1. A method in a wireless device, comprising:
transmitting uplink data to a network node, the uplink data transmitted according to a semi-persistent scheduling (SPS) configuration obtained from the network node wherein the SPS configuration specifies a number of hybrid automatic repeat request (HARQ) processes, the number greater than 1, wherein uplink data is transmitted via at least a first HARQ process without transmitting padding during at least a second HARQ process in which no data is available for transmission; and
retransmitting the uplink data to the network node until receiving an indication to transmit new uplink data, the indication received from the network node via a control channel.
