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 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： The invention comprises a method and a corresponding apparatus (53). A candidate set of sensors that are available to participate in an occasion of cooperative spectrum sensing is obtained. For each sensor in the candidate set, its radial distance to a central coordinating node in a communication system is also obtained (73). A sequence of minimum radii is produced (75,79). For each minimum radius in the sequence, an accommodation number is determined (75,87). The accommodation number associated with a minimum radius is the greatest number of sensors that can be placed on circle having this radius without a probability that all these sensors are mutually uncorrelated falling below a design probability threshold. Sensors from the candidate set are then selectively added (91,95) to an active set of sensors based on the minimum radii, the corresponding accommodation numbers and the obtained radial distances.

摘要： The invention presents methods and corresponding device relating to cooperative spectrum sensing. First a candidate set of sensors that can participate in an occasion of cooperative spectrum sensing is obtained. A cost formula for calculating a cost associated with using sensors from the candidate set in the cooperative spectrum sensing is then defined (75; 107, 97). The candidate set is partitioned (29; 14, 145) into an active set and a passive set. The active set contains any sensor (s) from the candidate that is to participate in the cooperative spectrum sensing. The passive set includes any sensor (s) that is not to participate in the cooperative spectrum sensing. The partitioning of the candidate set is done by applying an optimization procedure (79, 81, 83; 111, 113, 115) which performs a constrained optimization of the cost in accordance with the defined cost formula.

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 (10). 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 (1,2,3) 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(1,2,3) perform their transmissions in accordance with the received rules.

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.
