WebbA major innovation in 5G NR is the ability to transmit data with multiple Orthogonal Frequency Division Multiplexing (OFDM) subcarrier spacings (SCS). The problem is how to efficiently allocate the frequency-domain resources using different SCSs, given different SCSs result in different Physical Resource Block (PRB) sizes and therefore ...

WebbLTE: Sounding Reference Signal Procedure. The Sounding Reference Signal (SRS) is a reference signal transmitted by the UE in the uplink direction which is used by the eNodeB to estimate the uplink channel quality over a wider bandwidth. The eNodeB may use this information for uplink frequency selective scheduling. floor furniture feed

Webbfigure 1. The other aspect of DSS design is to fit the 5G NR reference signals within the subframes in a way to avoid affecting NR downlink measurements and synchronization. For that, DSS considers the options shown in figure 1 to ensure NR reference signals such as Synchronization Signal Block (SSB) or Demodulation Reference Signal (DMRS) are WebbUsing SRS: Sounding Reference Signals (i.e.SRSs) are transmitted by UEs and received by gNB. These signals are used to monitor uplink channel quality. UEs are configured with multiple SRSs for beam management purposes. They can span about 1 to 4 OFDM symbols and occupy portion of the bandwidth allocated to UE.
