Embodiment Construction

[0019] As understood by those skilled in the art, aspects of the embodiments may be embodied as systems, devices, methods or program products. Accordingly, an embodiment may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, microcode, etc.) or an embodiment combining software and hardware aspects.

[0020] For example, the disclosed embodiments may be implemented as hardware circuits comprising custom very large scale integration ("VLSI") circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. The disclosed embodiments may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices, and the like. As another example, the disclosed embodiments may comprise one or more physical or logical blocks of executable code which, for example, may be organized as objects, p...

Abstract

Apparatuses, methods, and systems are disclosed for autonomous packet duplication and retransmission. One apparatus (600) includes a processor (605) that generates (805) a first PDU for a first uplink grant associated with a first HARQ process and generates (810) a second MAC PDU for a second uplink grant associated with a second HARQ process. Here, the first uplink grant is a configured grant, the second uplink grant has overlapping PUSCH resources with the first uplink grant, and the second uplink grant has a higher priority than the first uplink grant. The apparatus (600) includes a transceiver (625) that transmits (815) the second MAC PDU according to the second uplink grant and does not transmit the first MAC PDU according to the first uplink grant. The processor (605) autonomously triggers (820) a retransmission of the first MAC PDU for the first HARQ process without receiving network signaling for the retransmission.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent No. 62 / 809,483, filed January 22, 2019, by Joachim Loehr, Ravi Kuchibhotla, and Karthikeyan Ganesan, entitled "SELECTIVE DUPLICATION FOR HIGH URGENCY DATA" , which application is incorporated herein by reference. technical field [0003] The subject matter disclosed herein relates generally to wireless communications, and more specifically to selective replication for high-urgency ultra-reliable data transmission. Background technique [0004] The following abbreviations are defined here, some of which are referenced in the description below: [0005] Third Generation Partnership Project (“3GPP”), Fifth Generation Core Network (“5CG”), Fifth Generation System (“5GS”), Authentication, Authorization and Accounting (“AAA”), Access and Mobility Management Function (“AMF”), Acknowledgment (“ACK”), Application Programming Interface (“API”), Access Stratum (“AS”), ...
