Abstract

A direct radio transmission communications system comprises a first transceiver and at least one second transceiver. The first transceiver is configured to transmit a data packet (20) comprising at least one data packet fragment (21₁, 21₂, 21₃, 21₄, 21₅). The at least one second transceiver is adapted to attempt to receive all the data packet fragments (21₁, 21₂, 21₃, 21₄, 21₅) of the data packet (20). The at least one second transceiver is configured to, if at least one data packet fragment (21₁, 21₂, 21₃, 21₄, 21₅) of the data packet (20) has not been received successfully by the at least one second transceiver, transmit a Not-Acknowledge, NACK, signal to the first transceiver. The NACK signal therein comprises a NACK sub-signal for each not successfully received data packet fragment (21₁, 21₂, 21₃, 21₄, 21₅) of the data packet (20), each within a specific NACK signal sub-timeslot (25₁, 25₂, 25₃, 25₄, 25₅, 25₆, 25₇, 25₈, 25₉, 25₁₀) dedicated to a specific sequential data packet fragment number of the not successfully received data packet fragment (21₁, 21₂, 21₃, 21₄, 21₅) of the data packet (20) .
