Method and apparatus for using channel output feedback in multi user wireless systems and hybrid-ARQ

摘要

A method and apparatus for transmitting and receiving a signal using a channel output feedback in a wireless communication system and Hybrid-Automatic Repeat Request (ARQ) are provided. The method and apparatus include a transmitter configured to transmit to a base station and a first packet on a precoder received from the base station. A receiver configured to receive, from the base station, a Channel Output Feedback (COF) of the transmitted first packet and information for transmitting a second packet. A controller configured to prepare a variant of the second packet using the COF and the received information for transmitting the second packet, and to control to transmit the prepared variant to the base station.

1. A terminal for transmitting a signal using a channel output feedback, the terminal comprising:
a transmitter configured to transmit, to a base station, a first packet being applied a precoder received from the base station; a receiver configured to receive, from the base station, a Channel Output Feedback (COF) of the transmitted first packet and information for transmitting a second packet, wherein the information for transmitting the second packet is information on a channel state between the terminal and the base station determined based on a channel output of the transmitted first packet; and a controller configured to prepare a variant of the second packet using the COF and the received information for transmitting the second packet, and to control to transmit the prepared variant to the base station, wherein the COF of the transmitted first packet is a received signal of first packet received by the base station.
