Method and apparatus for information transmission in a radio communication system

摘要

A method of transmitting, by a transmitter, information in a wireless communication system, the method includes generating first and second symbols; generating first and second transmit vectors on the basis of an Alamouti code from the first and second symbols; and transmitting the first transmit vector through a first antenna and transmitting the second transmit vector through a second antenna. The first transmit vector consists of a first transmit symbol and a second transmit symbol. The second transmit vector consists of a third transmit symbol and a fourth transmit symbol. The first, second, third, and fourth transmit symbols are transmitted based on first and second resource indexes. The first symbol is a first modulation symbol for first information, and the second symbol is a second modulation symbol for second information.

1. A method of transmitting, by a transmitter, information in a wireless communication system, the method comprising:
generating first and second symbols; generating first and second transmit vectors based on the first and second symbols; and transmitting a first signal including the first transmit vector through a first antenna and transmitting a second signal including the second transmit vector through a second antenna, wherein the transmitting the first signal and the second signal is determined according to a transmission mode, wherein the transmission mode indicates either a single-antenna transmission or a multiple-antenna transmission, wherein the first transmit vector consists of a first transmit symbol and a second transmit symbol, and wherein the second transmit vector consists of a third transmit symbol and a fourth transmit symbol,wherein the first transmit vector and the second transmit vector is transmitted through each frame including a control region and a data region having a plurality of OFDM symbols.
