Abstract: When a plurality of the subcarrier spacing values are applied, a reference signal is generated by using a sequence having a sequence length corresponding to a first ratio of a first subcarrier spacing set for transmission data to the maximum settable subcarrier spacing. The sequence of the reference signal is mapped to a frequency resource at mapping intervals in accordance with a second ratio which is the reciprocal of the first ratio, and the transmission data and the reference signal are transmitted.

Abstract: The present disclosure relates to a user equipment, UE, comprising the following. Processing circuitry determines, for a time slot group, one or more time slots to be monitored by the UE according to a monitoring function, operated by the UE for monitoring a downlink control channel in one or more monitoring occasions in one or more time slots for receiving downlink control information. The determining of monitoring time slots is performed in accordance with one or more of the following: a first criterion according to which a monitoring time slot includes a monitoring occasion associated with a common search space of the downlink control channel, a second criterion according to which a monitoring time slot includes a monitoring occasion associated with a UE-specific search space of the downlink control channel. Then, the processing circuitry monitors the downlink control channel in the determined monitoring time slots of the time slot group.

Abstract: The present disclosure relates to a user equipment (UE) and a scheduling node, as well as to the corresponding methods. In particular, a downlink control information (DCI) signaling carries a Transmission Configuration Indication (TCI) indicator specifying that two or more TCI states are configured and a frequency-domain resource assignment indicating frequency-domain resources allocated for the two or more TCI states. For each TCI state of the two or more TCI states, one or more regions in frequency domain is/are determined, each region having an integer multiple of a precoding resource block group (PRG), said integer being equal to or larger than 1, wherein regions of different TCI states do not overlap. The data are received or transmitted for each TCI state on the frequency-domain resources in the determined frequency-domain region.

Abstract: A communication apparatus includes circuitry and a transmitter. The circuitry generates a signal including one or more non-legacy long training field (LTF) symbols. Each of the one or more non-legacy LTF symbols has a plurality of data tones and a plurality of pilot tones. The circuitry maps a non-legacy LTF sequence to the plurality of data tones and the plurality of pilot tones, and groups the plurality of data tones with nonzero non-legacy LTF sequence values into a first tone group and a second tone group.
The signal includes information on a number Nsrs of space-time streams, wherein a total number of the one or more non-legacy LTF symbols is [NSTS/2] when the NSTS is 2, 3, 4, 7, 8, 11, 12, 15 or 16; and [NSTS/2] +1 when the NSTS is 5, 6, 9, 10, 13 or 14. The transmitter, in operation, transmits the generated signal.

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 to generate quantization values; and generating a bitstream including the quantization values. The three-dimensional points corresponding to the coefficient values belong to one layer among one or more layers. Each of a predetermined number of layers among the one or more layers is assigned a quantization parameter for the layer. In the quantizing, (i) when a quantization parameter is assigned to a layer to which each of the coefficient values belongs, the coefficient value is quantized using the quantization parameter, and (ii) when the quantization parameter is not assigned to a layer to which each of the coefficient values belongs, the coefficient value is quantized using a quantization parameter assigned to one layer among the predetermined number of the layers.
