priority queues 261 263 is filled with data packets for a particular mobile station also effects the scheduling of that user in case of real time traffic user the data packets stored in the queue should be sent very soon i e with minimum delay the queue type also affects this determination high priority queue 261 always gets first preference over medium priority queue 262 and low priority queue 263 d ap u2014 available power u2014 bts 210 determines the power available for scheduling a particular mobile station application according to an advantageous embodiment of the present invention bts 210 is capable of transmitting using different modulation schemes that require different levels of power hence the available power should be considered before allocating and scheduling a particular mobile station application e cfb u2014 c i feedback u2014 the c i feedback provided by the mobile station to bts 210 determines the air link quality if a first mobile station has a better wireless link quality i e less fading and noise than other mobile stations then that first mobile station has higher priority in cdma2000 ev dv schemes there is a channel quality feedback channel in which mobile stations transmit the c i feedback data from which.
