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: A three-dimensional data encoding method encodes a plurality of three-dimensional points, and includes: selecting one of two or more prediction modes for calculating a predicted value of an attribute information item of the first three-dimensional point, in accordance with attribute information items of one or more second three-dimensional points in the vicinity of a first three-dimensional point; calculating the predicted value by the selected prediction mode; calculating, as a prediction residual, a difference between a value of the attribute information item of the first three-dimensional point and the calculated predicted value; and generating a bit stream that includes the one prediction mode and the prediction residual.

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.
