METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING REFERENCE SIGNAL IN DEVICE-TO-DEVICE COMMUNICATION |
摘要 |
A method and an apparatus for generating a sequence including a demodulation reference signal (DM RS) and a preamble in device-to-device (D2D) communications are provided. The method includes obtaining, by a controller of an apparatus, a synchronization identify of a synchronization signal used for the D2D communication, obtaining a group identify of a communication group where a terminal belongs, generating a DM RS sequence for the D2D communication based on at least one of the synchronization identity and the group identity, mapping the DM RS sequence to predetermined symbol positions in a subframe, and transmitting the DM RS sequence from the terminal through the subframe. |
