摘要： A wireless communication method, a radio transmitter apparatus and a radio receiver apparatus wherein a signal sequence, which is used in a reception process using a first modulation scheme and can be generated from a signal sequence prepared for a reception process and used in a second modulation scheme, is employed, thereby achieving a performance to a similar extent to the reception process performance using the second modulation scheme. A radio transmitter apparatus (20) uses a first modulation scheme (e.g., OOK modulation scheme) to sequentially transmit, as a first sequence, both a sub-sequence a1(n), which is identical with a second sequence a(n) designed for use in a second modulation scheme (e.g., BPSK modulation scheme), and a sub-sequence a2(n), the bits of which are reverse to those of the second sequence a(n), in a time division manner. A radio receiver apparatus (30) detects the sub-sequence a1(n) and sub-sequence a2(n) in a received signal to send the detection result to the following stage for a signal processing.

摘要： Provided is a radio communication method which can reduce the power consumption as compared to the conventional technique while realizing coexistence of a plurality of radio communication methods and can perform synchronization with a super frame of other radio communication device. The super frame has life confirmation slots (2820, 2830) through which radio communication devices of various modulation types should transmit tone signals. A radio communication device has a chance to judge whether one or more radio communication devices using a different modulation type exist or no such device exists in the vicinity. If no such device exists, the slot to be used by the radio communication device of the modulation method is reported as a time that can be used by a radio communication group of other modulation method. Thus, by confirming existence of an object in the vicinity by other radio communication device with which communication cannot be performed, communication can be performed by sharing the super frame.

摘要： An adaptive beacon coordination method in a communication network using signal formats mutually incompatible. A coordination device broadcasts a first beacon in a first signal format and a second beacon in a second signal format in a superframe. The first and second beacons are used to send medium access information to a client device having the first signal format and a client device having the second signal format, respectively. When there are three or more signal formats in a network, the coordination device can broadcast three or more beacons. The number of beacons can be adapted to various superframes according to the functions of all the client devices in the network. If all the client devices support a signal format, the coordination device broadcasts only a single beacon in the signal format. After a predetermined number of superframes, the coordination device again starts to broadcast beacons so that new client devices having different respective signal formats can join the network.
摘要翻译：使用相互不兼容的信号格式的通信网络中的自适应信标协调方法。协调装置以超帧中的第一信号格式的第一信标和第二信号格式的第二信标广播。第一和第二信标用于分别向具有第一信号格式的客户端设备和具有第二信号格式的客户端设备发送媒体访问信息。当网络中有三种或更多种信号格式时，协调设备可以广播三个或更多个信标。根据网络中所有客户端设备的功能，信标数可以适应各种超帧。如果所有客户端设备都支持信号格式，则协调设备仅以信号格式广播单个信标。在预定数量的超帧之后，协调设备再次开始广播信标，使得具有不同相应信号格式的新客户端设备可以加入网络。

摘要： A receiving terminal is provided that prevents a load on a network near a receiving terminal from increasing when a retransmission request is made to a plurality of other terminals, and enables the probability of being able to compensate for a lost packet by means of a retransmission packet to be increased. In a receiving terminal that transmits a retransmission request for compensating for a lost packet lost in a network, a measurement section measures a time period corresponding to a distance in the network between the receiving terminal and a plurality of receiving terminals, a calculation section calculates for each of the receiving terminals a float (spare time period) found by subtracting the current time and a time period measured by the measurement section from a playback time at which a retransmitted packet is played back, and a decision section decides retransmission request transmission timing and a retransmission request transmission destination for each of the receiving terminals based on the calculated floats.
