    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 an example embodiment, a network node transmits secondary signal component of a combined wireless communication signal to a user equipment. The combined wireless communication signal includes the secondary signal component and a primary signal component. Secondary pilot resources of the secondary signal component are dynamically shifted relative to primary pilot resources of the primary signal component by an amount that is based on whether a current estimation procedure at the user equipment is a primary channel estimation procedure or a secondary channel estimation procedure. In a corresponding example embodiment, the user equipment receives the combined wireless communication signal with the dynamically shifted pilot resources. The user equipment estimates the primary channel in the primary channel estimation procedure and estimates the secondary channel in the secondary channel estimation procedure.

    摘要: The antenna weight selection solution disclosed herein selects antenna weights for a multiple antenna communication system that transmits uplink or downlink data using multiple radiation patterns based on channel variability metrics determined for two or more sets of candidate antenna weights. In so doing the antenna weight selection solution disclosed herein reduces the channel variability associated with data transmissions, and therefore reduces the amount of feedback and/or the feedback rates required for the multiple antenna communication system.

    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.
