Claim Text:
1. A method of scheduling a downlink packet, the method comprising: a real-time traffic scheduling operation comprising allocating a physical resource block (PRB) to a traffic flow, wherein the real-time traffic scheduling operation is performed on all pieces of real-time traffic, and the real-time traffic is transmitted by using a first transmission power in a downlink; and a non-real-time traffic scheduling operation comprising allocating PRBs remaining after allocation to the real-time traffic in the real-time traffic scheduling operation, to non-real-time traffic, wherein the non-real-time traffic is transmitted by using a second transmission power in the downlink, the second transmission power being an excess transmission power relative to the first transmission power, and not being used to transmit the real-time traffic, wherein the real-time traffic scheduling operation calculates a scheduling metric on all real-time traffic flows, wherein the real-time traffic scheduling operation and the non-real-time traffic scheduling operation are performed by using an excess channel gain and reception power required per bit.
