Abstract
The present disclosure describes techniques and systems for beam search pilots for paging channel communications. In some aspects, a user device receives, from a base station of a wireless network, a beam search pilot on a beam. The user device determines that a signal quality of the beam search pilot meets a signal quality threshold. Based on this determination, the user device transmits, to the base station, an indication that the beam search pilot meets the signal quality threshold. The user device then receives a paging channel communication on the beam provided by the base station.
Claims27
A method performed by a user device for using beam search pilots for a paging channel communication, the method comprising:
- receiving a first indication of a beam search pilot schedule of communication resources for receiving the beam search pilots from a base station of a wireless network;
- entering one of a radio resource control-idle (RRC-idle) mode or a radio resource control-inactive (RRC-inactive) mode;
- while in the RRC-idle mode or the RRC-inactive mode, receiving, from the base station, a beam search pilot on an associated beam transmitted by the base station over at least one of the communication resources of the beam search pilot schedule;
- determining that a signal quality of the received beam search pilot meets a signal quality threshold;
- and
- transmitting, to the base station, a second indication that the received beam search pilot meets the signal quality threshold.

A user device comprising:
- a processor;
- a hardware-based transceiver;
- and
- a computer-readable storage medium comprising instructions that, responsive to execution by the processor, direct the user device to:
- receive a first indication of a beam search pilot schedule of communication resources for receiving beam search pilots from a base station of a wireless network;
- enter one of a radio resource control-idle (RRC-idle) mode or a radio resource control-inactive (RRC-inactive) mode;
- while in the RRC-idle mode or the RRC-inactive mode, receive, from the base station and using the hardware-based transceiver, a beam search pilot on an associated beam transmitted by the base station over at least one of the communication resources of the beam search pilot schedule;
- determine that a signal quality of the received beam search pilot meets a signal quality threshold;
- and
- transmit, to the base station and using the hardware-based transceiver, a second indication that the beam search pilot has a signal quality that meets the signal quality threshold.
(canceled)
A base station comprising:
- a processor;
- one or more hardware-based transceivers;
- and
- a computer-readable storage medium comprising instructions that, responsive to execution by the processor, direct the base station to:
- transmit, to a user device, a first indication of a beam search pilot schedule of communication resources for receiving beam search pilots from the base station;
- detect that the user device has entered one of a radio resource control-idle, (RRC-idle) mode or a radio resource control-inactive (RRC-inactive) mode;
- transmit, to the user device and while the user device operates in the RRC-idle mode or the RRC-inactive mode, multiple beam search pilots on multiple beams, respectively;
- and
- receive, from the user device and in response to transmission of the multiple beam search pilots, a second indication that a signal quality of a beam search pilot of the multiple beam search pilots meets a signal quality threshold, the beam search pilot having been transmitted on a beam of the multiple beams.
