What is MeNB and SeNB?

Master eNB (MeNB) is the eNB which terminates at least S1-MME or both S1-MME and S1-U. Secondary eNB (SeNB) is the eNB that is providing additional radio resources.

What is eNB and gNB?

gNB is the 5G radio base station, whereas ng-eNB is an upgraded version of the 4G LTE base station. 5G networks use a radio technology called New Radio – NR. 5G NR and 4G LTE networks will co-exist for a long time to cater to a wide range of customer use cases.

What is the difference between DC and CA?

CA is for the scenarios where the backhaul between nodes is ideal, while DC is for non-ideal backhaul, e.g., relatively large delay between nodes. In CA, there is only one common C-RNTI across all component carriers, and there is only one PUCCH which is on PCell.

What is the meaning of EVDO?

Evolution-Data Optimized
Evolution-Data Optimized (EV-DO, EVDO, etc.) is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access.

What is ENDC in LTE?

ENDC stands for E-UTRAN New Radio – Dual Connectivity, in standards parlance. According to 3GPP standards documents, ENDC allows user equipment to connect to an LTE enodeB that acts as a master node and a 5G gnodeB that acts as a secondary node.

What is MCG and SCG in LTE?

Abstract— Dual Connectivity in LTE network can significantly improve per-user throughput and mobility robustness by allowing users to be connected simultaneously to master cell group (MCG) and secondary cell group (SCG) via MeNB (master eNB) and SeNB (secondary eNB), respectively.

What is LTE eNB?

E-UTRAN Node B, also known as Evolved Node B (abbreviated as eNodeB or eNB), is the element in E-UTRA of LTE that is the evolution of the element Node B in UTRA of UMTS. Traditionally, a Node B has minimum functionality, and is controlled by a Radio Network Controller (RNC).

What is eNodeB in LTE?

eNodeB is a 3GPP-compliant implementation of 4G LTE base station. It consists of independent Network Functions, which implement 3GPP-compliant LTE RAN protocols namely: PHY, MAC, RLC, PDCP, RRC, S1AP see Figure below.

What is DC in LTE?

Dual connectivity (DC) is a LTE Rel-12 feature for small cell enhancement. Similar to carrier aggregation (CA), it aims to utilize the radio resource within multiple carriers to improve UE throughput.

What is dual connectivity in LTE?

Abstract: Dual Connectivity in LTE network can significantly improve per-user throughput and mobility robustness by allowing users to be connected simultaneously to master cell group (MCG) and secondary cell group (SCG) via MeNB (master eNB) and SeNB (secondary eNB), respectively.

What is EVDO LTE?

1xEV-DO (EVDO) is a 3G standard for CDMA-based networks. As a 3G technology, it focuses on bringing high-speed data to CDMA networks. See: 3G. EVDO provides data rates over 10 times faster than 1xRTT, the previous data technology for CDMA networks. EVDO is not as fast as the newer LTE 4G standard.

What is 4G vs LTE?

In laymans terms, the difference between 4G and LTE is that 4G is faster than LTE. The reason for this is that 4G meets the technical standards designated for it whereas LTE data transfer speed standard is merely a stopgap measure standard devised until actual 4G speed is realized.

How to calculate FDD BW and UL throughput for LTE?

DL/UL Throughput calculation for LTE FDD BW = 20 MHz Multiplexing scheme = FDD UE category = Cat 3 Modulation supported = per Cat 3 TBS index 26 for DL (75376 for 100 RBs) and 21 for UL (51024 for 100 RBs) Throughput = # of Chains x TB size.

How to calculate peak data rate in LTE?

The LTE throughput calculation is based on modulation type, TBS index and TBS size. Let us understand peak data rate or LTE throughput calculation with following LTE system configuration. 20MHz channel, 4×4 MIMO configuration, Theoretically, Peak Data rate= No. of REs per subframe x no. of bits per modulation symbol

What is the difference between LTE FDD and TDD version?

Following table summarizes LTE FDD and TDD versions.It compares both with respect to application,frame structure, Guard period,frequency band,interference,data rate and interoperability with other RATs. FDD version is used where both uplink and downlink data rates are symmetrical.

Does 3GPP LTE support TDD and FDD multiplexing?

3GPP LTE technology support both TDD and FDD multiplexing. The paper describes all the factors which affect the throughput like Bandwidth, Modulation, UE category and mulplexing. It also describes how we get throughput 300Mbps in DL and 75Mbps in UL and what are assumptions taken to calculate the same.
