Abstract

A method, wireless device and network node are disclosed. According to one aspect, a wireless device comprises a radio interface configured to obtain a timer value, T, for measuring time elapsed from a start of a semi-persistent scheduled, SPS, uplink, UL, data transmission. The wireless device comprises processing circuitry configured to perform an SPS UL data transmission associated with a hybrid automatic repeat request, HARQ, process identification, ID, wherein the HARQ process ID is one of a plurality of HARQ process IDs. The processing circuitry is configured to perform a new data transmission or autonomous retransmission with said HARQ process ID at the next available time for said HARQ process ID after elapsed time T.
