Dynamic blanking within physical resource blocks

A method for dynamically adjusting physical resource block usage on a cellular network, the method comprising:

• determining, by the cellular network, that a primary entity is exercising its priority to spectrum overlapping a plurality of physical resource blocks (PRBs) that is used by the cellular network for communication with a plurality of user equipment (UE);
• measuring, by the cellular network, signal strengths of wireless transmissions by the primary entity on a plurality of frequency bands overlapping the plurality of PRBs;
• determining, by the cellular network, a frequency band of the plurality of frequency bands being used by the primary entity based on measuring the signal strengths of wireless transmission by a system of the primary entity;
• identifying, by the cellular network, a plurality of subcarriers of the plurality of PRBs, wherein the plurality of subcarriers overlaps the frequency band;
• selecting, by the cellular network, a predefined Physical Random Access Channel (PRACH) format from a plurality of predefined PRACH formats based at least in part on the identified plurality of subcarriers;
• selecting, by the cellular network, a predefined Physical Uplink Control Channel (PUCCH) format from a plurality of predefined PUCCH formats based at least in part on the identified plurality of subcarriers;
• and
• transmitting, by the cellular network, a first indication of the selected predefined PRACH format, a second indication of the selected predefined PUCCH format, or both to the plurality of UE communicating with the cellular network.
