In terms of Over The Air(OTA) and Physical Layer perspective, LTE-NR interworking (EN-DC) in NSA(Non-StandAlone) is only one possibility (assuming that LTE always becomes the Anchor), but with the same OTA/Physical layer there can still be multiple possibilities of implementing higher layer bearer.

The carrier for the initial connection setup is called Anchor carrier and the other carriers are called Non-Anchor carrier. When NB-IoT is operating in 'inband with the same PCI' mode, only a specific PRB within the legacy LTE System Band can be configured as Anchor carrier.

Oct 13, 2020 · Short-term DSS enables network operators to deploy 5G NR using their lower frequency bands, typically targeting frequencies below 1 GHz. To date, this is still NSA mode and requires the combination with an LTE anchor, typically mid-band 1 GHz to 3 GHz.

ments. NSA mode requires an LTE anchor carrier for the exchange of control and signaling information. Dual con nectivity allows the 5G-capable device to connect to the 5G radio access network (RAN). With proper configuration, the 5G carrier can coexist with the LTE carrier, sharing the same frequency band. The 5G device will receive that

Feb 5, 2020 · More than 1 layers of LTE can be used as anchors for ENDC/ option 3 to have much easier transition towards NR for SN (SCG) addition, e.g, if LTE having L700, L1800, L2100, multi-anchoring enables all of them to be made anchors simultaneously for NR.

In splitbearer, NR PDCP is used both in LTE Anchor and NR. Now getting further into details, let's think of exactly at which point within PDCP the split happens. According to 38.323 4.2.2 PDCP entities, it is stated as follows : For split bearers, routing is …

May 10, 2021 · Short-term DSS enables network operators to deploy 5G NR using their lower frequency bands, typically targeting frequencies below 1 GHz. To date, this is still non-standalone (NSA) mode and requires the combination with an LTE …

Feb 24, 2024 · For example, 5G NR is deployed in a sub-GHz LTE band and the 1-3 GHz band is the LTE anchor. Alternatively, 5G NR in 3.5 GHz TDD band might have uplink coverage issues. DC plus DSS with low-band LTE FDD improves coverage.

Non-Standalone (NSA) New Radio (NR) is a deployment mode for 5G networks that leverages existing 4G LTE infrastructure to introduce 5G capabilities. Here’s a detailed technical explanation: LTE Anchor: In NSA NR, the LTE network serves as the anchor for control signaling.

Dec 28, 2023 · 5G NSA (Non-Standalone) is an initial deployment strategy for 5G networks that uses the existing 4G LTE network as an anchor for control functions and relies on 4G infrastructure for functions like mobility and coverage.
