Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation of the present disclosure will be further described in detail with reference to the accompanying drawings.

[0022] The "module" mentioned here generally refers to a program or an instruction stored in a memory capable of performing certain functions. The "unit" mentioned here generally refers to a logically divided functional structure. A "unit" may be realized by pure hardware or a combination of hardware and software.

[0023] The "plurality" mentioned here refers to two or more than two. The term "and / or" is used to describe the association of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist together, and B exists alone. The character " / " usually indicates that the context object is an "or" relationship. Words "first", "second" and similar terms used in the descr...

Abstract

A method and user equipment (UE) for retransmission are provided. In the method, the UE receives an uplink (UL) grant for retransmission from a gNodeB (gNB), and the UE determines whether to ignore the UL grant.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular, to a method and user equipment (UE) for retransmission. Background technique [0002] At the RAN2#107bis Chongqing meeting, it was agreed on the following: [0003] Chairman's summary: [0004] - Everyone agrees (according to the previous agreement) that gNB-scheduled retransmissions of deprioritized transmissions should be supported. [0005] - Allowing "UE automatic retransmission in uplink grant (CG) resources" is strongly supported. For this case, the MAC (Multiple Access Channel) will not regenerate the PDU (Packet Data Unit), but whether the transmission is considered a HARQ (Hybrid Automatic Repeat Request) new transmission or a HARQ retransmission is pending. [0006] There is no consensus on making additional efforts to speed up retransmissions by using another HARQ process if needed. [0007] - It seems unclear whether New Radio (NR-U) solutions in unlicensed sp...
