摘要： A base station, a mobile station and a retransmission control method for enabling communication to be more efficiently performed. In a communication system comprising a base station (100) and a mobile station (200), a time period required for the retransmission of a transport packet to complete is determined, and a retransmission control is performed, based on the required time period, to change the order of executing the retransmission of the transport packet and a handover. In this way, when it is estimated that the retransmission will complete soon, the retransmission is caused to complete in a handover source system, thereby avoiding waste of communication resources used in the preceding transmission and retransmission processes. When it is estimated that the retransmission will continue for a while, the communication resources used in the preceding transmission and retransmission processes are wasted, but a more appropriate MCS can be assigned, in a handover destination system, so as to perform a retransmission, thereby enabling communication to be efficiently performed.

摘要： Provided are a communication system and a base station capable of preventing interference between signals and improving the throughput. A base station device (100) includes: a user quantity monitoring unit (130) for monitoring the number of terminals (users) existing in a cell of the local device; a RACH control unit (140) for transmitting control information (frame type identifier) controlling the frame type of RACH corresponding to the number of terminals; and an RF transmission unit (165) for transmitting the control information to the terminals. The RACH control unit (140) performs control in such a way that as the number of terminals increases, the control information amount contained in the frame of the frame type corresponding to the number decreases. Thus, in accordance with the number of users, the control information data amount is reduced and it is possible to transmit a short frame. Even if the number of users increase, it is possible to reduce the possibility of frame conflict in the RACH, thereby improving the throughput.

摘要： The invention includes methods for achieving efficient channel access in a wireless communications system. The invention is embodied in a wireless network adapter that is present in all stations belonging to the network. The invention describes methods by which access overheads may be reduced by introducing the concept of context sensitive frame timing—using which stations redefine and interpret frame timing depending on context and signaling. The result of realizing the invention is an improvement in medium utilization efficiency and consequently, an overall improvement in network throughput.

摘要： A communication terminal apparatus capable of suppressing communication delay independently of the packet size, efficiently performing communication, and further solving the problem of hidden terminals. In this apparatus, a number-of-STAs holding part (107) counts, based on a received signal inputted from an STA determining part (105), the other STAs in the same cell. A back-off establishing part (108), which stores a table or a back-off value calculation formula in accordance with the number of the STAs in the cell, uses the number of the STAs in the information about the number of registered terminals in the cell to select or calculate the corresponding back-off value, thereby establishing the back-off value. A packet generating part (109) generates a packet including both number-of-terminals information and transport data. A transmission standby part (112) establishes a transmission standby time such that only the back-off value is on transmission-standby. The transmission standby part (112) then causes the packet to be on transmission-standby by the established transmission standby time and be outputted after a lapse of the transmission standby time.

摘要： An interleave apparatus and an interleave method for preventing an increase in the number of retransmissions to improve the throughput. In a wireless communication apparatus having the interleave apparatus, a data holding part (1021) two-dimensionally arranges and holds bit sequences. A first index calculating part (1022) sequentially calculates first indexes to be used for reading, in a column direction, the bit sequences arranged in a row direction. A second index calculating part (1023) sequentially calculates second indexes to be used for reversing the order of the upper-order and lower-order bits to be read from the even-numbered columns when the bit sequences are read in accordance with the first indexes. A third index calculating part (1024) sequentially calculates third indexes to be used for reading the bit sequences from a different start position in accordance with the number of retransmissions. A reading part (1025) reads the bit sequences in the order that is in accordance with the third indexes. A mapping part (103) maps the read bit sequences to the respectively corresponding subcarriers.
