摘要： A network node (110) and a method therein for managing radio, resources are disclosed. The radio resources are dedicated for beacon (121, 122) signaling, fey a first device; (131) and a second device (132), in conjunction with device-to-device, “D2D”, discovery. The first device: (131) is stationary and the second device (132) is non-stationary. The network node (110) selects (202) a first and a second set of radio resources out of the radio resources. The first and second sets are dedicated for beacon signaling by the first device (131) and the second device (132), respectively. The first set of radio resources Is non-overlapping with the second set of radio resources. Then the network node (110) schedules (203) a specific radio resource of the first set of radio resources to the first device (131). Next, the network node (110) sends (204) information about the scheduled specific radio resource to the first device (131). The network node (110) further sends (205) information about the second set of radio resources to the second device (132). In this manner, the second device (132) restricts Us radio resources usable for beacon signaling to the second set of radio resources.

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： 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 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： Wireless nodes for use in a radio system are provided. A wireless node for use in a radio system may include a transmit and receive unit configured to request sensing information of at least one radio resource from at least one other wireless node of the radio system, and to receive the sensing information of the at least one radio resource from the at least one other wireless node of the radio system.

摘要： The present invention relates to the technical field of dynamic spectrum access. Synchronization of quiet periods for spectrum sensing can significantly benefit sharing of available secondary access spectrum between two or more wireless communication systems in the same geographic region. The object of the present invention is to provide a methodology by which quiet periods can be synchronized in time between different secondary access wireless communication systems. Quiet Period Clients (QPC) of secondary access wireless communication systems are adapted to send requests to a Quiet Period Server (QPS) to obtain a quiet period rule set. The QPC receives from the QPS an answer specifying the quiet period rule set, and optional quiet period synchronization information. The systems perform their transmissions in accordance with the received rules.
