Abstract: Provided are a base station device and a mobile station device, which can lighten a cell-search processing. The base station device includes a frame constitution unit for forming a frame, in which a pilot symbol multiplied by a base station scrambling code and a plurality of sequences contained in the corresponding sequence set is arranged in at least the head or tail, and a radio transmission unit for sending the formed frame. On the receiving side, the frame timing can be detected from the position of a pilot symbol contained in that frame. Since the base station scrambling code and the sequence set containing the sequences are made to correspond to each other, candidates can be narrowed to at most the base station scrambling codes of the number of the combinations of the sequences contained in the sequence set, by detecting the sequences multiplied by the pilot symbol.

Abstract: The invention relates to a transmitting device for performing an initial and one or more retransmissions of data via a sidelink interface. A receiver and processor perform a resource sensing procedure to acquire information about radio resources usable for the device to transmit data at a later point in time. The processor performs an autonomous radio resource allocation to select time-frequency radio resources within a transmission window to be used for performing a first transmission of the data, based on information acquired by the resource sensing procedure. The processor determines a data transmission timing pattern, that indicates a transmission timing for performing one or more transmissions of data. A transmitter performs the first data transmission using the selected time-frequency radio resources and performs the data retransmissions at the transmission timing defined by the determined data transmission timing pattern with respect to the first data transmission.

Abstract: The present disclosure relates to a resource allocation procedure for allocating time-frequency radio resources by a scheduler in a mobile communication system. A plurality of numerology schemes are defined, each partitioning a plurality of radio resources of the mobile communication system into resource scheduling units in a different manner. A reference resource set is defined per numerology scheme, each being associated to a set of radio resources usable for being allocated according to the respective numerology scheme. The reference resource set of at least one numerology scheme overlaps with the reference resource set of at least another numerology scheme in the frequency and/or time domain. The resource allocation procedure is performed for allocating radio resources to one or more user terminals according to the numerology schemes. The resource allocation procedure is performed for each numerology scheme based on a scheduling time interval defined for the respective numerology scheme.

Abstract: A three-dimensional data encoding method includes encoding information of a current node included in an N-ary tree structure of three-dimensional points included in three-dimensional data, where N is an integer greater than or equal to 2. In the encoding, first information is encoded, the first information indicating a range for one or more referable neighboring nodes among neighboring nodes spatially neighboring the current node, and the current node is encoded with reference to a neighboring node within the range.

Abstract: A transmission method includes mapping processing, phase change processing, and transmission processing. In the mapping processing, a plurality of first modulation signals and a plurality of second modulation signals are generated using a first mapping scheme, and a plurality of third modulation signals and a plurality of fourth modulation signals are generated using a second mapping scheme. In the phase change processing, a phase change is performed on the plurality of second modulation signals and the plurality of fourth modulation signals using all N kinds of phases. In the transmission processing, the first modulation signals and the second modulation signals are respectively transmitted at a same frequency and a same time from different antennas, and the third modulation signals and the fourth modulation signals are respectively transmitted at a same frequency and a same time from the different antennas.

Abstract: A key management method serves as an electronic control unit (ECU) in an onboard network system having a plurality of ECUs that perform communication by frames via a network. The method includes storing a shared key and executing encryption processing based on the shared key. The method further includes executing inspection of a security state of the shared key stored in a case where a vehicle is in at least one of the following particular states: the vehicle is not driving and is an accessory-on state; a fuel cap of the vehicle is open, and the vehicle is not driving and is fueling; the vehicle is parked, which is indicated by the gearshift; the vehicle is in a stopped state before driving, which is indicated by the gearshift; and a charging plug is connected to the vehicle, and the vehicle is electrically charging.
