摘要： A radio communication system having an interference reduction function and enabling random access is constructed without complicating a terminal structure. A base station has an interference signal detection function, performs interference signal detection intermittently and transmits a beacon signal when no interference signal is detected. A terminal starts up from a sleep mode before transmitting data, performs reception waiting, transmits data only immediately after reception of the beacon signal, transits to the sleep mode again if the beacon signal is not received and repeats the abovementioned sequence after a predetermined time elapses.
摘要翻译：具有干扰消除功能和实现随机接入的无线电通信系统被构建而不使终端结构复杂化。基站具有干扰信号检测功能，间歇地进行干扰信号检测，并且当没有检测到干扰信号时发送信标信号。在发送数据之前，终端从睡眠模式启动，执行接收等待，在接收到信标信号之后立即发送数据，如果没有接收到信标信号，则再次进入休眠模式，并且经过预定时间后重复上述序列。

摘要： In a wireless network system, the nodes share a frequency hopping pattern. A method comprises providing a channel list table which includes, for each transmitting node, one or more channel lists, each channel list containing conditions of the channels of the shared frequency hopping pattern that include at least one available channel for communications with a target node; selecting a channel of a next allocated time slot from the shared frequency hopping pattern at the transmitting node; selecting the channel list for the target node from the channel list table, to which the transmitting node transmits; checking if the selected channel is available based on the selected channel list; setting the selected channel at the transmitting node if the selected channel is available; and calculating a substitute channel from the channel list if the selected channel is not available.

摘要： Systems and methods directed towards improving reliability for wireless networks. Selective polling techniques are utilized to selectively poll stations within a wireless network in order to ensure that a station failing to properly transmit data is given an opportunity to rectify the transmission failure. The selective polling techniques can be applied to any polling-based system, thus maintaining backwards compatibility with legacy systems.
