摘要： The invention presents methods and corresponding devices for improving cooperative spectrum initiating 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 invention relates to a method of a node such as a geo-location database, for controlling an aggregated interference generated by at least two white space units in at least one point in space for at least one frequency channel. A model of propagation channels from each of the at least two white space units to each of the at least one point comprises a variable with a lognormal distribution. The method comprises receiving (810) requests for usage of white space frequency channels from the at least two white space units, the requests comprising positions of the at least two white space units. The method also comprises determining (820) output power limits for the at least two white space units by maximizing a utility function while fulfilling a probabilistic constraint on the amount of aggregated interference generated in each of the at least one point, based on the received requests and on said model of propagation channels. A sum of lognormal variables in the probabilistic constraint is approximated by a single lognormal variable. The method further comprises transmitting (830) the determined output power limits to the respective at least two white space units.

摘要： The disclosure relates to a network node of a wireless network, and to a related method for determining a margin of an interference level. The network node controls at least one white space device, and the interference level is associated with a critical position and a channel available for secondary usage by the at least one white space device. The method comprises the following steps: (a) initializing (410) the margin; (b) determining (420) a transmit power level for the at least one white space device when transmitting on the channel available for secondary usage, based on the interference level with the margin added; (c) calculating (430) a probability that an aggregated interference from the at least one white space device at the critical position exceeds the interference level, based on the determined transmit power level and a channel model uncertainty; and (d) modifying (440) the margin of the interference level if the calculated probability falls outside of a probability interval. The method also comprises iterating the steps (b), (c), and (d) until the calculated probability falls within the probability interval.

摘要： A local radio access information transmitter (LRAIT) may be used in a communications area serviced by multiple different radio access technologies (RATs) allocated to different radio resources in different locations in the communications area. Each RAT is associated with RAT radio transceiver(s) for serving UEs in the communications area. The LRAIT is in addition to the RAT transceivers and located near a hotspot service area in the communications area. The LRAIT determines local radio access information (LRAI) including different RATs available in the hotspot service area and frequenc(ies) of operation allocated to each RAT in the hotspot service area, sends a registration message to a wide area radio access information controller, and based on a response therefrom, determines what radio resources to use to transmit the LRAI signals. The LRAIT transmits the LRAI signals for receipt by UEs in the hotspot service area using those radio resources.

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.

摘要： The disclosure relates to a white space device (WSD) of a secondary wireless network, and to a related method for transmitting a first signal on a channel available for secondary usage allocated to a primary wireless system. The method in the WSD comprises determining (410) a further channel used by the primary wireless system, that would be interfered by a transmission of the first signal on the channel available for secondary usage, retrieving (420) signal information associated with the determined further channel from the primary wireless system, transmitting (430) the first signal on the channel available for secondary usage, and transmitting (440) a second signal on the determined further channel based on the retrieved signal information, simultaneously with the first signal on the channel available for secondary usage* such that an interference generated in the primary wireless system by the first signal transmission is compensated for by the second signal transmission.

摘要： The present invention relates to a solution for wireless communication and in particular for facilitating connection to a radio access network. This is provided in a number of aspects such as method, devices, and system. The solution comprises using a local short range communication connection between two user equipments, UEs, (101, 102) for assisting each other in connecting to a radio access network, RAN (103). One UE is often an always on UE and one is often a sporadic use UE. The always on UE has normally an active connection with the RAN and has knowledge about valid radio access technologies, RAT. The sporadic use UE may connect with the always on UE with a trusted connection and negotiate for information about available RATs and use this information for faster connection with the RAN. The two UEs may together scan for available RATs by dividing frequency bands and each searching different parts and thus reducing the scan process and reducing resource use.

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.
