Protecting High Priority Symbols from Beam Switching Delays

Solution Overview

Problem

In wireless communication systems, beam switching can cause delays that impact the circular structure of the channel matrix for CP-orthogonal frequency division multiplexing, leading to loss in error vector magnitude and decoding rate, particularly affecting high priority symbols.

Innovation Solution

A method and apparatus for identifying potential beam switching time spots and determining a time interval configuration to protect high priority symbols from beam switching, by refraining from scheduling these symbols during beam switching times or placing additional symbols to ensure reliability.
