摘要： The present invention provides a wireless communication system and a terminal. A base station includes means that notifies terminals of an intensity of a received interference power. The terminal includes means that controls a transmission power for transmitting data to the base station, which is one of base stations and to which data is to be transmitted, by referencing an intensity of interference power (OSI) notified from base stations to which data is not to be transmitted. The means that controls a transmission power calculates a decision value for increasing/decreasing the transmission power, wherein the decision value is variable according to the current transmission power of the terminal and propagation attenuations between the terminal and the base stations to which data is not to be transmitted, and variably controls the amount of transmission power increase/decrease according to the decision value for increasing/decreasing a transmission power.

摘要： A wireless access terminal, after handoff, adds channel quality information calculated in the wireless access terminal to a header of transmit data and transmits this data until a wireless base station succeeds in receiving at least one or more packets. The wireless base station, when having succeeded in receiving a packet for the first time after the handoff, extracts the channel quality information from a received header to initialize channel quality information inside the wireless base station. Subsequently, the wireless base station autonomously updates the channel quality information in response to success or failure of packet reception and controls the transmission rate.

摘要： Since the OFDM communication method does not select whether plural sectors use a same terminal as a transmission destination, or always use it as a transmission destination, giving a preference to system throughput deteriorates channel quality of a terminal in a sector boundary, while increasing channel quality in sector boundaries greatly deteriorates system throughput. In a base station, when a sector transmits to a terminal in the front of a beam, only the sector performs the transmission, and when transmission is made to a terminal in a sector boundary off the direction of the beam, a different sector transmits to the same terminal using a same hopping pattern. Thereby, tradeoff between the channel quality of the terminal in a sector boundary and deterioration in system throughput can be minimized.

摘要： A radio base station, a radio communication terminal, and a radio communication system that can efficiently utilize broadband resources even if many packets of different sizes and different QoS requirements are mixed when sent and received. When a data transmission request is sent from a radio terminal to a base station, at least one of a data transmission duration time, a transmission data transmission interval, and an expiration time is included in the data transmission request. The base station receives data transmission requests from multiple radio terminals, schedules the data transmission requests from multiple radio terminals, assigns bandwidths to the multiple radio terminals based on the duration time, transmission interval, and expiration time included in each of the data transmission requests and continues the assignment of bandwidths to the radio terminals during the duration time based on the received duration time.
