摘要
FIELD: wireless communication equipment.;SUBSTANCE: invention relates to wireless communication and more specifically to methods for improving efficiency of feedback of hybrid automatic retransmission request. Technical result of the disclosed technical solution is achieved by the fact that in the disclosed solution it is provided for possibility to receive through the physical downlink control channel (PDCCH) downlink control information (DCI). DCI may include a field which indicates retransmission based on a code blocks group (CBG) for at least one transport block (TB). Provided that DCI does not include said field, WTRU may transmit, via physical uplink control channel (PUCCH), one-bit HARQ feedback for TB-based retransmission. Provided that DCI includes said field, WTRU can transmit by PUCCH multi-bit HARQ feedback for CBG based retransmission.;EFFECT: technical result is wider range of means for creating more flexible circuits for repeated transmission of data.;18 cl, 16 dwg, 1 tbl
