摘要： A communication system includes a first communication device that transmits transmission data containing user data and control data, and a second communication device that receives the transmission data from the first communication device. The second communication device includes a temporary storing unit that temporarily stores therein the received transmission data, and a space-insufficient-information transmitting unit that transmits, when an amount of the transmission data stored in the temporary storing unit exceeds a first threshold, space insufficient information indicating that available storage space of the temporary storing unit is insufficient to the first communication device. The first communication device includes a transmission control unit that transmits, when receiving the space insufficient information from the second communication device, transmission data excluding the user data from the transmission data to the second communication device, and that resumes, when receiving space-insufficient dissolution information from the second communication device, transmission of the user data.

摘要： A radio environment acquirer acquires a radio environment condition of radio communication with a subordinate mobile station. A transmitter transmits, to the mobile station, information notifying a signal which is selected from among multiple signal groups and which is to be transmitted in a transmission area of a random access signal, and a notification of a period over which transmission of the signal as the random access signal is permitted. The period is variable in accordance with the radio environment condition acquired by the radio environment acquirer.

摘要： A transmitting device for transmitting data by means of wireless signals to at least one of a plurality of receiving devices via a channel shared by the plurality of receiving devices is provided. The transmitting device receives reception quality data from each of the plurality of receiving devices; determines future predicted values relating to the reception quality of the respective receiving devices on the basis of the one or plurality of sets of past reception quality data; and selects receiving devices and assigns transmission data to be transmitted to the selected receiving devices to the channel on the basis of the future predicted values. The rate of generation of reception data errors on the side of the receiving devices and data re-transmission rate due to data errors can be reduced, and the throughput can be improved.

摘要： In the event of detecting first information used for first random access and second information used for second random access, the second information being received from the base station unit, a wireless terminal selects one between the first information and the second information. Thereby, either one of the random accesses can be selectively performed, efficiently using resources such as signatures used for random access.
