摘要:
The method for wireless resource subframe allocation comprises the following steps: allocation of the control channel based on the first RAT (Radio Access Technology) of the first control domain, which includes the OFDM symbol of the first number from the sub-frame containing multiple OFDM symbols and multiple subcarriers in the frequency domain; allocation of the control channel based on the second RAT of the second control domain including the OFDM symbol of the second number which follows said first control domain; and the allocation of a data channel in the data domain which includes the OFDM symbols positioned outside said first control domain and second control domain. This invention provides a sub-frame structure which is compatible with existing wireless communication systems. This method allows the continued use of existing control channel systems or base signal structures. The method is also capable of supporting advanced features.

The present invention relates to a wireless communication system, and provides an efficient control information transmission method and apparatus for supporting a multiple antenna transmission technique. According to one embodiment of the present invention, a method for transmitting downlink hybrid automatic repeat request (HARQ) information on a uplink multiple codeword transmission comprises the steps of: receiving the uplink multiple codeword transmission; generating HARQ information on each of multiple codewords, on the basis of the result of decoding each of the multiple codewords; modulating the HARQ information; and transmitting the modulated HARQ information through one or more physical HARQ indicator channels (PHICHs).

The present invention relates to a wireless communication system, and particularly, to an effective method and device for transmitting control information for supporting an uplink multi-antenna transmitting technique. According to one embodiment of the present invention, a method for transmitting control information on uplink multi-antenna transmission from a base station (BS) includes the steps of: transmitting ACK or NACK with respect to a first and a second received data blocks, respectively, by using a first PHICH resource with regard to the first data block and a second PHICH resource with regard to the second data block; receiving a retransmission with regard to a negative-acknowledged data block; and transmitting ACK or NACK for the retransmission of the negative-acknowledged data block by using the first PHICH resource reardless of which PHICH resource was used to transmit the ACK or NACK for the retransmitted data block.
