Physical Channels In New Radio
First Claim
1. An apparatus comprising a processor, a memory, and communication circuitry, the apparatus being connected to a network via its communication circuitry, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to perform operations comprising:
- transmitting a first transport block comprising a first set of groups of code blocks;
receiving a multibit ACK-NACK response for the first transport block, the multibit ACK-NACK response for the first transport block comprising an ACK-NACK response for each group of code blocks in the first transport block; and
transmitting a second transport block comprising a second set of groups of code blocks, the second set of groups of code blocks comprising only those groups of code blocks of the first set of code blocks for which no ACK response was received in the multibit ACK-NACK response.

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.
