Patent ID: 8660094

Claim:
A method of transmitting data using a plurality of resources in a multi-antenna system, the method comprising: generating a plurality of modulation symbols by mapping encoded bits on a constellation by m (m>1) bits using a mapping rule in which a resource selection scheme and a modulation scheme are combined; generating a plurality of transmission symbols by performing spatial processing, according to a plurality of resources and a plurality of antennas, for the plurality of modulation symbols; and transmitting the plurality of transmission symbols through the plurality of respective antennas, wherein each of the plurality of modulation symbols on the constellation is generated based on the plurality of resources, corresponding to n (n≧1) bits of the m bits, by the resource selection scheme, and phase shift keying (PSK) of a 2 (m-n) order or quadrature amplitude modulation (QAM) of a 2 (m-n) order corresponding to (m-n) bits, by the modulation scheme, wherein the plurality of resources is a plurality of cyclic shift indices, wherein the plurality of resources includes a first cyclic shift index I cs1 and a second cyclic shift index I cs2 , wherein m=4 and n=1, and wherein the constellation is an 8-PSK constellation according to a following table: I cs1 I cs2 I Q I Q −1/{square root over (2)} −1/{square root over (2)} −1 0 −1 0 −1/{square root over (2)} −1/{square root over (2)} 0 1 −1/{square root over (2)} 1/{square root over (2)} 0 0 −1/{square root over (2)} 1/{square root over (2)} 0 1 0 −1 1/{square root over (2)} −1/{square root over (2)} 1/{square root over (2)} −1/{square root over (2)} 0 −1 1/{square root over (2)} 1/{square root over (2)} 1 0 1 0 1/{square root over (2)} 1/{square root over (2)}.
