Patent ID: 8743783

Claim:
A method for information transmission performed by a user equipment in a wireless communication system, the method comprising: obtaining a first resource index for a first antenna based on a channel control element (CCE) index related to a physical downlink control channel (PDCCH) and a parameter from a higher layer, obtaining a second resource index for a second antenna by adding an offset to the first resource index; determining a first information sequence based on a first cyclically shifted base sequence and a first orthogonal sequence; determining a second information sequence based on a second cyclically shifted base sequence and a second orthogonal sequence; transmitting the first information sequence via the first antenna; and transmitting the second information sequence via the second antenna, wherein the first cyclically shifted base sequence and the first orthogonal sequence are based on the first resource index, and wherein the second cyclically shifted base sequence and the second orthogonal sequence are based on the second resource index.
