Which channels in 5G can use beamforming technique?

Digital beamforming (MU-MIMO) is used in LTE Advanced Pro (transmission modes 7,8, and 9) and in 5G NR. Digital beamforming improves the cell capacity as the same PRBs (frequency/time resources) can be used to transmit data simultaneously for multiple users.

What are the types of beamforming?

Depending on who you ask, you'll be told there are two types of beamforming. These are either analog or digital, or switched and adaptive beamforming.

What is SRS based beamforming?

The sounding reference signal (SRS) based downlink beamforming using uplink channel estimation gets the correlation coefficient between SRSs received from each receiver of a base station and obtains the maximum beamforming gain by tracking down the location of a mobile station accurately.

What is the difference between MIMO and beamforming?

MIMO (Multiple Input Multiple Output) antennas operate by breaking high data rate signals into multiple lower data rate signals in Tx mode that are recombined at the receiver. Beamforming arrays are inherently different from MIMO in that the multiple columns of dipoles work together to create a single high gain signal.
