Part 3: Advanced RIS Architectures

Chapter 10: STAR-RIS (Simultaneously Transmitting and Reflecting)

Advanced~200 min

Learning Objectives

  • Distinguish the three STAR-RIS operating protocols: energy splitting, mode switching, time switching
  • State the per-element amplitude and phase constraints for each protocol
  • Derive the STAR-RIS joint sum-rate / coverage optimization
  • Quantify the coverage gain of STAR-RIS over reflecting-only RIS
  • Choose the appropriate protocol for a given deployment (indoor/outdoor, full-space)
