FIELD: radio communications; data transfer in radio system; retransmission of data transferred with errors. ^ SUBSTANCE: physical-level data stream meant for transmission has plurality of subblocks; each subblock has error correction code, service quality, and priority; if subblocks have different service qualities, physical-level coded data stream is divided into plurality of slots. Slot data are transferred to receiver in desired time intervals. If hybrid automatic repetition message determining reception error in at least one of subblocks in source slot data and no-error reception of other subblocks is received from source slot data receiver, then slot data incorporating error repeated within range of subblocks are retransmitted upon transmission of source slot data. ^ EFFECT: enhanced precision of data transfer. ^ 6 cl, 9 dwg |
