Abstract
A method in which a first device performs sidelink communication is provided according to one embodiment of the present disclosure. For example, a method in which a first device operates a first timer and/or a second timer on the basis of sidelink HARQ feedback information may be provided.
Claims14
A method for performing, sidelink communication, by a first device, the method comprising:
- transmitting, to a second device, first sidelink control information (SCI) through a first physical sidelink control channel (PSCCH);
- transmitting, to the second device, second SCI, in which a transmission resource is determined based on the first SCI, and data, through a first physical sidelink shared channel (PSSCH) related to the first PSCCH;
- receiving, from the second device, sidelink hybrid automatic repeat request (HARQ) feedback information regarding the first PSSCH;
- starting a first timer for the sidelink HARQ feedback information regarding the first PSSCH;
- and
- performing sidelink communication with the second device, based on the first timer and the sidelink HARQ feedback information,
- wherein a second PSCCH different from the first PSCCH and a second PSSCH different from the first PSSCH are not transmitted from the first device to the second device, based on the first timer running.
4 more elements
A first device for performing sidelink communication, the first device 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:
- transmit, to a second device, first sidelink control information (SCI) through a first physical sidelink control channel (PSCCH);
- transmit, to the second device, second SCI, in which a transmission resource is determined based on the first SCI, and data, through a first physical sidelink shared channel (PSSCH) related to the first PSCCH;
- receive, from the second device, sidelink hybrid automatic repeat request (HARQ) feedback information regarding the first PSSCH;
- start a first timer for the sidelink HARQ feedback information regarding the first PSSCH;
- and
- perform sidelink communication with the second device, based on the first timer and the sidelink HARQ feedback information,
- wherein a second PSCCH different from the first PSCCH and a second PSSCH different from the first PSSCH are not transmitted from the first device to the second device, based on the first timer running.
8 more elements
A device configured to control a first user equipment (UE), the device comprising:
- one or more processors;
- and
- one or more memories operably connectable to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
- transmit, to a second UE, first sidelink control information (SCI) through a first physical sidelink control channel (PSCCH);
- transmit, to the second UE, second SCI, in which a transmission resource is determined based on the first SCI, and data, through a first physical sidelink shared channel (PSSCH) related to the first PSCCH;
- receive, from the second UE, sidelink hybrid automatic repeat request (HARQ) feedback information regarding the first PSSCH;
- start a first timer for the sidelink HARQ feedback information regarding the first PSSCH;
- and
- perform sidelink communication with the second UE, based on the first timer and the sidelink HARQ feedback information,
- wherein a second PSCCH different from the first PSCCH and a second PSSCH different from the first PSSCH are not transmitted from the first UE to the second UE, based on the first timer running.
