Title: PILOT FREQUENCY MAPPING METHOD AND DEVICE
Abstract:
Disclosed are a pilot frequency mapping method and device, for distributing an independent DMRS for a control channel and a data channel of a control region, thereby realizing the demodulation of the control channel and the data channel of the control region based on the DMRS. The method comprises: determining a control channel and a first data channel to be demodulated, wherein both a resource unit for transmitting the control channel and a resource unit for transmitting the first data channel belong to a control region of short transmission time interval, and respectively mapping a demodulation reference signal (DMRS) for the control channel and the first data channel in the control region, wherein the DMRS of the control channel is a first DMRS, the DMRS of the first data channel is a second DMRS, and the first DMRS and the second DMRS are independent from each other.
