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.
Claims17
A method of transmitting a signal by a user equipment (UE) via a communication between the UE and another UE, the method comprising:
- generating a plurality of bits for a physical channel;
- generating a demodulation reference signal (DM-RS) related to the physical channel, based on an orthogonal code, a cyclic shift, and a sequence;
- and
- transmitting the physical channel and the DM-RS,
- wherein each of the orthogonal code, the cyclic shift, and the sequence is determined based on a synchronization identity.
A user equipment (UE) in a communication between the UE and another UE, the 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 plurality of bits for a physical channel;
- generating a demodulation reference signal (DM-RS) related to the physical channel, based on an orthogonal code, a cyclic shift, and a sequence;
- and
- transmitting the physical channel and the DM-RS,
- wherein each of the orthogonal code, the cyclic shift, and the sequence is determined based on a synchronization identity.
A method of receiving a signal by a user equipment (UE) via a communication between the UE and another UE, the method comprising:
- receiving a physical channel and a demodulation reference signal (DM-RS) related to the physical channel;
- and
- obtaining a plurality of bits based on the physical channel;
- wherein the DM-RS is determined based on an orthogonal code, a cyclic shift, and a sequence;
- and
- wherein each of the orthogonal code, the cyclic shift, and the sequence is determined based on a synchronization identity.
