Abstract: In a base station (100), a controller (101) determines one set from among a plurality of sets, each of which including one or more candidates for a resource for an uplink (UL) control channel during initial access, and determines one candidate from among the one or more candidates for the resource, which is included in the determined set. A transmitter (114) indicates the determined set to a terminal (200) by higher layer signaling, and indicates the determined candidate by dynamic signaling. A receiver (116) receives a UL control signal, using the resource corresponding to the determined candidate in the determined set. In the base station, the association between a value to be indicated by the higher layer signaling and the plurality of sets is configured for each of one or more parameters relating to the initial access.

Abstract: At a base station, a control unit selects one combination from multiple combinations of parameters regarding uplink control channel (PUCCH) resources. A transmission unit indicates a terminal of resource settings (Semi-static resource configuration) including the multiple combinations by higher layer signaling, and indicates the terminal of the one combination that has been selected by dynamic signaling (DCI).

Abstract: The present disclosure relates to a mobile terminal for performing cell (re-)selection in a system with at least two suitable cells, each with a plurality of beams. The terminal is in a normal- or a high-mobility state. The terminal measures a signal quality of the beams of each of the suitable cells, determines the cell quality based on the respective measured signal qualities of the beams; and (re-)selects that cell based on a cell (re-)selection criterion using the determined cell qualities. The cell quality is determined for each one of the suitable cells as a sum of the measured signal quality of the beam, with the best signal quality, and a combined beam quality value for the other beams. The combined beam quality value is scaled with a scaling factor which changes depending on the mobility state such that the combined beam quality value is scaled-up in the high-mobility state and scaled-down in the normal-mobility state.

Abstract: A method for analyzing a three-dimensional model of an object which includes: obtaining the three-dimensional model generated based on images of the object, the images being imaged by respective cameras from respective viewpoints, the three-dimensional model including three-dimensional points each of which indicating a position of the object; obtaining a camera parameter of one camera among the respective cameras; generating, based on the camera parameter and the three-dimensional model, a depth image indicating a distance between the one camera and the object; generating a foreground image indicating an area in which the object is present in the one image imaged by the one camera; comparing the depth image and the foreground image to determine whether there is a deficiency of a three-dimensional point in the three-dimensional model; and outputting deficiency information if it is determined that there is the deficiency of the three-dimensional point in the three-dimensional model.

Abstract: A three-dimensional data encoding method includes: generating a bitmap indicating which of pieces of three-dimensional data a three-dimensional point belongs to, the three-dimensional point being included in a unit space; generating a conversion code using a look-up table and the bitmap generated; and generating encoded data including duplicated point information indicating a total number of three-dimensional points included in the unit space, and conversion code information indicating the conversion code. The generating of the conversion code includes: generating the conversion code from the bitmap when the total number of the three-dimensional points included in the unit space is less than or equal to a predetermined threshold value; and generating the conversion code from an inverted bitmap when the total number of the three-dimensional points included in the unit space is greater than the predetermined threshold value, the inverted bitmap being obtained by inverting 0 and 1 included in the bitmap.

Abstract: Provided are a user equipment (UE), a scheduling node, and communication methods for a UE and a scheduling node. The UE comprises a transceiver which, in operation, performs listen before talk, LBT and circuitry which, in operation, performs at least one of: incrementing a counter upon determining LBT failure, starting a triggering timer upon determining LBT failure if the triggering timer is not running, and determining whether the counter has reached a threshold value upon expiry of the triggering timer; and incrementing the counter upon determining a number N of consecutive LBT failures due to ongoing LBT backoff. The circuitry generates a indicating consistent LBT failure upon determining that the counter has reached the threshold value, and the transceiver, in operation, declares consistent LBT failure.

Abstract: Provided is a wireless communication device. A PHICH reception unit determines whether a received signal in a PHICH region is an ACK signal or a NACK signal. When doing so, the PHICH reception unit does not receive a PHICH in a subframe in which a terminal monitors an E-PDCCH. A control signal reception unit outputs a retransmission prompting signal to a signal allocation unit when the signal outputted from the PHICH reception unit is a NACK signal and when a UL grant was not detected. Meanwhile, when a UL grant was detected, the control signal reception unit outputs the detected UL grant to the signal allocation unit. The signal allocation unit maps the transmission signal in accordance with the retransmission prompting signal and the UL grant and transmits the transmission signal from a wireless transmission unit.
