Abstract: In a scheduling apparatus, a packet start time with respect to an input packet is calculated, and a slot corresponding to the packet start time is selected from a scheduler including a plurality of slots. Whether to store the packet in the selected slot in consideration of the number of packets stored in the selected slot and the number of packets corresponding to virtual ports corresponding to the input packet is determined, and here, the virtual port is an output port of a switch device which is connected to the outside and does not have a scheduling function.

Abstract: Provided herein is a communication method using MIMO (Multiple-Input Multiple-Output) technology for communicating with a terminal included in each of a plurality of base station cells using a communication apparatus, the method including calculating, by the communication apparatus, the number of terminals included inside a base station cell; generating, by the communication apparatus, pilot signals corresponding to the calculated number of terminals; and allocating, by the communication apparatus, the pilot signals to a terminal that may maximize a network capacity based on the generated pilot signals.
