Abstract: According to a communication method of the present disclosure, a responder, after the end of transmission sector sweep (TXSS), receives from an initiator a first feedback frame including a BF training type FIELD indicating whether or not to implement a beam forming training (BFT) of a single user multi-input multi-output (SU-MIMO). If the BF training type FIELD indicates that a BFT of the SU-MIMO is to be implemented, the responder transmits to the initiator a second feedback frame based on the result of the TXSS and including a signal to noise ratio (SNR) and a sector identifier (ID) order. The initiator implements the BFT of the SU-MIMO between the initiator and the responder on the basis of the SNR and the sector ID order.

Abstract: The invention relates to a user equipment for being scheduled with uplink radio resources. The user equipment receives from a radio base station a first-stage uplink resource scheduling message, indicating uplink radio resources usable by the UE to perform an uplink transmission via an unlicensed cell. The receiver further receives a second-stage uplink resource scheduling message, which is related to the first-stage uplink resource scheduling message. Upon reception of the second-stage uplink resource scheduling message, a processor of the UE determines that an uplink transmission is scheduled in case the first-stage uplink resource scheduling message is valid. The first-stage uplink resource scheduling message is determined valid based on a determination as to whether an uplink transmission has been triggered by another second-stage uplink resource scheduling message within a predetermined time period prior to reception of the second-stage uplink resource scheduling message. The UE then performs an uplink transmission.

Abstract: A device monitoring method includes: receiving a message transmitted from a first device to a second device and addressed to the second device; determining whether the message contains a device control command for controlling the second device; if the message contains the device control command, further determining whether to transmit the message to the second device based on a predetermined condition; and when the message is determined to be transmitted to the second device, transmitting the message to the second device. The predetermined condition includes a first condition that the first device is registered as a device having a predetermined function in a device list containing information about whether each of the devices is a device having the predetermined function. The message is determined to be transmitted to the second device when the predetermined condition is satisfied.

Abstract: UEs each monitor a search space in multiple CORSETs and appropriately detect a DCI. In a base station (100), a DCI generator (102) selects one of multiple cases each indicating a combination of CORSETs to be monitored by a terminal (200) among multiple control channel regions (CORSETs). A transmitter (106) indicates, by higher-layer signaling, configuration information indicating the multiple cases, and indicates the selected case by dynamic signaling.

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 (103) generates, as information for an AID12 subfield, information that is different from an AID. The Trigger frame generator (104) 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 (103). The wireless transmitter/receiver (106) transmits the Trigger frame, generated by the Trigger frame generator (104), to a terminal (200).

Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry, in operation, for each coefficient of a plurality of coefficients included in a block, determines a base level relating to Context-Based Adaptive Binary Arithmetic Coding (CABAC) for the coefficient, and encodes an absolute value of the coefficient. In determining the base level, when one or more flags are used in encoding the absolute value of the coefficient, the base level is determined to be a first value, and when one or more flags are not used in the encoding, the base level is determined to be a second value that is smaller than the first value. In encoding the absolute value of the coefficient, when one or more flags are not used, a rice parameter is determined based on the base level which is equal to the second value, and the coefficient is binarized using the rice parameter.
