Procedure and device for sending and receiving a physical downward control channel and a physical downward control joint channel in a wireless communication system

摘要

A process and device for sending and receiving a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) in a wireless communication system.The PDCCH and the PDSCH can use discrete Fourier-Transformation-sprayed orthogonal frequency multiplex (DFT-s)-OFDM) Waveform transmission.A common demodulation reference signal (DMRS) can be transmitted with the PDCCH and the PDSCH in the time multiplex process and used for demodulation of the PDCCH and the PDSCH.A phase tracking reference signal (PT-RS) can also be transmitted with the PDCCH and the PDSCHand PDCCH scan values and PDSCH scan values can be multiplied in the time range before DFT processing, so that PDCCH and PDSCH are multiplied in the same DFT-s OFDM symbol.Alternatively, a PDCCH can also be transmitted via two or more antenna connections.
