Session 3 of the E2E User Plane and RAN Protocol series is now uploaded. This video provides a detailed look at the E2E User Plane and RAN protocols, focusing on TCP and its interaction with PDCP, the TCP handshake process, and various retransmission mechanisms. Topics Covered: * User Plane Data TCP/
This video takes a deep dive into radio protocol, we’ll explore the interplay between TCP/PDCP and PDCP related timers in details .
This video takes a deep dive into radio protocols, simulating the data flow between the UE and gNodeB while breaking down key timers and parameters such as t-Reordering and T-PollRetransmit . Additionally, we’ll explore the interplay between TCP/PDCP and RLC/MAC retransmission-related timers. This video covers the following topics:
Introduction: In general, power design in NR is simpler than in 4G. In NR, a cell's power is shared across multiple channels, and the allocation of power to each channel plays a crucial role in determining the cell's coverage performance. This article discusses the key aspects
Introduction This article will cover the following topics: * NR Slot Format – Introduction * 4G Vs 5G TDD Subframe/Slot format: * NR Slot Format Types Deep dive: Fixed, Semi-Static & Dynamic TDD * Cross Link Interference definition and relation with NR Slot Allocation * 4G/NR coexistence * NR Slot Format Planning and design impact
4G/5G – DL/UL Inter-Cell Interference Randomization Brief Description and expected benefits: * When the Cell Load is low; the g-NB.(Scheduler) staggers the resources allocated to adjacent cells as far away from each other as possible in multi-cell networking scenarios. * Usually the resources allocation will be staggered based on the
Introduction: * UE battery life is an important aspect of the user's experience, which will influence the adoption of 5G NR handsets and/or services. It is critical to study UE power consumption to ensure that UE power efficiency for 5G NR UEs can be better than that of
This video addresses a common limitation in Power BI, where redundant measures were required to calculate the Delta% for Pre/Post date values of specific metrics or KPIs. In this video, we’ll show you how to streamline this process using Calculation Groups. Here's what you'll
Learn about 5G DMRS for PBCH (1) What is the primary function of DMRS for PBCH? * The UE uses DMRS to estimate the propagation channel experience by the PBCH. The resultant information is used to demodulate the PBCH and subsequently decode the Master Information Block. (2) How and where is
