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.
Claims16
A method for performing long-term evolution (LTE) sidelink (SL) communication through downlink control information (DCI) by a first apparatus, the method including:
- receiving downlink control information (DCI) through a physical downlink control channel (PDCCH) from anew radio (NR) base station;
- obtaining a first timing offset and a second timing offset related to LTE SL communication based on the DCI;
- and
- performing the LTE SL communication from an initial LTE SL communication time determined based on the first timing offset and the second timing offset,
- wherein a time after a lapse of the first timing offset from a time when the first apparatus receives the DCI from the NR base station is equal to a time when it is determined that the first apparatus has received LTE dedicated DCI from an LTE base station with respect to the LTE SL communication.
A first apparatus for performing LTE SL communication through DCI, the first apparatus comprising:
- at least one memory to store instructions;
- at least one transceiver;
- and
- at least one processor to connect the at least one memory and the at least one transceiver,
- wherein the at least one processor is configured to:
- control the at least one transceiver to receive downlink control information (DCI) through a physical downlink control channel (PDCCH) from a new radio (NR) base station,
- obtain a first timing offset and a second timing offset related to LTE SL communication based on the DCI, and
- perform the LTE SL communication from an initial LTE SL communication time determined based on the first timing offset and the second timing offset,
- wherein a time after a lapse of the first timing offset from a time when the first apparatus receives the DCI from the NR base station is equal to a time when it is determined that the first apparatus has received LTE dedicated DCI from an LTE base station with respect to the LTE SL communication.
An apparatus for controlling a first terminal, the apparatus comprising:
- at least one processor;
- and
- at least one computer memory that is connected to be executable by the at least one processor and stores instructions,
- wherein, when the at least one processor executes the instructions, the first terminal is configured to:
- receive downlink control information (DCI) through a physical downlink control channel (PDCCH) from anew radio (NR) base station,
- obtain a first timing offset and a second timing offset related to LTE SL communication based on the DCI, and
- perform the LTE SL communication from an initial LTE SL communication time determined based on the first timing offset and the second timing offset,
- wherein a time after a lapse of the first timing offset from a time when the first apparatus receives the DCI from the NR base station is equal to a time when it is determined that the first apparatus has received LTE dedicated DCI from an LTE base station with respect to the LTE SL communication.
