摘要： The present invention relates to a method and fixed communication node that allow for interference reduction in a wireless communication system operating in TDD mode. Interference channel information on a number of interference channels (19) between a fixed communication node (10,11) and a number of other fixed communication nodes (10, 11) is stored. The interference channel information may e.g. include information on directions to the other fixed communication nodes or channel estimates derived from measurements which may have been made at times of low system load. Interference reduction between the fixed communication node and a set of the other fixed communication nodes is performed by antenna weight selection for a plurality of antenna elements of the fixed communication node, wherein the antenna weight selection is based on the stored interference channel information relating to the set of the other fixed communication nodes.

摘要： A method in a network node for allocating to user equipments a respective carrier is provided. The carrier is a frequency carrier for wireless communication. The network node is comprised in a cellular network. The network node identifies (202) a set of carriers. The carriers in the set of carriers each are associated with a respective geographic handover region for handover between cells. The geographic handover regions of the carriers differ from each other more than a threshold. When the network node has identified (203) a group of user group of user equipments with correlated mobility pattern, it allocates (204) to at least two of the user equipments within the group of user equipments a respective carrier. The allocation is performed such that the at least two user equipments in the group are spread among the carriers in the set of carriers.

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 adapted to perform sensing of at least one radio resource. In accordance with one embodiment a node can be adapted to combine the sensing measurement data into a sensing result, such as (but not limited to) 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 and in particular to a multitude of wireless nodes. Each wireless node can therefore access sensing information from at least one other wireless nodes located in the vicinity of the wireless node. Based on the collective information from at least one other node and in particular a multitude of wireless nodes a wireless node can make an improved decision if a particular radio resource is free to use or not.

摘要： The invention presents methods and corresponding devices for improving cooperative spectrum sensing. A device (61;61.1) first receives an invitation (17;35) to participate in cooperative spectrum sensing. The device performs an autonomous decision (19) on whether or not to participate in the cooperative spectrum sensing in response to the invitation. If it is determined to participate in the cooperative spectrum sensing to which the invitation relates, spectrum sensing is then performed (21;45). With the invention, sensor selection becomes "distributed", i.e. it is up to the device itself to decide on participation in the cooperative sensing, rather than having, for example, a central entity determining what devices should act as sensors in the cooperative spectrum sensing. One advantage is that the amount of signalling required for sensor selection can be kept at a minimum, thereby saving communication resources.

摘要： The present disclosure relates to a method of a first radio device (401; 402) using a first radio access technology, RAT, (405) for communication with a second radio device (401; 402). The method comprises listening for any transmission in a frequency channel of an unlicensed radio frequency band. The method also comprises determining whether the channel is idle. The method also comprises transmitting a first radio message on the channel in accordance with a second RAT (406), different than the first RAT (405). The method also comprises determining transmission properties for a message to be transmitted on the channel in accordance with the first RAT, based on the determining of whether the channel is idle. The method also comprises transmitting a second radio message on the channel, to the second radio device and in accordance with the first RAT using the determined transmission properties.
