Abstract
One embodiment of the present disclosure provides a method by which a first apparatus transmits a sidelink-synchronization signal block (SL-SSB). The method is characterized in comprising the steps of: determining a first resource considered that a first SL-SSB is transmittable; and transmitting the first SL-SSB to a second apparatus based on the first resource. Accordingly, apparatuses based on V2X communication in wireless communication system may efficiently relay or transmit and receive SL-SSB based on a slot format.
Claims12
A method for transmitting a sidelink-synchronization signal block (SL-SSB) by a first apparatus, the method including:
- generating the SL-SSB including a sidelink primary synchronization signal (SPSS), a sidelink secondary synchronization signal (SSSS) and a sidelink physical broadcast channel (PSBCH);
- determining a first resource capable of transmitting a first SL-SSB;
- determining a second resource based on a slot format of the first SL-SSB among the first resource;
- and
- transmitting the first SL-SSB to a second apparatus based on the second resource,
- wherein the first resource is determined based on a starting symbol index and an ending symbol index in a slot for the first SL-SSB, and
- wherein the second resource represents a resource that overlaps with an uplink (UL) resource or a sidelink (SL) resource based on the slot format among the first resource.
A first apparatus transmitting a sidelink-synchronization signal block (SL-SSB), the first apparatus including:
- at least one memory storing instructions;
- at least one transceiver;
- and
- at least one processor connecting the at least one memory and the at least one transceiver,
- wherein the at least one processor is configured to:
- generate the SL-SSB including a sidelink primary synchronization signal (SPSS), a sidelink secondary synchronization signal (SSSS) and a sidelink physical broadcast channel (PSBCH);
- determine a first resource capable of transmitting a first SL-SSB;
- determine a second resource based on a slot format of the first SL-SSB among the first resource;
- and
- control the at least one transceiver to transmit the first SL-SSB to a second apparatus based on the second resource,
- wherein the first resource is determined based on a starting symbol index and an ending symbol index in a slot for the first SL-SSB, and
- wherein the second resource represents a resource that overlaps with an uplink (UL) resource or a sidelink (SL) resource based on the slot format among the first resource.
An apparatus controlling a first terminal, the apparatus including:
- at least one processor;
- and
- at least one computer memory operably coupled by the at least one processor and storing instructions,
- wherein, by the at least one processor executing the instructions, the first terminal is configured to:
- generate the SL-SSB including a sidelink primary synchronization signal (SPSS), a sidelink secondary synchronization signal (SSSS) and a sidelink physical broadcast channel (PSBCH);
- determine a first resource capable of transmitting a first SL-SSB;
- determine a second resource based on a slot format of the first SL-SSB among the first resource;
- and
- transmit the first SL-SSB to a second apparatus based on the second resource,
- wherein the first resource is determined based on a starting symbol index and an ending symbol index in a slot for the first SL-SSB, and
- wherein the second resource represents a resource that overlaps with an uplink (UL) resource or a sidelink (SL) resource based on the slot format among the first resource.
