摘要： An encoding method of generating an encoded sequence by performing encoding of a given encoding rate based on a predetermined parity check matrix. The predetermined matrix is either a first parity check matrix or a second parity check matrix. The first parity check matrix corresponds to a low density parity check (LDPC) convolutional code that uses a plurality of parity check polynomials, and the second parity check matrix is generated by performing at least one of row permutation and column permutation on the first parity check matrix. A parity check polynomial satisfying zero of the LDPC convolutional code is expressible by using a specific mathematical expression.

摘要： The image coding method can improve coding efficiency by using an adaptive bit-depth. The image coding method is used to code images to generate a coded stream. The image coding method includes: writing (S1001), into a sequence parameter set in the coded stream to be generated, a first parameter representing a first bit-depth that is a bit-depth of a reconstructed sample in the images; and writing (S1002), into the sequence parameter set, a second parameter which is different from the first parameter and represents a second bit-depth that is a bit-depth of an Intra Pulse Code Modulation (IPCM) sample in the images.

摘要： Disclosed are a wireless communication base station device, a wireless communication terminal device, and a wireless communication method with which the amount of signaling is reduced while maintaining a high scheduling gain. A judgment unit (117) stores in advance a correspondence between the number of code words and the number of clusters to reduce the maximum value for the number of clusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality that is output by an estimation unit (109), and the maximum value for the number of clusters that is output by the judgment unit (117), a scheduling unit (118) schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.

摘要： Provided is a terminal that is capable of avoiding a PHICH resource conflict where terminals having different UL-DL configurations coexist. When a response signal transmitted in a first sub-frame is in response to uplink data transmitted in a second sub-frame of a first configuration pattern, and a response signal transmitted in the first sub-frame is in response to uplink data transmitted in a third sub-frame of a second configuration pattern that is set on another terminal for which the configuration pattern setting cannot be changed, a first resource to be allocated to the response signal in the first sub-frame that is transmitted in response to the uplink data transmitted in the second sub-frame from the terminal; is different from a second resource to be allocated to the response signal in the third sub-frame that is transmitted in response to the uplink data transmitted from the another terminal.

摘要： When downlink data allocation is indicated in an ePDCCH, this terminal device can determine PUCCH resources to be used in notification of response signals indicating results of error detection of downlink data without imposing scheduling restrictions on future DL subframes. In this device, an extraction unit (204) receives downlink data on multiple unit bands. A CRC unit (211) detects errors in the downlink data. A response signal generation unit (212) generates a response signal by using the results of error detection of the downlink data obtained by the CRC unit (211). The control unit (208) arranges the response signal in the PUCCH resources corresponding to the current DL subframe.

摘要： An image decoding method of decoding, on a per-block basis, a coded image included in a bitstream, includes: performing arithmetic decoding on a current block to be decoded (S101); determining whether or not the current block is at the end of a slice(S103); determining, when it is determined that the current block is not at the end of the slice, whether or not the current block is at the end of a sub-stream which is a structural unit of the image that is different from the slice (S105); and performing arithmetic decoding on a sub-last bit and performing arithmetic decoding termination, when it is determined that the current block is at the end of the sub-stream (S106).
