METHOD AND DEVICE FOR SENDING AND RECEIVING DEMODULATION REFERENCE SIGNAL ON NEW CARRIER TYPE (NCT) CARRIER

摘要

The present invention relates to a NCT in which there is no control region comprising a PDCCH. And, a method according to one embodiment of the present invention, wherein a base station sends a demodulation reference signal having orthogonality on a carrier which is NCT, comprises: a step wherein code-division multiplexing is carried out by using orthogonal code with respect to the demodulation reference signal which maps onto a symbol that overlaps PSS and SSS disposed in a carrier downlink subframe; and a step of sending a downlink comprising the demodulation reference signal in which the code-division multiplexing has been used.

1. A method of transmitting a demodulation reference signal having orthogonality in a new carrier type (NCT) carrier, performed by a base station, the method comprising:
performing code division multiplexing on a demodulation reference signal to be mapped onto a symbol overlapped with a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS) positioned in a downlink subframe of the carrier by using an orthogonal code; and transmitting the demodulation signal to which the code division multiplexing is applied through downlink.
