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 technology described in this application provides a wide-area radio access information transmission scheme where the wide-area radio access information transmitter shares its radio resources with local radio access information transmitters. The radio resources may be divided for example in one or more of the time, frequency, space, and/or code domains. The wide-area radio access information transmitter sets aside and does not use some portions or "chunks" of its radio resources and allocates those unused portions or chunks for use by local radio access information transmitters to transmit local radio access information signals. In one non-limiting example embodiment, the radio resources include time slots, and during those time slots allocated to the local radio access information transmitters, the wide-area radio access information transmitter does not transmit, and thus, is quiet. Hence, those allocated time slots are referred to as "quiet periods" from the perspective of the wide-area radio access information transmitter. The wide-area radio access information transmitter can optionally explicitly signal what those resources are to simplify for the local radio access information transmitters who otherwise have to detect those resources themselves.
摘要翻译：本申请中描述的技术提供了一种广域无线电接入信息传输方案，其中广域无线电接入信息发射机与本地无线电接入信息发射机共享其无线电资源。无线电资源可以例如在时间，频率，空间和/或代码域中的一个或多个中被划分。广域无线电接入信息发射机放在一边并且不使用其无线电资源的一些部分或“块”，并且分配这些未使用的部分或块以供本地无线电接入信息发射机使用以发送本地无线接入信息信号。在一个非限制性示例实施例中，无线电资源包括时隙，并且在分配给本地无线电接入信息发射机的那些时隙期间，广域无线接入信息发射机不发射，因此是安静的。因此，从广域无线电接入信息发送器的角度来看，这些分配的时隙被称为“安静时段”。广域无线电接入信息发射机可以可选地明确地信令那些资源为了简化本地无线电接入信息发射机而需要简化的，否则本地无线接入信息发射机必须自己检测这些资源。

摘要： The technology disclosed provides the ability for a subframe to be configured as a "flexible" subframe. As a result, at least three different types of sub frames in a TDD system may be configured: a downlink ("DL") subframe, an uplink ("UL") subframe, and a "flexible" subframe. While the DL and UL subframes are preconfigured for each frame instance, the flexible subframes are dynamically allocated to be an uplink subframe in one instance of a frame and a downlink subframe in another instance of the frame.

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.
