摘要： 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.

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.

摘要： The present invention relates to a wireless communication system that counts UEs using an MBMS, and a method thereof. The wireless communication system is connected with a UE through a radio link, and includes a Node B and a controlling radio network controller (CRNC). The Node B receives sequence setting information on a sequence included in a preamble transmitted from the UE from a network manager. The CRNC controls the Node B, detects a sequence according to whether to use an MBMS based on the sequence setting information, and performs a counting process for counting UEs based on whether the UE uses the MBMS. According to the present invention, counting of UEs using an MBMS can be efficiently performed by using a predetermined sequence. Particularly, the counting process can be simplified by reducing complexity in access probability management of a network manager, thereby increasing efficiency in data transmission by reducing signaling for random access probability and omitting a random access probability calculation process.
