manage the radio resources shared between these diferent QoS classes has become an important network planning issue. In this paper, the maximum available resource, R, , , of a cell @er sector per carrier) is defined in terms of the maximum downlink transmission power, the average propagation loss, the orthogonali& factor, and the other-to-own-cell intdeence ratio. The resource sharing factor of each trafic class can be calculated by dividing the total resource allocated for that class by the maximum available resource, R, , . f i e summation of the resource sharing factors of all traflc classes is smaller than one. This paper also shows that the average throughput of the downlink is a weighted sum of the resource sharing factors. Downlink throughput calculations for various traflc conditions with mixed QoS classes are presented by using the derived weighted sum equation.
