Abstract:
A technique for encoding downlink Hybrid Automatic Repeat Request, HARQ, feedback information in a mobile station supporting aggregated component carriers is provided. A method implementation of this technique comprises the steps of obtaining (302) first HARQ feed-back indicators providing information regarding receipt of Physical Downlink Control Channels, PDCCH, for activated component carriers, obtaining (304) second HARQ feedback indicators providing information regarding decoding of Physical Downlink Shared Channels, PDSCH, codewords carried by the component carriers, encoding (306) the first HARQ feedback indicators into a first coded part, and encoding (308) the first HARQ feedback indicators into a second coded part, wherein the first and the second HARQ feedback indicators are encoded separate from each other.
