WIRELESS COMMUNICATION DEVICE AND WIRELESS COMMUNICATION METHOD INCLUDING HISTORY OF UPLINK MULTI-USER TRANSMISSION

KABUSHIKIKAISHA TOSHIBA, ...

1. A wireless communication device, comprising:a receiver configured to receive a first frame instructing the wireless communication device to perform uplink multi-user transmission; and
a transmitter is configured to transmit a second frame in the uplink multi-user in response to the first frame; and
controlling circuitry configured to set a timer upon receiving the first frame, and change a value of a first parameter of accessing a wireless medium when the timer times out,
wherein the receiver is configured to receive a third frame including information that indicates a value for setting the timer,
wherein the controlling circuit is configured to set the timer based on the information included in the third frame, and
wherein the first parameter is a parameter used for determination of a duration of carrier sensing on the wireless medium.

ELECTRONIC APPARATUS AND WIRELESS COMMUNICATION METHOD

KABUSHIKIKAISHA TOSHIBA, ...

1. An electronic apparatus, comprising:transmission circuitry configured to transmit a first request of power feeding;
power reception circuitry configured to receive a first wireless signal of power feeding in response to the first request, and charge a rechargeable battery with a power from the first wireless signal; and
controlling circuitry configured to measure a length of time between the reception of the first wireless signal and the transmission of the first request and to determine a transmission timing of a second request of power feeding based on the measured length of time,
wherein the transmission circuitry is configured to transmit the second request when a remaining amount of power of the rechargeable battery becomes a threshold or less at the transmission timing,
wherein the controlling circuitry is configured to determine the transmission timing of the second request by changing the threshold.
