Abstract
A wireless communication device can selectively perform a beam switch upon performing a power-up operation based on the criticality of the beam switch. The wireless communication device can switch from a previously serving downlink beam to a new downlink beam either during or after a paging time window based on beam measurements obtained for the previously serving downlink beam and the new downlink beam. Other aspects, features, and embodiments are also claimed and described.
Claims30
A method for wireless communication at a wireless communication device in a wireless communication network, the method comprising:
- performing a power-up operation of the wireless communication device in an idle mode;
- obtaining a plurality of beam measurements, each beam measurement being associated with a respective downlink beam of a plurality of downlink beams used for communication with a radio access network (RAN) node;
- and
- switching from a first downlink beam of the plurality of downlink beams previously used for communication with the RAN node to a second downlink beam of the plurality of downlink beams after a paging time window when a first beam measurement of the plurality of beam measurements associated with the first downlink beam is greater than a first threshold and a difference between the first beam measurement and a second beam measurement of the plurality of beam measurements associated with the second downlink beam is greater than a second threshold.
A wireless communication device in a wireless communication network, comprising:
- a wireless transceiver configured to receive a plurality of downlink beams used for communication with a radio access network (RAN) node;
- a memory comprising instructions;
- and
- a processor configured to execute the instructions to:
- perform a power-up operation of the wireless communication device in an idle mode;
- obtain a plurality of beam measurements, each beam measurement being associated with a respective downlink beam of the plurality of downlink beams;
- and
- switch from a first downlink beam of the plurality of downlink beams previously used for communication with the RAN node to a second downlink beam of the plurality of downlink beams after a paging time window when a first beam measurement of the plurality of beam measurements associated with the first downlink beam is greater than a first threshold and a difference between the first beam measurement and a second beam measurement of the plurality of beam measurements associated with the second downlink beam is greater than a second threshold.
A wireless communication device in a wireless communication network, comprising:
- means for performing a power-up operation of the wireless communication device in an idle mode;
- means for obtaining a plurality of beam measurements, each beam measurement being associated with a respective downlink beam of a plurality of downlink beams used for communication with a radio access network (RAN) node;
- and
- means for switching from a first downlink beam of the plurality of downlink beams previously used for communication with the RAN node to a second downlink beam of the plurality of downlink beams after a paging time window when a first beam measurement of the plurality of beam measurements associated with the first downlink beam is greater than a first threshold and a difference between the first beam measurement and a second beam measurement of the plurality of beam measurements associated with the second downlink beam is greater than a second threshold.
An apparatus for wireless communication, comprising:
- a memory comprising instructions;
- and
- a processor configured to execute the instructions to:
- perform a power-up operation of the wireless communication device in an idle mode;
- obtain a plurality of beam measurements, each associated with a respective downlink beam of a plurality of downlink beams used for communication with a radio access network (RAN) node;
- and
- switch from a first downlink beam of the plurality of downlink beams previously used for communication with the RAN node to a second downlink beam of the plurality of downlink beams after a paging time window when a first beam measurement of the plurality of beam measurements associated with the first downlink beam is greater than a first threshold and a difference between the first beam measurement and a second beam measurement of the plurality of beam measurements associated with the second downlink beam is greater than a second threshold.
