Abstract: A power reception apparatus performs device authentication on a power transmission apparatus, and performs control to request first power of the power transmission apparatus in a case where the power transmission apparatus fails the device authentication and to request second power higher than the first power of the power transmission apparatus in a case where the power transmission apparatus successfully passes the device authentication. In addition, the power reception apparatus sets a setting to permit requesting the second power of a power transmission apparatus which does not have a function for responding to the device authentication.

Abstract: In a case where a power reception apparatus 101 is capable of communicating with a power transmission apparatus 102 using a second communication unit 207 configured to perform communication faster than communication performed by a first communication unit 206, the power reception apparatus 101 performs authentication on the power transmission apparatus 102 using the second communication unit 207. In a case where the power reception apparatus 101 is incapable of communicating with the power transmission apparatus 102 using the second communication unit 207, the power reception apparatus 101 performs the authentication on the power transmission apparatus 102 using a communication unit configured to perform communication slower than the communication performed by the second communication unit 207.

Abstract: A power receiving apparatus 101 transmits information representing three or more received powers used in calculating a parameter used in a detection processing by a transmitting apparatus 102. At that time, a relationship P1<P2<P3 is satisfied, where P1 is a first received power which information transmitted an n-th time represents (n is an integer of one or greater), P2 is a second received power which information transmitted an n+1-th time represents, and P3 is a third received power which information transmitted an n+2-th time represents.

Abstract: A power receiving apparatus comprises a power receiving unit for wirelessly receiving power from a power transmitting apparatus, and a communication unit for communicating with the power transmitting apparatus. The power receiving apparatus determines, on the basis of foreign object existence information obtained from the power transmitting apparatus via the communication unit, one state from at least three states including a first state in which a foreign object exists in a power-transmittal range of the power transmitting apparatus, a second state in which a foreign object possibly exists in the power-transmittal range, and a third state in which a foreign object does not exist in the power-transmittal range. The power receiving apparatus performs a first notification when the first state is determined and perform a second notification different from the first notification, when the second state is determined.

Abstract: A communication apparatus, which has a first communication function for executing communication based on a Neighbor Awareness Network (NAN) and a second communication function for executing communication by a wireless LAN by sharing at least a part of a communication circuit with the first communication function, searches a printer by determining whether a value of a Service ID or a value of Service Info of a NAN Attribute included in a Publish message received by the first communication function is a value indicating a print service, and transmits print data to a printer discovered by the search.

Abstract: A communication apparatus changes information to be included in an advertising packet based on reception of a predetermined signal conforming to Bluetooth® Low Energy standard from another communication apparatus.

Abstract: A power reception device includes power reception unit configured to receive wirelessly power from a power transmission device, and display control unit configured to cause information indicating a battery remaining amount of a different power reception device to be displayed on a display unit of the power reception device in a case where power is received by the power reception unit.

Abstract: In a communication system including a first apparatus and a second apparatus, the first apparatus transmits to the second apparatus a signal that requests information for connecting to a network. Then, in response to receiving the signal from the first apparatus, the second apparatus determines whether or not another apparatus connectable to the network is present within a communicable range of the second apparatus, and when determining that the other apparatus is present in the communicable range, the second apparatus notifies the first apparatus of information for connecting to the other apparatus. The first apparatus receives from the second apparatus the information for connecting to the other apparatus, and connects to the other apparatus and to the network, based on the received information.
