Resource allocation is performed in a shared wireless network that includes multiple cells, a shared wireless network QoS manager, and multiple local QoS managers. The shared wireless QoS manager receives from multiple ones of the local QoS managers on a per cell and per QoS service class basis (for a plurality of QoS service classes): an aggregation of current cell usage estimations; an aggregation of cell load level indicators, and an aggregation of additional resources needed. Using this received information, the shared wireless network QoS manager: determines a total capacity of each cell that is needed to satisfy a total resource need on a cell by cell basis for the local QoS managers; and based on a maximum capacity for each cell, allocates to each local QoS manager a percentage of their total resource need.
