In 1-bit ISAC channels with receiver CSI, communication and sensing capacities are simultaneously achievable with no trade-off via constant-amplitude rotationally symmetric inputs; with transmitter CSI, optimal power control shifts from opportunistic to uniform allocation as sensing priority rises.

Fundamental Limits of 1-bit ISAC Systems: Capacity Region and Optimal Power Control
In 1-bit ISAC channels with receiver CSI, communication and sensing capacities are simultaneously achievable with no trade-off via constant-amplitude rotationally symmetric inputs; with transmitter CSI, optimal power control shifts from opportunistic to uniform allocation as sensing priority rises.
