Abstract
A wireless sensing system that senses presence, position, or behavior of an object by a radio wave used for wireless communication, and communicates with a device, includes a wireless sensing device including a wireless communication device, a memory, and a processor configured to, before executing sensing, based on a request for data communication from the device, allocate wireless resources to be used for data communication and the sensing.
Claims16
A wireless sensing system that senses presence, position, or behavior of an object by a radio wave used for wireless communication, and communicates with a device, the wireless sensing system comprising:
- a wireless sensing device including a wireless communication device, a memory, and a processor configured to, before executing sensing, based on a request for data communication from the device, allocate wireless resources to be used for data communication and the sensing, wherein
- when there is a request for data communication in which the wireless resources for the data communication overlap with the wireless resources for the sensing, and a frequency band used for the sensing includes a frequency band of 28 GHz or higher among a plurality of frequency bands available for the sensing, the processor preferentially allocates the wireless resources in the frequency band of 28 GHz or higher to the sensing, and
- when the frequency band used for the sensing includes a frequency band of less than 28 GHz among the plurality of frequency bands available for the sensing, the processor changes the frequency band used for the sensing to a frequency band in which there is no request for data communication.
A resource allocation method executed by a wireless sensing device that senses presence, position, or behavior of an object by a radio wave used for wireless communication, and communicates with a device, the resource allocation method comprising:
- allocating, before executing sensing, based on a request for data communication from the device, wireless resources to be used for data communication and the sensing;
- when there is a request for data communication in which the wireless resources for the data communication overlap with the wireless resources for the sensing, and a frequency band used for the sensing includes a frequency band of 28 GHz or higher among a plurality of frequency bands available for the sensing, preferentially allocating, the wireless resources in the frequency band of 28 GHz or higher to the sensing;
- and
- when the frequency band used for the sensing includes a frequency band of less than 28 GHz among the plurality of frequency bands available for the sensing, changing the frequency band used for the sensing to a frequency band in which there is no request for data communication.
A non-transitory computer-readable recording medium having electromagnetically-readable instructions stored thereon, which when executed, cause a wireless sensing device that senses presence, position, or behavior of an object by a radio wave used for wireless communication, and communicates with a device, to execute a process comprising:
- allocating, before executing sensing, based on a request for data communication from the device, wireless resources to be used for data communication and the sensing;
- when there is a request for data communication in which the wireless resources for the data communication overlap with the wireless resources for the sensing, and a frequency band used for the sensing includes a frequency band of 28 GHz or higher among a plurality of frequency bands available for the sensing, preferentially allocating, the wireless resources in the frequency band of 28 GHz or higher to the sensing;
- and
- when the frequency band used for the sensing includes a frequency band of less than 28 GHz among the plurality of frequency bands available for the sensing, changing the frequency band used for the sensing to a frequency band in which there is no request for data communication.
