1. A method performed by a network node, the method comprising:
determining an integrity risk (IR) parameter associated with a wireless device, the IR parameter indicating a maximum probability of providing a positioning service that is out of a tolerance range;
transmitting, to the wireless device, positioning assistance information and the IR parameter; and
receiving, from the wireless device, an estimated position and a protection level (PL) parameter, the PL parameter indicating a statistical error bound computed to guarantee that probability of a position error exceeding the PL is less than or equal to the IR.
