摘要： A method and apparatus is provided for transmitting feedback information by each of user terminals in a communication system including the user terminals with different numbers of antennas. A multicast data packet is received from a base station through a downlink multicast transmission channel. If the multicast data packet has never been successfully decoded before, the multicast data packet is decoded and the success/failure in decoding the multicast data packet is determined. Upon the failure in decoding the multicast data packet, a NACK signal indicating the failure in decoding the multicast data packet is generated with sequences, the number of which is equal to the number of antennas of the user terminal. The NACK signal is transmitted to the base station through a shared feedback channel. If the user terminal has at least two antennas, sequences corresponding to the at least two antennas are orthogonal to each other and constitute sequence signals.

摘要： A bit/power loading method in an adaptive modulation-based multicarrier communication system computes ratios of modulation mode values to transmission power values sub-channel-by-sub-channel, selects a combination of sub-channels in which a sum of the ratios is maximized for a total number of bits to be simultaneously transmitted, and transmits signals in modulation modes corresponding to ratios of modulation mode values to transmission power values associated with the selected sub-channels. Because the bit/power loading method selects a combination of sub-channel modulation modes with the minimum total transmission power for a given number of bits on the basis of transmission power in each sub-channel modulation mode, the bits can be transmitted at the minimum transmission power in a given environment.
