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.

In addition, distant nodes out of range for direct communication can be communicated with by forwarding data over multiple hops. The wireless nodes are configured to perform sensing of at least one radio resource. A node can be adapted to combine the sensing measurement data into a sensing result, such as an estimate of the probability of whether the resource is free or not. The sensing performed in a node is distributed to at least one other wireless node. Each wireless node can, therefore, access sensing information from at least one other wireless node located in the vicinity of the wireless node. Based on the collective information from at least one other node, 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： Improved amplify-and-forward relaying in a communication network is described, including an example network of multiple single-antenna mobile stations, a multi-antenna relay station, and a multi-antenna base station. Bi-directional communication with improved transmission efficiency is enabled by suitable transmit/receive processing at the relay station without drawbacks of current relaying techniques. Linear transmit and receive processing matrices are disclosed, and it is shown that the numbers of antennas at the relay station and the base station can be substantially the same without reducing network capacity, closely matching the performance for low and high signal to noise ratios of current techniques that require the relay station to have twice as many antennas as the base station.

摘要： A distributed antenna system based wireless cellular communication system with transmit side linear interference cancellation is described. In this system the effective channel elements (I) and (II) are estimated and reported by mobile station MS1 and MS2, respectively, to a transmit weight matrix processing apparatus. Processing apparatus uses the effective complex channel matrix (one row reported by each mobile station) to differentially update the transmit weight matrix used for the transmit side linear interference cancellation.
