FIELD: information technology.
SUBSTANCE: in a transmitter or transceiver, codewords from HARQ processes can be mapped or assigned to various layers for transmission and/or retransmission of information on a radio channel. Exemplary versions provide for various mappings which facilitate, for example, HARQ processes. For example, a codeword (700 OR 720) can be mapped onto a plurality of layers (702, 704 or 722, 724, 726) which are equal in number to a channel rank of a radio channel to be used for the transmission.
EFFECT: optimal codeword mapping to a layer for effective retransmission HARQ operations is provided.
