Abstract: The present invention refers to a method and a transmitter element (35) for transmitting channel information (CI) for link adaptation of a radio channel (33) in a wireless network (11). In order to allow for reliable and efficient transfer of the channel information (CI) and to adapt the detection probability to the importance of the CI as well as to the channel stability, it is suggested that the method comprises encoding (19) the channel information (CI) using multi-level coding, said multi-level coding (19) comprising combining multiple bit sequences (c1, c2, . . . , cn, d), each bit sequence (c1, c2, . . . , cn, d) corresponding to a coding level (1, . . . , n) of said multilevel coding (19) and assigning (37) one of said coding levels (1, . . . , n) to at least a part (ci1, ci2) of the channel information (CI) such that at least a part (ci1, ci2) of the channel information (CI) corresponds to the bit sequence (c1, c2, . . . , cn) of that coding level (1, . . . , n).

Abstract: The present invention refers to methods and apparatus for simultaneous transmission and reception of a data sequence (d) and channel information (CI) for link adaptation. In order to provide a method, a transmitter element (34), and a receiver element (38) that consume less transmission resources and improve the overall spectral efficiency of the network, a method and a transmitter element (34) for simultaneous transmission of a data sequence (d) and channel information (CI) for link adaptation over a radio channel (29) of a wireless network (11) is suggested, the method A comprising encoding said data sequence to a codeword (c) using a channel encoder (19) and transmitting (21) the codeword (c) over the radio channel (29), wherein the method further comprises including the channel information (CI) into the codeword (c) using said channel encoder (19), the codeword (c) comprising both the data sequence (d) and the channel information (CI).
