About This Course

This practice-only course is a focused question bank with 300+ hand-crafted questions and answers on the 5G NR Physical Layer. The questions are designed around concepts that are also highly relevant to 4G/LTE PHY and future 6G physical-layer discussions, so solving them will strengthen your fundamentals across generations.

You will not just "read" theory here β€” you will solve questions and immediately see the correct answers with clear explanations. Every question is designed to mirror the kind of problem you encounter in 5G PHY interviews at modem vendors, OEMs, operators, and startups.

If you are serious about 5G NR Physical Layer interviews, this question bank will help you evaluate where you stand β€” and what you need to revise β€” before entering the interview room.

What You Get

βœ“ 300+ interview-style questions on 5G NR Physical Layer
βœ“ A mix of single-correct MCQs and integer-type numericals
βœ“ Immediate feedback β€” correct answer + explanation after each question
βœ“ Multiple difficulty levels β€” from fundamentals to advanced interview-style problems
βœ“ Covers concepts relevant to 4G LTE PHY and future 6G physical-layer discussions too

Topics Covered

Questions span the full 5G NR Physical Layer curriculum, including:

β€’ OFDM, numerologies, CP, and spectrum usage
β€’ Resource grid, slots, symbols, RBs, and BWPs
β€’ Synchronisation: SS/PBCH block, PSS, SSS, PBCH
β€’ PDCCH, PDSCH, PUCCH, PUSCH, PRACH
β€’ DMRS, CSI-RS (ZP/NZP, CSI-IM), SRS, PTRS
β€’ Modulation, coding, MCS, TBS, throughput calculation
β€’ HARQ, retransmissions, code block groups, timing
β€’ MIMO, rank, precoding, beamforming, beam management
β€’ Power control concepts at PHY level
β€’ Timing advance, TA calculation, and coverage impact
β€’ Initial access and random access procedure (RA/PRACH)
β€’ RRC parameters affecting PHY behaviour (SSB, PUCCH-Config, TDD patterns…)
β€’ Measurement and reporting concepts (RRC ↔ PHY)
β€’ Practical PHY scenarios relevant to real deployments and lab testing

Who This Course is For

  • β†’ 4G/5G PHY engineers preparing for modem/RAN/Layer-1 roles
  • β†’ L2/MAC/RF/RNO engineers who want to move closer to PHY design and development
  • β†’ Working professionals preparing for interviews at 5G companies (modem vendors, OEMs, operators, startups)
  • β†’ Students and fresh graduates who already know basic 4G/5G and want interview-oriented PHY practice
  • β†’ Engineers interested in 6G who want to solidify their 4G/5G PHY foundations first

Prerequisites

β†’ Familiarity with basic 4G/5G concepts, especially OFDM and the NR/LTE physical-layer building blocks
β†’ This is a practice-only course β€” assumes you have studied theory elsewhere and now want to test and deepen your understanding
