Beam management for sensing

A sensing node, comprising:

• one or more memories;
• one or more transceivers;
• and
• one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
• receive, via the one or more transceivers, from a network entity, a configuration to use one hybrid beamforming codebook for transmit beamforming for both communication and sensing, wherein the one hybrid beamforming codebook for transmit beamforming defines one or more transmit beams for both communication and sensing;
• and
• transmit, via the one or more transceivers, one or more reference signals based on the one hybrid beamforming codebook for transmit beamforming, wherein each transmit beam of the one or more transmit beams uses fewer transmit antenna elements than a corresponding transmit beam for communications only.

A sensing node, comprising:

• one or more memories;
• one or more transceivers;
• and
• one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
• detect a trigger to use a reduced set of transmit antenna elements of a transmit antenna array of the sensing node, a reduced set of receive antenna elements of a receive antenna array of the sensing node, or both;
• and
• transmit, via the one or more transceivers, one or more sensing reference signals, wherein at least a subset of transmit antenna elements of the transmit antenna array adjacent to the receive antenna array are disabled, at least a subset of receive antenna elements of the receive antenna array adjacent to the transmit antenna array are disabled, or both during transmission of the one or more sensing reference signals.
