摘要： Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded.

摘要： In order to solve a problem of an accumulation on the transmission side, a delay on the reception side, and the like at the time of transmission in a communication system such as a wireless LAN system, each communication station in a network transmits a beacon in which information with respect to the network is written and sets a state in which a reception operation is performed during periods of time before and after the transmission of the beacon signal when performing access control not to make communication timing of a packet collide with that of another station by detecting a signal transmitted from another station. With performing such processing, a system can be formed based on minimum level of transmission and reception operation when transmission and reception data does not exist in each communication station in the network, and also a data transfer can be performed with latency as small as possible in a minimum necessary level of transmission and reception operation by making a transition of a transmission and reception state in accordance with a fluctuating volume of transmission and reception data.

摘要： The present invention eliminates a transmission-waiting operation which is unnecessary while accommodating a prioritized traffic. Although a communication station enters a transmission-disallowed state in response to detection of a signal addressed to another station in accordance with medium access control based on CSMA, if the communication station receives a frame transmitted with priority to a local station during the transmission waiting, it cancels the transmission-disallowed state, sends back a frame responding the frame transmitted with priority and effectively operates a transmission prioritized period. The communication station starts a search procedure to perform a processing of evading duplication of the transmission prioritized periods if it judges a possibility of a problem occurring in a time zone in which reception with priority is possible.
摘要翻译：本发明消除了在容纳优先业务量时不必要的传输等待操作。虽然响应于根据基于CSMA的媒体访问控制寻址到另一站的信号的检测，通信站进入传输不允许状态，但是如果通信站在传输等待期间接收到优先发送到本地站的帧，它取消传输不允许状态，发送一个响应优先发送的帧的帧，并有效地操作传输优先级周期。如果通信站判断在优先级可以接收的时间段内发生问题的可能性，则开始搜索过程来执行回避发送优先级周期的重复的处理。

摘要： A receiver for generating a transmission symbol stream by applying predetermined modulation processing to an encoded bit series obtained by encoding an information bit series having a predetermined transmission rate. The receiver generates a transmission-information bit series having a transmission rate lower than a predetermined transmission rate in accordance with an information bit series and receives a transmission signal generated in accordance with the transmission-information bit series through a communication channel. The receiver stepwise increases the low transmission rate of the transmission-information bit series to reach a predetermined transmission rate by stepwise increasing the low transmission rate, while stepwise increasing the number of communication channels to be used in accordance with the stepwise increase of the low transmission rate.
