摘要： A transmitting apparatus and a transmitting method wherein the systematic bit reception quality can be improved and the throughput performance can be improved. An IR parameter control part (101) controls, based on the number of retransmissions, the ratio of systematic bits to parity bits in mapping them to packets, and controls to map a parity bit to an initially transmitted packet, while mapping a systematic bit to a retransmitted packet. An encoding part (102) generates the systematic bits and parity bits and maps them to the packets in accordance with the IR parameters. A transmission power calculating part (105) calculates, based on reception quality information of the initially transmitted packet fed back from a receiving end, the transmission power of the transmitted packet to which the systematic bit is mapped. A transmission power control part (106) controls the transmission power of the retransmitted packet such that it is equal to the transmission power as calculated by the transmission power calculating part (105).

摘要： Provided are a radio transmission device and a radio transmission method, which prevent the deterioration of a preamble detecting performance while reducing the collision probability of a RACH. In this radio transmission device, a Signature table storage unit (103) divides the magnitudes of transmission loss levels into individual levels corresponding to the distances from a base station, to cause CAZAC series and circulation shift quantities to correspond to each other at the individual levels, and is provided with a table containing a plurality of Signatures created from the CAZAC series and the circulation shift quantities caused to correspond to each other. A Signature selecting unit (104) selects one of the corresponding Signatures at random from the Signature table storage unit (103), on the basis of the magnitude of the transmission loss level outputted from a transmission loss level deciding unit (102). A RACH signal generating unit (105) generates the RACH signal with the Signature selected.

摘要： There are provided a wireless transmitting apparatus and a wireless transmission method that enable reduction of transmission delay of a system by enhancing receiving performance achieved during transmission of network-coded data. A decoding section 18 subjects a demodulated signal to error correction decoding and outputs the decoded signal to a buffer 17. The buffer 17 holds a data packet for a given period of time and outputs the packet to an encoding section 12. An encoding control section 11 controls an encoding rate for transmission data and outputs control information to the encoding section 12. In accordance with control information from the encoding control section 11, the encoding section 12 subjects a data packet to error correction encoding and outputs the coded data packet to a coding section 13.

摘要： Even when a CPU gains higher performance and a distributed computing environment is being put in place, it is not easy to follow the speed of hardware image processing implemented by dedicated hardware. Hence, jobs of filter processing having a heavy operation load and low distributability are selectively and intensively input to a small number of resources having performance as high as possible. On the other hand, since the color conversion processing and gamma processing have high distributability, even when jobs are input to many resources having low performance, an improvement of the processing speed can be expected. Therefor, color conversion processing and gamma processing distribute jobs to many resources.

摘要翻译： 即使CPU获得更高的性能并且分布式计算环境正在建立中，也不容易遵循由专用硬件实现的硬件图像处理的速度。 因此，具有重的操作负载和低分配性的过滤处理的作业被选择性地和集中地输入到具有尽可能高的性能的少数资源。 另一方面，由于颜色转换处理和伽马处理具有高分配性，因此即使作业被输入到具有低性能的许多资源中，也可以期待处理速度的提高。 因此，颜色转换处理和伽马处理将作业分配给许多资源。

摘要： A radio transmitting apparatus and a radio transmitting method wherein the throughput is improved and a fast initial access processing including an RA burst is accomplished. According to these apparatus and method, a signature table storing part (101) has a plurality of signature groups generated from a plurality of different Zadoff-Chu sequences with a set of signatures generated from one Zadoff-Chu sequence being one signature group. A signature sequence assignment control part (102) switches signature groups to be assigned to a UE for each of paging transmissions, thereby assigning a signature sequence, which is to be used for an initial RA, from the same signature group.

摘要： Disclosed are a sequence report method and a sequence report device for reducing a signaling amount for reporting a Zadoff-Chu sequence or a GCL sequence allocated for a cell. Indexes starting at 1 are correlated to different ZC sequences and are allocated for cells so that the indexes are continuous. When such ZC sequences are reported from BS to UE, a start index indicating the start of the continuous indexes is combined with the number of allocated sequences and they are reported as allocation sequence information by a report channel. The UE and the BS share the correlation between the ZC sequences and the indexes and the UE identifies a usable sequence number according to the correlation and the allocation sequence information reported from the BS.
