FIELD: radio engineering, communication.SUBSTANCE: wireless communication method includes: receiving downlink signalling on a plurality of downlink carriers; determining hybrid automatic repeat request (HARQ) feedback corresponding to each of the plurality of carriers; selecting a first HARQ feedback symbol for encoding HARQ feedback corresponding to a first subset of the plurality of carriers comprising at least two of the plurality of carriers; the first HARQ feedback symbol is selected from one of a plurality of code books which store symbols corresponding to a composite value representing the decoding status of information received on at least two of the plurality of carriers; selecting a second HARQ feedback symbol for encoding HARQ feedback corresponding to a second subset of the plurality of carriers comprising at least one of the plurality of carriers; wherein the second HARQ feedback symbol is selected from one of the plurality of code books which store symbols corresponding to a composite value representing the decoding status of information received on at least one of the plurality of carriers; and transmitting the first and second HARQ feedback symbols on an uplink.EFFECT: providing feedback in a multi-carrier communication system.14 cl, 9 dwg |
