Method and apparatus for transmission and reception of broadcast information in wireless communication system

A method performed by a second terminal in a wireless communication system, the method comprising:

• receiving, from a first terminal on a physical sidelink broadcast channel (PSBCH), slot format information for a sidelink communication, the slot format information including first information on a number of one or more patterns, second information on a period of the one or more patterns, and third information on a number of uplink slots of the one or more patterns;
• and
• performing, with the first terminal, the sidelink communication in at least one sidelink resource identified based on the first information, the second information, and the third information,
• wherein, in case that the first information indicates the number of the one or more patterns as 1, the second information indicates the period of the one or more patterns for a first pattern, and the third information indicates the number of uplink slots for the first pattern, a value of the third information is associated with a number of uplink slots of the first pattern and at least one of a subcarrier spacing parameter, and
• wherein, in case that the first information indicates the number of the one or more patterns as 2, the second information indicates the period of the one or more patterns for the first pattern and a second pattern, and the third information indicates the number of uplink slots for the first pattern and the second pattern, a value of the third information is associated with the number of uplink slots of the first pattern, a number of uplink slots of the second pattern, a number of total slots of the first pattern, and the at least one of the subcarrier spacing parameter.

A first terminal in a wireless communication system, the first terminal comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a controller configured to:
• transmit, to a second terminal on a physical sidelink broadcast channel (PSBCH), slot format information for a sidelink communication, the slot format information including first information on a number of one or more patterns, second information on a period of the one or more patterns, and third information on a number of uplink slots of the one or more patterns, and
• perform, with the second terminal, the sidelink communication in at least one sidelink resource identified based on the first information, the second information, and the third information,
• wherein, in case that the first information indicates the number of the one or more patterns as 1, the second information indicates the period of the one or more patterns for a first pattern, and the third information indicates the number of uplink slots for the first pattern, a value of the third information is associated with a number of uplink slots of the first pattern and at least one of a subcarrier spacing parameter, and
• wherein, in case that the first information indicates the number of the one or more patterns as 2, the second information indicates the period of the one or more patterns for the first pattern and a second pattern, and the third information indicates the number of uplink slots for the first pattern and the second pattern, a value of the third information is associated with the number of uplink slots of the first pattern, a number of uplink slots of the second pattern, a number of total slots of the first pattern, and the at least one of the subcarrier spacing parameter.

A second terminal in a wireless communication system, the second terminal comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a controller configured to:
• receive, from a first terminal on a physical sidelink broadcast channel (PSBCH), slot format information for a sidelink communication, the slot format information including first information on a number of one or more patterns, second information on a period of the one or more patterns, and third information on a number of uplink slots of the one or more patterns, and
• perform, with the first terminal, the sidelink communication in at least one sidelink resource identified based on the first information, the second information, and the third information,
• wherein, in case that the first information indicates the number of the one or more patterns as 1, the second information indicates the period of the one or more patterns for a first pattern, and the third information indicates the number of uplink slots for the first pattern, a value of the third information is associated with a number of uplink slots of the first pattern and at least one of a subcarrier spacing parameter, and
• wherein, in case that the first information indicates the number of the one or more patterns as 2, the second information indicates the period of the one or more patterns for the first pattern and a second pattern, and the third information indicates the number of uplink slots for the first pattern and the second pattern, a value of the third information is associated with the number of uplink slots of the first pattern, a number of uplink slots of the second pattern, a number of total slots of the first pattern, and the at least one of the subcarrier spacing parameter.
