    Abstract: Disclosed are a time-varying LDPC-CC encoding method and an encoder with high error correction capacity. The encoding method encodes into low density parity check convolutional codes (LDPC-CC) of time-varying period q using a parity check polynomial of encoding rate (n-1)/n (n an integer greater than or equal to 2), wherein the aforementioned time-varying period q is a prime number greater than 3. An information series is used as an input, and the information series is encoded using formula (1) as the parity check polynomial for solving the g-th (g=0, 1,..., q-1) 0. "%" means modulo, and each coefficient fulfills the following for k = 1, 2,..., n-1. "a

    Abstract: Provided is a terminal device that is capable of improving the characteristics of a response signal having poor transmission characteristics when ARQ is utilized in communication using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band and the terminal device is capable of providing a retransmission control method. In this device at the time of channel selection a control unit (208) selects a resource used in sending a response signal from among specific PUCCH resources notified in advance from a base station (100) and PUCCH resources mapped to a CCE and controls the transmission of the response signal. A response signal generating unit (212) supports implicit signaling with respect to any given response signal and at the same time as supporting LTE fallback from 2CC uses a mapping method that between bits smooths the number of PUCCH resources that can determine ACK/NACK simply by determining the PUCCH resource regarding which the response signal had notified.

    Abstract: Provided is a base station capable of performing cell search of all mobile stations having different communicable frequency band widths in a scalable band width communication system to which a multi-carrier communication method such as the OFDM method is applied. The base station includes: a modulation unit (102) for modulating SCH data after being encoded; a sub carrier setting unit (105) for setting one of the sub carriers to a sub carrier (SCH sub carrier) constituting the OFDM symbol for SCH data transmission; and an IFFT unit (106) for mapping the SCH data to the sub carrier set by the sub carrier setting unit (105) among the sub carriers and performing IFFT to generate an OFDM symbol. The sub carrier setting unit (105) sets one of the sub carriers which has a frequency of a common multiple between the sub carrier interval and the cell search interval as an SCH sub carrier.
