Abstract: A communication device, system and method cooperate to transmit a signal from a base station, where the signal includes a current frame and a target frame. A counting unit counts a frame period and a reception control unit causes the receiving unit to transition to a sleep state. A reception control unit causes the receiving unit to return from the sleep state before a counting result of the counting unit reaches the target frame. The reception control unit also causes the receiving unit to return to the sleep state over a time period based on a difference between a current frame and the target frame.

Abstract: A user equipment includes radio communication unit that performs radio communication with a base station over a communication channel formed by aggregating a plurality of component carriers. The user equipment has a measurement unit that measures a channel quality of the communication channel, and a controller that creates a measurement report using a result of the measurement and sends the measurement report to the base station. Each data signal transmitted over the communication channel is classified into any of two or more classes depending on a QoS requirement thereof. The radio communication unit receives control information related to a mapping between each of the plurality of component carriers and the class of each data signal from the base station, and the controller controls at least one of the measurement and the sending of the measurement report, according to a procedure which varies depending on the control information. A base station performs associated functions, according to a communication method involving allocation of data to component carriers based at least in part on channel quality criteria for different data classifications.

Abstract: The disclosed invention determines whether a reception packet is an MM packet or a GF packet with precision and avoids unnecessary decoding operations performed at the GF- packet-reception time and inefficient communications . An OFDM symbol including 52 tones is transmitted when the MM packet is used, but an OFDM symbol including 56 tones is transmitted when the GF packet is used. Therefore, it is verified whether or not a signal exists in an FFT output at each of ±27 and 28 shown in a subcarrier index so that the format of the reception packet is determined. Otherwise, the packet format is determined on the basis of the Cyclic- Shift amount that changes for every format. When the GF packet is used, decoding processing performed in an L-SIG and afterward is stopped.

Abstract: By deciding positions of frequencies used via a relay station by a system in advance for assignment of boundary frequencies, frequencies of a central frequency more likely to be affected by the relay station are also mapped by avoiding a signal thereof. Alternatively, an adjacent cell whose central frequency is affected changes depending on a position of the relay station and thus, locations set to be highly likely to interfere with the central frequency of the adjacent cell is reduced by setting a region of the boundary frequencies permitted to the relay station in accordance with the position of the relay station.

Abstract: The disclosed invention enhances transmission efficiency by decreasing regions of reference signals which are attached to transmit packets from a transmitter during bidirectional SVD-MIMO communication. The transmitter transmits user data following a reference signal. At the other end, the receiver acquires a channel matrix, based on the reference signal attached preceding the user data, receives the user data, while weighting the data with receive weights derived from the channel matrix, adaptively estimates the channel matrix H as long as the user data is being received, and obtains transmit weights V' for transmitting user data in the reverse direction from an adaptively estimated channel matrix H'.

Abstract: A communication device and method provide a way for multiple transmitting base stations that share a same cell ID to transmit a predetermined signal to a user equipment that allows the user equipment to subsequently communicate with the most effective subset of said multiple transmitting base stations for that particular user equipment. The user equipment receives the predetermined signal from all of the base stations, and then provides feedback regarding the quality of signal reception. Based on the feedback, a message format is created that informs the user equipment which base stations are included in a subset of base stations that will be used to communicate with the user equipment.
