Abstract
Provided are a vehicle-to-everything (V2X) signal transmission method performed by a terminal in a wireless communication system and an apparatus using the same. The method comprises: determining a symbol for transmitting a specific signal related to V2X communication; and transmitting the specific signal in the determined symbol, wherein the determined symbol is determined from among symbols other than symbols overlapping with a power transient period between a transmission power-on state and a transmission power-off state.
Claims14
A vehicle-to-everything (V2X) signal transmission method in a wireless communication system, the V2X signal transmission method performed by a user equipment (UE) and comprising:
- determining a symbol among candidate symbols for transmitting the V2X signal including at least one of a demodulation reference signal (DMRS), a sidelink reference signal, a primary sidelink synchronization signal (PSSS), a secondary synchronization signal (SSSS) or a signal transmitted from a physical sidelink broadcast channel (PSBCH);
- and
- transmitting the V2X signal on the determined symbol,
- wherein the candidate symbols are symbols excluding overlapping symbols which overlap a power transient period,
- wherein the power transient period is a period between a transmission power-on state and a transmission power-off state, and
- wherein, when a difference between a SSSS transmission power to which a first maximum power reduction (MPR) is applied and a PSBCH transmission power to which a second MPR is applied is smaller than a threshold value, time resources between first symbols for SSSS transmission and second symbols for PSBCH transmission are included in the candidate symbols.
A user equipment (UE) comprising:
- a radio frequency (RF) unit transmitting and receiving a radio signal;
- and
- a processor coupled to the RF unit to operate, wherein the processor:
- determines a symbol among candidate symbols for transmitting a V2X signal including at least one of a demodulation reference signal (DMRS), a sidelink reference signal, a primary sidelink synchronization signal (PSSS), a secondary synchronization signal (SSSS) or a signal transmitted from a physical sidelink broadcast channel (PSBCH), and
- transmits the V2X signal on the determined symbol,
- wherein the candidate symbols are symbols excluding overlapping symbols which overlap a power transient period,
- wherein the power transient period is a period between a transmission power-on state and a transmission power-off state, and
- wherein, when a difference between a SSSS transmission power to which a first maximum power reduction (MPR) is applied and a PSBCH transmission power to which a second MPR is applied is smaller than a threshold value, time resources between first symbols for SSSS transmission and second symbols for PSBCH transmission are included in the candidate symbols.
