Abstract
A method of operating a terminal in a wireless communication system is disclosed. The method of operating the terminal may comprise the terminal receiving one or more synchronization signal bocks (SSBs), selecting an SSB from among the one or more SSBs based on priority, generating at least one SSB group based on the selected SSB and a cyclic prefix (CP) boundary, and transmitting an indication message. The priority may be based on channel measurement and synchronization reference, the indication message may comprise slot configuration information based on the at least one SSB group.
Claims17
A method comprising:
- receiving, by a terminal, one or more synchronization signal blocks (SSBs);
- selecting an SSB from among the one or more SSBs based on priority;
- generating at least one SSB group based on the selected SSB and a cyclic prefix (CP) boundary, wherein each of the at least one SSB group includes a plurality of SSBs;
- transmitting an information message;
- receiving a sidelink synchronization signal (SLSS) and a physical broadcast channel (PBCH) based on the one or more SSBs;
- receiving control information based on a physical sidelink control channel (PSCCH);
- and
- receiving data based on a physical sidelink shared channel (PSSCH),
- wherein the priority is based on channel measurement and synchronization reference,
- wherein the information message comprises slot configuration information,
- wherein the slot configuration is performed for each beam based on the number of the at least one SSB group,
- wherein a 2-bit reserved period of a physical broadcast channel (PBCH) included in the one or more SSBs comprises a cast-type related parameter, and a slot is configured for each beam based on the cast-type parameter, and
- wherein the terminal determines the cast-type related parameter of a broadcast type and does not transmit the information message.
