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.
Claims8
A method of transmitting a signal by a user equipment (UE) via a communication between the UE and another UE, the method comprising:
- generating, by the UE, a plurality of bits for a physical channel including synchronization related information for the communication;
- generating, by the UE, a demodulation reference signal (DM-RS) associated with the physical channel based on an orthogonal code and a cyclic shift;
- and
- transmitting, by the UE, the physical channel and the DM-RS,
- wherein the orthogonal code for the DM-RS is determined based on a synchronization identity for the communication modulo 2, and
- wherein the cyclic shift for the DM-RS is determined based on a first value modulo 8 and the first value is a floor function of the synchronization identity divided by 2.
A user equipment (UE) for transmitting a signal in a communication between the UE and another UE, the UE comprising:
- a radio frequency (RF) unit;
- and
- a processor configured to:
- generate a plurality of bits for a physical channel including synchronization related information for the communication,
- generate a demodulation reference signal (DM-RS) associated with the physical channel based on an orthogonal code and a cyclic shift, and
- control the RF unit to transmit the physical channel and the DM-RS,
- wherein the orthogonal code for the DM-RS is determined based on a synchronization identity for the communication modulo 2, and
- wherein the cyclic shift for the DM-RS is determined based on a first value modulo 8 and the first value is a floor function of the synchronization identity divided by 2.
