摘要： Provided is a wireless communication system employing network coding which can set transmission quality for each destination of packets and improve throughput. The wireless communication system is provided with a wireless relay station apparatus and wireless terminal station apparatuses. The wireless relay station apparatus selects coding rates to be used for a first packet and a second packet in accordance with communication quality required for the first packet and the second packet, generates error correction encoded packets having the same data length from the first packet and the second packet using the selected coding rates, performs network encoding on the error correction encoded first and second packets to generate a network encoded packet, and transmits the generated network encoded packet. The wireless terminal station apparatus performs error correction encoding on a third packet equal to one of the first and second packets, performs network decoding on a received network encoded packet using the error correction encoded third packet to generate a decoded packet, and performs error correction decoding.

摘要： Provided is a wireless relay system that improves system throughput between terminal stations and flexibly makes system throughput variable with respect to short-term traffic fluctuations. In the wireless relay system, a plurality of relay stations relay communication between two terminal stations that perform random access. The terminal stations and the relay stations include a slot synchronization unit, a time synchronization unit, and a transmission unit. The slot synchronization unit synchronizes slot timing of a time slot indicating a unit time. The time synchronization unit performs time synchronization for synchronization of the slot timing. The transmission unit transmits a transmission packet to a wireless line in synchronization with the slot timing. A transmission right is allocated for at least one time slot to each of a plurality of groups which are configured so that a group of a terminal station or a relay station and a group of an adjacent terminal station or an adjacent relay station are different from each other. The transmission unit transmits the transmission packet to the wireless line only in a time slot in which the transmission right is allocated to the group to which the terminal station or the relay station belongs.

摘要： ATM provides quality classes that correspond to the amount of cell transfer delay allowed. In this invention, cells are classified according to quality class and stored in buffers. The cells are read starting from the buffer for the quality class with the highest priority, and successively proceeding to buffers for quality classes of lower priority. Alternatively, if there is room in the output interval of cells of a higher priority quality class, cells of a lower quality class are inserted among these cells. According to this invention, cell transfer that satisfies the quality requirement for cell transfer delay can be achieved using less hardware.
