Abstract

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.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for allocating response information resources of uplink transmission data blocks. Background technique [0002] The rapid development of digital communication systems puts forward higher requirements for the reliability of data communication. However, under harsh channels, especially in high data rate or high-speed mobile environments, serious problems such as multipath interference and Doppler shift affect system performance. Therefore, an effective error control technology, especially a Hybrid Automatic Repeat Request (HARQ for short) technology has become a research hotspot in the communication field. [0003] In the HARQ mode, the code sent by the originating end can not only detect errors, but also have certain error correction capabilities. After receiving the codeword, the decoder at the receiving end first checks the error situation, and if it is ...
