With the rapid development of mobile Internet and Internet of Things(IoT), Telecom services have been increasingly multifarious. The three main usage scenarios for 5G, namely1. enhanced Mobile Broadband(eMBB) 2. massive Machine Type of Communication(mMTC) 3. ultra-Reliable Low Latency Communication(uRLLC), However, in terms of performance, the current 4G system cannot meet the requirements of high peak…
Date Rate Throughput defined in 3GPP 38.306(4.1.2) The DL and UL max data rate supported by the UE is calculated by band or band combinations supported by the UE. AUE supporting NR (NR SA, MR-DC) shall support the calculated DL and UL max data rate defined. In NR Data rate calculated based on the resource…
SIB1 contains information relevant when evaluating if a UE is allowed to access a cell and defines the scheduling of other system information. It also contains radio resource configuration information that is common for all UEs and barring information applied to the unified access control.

The 5G NR radio access network is comprised of these protocol entities: Service data adaptation protocol (SDAP) Packet data convergence protocol (PDCP) Radio link control (RLC) Medium access control (MAC) Physical layer (PHY)
* Signalling radio bearers Signalling Radio Bearers” (SRBs) define as Radio Bearers (RBs) that can be used only for the transmission of RRC and NAS messages.
Multi-Radio Dual Connectivity: Multi-Radio Dual Connectivity (MR-DC) is a generalization of the Intra-E-UTRA Dual Connectivity (DC) described in TS 36.300 [2], where a multiple Rx/Tx capable UE may be configured to utilize resources provided by two different nodes connected via non-ideal backhaul, one providing NR access and the other one providing either E-UTRA or NR…
