5G Standalone Architecture – RRC Inactive State

The show must go on, so at some point, network operators will start putting 5G core networks in place which means that mobile devices will use the 5G NR Standalone (SA) air interface for signaling instead of LTE anchor cells. So I had a look at 3GPP TS 38.331 which contains the Radio Resource Control … Continue reading 5G Standalone Architecture – RRC Inactive State

5G RRC Protocol And How It Compares to 4G RRC

Recently I’ve been looking a bit at the 5G NR Radio Resource Control (RRC) protocol in 3GPP TS 38.311 to get an idea how it is structured and how it compares to the LTE RRC protocol specified in 3GPP TS 36.331. As Ralf points out in the comments below (thanks very much!) some parts of … Continue reading 5G RRC Protocol And How It Compares to 4G RRC
