摘要:
A wireless relay device that transmits a reception signal from a transmission device to a reception device includes a determination section configured to determine whether or not the reception signal is a retransmission signal retransmitted from the transmission device, and an amplification section configured to amplify the reception signal when the determination section determines that the reception signal is the retransmission signal, and not to amplify the reception signal when the determination section determines that the reception signal is not the retransmission signal.

摘要:
A wireless communication apparatus that transmits a wireless signal, the wireless communication apparatus including a dividing unit that divides data transmitted in a data area of a frame format of the wireless signal into a plurality of segments. The wireless communication apparatus includes an encoding unit that encodes the data segmented by the dividing unit segment by segment.
摘要:
A communication apparatus for communicating via a frame containing a plurality of first type blocks into which pilot information is inserted and a plurality of second type blocks into which control information or data is inserted, the communication apparatus including a channel estimation accuracy predicting unit for predicting channel estimation accuracy of each of the plurality of second type blocks based on channel estimate values of the plurality of first type blocks in the frame. The communication apparatus includes an allocation determining unit for determining an allocation based on priority information containing a priority of each type of the control information and data such that control information or data of a higher-priority type is inserted into a block among the plurality of second type blocks with higher channel estimation accuracy.
摘要:
A base transceiver station performing communications with user equipment, includes a receiving unit to receive an uplink transmission signal containing a propagation path fluctuation value between a self-device and the user equipment from the user equipment; and a communication permitting unit to control a period of time during which a permission of communications is given to the user equipment based on the propagation path fluctuation value.
摘要:
A wireless device transmits first information, representing whether the wireless device expects to receive data from a base station, to the base station before receipt of an inquiry from the base station about whether the wireless device expects to receive the data, and on receipt of the inquiry from the base station, restricts transmission of a response to the inquiry to the base station if the first information is not changed.
摘要:
According to priorities determined on the basis of a number of pieces of battery information which concern batteries of a number of communication terminals and each of which is received from the communication terminals, data communication with communication terminals are controlled. The priorities are varied, irrespective of a variation in the pieces of battery information, according to a rule predetermined.
摘要:
In a base station apparatus, signal processing units are connected to a corresponding antenna unit and another antenna unit, a part of resources for processing a signal received by the antenna unit corresponding to each signal processing unit is allocated to processing of a signal received by the other antenna unit, and the signals received by the corresponding antenna unit and the other antenna unit are subjected to multi-antenna reception processing using the resources.
摘要:
A communications apparatus accommodated in a communications system for exchange of information between a communications apparatuses by a multicarrier transmission mode using a plurality of subcarriers. The communications apparatus includes a dedicated transmission data generator for each communications apparatus, configured to generate frequency band information indicating which frequency band is to be used for transmission of data information between each communications apparatus; and a transmitter configured to transmit the dedicated frequency band information with dedicated control channel for each communications apparatus by using a specific frequency band which is set from among a plurality of frequency bands assigned to the communications system, in which the specific frequency band is set as a primary band in a frequency band assigned to the communication system.
