摘要： According to aspects of the invention, a radio signal that constitutes a secondary use is provided with a predefined identifier (11) that identifies the radio signal as a secondary use. The identifier (11) can be any suitable signal characteristic that somehow can be detected by a suitable radio receiver. The identifier (11) enables identification of an origin of the radio signal. That is, whether it originates from a primary user or a secondary user. It therefore becomes possible to give all secondary users a more equal status, facilitating resource sharing. A transmitter is provided with an identifier inserter (25) for providing the identifier (11) in a transmitted radio signal. In a corresponding manner, a receiver is provided with identifier detector (29) for detecting a presence of the identifier in a received signal.

摘要： In a radio system where wireless nodes are in contact, the wireless nodes are enabled to exchange information, with adjacent nodes. In addition distant nodes out of range for direct communication can in accordance with one embodiment be communicated with by forwarding data over multiple hops. The wireless nodes are adapted to perform sensing of at least one radio resource in response to a request from a node. Based on the collective information from at least one other wireless nodes a wireless node can make an improved decision if a particular radio resource is free to use or not.

摘要： In a radio system where wireless nodes are in contact, the wireless nodes are enabled to exchange information with adjacent nodes. In addition, in one embodiment distant nodes out of range for direct communication can be communicated with by forwarding data over multiple hops. When a user, in particular a primary user, is detected by a node, a spectrum access blocking message is sent, to other nodes in the vicinity of the node thereby enabling blocking of the radio resource in a geographical area in which the other usage is detected. This means that the radio resource is blocked in that area from being accessed by other users than the primary user. The blocking message can be distributed in any suitable manner and can be tailored for the application at hand.

摘要： A method includes determining channel quality feedback information characterizing the channels statistically and calculating, based on the channel quality feedback information, a robustness related measure, such as outage capacity, associated with an on- frequency mode of operation and a robustness related measure, such as an outage capacity, associated with a frequency translated mode of operation. The method includes selecting the on-frequency mode of operation or the frequency translated mode of operation that maximizes the robustness related measure, such as outage capacity. The method also includes transmitting a message to other devices to operate in the selected on-frequency or a frequency translated modes. The method also includes performing maximum ratio combining or interference rejection combining, by at least one of the other devices, when the message indicates to operate in the frequency translated mode.

摘要： The present invention relates to methods and arrangements in a wireless communication system supporting cyclic-prefix insertion, using a symbol sequence comprising a number of samples for transmission over a radio channel that enables the handling of very large signal delay spreads. The symbol sequence is built up by a first symbol with CP and a second symbol with CP. The second symbol is a copy of the first symbol with the samples shifted in a way that makes the two adjacent symbols with CP match in regards to the sample order. The symbol sequence may also comprise a third symbol with CP or more, where the third symbol is a copy of the second symbol and with the samples shifted in analogy with the symbol shift described above. The resulting symbol sequence will thus appear as an extended continuous symbol thanks to the precise cyclic shift that matches adjacent symbols. This allows the receiver to place its FFT window anywhere during the extended symbol, e.g. at the end of the symbol sequence thus making it possible to handle a delay spread longer than the CP duration. It also allows to place e.g. two FFT windows and to combine the extracted signal into one SNR improved signal, while still handling a longer delay spread.
摘要翻译：本发明涉及一种支持循环前缀插入的无线通信系统中的方法和装置，其使用包括多个样本的符号序列，以在能够处理非常大的信号延迟扩展的无线电信道上进行传输。符号序列由具有CP的第一个符号和带有CP的第二个符号构成。第二个符号是第一个符号的副本，其中样本以使得具有CP的两个相邻符号与样本顺序匹配的方式移位。符号序列还可以包括具有CP或更多的第三符号，其中第三符号是第二符号的副本，并且样本类似于上述符号移位移位。因此，由于符合相邻符号的精确循环移位，所得到的符号序列因此将显示为扩展的连续符号。这允许接收机将其FFT窗口放置在扩展符号期间的任何地方。因此在符号序列结束时，可以处理长于CP持续时间的延迟扩展。它也允许放置例如。两个FFT窗口，并将提取的信号组合成一个SNR改进的信号，同时仍处理更长的延迟扩展。

摘要： Network coding may be performed with encoding and/or decoding that involves a multiplication operation. In an example embodiment, a communication node is adapted to perform multiplicative network coding. The communication node includes an encoder and a decoder. The encoder is arranged to perform an encoding operation by multiplying two or more signals that bear information to form a composite signal. The decoder is arranged to perform a decoding operation by multiplying a received composite signal with one or more complex-conjugated signals, with the decoder yielding a decoded signal that bears information. With the encoding operation, the communication node is adapted to at least partially perform multiplicative-network-coding encoding for a sending communication mode. With the decoding operation, the communication node is adapted to at least partially perform multiplicative-network-coding decoding for a receiving communication mode.
