ABSTRACT:
A joint scheduling apparatus and method for increasing frequency efficiency and fairness in a multi-channel distributed antenna system using frequency reuse and common control power. One of a Base Station (BS) or Relay Station (RS) are selected to transmit packets to a Mobile Station (MSs), taking into account Quality of Service (QoS) in one of a BS and an RS and grouped into packet groups. The packets are selected from the packet groups, links corresponding to the packets are grouped into a link group, a joint power control is performed on the link group, link elimination and link addition are performed for the link group until optimal solutions are achieved for the links group, channels are allocated to the links when the optimal solutions are achieved for the links, and the status of a user queue is updated.
