Splet01. feb. 2024 · Whereas from Release 13, the PDSCH supports beamforming and hence, has DMRS for the channel estimation. Fig. 1 presents the transmission of the physical layer signals in both Release 8 and 13. CRS is common for all the users, and beamforming CRS would impact the performance of cell search and synchronization. SpletFor the reason as explained here, we would use beamforming (Massive MIMO based beamforming), for the implementaion of beamforming controlling the phase of the signal is critical and it is difficult to control the phase of the signal with narrow subcarrier spacing (Ref [33]). As frequency goes higher, the degree of phase noise would increase.
