Abstract: Hybrid automatic repeat request (HARQ) processes may be transmitted via configured grants as well as scheduled grants. The configured grants may include time and frequency resources, and transmissions may occur across contiguous transmissions. HARQ process information, such as HARQ IDs and redundancy versions, may be communicated via a control channel, and the control channel may be multiplexed with the transmission resources of the configured grants. Retransmission timers may be used for HARQ processes conveyed via configured grants, and the transmitting apparatus may signal to a receiver when to send an acknowledgement. An acknowledgement may take the form of bitmaps for code block groups of a HARQ. A configured grant may be selected from among multiple configured grants based upon low latency, for example. A group of configured grants may be activated or deactivated via a single command.
