摘要： The transmission of a reference signal, such as a CSI-RS, is enabled while maintaining a power saving effect when performing inter-cell cooperative transmission/reception or the like in a plurality of cells. In order to realize inter-cell cooperative transmission/reception, a CSI-RS which is used for estimating the state of a spatial propagation path of a communication line is generated by a CSI-RS generation unit, and the CSI-RS is disposed in a predetermined subframe by a disposition unit and transmitted. At this time, when a frame has ten subframes #0 to 49, the CSI-RS is disposed in the subframes #4 and #9, which are subframes excluding the subframes #0 and #5 incapable of transmitting a CSI-RS and are subframes other than subframes capable of acting as MBSFN subframes when discontinuous communication (Extended Cell DTX) is performed so as to achieve power saving, and transmitted.

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. The coding section 13 subjects data sequences that pair up with each other to XOR processing and outputs a processing result to a modulation section 14.

摘要： A radio communication apparatus, a radio communication method, and a radio communication system, which are capable of improving receiving reliability of predetermined bits such as bits having a high degree of importance, and the like, are provided. A code length L is decided based on the modulation system and the coding rate being specified, and the bit length of S2. The relay station decides a coding rate of S1 from the code length L. In the case of 16 QAM, since a half of all bits correspond to the bits used as the object of the quadrant discrimination, the bit length of S1 is set to L/2. Therefore, the coding rate of S1 is 2(LS1)/L, where the bit length of S1 is LS1. In the present example, S1 is coded and gives S1+P1, and S2 is coded and gives S2+P4. P1 denotes the parity bit of S1, and P4 denotes the parity bit of S2. The relay station changes the bit arrangement such that all bits of the code word (S1+P1) of S1 come to the position of the quadrant discrimination in the constellation of 16 QAM respectively.
摘要翻译：提供能够提高诸如具有高度重要度的位的预定位的接收可靠性的无线电通信装置，无线电通信方法和无线电通信系统等。代码长度L是根据调制方式和指定的编码率，S2的位长决定的。中继站从码长L确定S1的编码率。在16QAM的情况下，由于所有比特的一半对应于用作象限鉴别的对象的比特，所以将S1的比特长度设置为L / 2。因此，S1的编码率为2（LS1）/ L，S1的位长为LS1。在本示例中，S1被编码并给出S1 + P1，S2被编码并给出S2 + P4。 P1表示S1的奇偶校验位，P4表示S2的奇偶校验位。中继站改变比特布置，使得S1的码字（S1 + P1）的所有比特分别到达16QAM的星座图中的象限鉴别的位置。

摘要： Provided are a radio transmission device and a radio transmission method which can reduce the transmission packet collision generation ratio even when no resource allocation signal is detected in retransmission. When control information outputted from a decoding unit (204) contains NACK and retransmission Grant, a retransmission resource check unit (205) determines that the resource indicated by the retransmission Grant is the retransmission resource. Moreover, when no retransmission Grant is detected and the initial transmission is a wideband transmission, the retransmission resource check unit (205) determines that no retransmission resource exists and instructs an RB allocation unit (209) to stop retransmission. Moreover, when no retransmission Grant is detected and the initial transmission is a narrow band transmission, a predetermined resource is determined to be the retransmission resource.

摘要： There are provided a wireless communication apparatus, a wireless communication method, and a wireless communication system capable of selectively utilizing the advantages of both centralized control and distributed control while a time needed for cell searching is suppressed. FIG. 4(a) represents an example in which a P-BCH and an S-SCH for the centralized control and a P-BCH and an S-SCH for the distributed control are frequency-divided, and the P-BCH and the S-SCH for the distributed control are transmitted to a distributed control resource. FIG. 4(b) represents an example in which a P-BCH and an S-SCH for the centralized control and a P-BCH and an S-SCH for the distributed control are time-divided, and the P-BCH and the S-SCH for the distributed control are transmitted to a centralized control resource. Since a relay station transmits the P-SCH as a centralized control resource, a mobile station can specify sub-frame timing by using only the centralized control resource.
