Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A host computer, comprising:
processing circuitry configured to provide user data; and
a network interface configured to initiate transmission of the user data from a network node in a cellular network to a user equipment (UE), the network node having a communication interface and processing circuitry, the processing circuitry of the network node configured to perform operations comprising:
receiving, from the UE, a semi-persistent scheduled, SPS, uplink, UL, data transmission associated with a hybrid automatic repeat request, HARQ, process, a SPS transmission being a transmission performed without a dynamic grant and the HARQ process being one of a plurality of HARQ processes;
measuring a time, T, subsequent to receipt of the SPS UL data transmission;
attempting a decoding of the SPS UL data transmission and not sending, to the UE, an ACK for the received SPS UL data transmission when the attempted decoding is successful; and
receiving, after time T has elapsed, for a HARQ process identification, ID, one of a new SPS UL data transmission and a retransmission of the previously received SPS UL data transmission with a HARQ process ID selected based on a relationship between time T and a time, τ, during which the UE cycles through the plurality of HARQ, processes.
