摘要： A mobile communication system includes a plurality of RAT (Radio Access Technology) and can eliminate the need of a control channel for reporting RAT information. An LTE relay station has a cover area identical to a cover area owned by a WLAN host station and relays/transmits the signal received from an LTE base station to a mobile station in the cover area of the LTE relay station. The LTE relay station adds to the signal received from the LTE base station, one of the offsets: a frequency offset, a time offset, and a power offset as information indicating that the mobile station which receives a relay signal from the local station is located in the cover area of WLAN and transmits the signal after offset addition to the mobile station located in the cover area of the LTE relay station (i.e., the cover area of WLAN).

摘要： Provided is a wireless communication apparatus wherein channel estimation accuracy is improved while keeping the position of each bit in a frame, even when a modulation system having a large modulation multiple value is used for a data symbol. In the wireless communication apparatus (100), an encoding section (101) encodes and outputs transmitting data (bit string) to a bit converting section (102), and the bit converting section (102) converts at least one bit of a plurality of bits constituting a data symbol to be used for channel estimation, among the encoded bit strings, into ‘1’ or ‘0’ and outputs it to a modulating section (103). The modulating section (103) modulates the bit string inputted from the bit converting section (102) by using a single modulation mapper and a plurality of data symbols are generated.

摘要： A wireless communication device, e.g., a mobile station, capable of performing its communication and relay processing for another mobile station, when requested, at the same time without stopping the communication and the relay processing. In the device, an outgoing/incoming call request detection unit (106) detects an outgoing/incoming call request indicating that an outgoing call of the signal of the mobile station or an incoming call is requested from a signal inputted from an upper-layer processing unit (105). A relay request detection unit (108) detects a relay request signal indicating that an MS1 requests an MS2 for relay to a base station from a demodulated relay signal inputted from a relay signal demodulation unit (107). A communication rate determination unit (109) determines the communication rate so as to simultaneously transmit both the signal of the mobile station and the relay signal when a signal indicating that an outgoing/incoming call request is detected is inputted from the outgoing/incoming call request detection unit (106) or a signal indicating that a relay request signal is detected is inputted from the relay request detection unit (108).

摘要： In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, base station (100) sets a first resource candidate group, which enables terminal (200) capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal (300) incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Base station (100) selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.

摘要： A base station allowing mobile stations to efficiently remove interference signals. In this base station, an encoding part performs an error correction encoding of transport data to generate a bit sequence comprising systematic bits and parity bits; a repetition part repeats, as a repetition subject, only the parity bits out of the plurality of bits included in the bit sequence, which is generated by the encoding part, so as to perform a rate matching; a modulating part modulates, after the repetition, the bit sequence to generate symbols; an S/P part parallel converts the symbols serially inputted from the modulating part (103) and then outputs them to an IFFT part; and the IFFT part performs an IFFT processing of the symbols inputted from the S/P part and then maps them onto subcarriers in accordance with a predetermined mapping pattern, thereby generating OFDM symbols.
