Patent ID: 8422451

Claim:
A method for transmitting a sequence to a Node-B by a user equipment (UE), the method comprising: applying a circular shift (CS) with a CS value from among a plurality of CS values to a basic sequence, wherein the basic sequence is generated using a basic sequence index received from the Node-B, and wherein the plurality of CS values are correspond to a multiple of a length related to a ZCZ (Zero Correlation Zone) value; and transmitting the CS applied basic sequence to the Node-B, wherein the CS applied basic sequence was matched to an extended random access channel structure before the transmission, wherein a normal random access channel structure and the extended random access channel structure have a cyclic prefix part and a sequence part, and wherein at least one length of the cyclic prefix part and the sequence part of the extended random access channel structure is longer than at least one corresponding length of the cyclic prefix part and the sequence part of the normal random access channel structure.
