Abstract
The present invention relates to a method and an apparatus which enable a terminal to transmit a signal for device-to-device (D2D) communication in a wireless communication system. Specifically, the present invention transmits a synchronization signal for D2D communication and a demodulation reference signal (DM-RS) for demodulation of the synchronization signal, wherein the base sequence of the demodulation reference signal is generated using a synchronization reference ID.
Claims18
A method by a user equipment (UE), the method comprising:
- generating a demodulation reference signal (DM-RS) related to a physical channel for UE to UE communication, based on an orthogonal code, a cyclic shift, and a sequence group number;
- and
- transmitting the physical channel and the DM-RS,
- wherein each of the orthogonal code, the cyclic shift, and the sequence group number is determined based on a synchronization identity.
A user equipment (UE) comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory storing instructions that, when executed, cause the at least one processor to perform operations comprising:
- generating a demodulation reference signal (DM-RS) related to a physical channel for UE to UE communication, based on an orthogonal code, a cyclic shift, and a sequence group number;
- and
- transmitting the physical channel and the DM-RS,
- wherein each of the orthogonal code, the cyclic shift, and the sequence group number is determined based on a synchronization identity.
A computer readable non-transitory storage medium storing instructions that, when executed, cause at least one processor to perform operations comprising:
- generating a demodulation reference signal (DM-RS) related to a physical channel for user equipment (UE) to UE communication, based on an orthogonal code, a cyclic shift, and a sequence group number;
- and
- transmitting the physical channel and the DM-RS,
- wherein each of the orthogonal code, the cyclic shift, and the sequence group number is determined based on a synchronization identity.
