Abstract: When a plurality of terminals share the same resources in a wireless communication system, and when control information such as acknowledgement/negative acknowledgement (ACK/NAK) information or scheduling information is transmitted, a method of efficiently performing code division multiplexing (CDM) is required to distinguish the plurality of terminals. In particular, it is necessary to develop a method by which a code sequence of CDM can be selected and used according to each cell condition. Provided is a method of forming a signal in a wireless communication system in which a plurality of terminals commonly share frequency and time resources. The method includes the operations of receiving condition information in a cell; selecting one of a plurality of time domain orthogonal sequences having different lengths, according to the condition information; and allocating the selected time domain orthogonal sequence to a control signal symbol block.

Abstract: A first terminal generates a first scheduling request signal including information about first data resources for data transmission when the first terminal tries to reserve the first data resources. The first terminal generates a first scheduling request indication signal providing notification that the first scheduling request signal is to be transmitted. The first terminal transmits the first scheduling request indication signal through a first request subslot included in a first scheduling request resource before transmitting the first scheduling request signal. The first terminal transmits the first scheduling request signal through a second request subslot included in the first scheduling request resource.
