Abstract

The disclosure relates to a user equipment (UE), a scheduling device, and respective methods for a UE and a scheduling device. The UE comprises a transceiver and circuitry. The circuitry detects, while in a procedure for transmitting, in an inactive state, first data for a first logical channel, that second data for a second logical channel are to be transmitted in the inactive state. More specifically, the procedure for transmitting the first data is a configured grant (CG), procedure for transmitting the first data, and the second logical channel is (i) not configured with CG resources for transmissions in the inactive state, and (ii) configured with random access (RA) resources for transmissions in the inactive state. The circuitry determines whether or not there is a transmission opportunity to wait for. The transmission opportunity to wait for is i) a transmission opportunity for transmitting at least part of the first data, and ii) expected to occur as part of the procedure for transmitting the first data. When it is determined that there is no transmission opportunity to wait for or the transmission opportunity to wait for is no longer expected to occur, the circuitry initiates a RA procedure for transmitting the second data using the RA resources. When, on the other hand, it is determined that there is the transmission opportunity to wait for and said transmission opportunity occurs, the circuitry controls the transceiver to transmit, using said transmission opportunity, a traffic indication indicating the detection of the second data.

A three-dimensional data encoding method that is for encoding a three-dimensional point that has attribute information. The three-dimensional data encoding method involves calculating a prediction value for the attribute information of the three-dimensional point (S3061), calculating a prediction residual that is the differences between the prediction value and the attribute information of the three-dimensional point (S3062), generating binary data by binarizing the prediction residual (S3063), and arithmetically encoding the binary data (S3064). The arithmetic encoding may, for example, use a different encoding table for each bit of the binary data.

Abstract

An encoder partitions into blocks using a set of block partition modes obtained by combining one or more block partition modes defining a partition type. The set of block partition modes includes a first partition mode defining the partition direction and number of partitions for partitioning a first block, and a second block partition mode defining the partition direction and number of partitions for partitioning a second block which is one of blocks obtained after the first block is partitioned. When the number of partitions of the first block partition mode is three, the second block is a center block among the blocks obtained after partitioning the first block, and the partition direction of the second block partition mode is same as the partition direction of the first block partition mode, the second block partition mode includes only a block partition mode indicating that the number of partitions is three.

Abstract

By the present invention, the number of encoding bits allocated to encoding of extended-band spectrum is reduced while degradation of sound quality in the extended band is suppressed. A band compression unit (105) creates combinations of sub- band spectra in pairs of two samples each in order from a low-range side in a band compression target sub-band, selects a spectrum having a large absolute-value amplitude among the combinations, and arranges the selected spectrum close to the low-range side on a frequency axis. A number-of-units recalculation unit (106) redistributes bits saved in the sub-band for which band compression was performed to a low range outside the extended band, and redistributes the number of units on the basis of the redistributed bits.

Abstract

A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part (104) extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part (102). A GI extracting part (107) extracts, from the signal subjected to the radio reception process by the received RF part (102), GI having a length determined by an extracted GI length deciding part (106). The extracted GI is adjusted by a data position adjusting part (108) such that its rear end coincides with the read end of the extracted data portion. A combining part (109) combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part (110), which equalizes the signal distortions of the combined signal on the frequency axis.

Abstract

In the conventional art inventions for coding multi-channel audio signals, three of the major processes involved are: generation of a reverberation signal using an all-pass filter; segmentation of a signal in the time and frequency domains for the purpose of level adjustment; and mixing of a coded binaural signal with an original signal coded up to a fixed crossover frequency. These processes pose the problems mentioned in the present invention. The present invention proposes the following three embodiments: to control the extent of reverberations by dynamically adjusting all-pass filter coefficients with the inter-channel coherence cues; to segment a signal in the time domain finely in the lower frequency region and coarsely in the higher frequency region; and to control a crossover frequency used for mixing based on a bit rate, and if the original signal is coarsely quantized, to mix a downmix signal with an original signal in proportions determined by an inter-channel coherence cue.
