A control device includes reception circuitry which, in operation, receives control information regarding resources to be allocated to a plurality of distributed units, and control circuitry which, in operation, determines, based on the control information, a distributed unit to which a received signal of uplink is to be transferred among the plurality of distributed units.

Control device and control method

A base station able to maintain backward compatibility with an LTE mobile station while minimizing the amount of increase in uplink scheduling information reception and demodulation/decoding processing in independent uplink/downlink cell data transmission. A wireless communication system includes a cell #, a cell #, and an LTE-A mobile station, and supports independent uplink/downlink cell data transmission. The base station of the cell #arranges a PDCCH+, which includes uplink scheduling information from the LTE-A mobile station to the base station of the cell #, in a downlink data region in the downlink connection of the base station of the cell #

Base station apparatus, mobile station apparatus, and transmission method

A low-density parity check convolution code (LDPC-CC) is made, and a signal sequence is sent after being subjected to an error-correcting encodement using the low-density parity check convolution code. In this case, a low-density parity check code of a time-variant period (3g) is created by linear operations of first to 3g-th (letter g designates a positive integer) parity check polynomials and input data.

Transmission method, transmission apparatus, reception method and reception apparatus

A transmission apparatus includes an encoder that codes a data sequence with a parity check matrix, wherein the data sequence includes a final information bit sequence and virtual information bits, and outputs the final information bit sequence and a parity sequence, as LDPC codes, and a transmitter that transmits the LDPC codes as a transmission data. A column length of the parity check matrix is longer than a total length of the final information bit sequence and the parity sequence, by a length of the virtual information bits that are set to '0' and are not transmitted. The total length of the final information bit sequence and the parity sequence has a sequence length corresponding to a length from a first column to a determined column of the parity check matrix. The encoder generates the LDPC codes by using the first column to the determined column among one or more column(s) of the parity check matrix.

Transmission apparatus and associated method of encoded data

This invention describes a method to enable simultaneous connections to multiple cellular networks while utilising only a single subscriber identity by assigning a unique mobile equipment identity to each radio connection and an apparatus to enable simultaneous connections to multiple cellular networks while utilising only a single subscriber identity by assigning a unique mobile equipment identity to each radio connection where the user equipment is able to manage the multiple International Mobile Equipment Identifiers assigned by the manufacturer of the mobile device by correctly identifying the connected interface and reporting the correct accompanying mobile equipment identifier.

Communication apparatus and communication method

A base station able to maintain backward compatibility with an LTE mobile station while minimizing the amount of increase in uplink scheduling information reception and demodulation/decoding processing in independent uplink/downlink cell data transmission. A wireless communication system includes a cell #1, a cell #2, and an LTE-A mobile station, and supports independent uplink/downlink cell data transmission. The base station of the cell #2 arranges a PDCCH+, which includes uplink scheduling information from the LTE-A mobile station to the base station of the cell #2, in a downlink data region in the downlink connection of the base station of the cell #1.

Reception apparatus and associated method of receiving encoded data

Transmission apparatus and associated method of encoding transmission data

In order to shorten the time in which an initial connection is established when switching directivity and then performing the initial connection, a frame timing control unit sets, until detection of an RACH signal, a transmission timing of a transmission frame for transmitting a search signal and a broadcast signal and also sets a reception-start timing for starting the reception of the corresponding RACH signal. A search/broadcast signal generation unit generates the broadcast signal and the search signal including reception-timing information. A beam directivity control unit sets, for a predetermined time starting from the reception-start timing, a directivity pattern such that the directivity is in the same direction as the directivity pattern for the corresponding transmission-timing information, whereby the beam directivity control unit controls a beam directivity operation unit.
