Cyclic prefix duration extension by resource element skipping

A method of wireless communication, comprising:

• determining that a beam change is to occur during a symbol;
• allocating bits to a subset of resource elements for the symbol in a frequency domain allocation, wherein each resource element of the subset of resource elements is spaced apart by a number of empty resource elements;
• performing an inverse fast Fourier transform (IFFT) on the resource elements to generate a time domain signal;
• and
• transmitting the time domain signal during the symbol, wherein the time domain signal includes a number of repetitions of a transmitted waveform equal to the number of empty resource elements between each resource element of the subset of resource elements plus one.

An apparatus for wireless communication by a user equipment (UE), comprising:

• a memory storing computer-executable instructions;
• and
• at least one processor coupled to the memory and configured to execute the computer-executable instructions to:
• determine that a beam change is to occur during a symbol;
• receive a time domain signal during at least a portion of the symbol,
• wherein the time domain signal includes a number of repetitions of a waveform;
• perform a fast Fourier transform (FFT) on the time domain signal;
• and
• determine transmitted bits or a channel from a subset of resource elements output from the FFT for a frequency domain allocation, wherein each resource element of the subset of resource elements is spaced apart by a number of empty resource elements equal to the number of repetitions of the waveform minus one.

An apparatus for wireless communication by a transmitting device, comprising:

• a memory storing computer-executable instructions;
• and
• at least one processor coupled to the memory and configured to execute the computer-executable instructions to:
• determine that a symbol is a first symbol after a beam change;
• allocate bits to a subset of resource elements for the symbol in a frequency domain allocation, wherein each resource element of the subset of resource elements is spaced apart by a number of empty resource elements;
• perform an inverse fast Fourier transform (IFFT) on the resource elements to generate a time domain signal;
• and
• transmit the time domain signal during the symbol, wherein the time domain signal includes a number of repetitions of a transmitted waveform equal to the number of empty resource elements between each resource element of the subset of resource elements plus one.
