Abstract

Proposed is an operation method of a first device in a wireless communication system. The method may comprise the steps of: receiving, from a base station, TDD-UL-DL configuration information including information related to a first slot pattern and information related to a second slot pattern; acquiring the number of first SL slots related to the first slot pattern and the number of second SL slots related to the second slot pattern on the basis of first SCS related to SL communication and the TDD-UL-DL configuration information; and transmitting, to a second device, a PSBCH including information related to the number of the first SL slots and information related to the number of the second SL slots.

Claims15

Dependent claims

A method for a first apparatus to perform wireless communication, the method comprising:

receiving time division duplex-uplink-downlink (TDD-UL-DL) configuration information including information related to a first slot pattern and information related to a second slot pattern from a base station,
wherein the information related to the first slot pattern includes information related to a period of the first slot pattern and information related to a first UL resource, and
wherein the information related to the second slot pattern includes information related to a period of the second slot pattern and information related to a second UL resource;
obtaining the number of first sidelink (SL) slots related to the first slot pattern and the number of second SL slots related to the second slot pattern, based on a first subcarrier spacing (SCS) related to SL communication and the TDD-UL-DL configuration information;
and
transmitting a physical sidelink broadcast channel (PSBCH) including information related to the number of the first SL slots and information related to the number of the second SL slots to a second apparatus,
wherein the number of the first SL slots and the number of the second SL slots are expressed based on a unit counting a plurality of slots as one, based on i) the information related to the period of the first slot pattern, ii) the information related to the period of the second slot pattern, and iii) the first SCS, and
wherein the SL communication is performed based on the number of the first SL slots and the number of the second SL slots.
