Method and apparatus for calculating beamforming based paging occasion in wireless communication system

A wireless device in a wireless communication system, the wireless device comprising:

• a memory;
• a transceiver;
• and
• at least one processor, coupled to the memory and the transceiver, configured to:
• control the transceiver to receive, from a base station, reference signals that are transmitted through multiple transmission (Tx) beams of the base station,
• select a Tx beam of the base station among the multiple Tx beams of the base station,
• identify a time interval mapped to the selected Tx beam among time intervals for a paging channel monitoring in a paging occasion, wherein each of the time intervals is mapped to each of the multiple Tx beams of the base station, and
• monitor a paging channel in the identified time interval.

A processor for a wireless device in a wireless communication system, wherein the processor is configured to control the wireless device to perform operations comprising:

• receiving, from a base station, reference signals that are transmitted through multiple transmission (Tx) beams of the base station;
• selecting a Tx beam of the base station among the multiple Tx beams of the base station;
• identifying a time interval mapped to the selected Tx beam among time intervals for a paging channel monitoring in a paging occasion, wherein each of the time intervals is mapped to each of the multiple Tx beams of the base station;
• and
• monitoring a paging channel in the identified time interval.
