Abstract  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.
