<p>A method for distributing uplink transmission data block Acknowledge (ACK) information is disclosed in the present invention. When a terminal sends more than one transmission blocks in one uplink component carrier, the method includes that: a base station respectively feeds back the ACK information of each uplink transmission block in a downlink component carrier corresponding to the uplink component carrier through a Physical Hybrid Auto Repeat Request Indicator Channel (PHICH). A corresponding device is also disclosed in the present invention. Comparing with a method for respectively transmitting the PHICH by using multi component carriers, the present invention can save the resource of the frequency domain by using the downlink carrier group to transmit the PHICH due to that the multi component carriers are discrete frequency bands and the downlink carrier group is a large consecutive frequency band aggregated by one or more component carriers; meanwhile, the detection measurement amount for the PHICH of the User Equipment (UE) can also be reduced.</p> |
