Physical channels in new radio
First Claim
1. A first apparatus comprising a processor, a memory, and communication circuitry, the first apparatus being connected to a network via its communication circuitry, the first apparatus further comprising computer-executable instructions stored in the memory of the first apparatus which, when executed by the processor of the first apparatus, cause the first apparatus to perform operations comprising:
- receiving, from a second apparatus via resources that are pre-configured for the second apparatus, a grantless transmission, the grantless transmission comprising a hybrid automatic repeat request process;
receiving, from the second apparatus via a control channel, a first redundancy version of the hybrid automatic repeat request process;
sending a response to the grantless transmission, the response to the grantless transmission comprising an acknowledgement in a downlink control information, wherein the downlink control information is specific to the second apparatus, and wherein the downlink control information comprises one or more acknowledgement bits for multiple transport blocks; and
if the first apparatus does not send a positive acknowledgement of the grantless transmission, receiving, from the second apparatus and indicated via a control channel, a second redundancy version of a retransmission.

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.

4. 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:
-
sending, via resources that are pre-configured for the apparatus, a grantless transmission, the grantless transmission comprising a hybrid automatic repeat request process; indicating, through a control channel, a first redundancy version for the hybrid automatic repeat request process; receiving a response to the grantless transmission, the response to the grantless transmission, the response to the grantless transmission comprising an acknowledgement in a downlink control information, wherein the downlink control information is specific to the apparatus, and wherein the downlink control information comprises one or more acknowledgement bits for multiple transport blocks; and if a positive acknowledgement is not received; selecting a second redundancy version for a first retransmission, the first retransmission comprising the hybrid automatic repeat request process; sending, via the resources that are pre-configured for the apparatus, the first retransmission; and indicating, through the control channel, the second redundancy version for the hybrid automatic repeat request process. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
