Master Thesis: Adaptive Mixed Periodic and Aperiodic SRS Allocation for MU-MIMO

Technology, Data & Digital · Software & Web Development · Software Engineering

In short

This Master Thesis project focuses on efficiently allocating periodic and aperiodic SRS resources for MU-MIMO under varying conditions like traffic load and mobility. The work aims to improve SRS utilization, MU-MIMO layers, throughput, and spectral efficiency through simulation and data analysis.

Responsibilities

  • Evaluate sharing strategies for periodic and aperiodic SRS resources under different traffic loads, UE capabilities, mobility conditions, and TDD configurations.
  • Study when mixed P-SRS/AP-SRS operation outperforms using either mode alone.
  • Investigate prioritization strategies when SRS capacity is exhausted.
  • Analyze the impact on SRS utilization, RAT MU-MIMO layers, throughput, and spectral efficiency.
  • Design and evaluate experiments using relevant simulation, trace, counter, or log data.

Requirements

  • MSc studies in wireless communications, telecommunications, signal processing, computer engineering, or a related field.
  • Solid understanding of 4G/5G NR radio concepts, TDD, uplink and downlink channels, MIMO, beamforming, precoding, CSI, channel estimation, SRS, and DMRS.
  • Understanding of link adaptation and channel measurement parameters such as CQI, RI, MCS, SINR, and BLER.
  • Ability to read technical specifications and internal design documents.
  • Good Python skills for data processing, visualization, and experimentation.
  • Excellent Java skills if Redhawk is used for simulation.
  • Linux and Git experience.
  • Ability to design experiments, analyze logs, and document results clearly.
  • Familiarity with GenAI tools for coding and verification.
