Aspects of the disclosure provide a method for timing and frequency tracking and paging detection. The method can include performing a timing and frequency tracking based on a timing/frequency tracking reference signal (RS) at a user equipment (UE) in a beam formed wireless communication system, and performing a paging detection at a first paging occasion (PO) that is quasi-co-located (QCLed) with the first timing/frequency tracking RS. The first timing/frequency tracking RS is one of a sequence of timing/frequency tracking RSs transmitted on beams of a beam sweeping, and is associated with a beam index. The first PO is within a PO window that includes a sequence of POs transmitted on beams of a beam weeping, and is associated with the same beam index as the first timing/frequency tracking RS.
