Abstract
Provided herein are a method for performing wireless communication by a first apparatus and an apparatus for supporting the same. The method may include the steps of receiving a service from a second apparatus, through a data link including multiple data paths, and determining whether or not to transmit a sidelink hybrid automatic repeat request (SL HARQ) feedback being related to the service to the second apparatus. Herein, based on Quality of Service (QoS) requirements of a service being transmitted through the multiple data paths, the data link may include the multiple data paths.
Claims18
A method for transmitting, by a first apparatus, hybrid automatic repeat request (HARQ) feedback, the method comprising:
- receiving, from a second apparatus, sidelink control information (SCI) including information that enables the HARQ feedback related to a first Medium Access Control Protocol Data Unit (MAC PDU);
- receiving, from the second apparatus, the first MAC PDU including data related to enabling of the HARQ feedback;
- and
- transmitting, to the second apparatus, the HARQ feedback in response to the first MAC PDU,
- wherein the first MAC PDU includes no data related to disabling of the HARQ feedback.
A first apparatus for transmitting hybrid automatic repeat request (HARQ) feedback, the first apparatus comprising:
- one or more memories storing instructions;
- one or more transceivers;
- and
- one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
- receive, from a second apparatus, sidelink control information (SCI) including information that enables the HARQ feedback related to a first Medium Access Control Protocol Data Unit (MAC PDU);
- receive, from the second apparatus, the first MAC PDU including data related to enabling of the HARQ feedback;
- and
- transmit, to the second apparatus, the HARQ feedback in response to the first MAC PDU,
- wherein the first MAC PDU includes no data related to disabling of the HARQ feedback.
An apparatus configured to control a first user equipment (UE), the apparatus comprising:
- one or more processors;
- and
- one or more memories being operably connectable to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
- receive, from a second UE, sidelink control information (SCI) including information that enables the HARQ feedback related to a first Medium Access Control Protocol Data Unit (MAC PDU);
- receive, from the second UE, the first MAC PDU including data related to enabling of the HARQ feedback;
- and
- transmit, to the second UE, the HARQ feedback in response to the first MAC PDU,
- wherein the first MAC PDU includes no data related to disabling of the HARQ feedback.
