Abstract: A scheduling node (110) transmits, to a radio node (105) configured for sub-subframe operation, a semi-persistent scheduling (SPS) configuration message (210) configuring the radio node (105) for sub-subframe-based SPS. The SPS configuration message (210) comprises an identifier of the radio node (105) and indicates a pattern of sub-subframes (82) in which a resource allocation for the radio node (105) repeats. The radio node (105) receives the SPS configuration message (210) and configures the radio node (105) for sub-subframe-based SPS according to the SPS configuration message (210).

Abstract: According to certain embodiments, a method is disclosed for use in a wireless device. The method comprises transmitting uplink data to a network node. The uplink data is transmitted according to a semi-persistent scheduling (SPS) configuration obtained from the network node. The uplink data is transmitted without transmitting padding when no data is available for transmission. The method further comprises retransmitting the uplink data to the network node until receiving an indication to transmit new uplink data. The indication is received from the network node via a control channel.

Abstract: A network node, a wireless device for communication with a network node and corresponding methods are provided. The network node includes processing circuitry configured to stop a hybrid automatic repeat request (HARQ) process associated with data to be retransmitted and retransmit the data using a procedure that is different from the stopped HARQ process.
