Improved dynamic reference signal pattern control

By generating a set of pilot modes S and designing pilot symbols using partial orthogonality rules, the receiver autonomously detects the modes, solving the resource consumption and latency problems caused by explicit signaling, achieving efficient dynamic reference signal mode switching, improving spectral efficiency and reducing latency.

AI Technical Summary

⚠Technical Problem

In existing technologies, switching dynamic reference signal modes requires explicit signaling, which leads to resource consumption and latency, affecting system performance.

⚗Method used

By generating a set of pilot modes S and designing pilot symbols using partial orthogonality rules, the receiver can autonomously detect the mode being used without explicit signaling, thus achieving dynamic adaptive reference signal mode switching.

🎯Benefits of technology

It enables dynamic reference signal mode switching without explicit signaling, improving spectral efficiency and reducing latency, and adapting to different radio conditions.

Abstract

Measures for improved dynamic reference signal mode control are proposed. Such measures exemplarily include, for a communication peer, selecting a reference signal symbol pattern from a plurality of reference signal symbol patterns based on radio channel conditions between the device and the communication peer, wherein for each pair of a first reference signal symbol pattern and a second reference signal symbol pattern among the plurality of reference signal symbol patterns: the first reference signal symbol pattern includes a first number of reference signal symbols, the second reference signal symbol pattern includes a second number of reference signal symbols, and the first number and the second number are different from each other; at least one reference signal symbol in the first reference signal symbol pattern and at least one reference signal symbol in the second reference signal symbol pattern, respectively arranged at the same position in the time domain, are orthogonally encoded to each other; and transmitting a signal embedded in the reference signal symbol pattern.
