Non-uniform reference signal patterns for positioning and sensing

A device for positioning, sensing, or both performed, the device comprising:

• a transceiver;
• a memory;
• and
• one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
• receive a non-uniform reference signal configuration for positioning, sensing, or both;
• receive a reference signal configured in accordance with the non-uniform reference signal configuration, wherein the reference signal comprises a plurality of subcarriers, and wherein a frequency spacing between different pairs of neighboring subcarriers of the reference signal comprises a plurality of different values;
• and
• determine one or more time of arrival (TOA) measurements used for positioning, sensing, or both based on the received reference signal.

A server for positioning, sensing, or both performed, the server comprising:

• a transceiver;
• a memory;
• and
• one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
• determine a non-uniform reference signal configuration for a reference signal of positioning, sensing, or both, wherein the reference signal comprises a plurality of subcarriers, and wherein according to the non-uniform reference signal configuration, the reference signal is configured such that a frequency spacing between different pairs of neighboring subcarriers of the reference signal comprises a plurality of different values;
• and
• transmit the non-uniform reference signal configuration for determining one or more time of arrival (TOA) measurements based on the reference signal.
