Abstract
One embodiment of the present invention is a method by which a D2D terminal transmits a synchronization signal in a wireless communication system, the synchronization signal transmission method comprising: generating a primary sidelink synchronization signal (PSSS); and transmitting the PSSS, wherein the transmission power of the PSSS is the same as the transmission power of a channel in which system and synchronization-related information is transmitted.
Claims14
A method for transmitting a synchronization signal by a user equipment (UE) in a wireless communication system supporting a sidelink, the method comprising:
- generating a primary sidelink synchronization signal (PSSS) and a secondary sidelink synchronization signal (SSSS);
- and
- transmitting, to another UE, the PSSS in first Orthogonal Frequency Division Multiplexing (OFDM) symbols, a Physical Sidelink Broadcast Channel (PSBCH) in second OFDM symbols, and the SSSS in third OFDM symbols,
- wherein the first OFDM symbols, the second OFDM symbols and the third OFDM symbols are included in a subframe,
- wherein a transmission power allocated to the PSSS per OFDM symbol in the first OFDM symbols is equal to a transmission power allocated to the PSBCH per OFDM symbol in the second OFDM symbols, and
- wherein a transmission power allocated to the SSSS per OFDM symbol in third OFDM symbols is different from the transmission power allocated to the PSBCH per OFDM symbol in the second OFDM symbols.
A User Equipment (UE) in a wireless communication system supporting a sidelink, the UE comprising:
- a transmission module and a reception module;
- and
- a processor,
- wherein the processor:
- generates a primary sidelink synchronization signal (PSSS), and a secondary sidelink synchronization signal (SSSS),
- transmits, to another UE, the PSSS in first Orthogonal Frequency Division Multiplexing (OFDM) symbols, a Physical Sidelink Broadcast Channel (PSBCH) in second OFDM symbols, and the SSSS in third OFDM symbols,
- wherein the first OFDM symbols, the second OFDM symbols and the third OFDM symbols are included in a subframe,
- wherein a transmission power allocated to the PSSS per OFDM symbol in the first OFDM symbols is equal to a transmission power allocated to the PSBCH per OFDM symbol in the second OFDM symbols, and
- wherein a transmission power allocated to the SSSS per OFDM symbol in third OFDM symbols is different from the transmission power allocated to the PSBCH per OFDM symbol in the second OFDM symbols.
