A device and a method for automatically restoring a seatback is provided in which a seatback is electrically deployed at a predetermined angle by being interlocked when a seat of a vehicle is moved to a predetermined position to facilitate a passenger to get into and out of the vehicle. The device includes a seat cushion, a seatback installed in the seat cushion to be adjustable in angle, a seat rail, and a seat track slidably installed in the seat rail. A seat position detection sensor detects a position of the seat track and a seat position detection member operates the seat position detection sensor. A seatback angle adjustment motor adjusts an angle of the seatback. When the seat position detection sensor detects that the seat track reaches a predetermined operating position, the seatback angle adjustment motor deploys the seatback.

A technique for receiving and transmitting downlink reference signals is disclosed. When transmitting downlink data demodulation reference signals (DMRS) (or reference signals for downlink data demodulation) by using two or more layers, the DMRS of each layer may be multiplexed by using a code division multiplexing method and then transmitted. The DMRS for each of the two or more layers may be used for one user equipment or for two or more user equipments. And, downlink control signals for transmitting and receiving such DMRS may be configured to have the same format regardless of a single-user mode (or SU-MIMO mode) or a multi-user mode (or MU-MIMO mode), thereby being used.
