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 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.
摘要翻译：本发明提出了用于改进协作频谱启动感测的方法和相应装置。设备（61; 61.1）首先接收参与协作频谱感测的邀请（17; 35）。设备响应于该邀请执行是否参与协作频谱感测的自主决定（19）。如果决定参与与邀请相关的协作频谱感知，则进行频谱感测（21; 45）。利用本发明，传感器选择变得“分散”，即由设备本身来决定参与协作感测，而不是具有例如确定哪些设备应当用作协作频谱感测中的传感器的中央实体。一个优点是可以将传感器选择所需的信号量保持在最低限度，从而节省通信资源。

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： A method and an arrangement (400) for determining an admission control threshold for use in an admission control procedure are provided. The admission control procedure manages a first spectrum resource (R1). The first spectrum resource (R1) has a first spectrum resource capacity and a first available spectrum resource capacity, wherein the first available spectrum resource capacity has a time dependence. In a step (220), the admission control threshold is determined based on the first spectrum resource capacity and a measure of the time dependence of the first available spectrum resource capacity.
