Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a preamble in a direction using beamforming. The UE may receive an echo based at least in part on the preamble transmitted in the direction. The UE may detect a presence of a person based at least in part on a power level associated with the echo satisfying a threshold. Numerous other aspects are described.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- transmit a preamble in a direction using beamforming;
- receive an echo based at least in part on the preamble transmitted in the direction;
- and
- detect a presence of a person based at least in part on a power level associated with the echo satisfying a threshold.
A method of wireless communication performed by a user equipment (UE), comprising:
- transmitting a preamble in a direction using beamforming;
- receiving an echo based at least in part on the preamble transmitted in the direction;
- and
- detecting a presence of a person based at least in part on a power level associated with the echo satisfying a threshold.
A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
- transmit a preamble in a direction using beamforming;
- receive an echo based at least in part on the preamble transmitted in the direction;
- and
- detect a presence of a person based at least in part on a power level associated with the echo satisfying a threshold.
An apparatus for wireless communication, comprising:
- means for transmitting a preamble in a direction using beamforming;
- means for receiving an echo based at least in part on the preamble transmitted in the direction;
- and
- means for detecting a presence of a person based at least in part on a power level associated with the echo satisfying a threshold.
