Abstract: A communication apparatus in the present disclosure comprises an AID generator, a Trigger frame generator, and a wireless transmitter/receiver. When a Trigger Type in a trigger frame is an RA trigger, the AID generator generates, as information for an AID12 subfield, information that is different from an AID. The Trigger frame generator generates a RA variant Trigger frame when the Trigger Type in the trigger frame is an RA trigger, and sets, in the AID12 subfield included in the RA variant Trigger frame, the information output from the AID generator. The wireless transmitter/receiver transmits the Trigger frame, generated by the Trigger frame generator, to a terminal.

Abstract: An image encoder includes circuitry and a memory, wherein the circuitry, in operation, determines whether inter prediction is to be applied to a current block; in response to determining that the inter prediction is to be applied to the current block, performs a partition prediction process; and, in response to determining that the inter prediction is not to be applied, encodes the current block without using the partition prediction process. The partition prediction process includes predicting first values of a set of pixels between a first partition and a second partition in the current block, using a first motion vector for the first partition; predicting second values of the set of pixels, using a second motion vector for the second partition; weighting the first values and the second values; and generating a prediction image for the current block using the weighted first values and the weighted second values.

Abstract: A drone control system includes a destination determiner and a movement instructor. The destination determiner determines, among standby places, a destination of a drone capable of delivering a package, based on a current location which is a location of the drone at present, standby place locations which are locations of the standby places, and predicted demand information regarding packages in the standby places. The movement instructor instructs the drone to move to the destination determined by the destination determiner.

Abstract: A communication apparatus includes circuitry that determines a number of resource blocks forming a resource block group, which is a unit used to allocate a resource to the communication apparatus, in a first band or in a second band that is an expanded band to which the first band is expanded, and a subcarrier spacing for the second band is same or different from a subcarrier spacing for the first band; and a transceiver that is coupled to the circuitry and that communicates with a base station using the resource. One of the number of resource blocks set for the first band and the number of resource blocks set for the second band is an integer multiple of the other, and the number of resource blocks set for the first band and the number of resource blocks set for the second band are values that are a power of two.

Abstract: A transmission apparatus includes M signal processors that respectively generate modulated signals directed to M reception apparatuses, M being an integer equal to or greater than 2, and an antenna section. Each signal processor modulates a first bit sequence made up of two bits to generate a first modulated signal and a second modulated signal, and modulates a second bit sequence made up of other two bits to generate a third modulated signal and a fourth modulated signal, in a case of transmitting multiple streams to a corresponding one of the M reception apparatuses. The antenna section includes a first antenna that transmits the first modulated signal and the third modulated signal and a second antenna that transmits the second modulated signal and the fourth modulated signal. At least either the signals transmitted from the first antenna or the signals transmitted from the second antenna are phase-changed signals.

Abstract: A communication apparatus includes a receiver and a decoder. The receiver includes a plurality of antenna elements and, in operation, receives from a base station apparatus a modulated signal mapped to one of a plurality of subframes defined in a frame corresponding to a communicable range to which the communication apparatus belongs. The plurality of subframes are defined by time-division, frequency-division, or time-and-frequency division of the frame. A maximum number of modulated signals that can be simultaneously transmitted in a subframe from the base station apparatus varies depending on the communicable range. The decoder, in operation, decodes the received modulated signal.
