Title: Uplink channel demodulation method and uplink channel demodulation apparatus
Inventor: YU YAWEI
IPC: H04L5/00
Filed: 2020-01-10
Abstract: The present application provides an uplink channel demodulation method and an uplink channel demodulation apparatus. The method comprises: receiving a sounding reference signal (SRS) sent by a terminal device; receiving an uplink channel sent by the terminal device; and using the SRS to perform channel estimation on the uplink channel and demodulate information carried on the uplink channel. Since the SRS is not carried on the uplink channel, in other words, the SRS and the uplink channel are sent independently, using the SRS to estimate the uplink channel and demodulate the information carried on the uplink channel can reduce the sending of or even eliminate the need to send a demodulation reference signal (DMRS) on the uplink channel. Therefore, the overhead of the DMRS in the uplink channel can be reduced while ensuring the demodulation performance of the data of the uplink channel.
