Apparatus and method for transmitting and receiving control information in multi-hop relay broadband wireless communication system

摘要

An apparatus and method for transmitting control information to a Relay Station (RS) in a multi-hop relay broadband wireless communication system is disclosed. The apparatus includes a generator, a controller, and a communication unit. The generator generates control information to be transmitted to a lower RS. The controller controls and transmits the control information during a first relay link transmission interval among at least one relay link transmission interval distributed within a frame. The communication unit transmits the control information to the lower RS.
