Abstract
One embodiment of the present disclosure provides a method for a first device carrying out Long-Term Evolution (LTE) sidelink (SL) communication via downlink control information (DCI). The method comprises the steps of: receiving DCI from a NR base station via a physical downlink control channel (PDCCH); on the basis of the DCI, acquiring a first timing offset, and a second timing offset which is associated with LTE SL communication; and carrying out LTE SL communication from the time point of the very first LTE SL communication determined on the basis of the first timing offset and the second timing offset.

A method for performing sidelink (SL) transmission by a first device, the method comprising:
- receiving, from a base station, control information including information regarding a first timing offset related to a minimum latency and information regarding a second timing offset related to activation of a SL semi persistent scheduling (SPS) configuration;
- and
- performing long-term evolution (LTE) SL transmission based on the control information,
- wherein a start time of the LTE SL transmission is based on (i) the first timing offset, (ii) the second timing offset, (iii) a timing advance between downlink and uplink, and (iv) a time when the first device detects the control information.
A first device adapted to perform sidelink (SL) transmission, the first device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the at least one processor to perform operations comprising:
- receiving, from a base station, control information including information regarding a first timing offset related to a minimum latency and information regarding a second timing offset related to activation of a SL semi persistent scheduling (SPS) configuration;
- and
- performing long-term evolution (LTE) SL transmission based on the control information,
- wherein a start time of the LTE SL transmission is based on (i) the first timing offset, (ii) the second timing offset, (iii) a timing advance between downlink and uplink, and (iv) a time when the first device detects the control information.
A processing device adapted to control a first device performing sidelink (SL) transmission, the processing device comprising:
- at least one processor;
- and
- at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the at least one processor to perform operations comprising:
- receiving, from a base station, control information including information regarding a first timing offset related to a minimum latency and information regarding a second timing offset related to activation of a SL semi persistent scheduling (SPS) configuration;
- and
- performing long-term evolution (LTE) SL transmission based on the control information,
- wherein a start time of the LTE SL transmission is based on (i) the first timing offset, (ii) the second timing offset, (iii) a timing advance between downlink and uplink, and (iv) a time when the first device detects the control information.
