Abstract
A communication apparatus determines that communication with another communication apparatus as a transmission destination of a signal generated by a wake-up radio (WUR) conforming to the Institute of Electrical and Electronics Engineers (IEEE) 802.11ba standard, has been disconnected, based on communication conforming to the IEEE 802.11 series standard, and performs control to stop transmission of a predetermined signal performed by the WUR.
Claims15
A communication apparatus, comprising:
- one or more memories having instructions stored therein;
- and
- one or more processors that, upon execution of the instructions, are configured to:
- determine whether communication with a first other communication apparatus has been disconnected, based on communication by a primary connectivity radio (PCR) conforming to Institute of Electrical and Electronics Engineers (IEEE) 802.11 series standard, the first other communication apparatus being a transmission destination of a signal to be generated by a wake-up radio (WUR) conforming to IEEE 802.11ba standard;
- determine, in a case where communication with said first other communication apparatus is determined to have been disconnected, whether no other communication apparatus as being the transmission destination of the signal is present, and
- perform control to stop transmission of the signal performed by the WUR in a case where no other communication apparatus as being the transmission destination is determined to be present, while not to stop transmission of the signal performed by the WUR in a case where a second other communication apparatus as being the transmission destination is determined to be present, the second other communication apparatus being different from the first other communication apparatus.
3 more elements
A method of controlling a communication apparatus, the method comprising:
- determining whether communication with a first other communication apparatus has been disconnected, based on communication by a primary connectivity radio (PCR) conforming to IEEE 802.11 series standard, the first other communication apparatus being a transmission destination of a signal to be generated by a WUR conforming to IEEE 802.11ba standard;
- determining, in a case where communication with said first other communication apparatus is determined to have been disconnected, whether no other communication apparatus as being the transmission destination of the signal is present, and
- performing control to stop transmission of the signal performed by the WUR in a case where no other communication apparatus as being the transmission destination is determined to be present, while not to stop transmission of the signal performed by the WUR in a case where a second other communication apparatus as being the transmission destination is determined to be present, the second other communication apparatus being different from the first other communication apparatus.
A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a method of controlling a communication apparatus, the method comprising:
- determining whether communication with a first other communication apparatus has been disconnected, based on communication by a primary connectivity radio (PCR) conforming to IEEE 802.11 series standard, the first other communication apparatus being a transmission destination of a signal to be generated by a WUR conforming to IEEE 802.11ba standard;
- determining, in a case where communication with said first other communication apparatus is determined to have been disconnected, whether no other communication apparatus as being the transmission destination of the signal is present, and
- performing control to stop transmission of the signal performed by the WUR in a case where no other communication apparatus as being the transmission destination is determined to be present, while not to stop transmission of the signal performed by the WUR in a case where a second other communication apparatus as being the transmission destination is determined to be present, the second other communication apparatus being different from the first other communication apparatus.
