Abstract: A method for releasing resources allocated by persistent scheduling is described. A base station (BS) inserts a persistent allocation release indication message into a control channel, wherein the persistent allocation release indication message includes at least one resource index indicating persistent allocation resources to a mobile station (MS), broadcasts the control channel, and releases the persistent allocation resources corresponding to the resource index. Since a release message for persistent allocation, a channel quality indicator channel, feedback polling allocation, etc. is inserted for transmission into a control channel which can be received by all MSs, overhead which occurs during resource release can be minimized irrespective of transmission rates varying with MSs.

Abstract: A method of transmitting feedback information is disclosed. More specifically, a mobile station (MS) receives a Protocol Data Unit (PDU) which includes a Medium Access Channel (MAC) header from a base station (BS).
