Method, carried out by terminal, for transmitting PSBCH in wireless communication system and terminal utilizing the method
Provided are a method, carried out by a terminal, for transmitting a physical sidelink broadcast channel (PSBCH) and a terminal utilizing the method. The method determines whether the terminal is in or out of cell coverage, and whether a discovery signal to be transmitted by the terminal is a public safety (PS) discovery signal for PS. If the terminal is outside the cell coverage and is to transmit a PS discovery signal, then when a sidelink synchronization signal (SLSS) is transmitted in a discovery period, a PSBCH is also transmitted therewith.
1. A method for transmitting a physical sidelink broadcast channel (PSBCH) in a wireless communication system, the method performed by a terminal and comprising:
generating a sidelink synchronization signal (SLSS); and
transmitting the SLSS in a subframe,
wherein when the terminal is outside a cell coverage and is to transmit a public safety (PS) discovery signal, the terminal transmits the PSBCH in the subframe.
2. The method of claim 1 , wherein the PS discovery signal includes a type 1 discovery signal transmitted by using a resource selected by the terminal itself in a resource pool configured by the network.
3. The method of claim 1 , wherein the PSBCH is a channel for carrying system information and information on synchronization.
4. The method of claim 1 , wherein the SLSS and PSBCH are transmitted every 40 milliseconds (ms) within a discovery period.
5. A terminal, comprising:
a transceiver configured to transmit and receive a radio signal; and
a processor configured to operatively coupled to the transceiver,
wherein the processor generates a sidelink synchronization signal (SLSS), and transmits the SLSS in a subframe, when
the terminal is outside a cell coverage and is to transmit a public safety (PS) discovery signal, the terminal transmits the PSBCH in the subframe.
6. The terminal of claim 5 , wherein the PS discovery signal includes a type 1 discovery signal transmitted by using a resource selected by the terminal itself in a resource pool configured by the network.
7. The terminal of claim 5 , wherein the PSBCH is a channel for carrying system information and information on synchronization.
8. The terminal of claim 5 , wherein the SLSS and PSBCH are transmitted every 40 milliseconds (ms) within a discovery period.
