Abstract: The invention relates to an improved radio resource allocation performed by a vehicular mobile terminal. The vehicular mobile terminal determines whether to determine radio resources based on the location of the vehicular mobile terminal or not, based on information received from an entity of the communication system. In case the radio resources are to be selected based on the location of the vehicular mobile terminal, the vehicular mobile terminal determines the location of the vehicular mobile terminal, and determines radio resources for communication with at least the second mobile terminal, based on the determined location of the vehicular mobile terminal.

Abstract: The present disclosure relates to receiving and transmitting data in a frame with subframes of a wireless communication system, each subframe being either an uplink subframe accommodating uplink signal, a downlink subframe accommodating downlink signal or a special subframe including a downlink signal portion as well as an uplink signal portion. A control signal includes a special subframe configuration specifying the length of the uplink and/or downlink portion of the special subframe. The mapping and demapping of user data and/or control data including feedback information in a transmission time interval, TTI, onto or from one subframe is then performed, wherein the length of a second TTI for mapping onto the uplink portion of a special subframe is shorter than a first TTI for mapping onto an uplink subframe, or a first number of TTIs mapped onto the uplink subframe is larger than a second number of TTIs for mapping onto the uplink portion of a special subframe. The data are received or transmitted accordingly.

Abstract: A transmission device includes a generator that generates a frame in a predetermined frame format and a communicator that transmits the frame generated by the generator. The predetermined frame format includes a first field indicating whether information related to a wake-up process performed by a device that received a frame in the predetermined frame format is valid or not. When the first field indicates that the information is valid, the predetermined frame format further includes a second field indicating identification information identifying the device.

Abstract: A three-dimensional data encoding method includes: calculating coefficient values from pieces of attribute information of three-dimensional points included in point cloud data; quantizing the coefficient values individually to generate quantized values; and generating a bitstream including the quantized values. Each of the coefficient values belongs to any one of layers. In the quantizing, each of the coefficient values is quantized using a quantization parameter for a layer to which the coefficient value belongs among the layers, and the bitstream includes first information and pieces of second information, the first information indicating a reference quantization parameter, the pieces of second information being for calculating quantization parameters for the layers from the reference quantization parameter.

Abstract: An encoder that encodes a moving picture using an inter prediction process, and includes circuitry and memory coupled to the circuitry. In the inter prediction process, when performing a correction process which is a local illumination compensation (LIC) process for a prediction image, the circuitry, in operation; performs the correction process on a prediction image generated using a finally-derived motion vector that is finally derived in a stage before the correction process; and after the correction process, determines, as a final prediction image, the prediction image subjected to the correction process, without applying other correction process on the prediction image.

Abstract: A transmitting multi-link device (MLD) includes circuitry and a transmitter. The circuitry, in operation, constructs an Additional Authentication Data (AAD) and a Nonce, and encapsulates a plaintext medium access control (MAC) protocol data unit (MPDU), the AAD, and the Nonce to generate an encapsulated MPDU. The AAD includes an Address 1 (A1) field, to which a recipient MLD's MAC address is set, and an AAD Address 2 (A2) field, to which the transmitting MLD's MAC address is set. The Nonce includes a Nonce Address 2 (A2) field, to which the transmitting MLD's MAC address is set. The transmitter, in operation, transmits the encapsulated MPDU to the recipient MLD on a first link.
