means for receiving a wake-up signal; and

means for determining, in response to the wake-up signal indicating to skip one of the scheduled ON times, whether to measure a positioning signal.

14. A positioning signal processing method at a user equipment, the method comprising:

operating the user equipment in a discontinuous reception mode including time interleaved scheduled ON times and scheduled OFF times, wherein for each of the scheduled ON times the user equipment is in an active mode monitoring for a positioning signal measurement trigger signal, and wherein for each of the scheduled OFF times the user equipment is in an inactive mode;

receiving a wake-up signal at the user equipment; and

determining, at the user equipment and in response to the wake-up signal indicating to skip one of the scheduled ON times, whether to measure a positioning signal.

15. The method of claim 14 , further comprising measuring the positioning signal, in response to the wake-up signal indicating to skip the scheduled discontinuous reception mode ON time, without monitoring for the positioning signal measurement trigger signal.
