Abstract
Hybrid automatic repeat request (HARQ) processes, indicators, and similar methods may be used improve new radio performance in a number of ways. For example HARQ processes may be retransmitted, even before a response is expected, a number of times. Separate acknowledgement may be provided for various code blocks within a single transport block. Multi-bit ACK/NACK signaling may be used to efficiently express the status of individual code blocks or groups of code blocks within a transmission block. Grantless transmissions may be acknowledged implicitly, e.g., via responses comprising downlink control information or sent via a physical hybrid automatic repeat request indicator channel.
