摘要： A method in a wireless communication network 100 for assisting a user equipment 130 to receive signals from a target access node 122. The wireless communication network 100 comprises the target access node 122, the user equipment 130 and a serving access node 120 serving the user equipment 130. The serving access node 120 sends information about time instances to the user equipment 130. The time instances are scheduled for sending signals from the target access node 122 in a beam direction 220 towards the user equipments 130. The time instances may be determined in the target access node 122 based on its own position and a position of the user equipment 130 and/or a beam direction 210 of the serving access node. The time instances may also be determined in the serving access node 120 based on its own position and a schedule of the target access node 122 on beam directions versus transmission times. The user equipment 130 receives signals from the target access node 122 during the time instances indicated in the received information. In this way, leaving more time for the user equipment to receive data or signal from the serving access node 120. As a result, the throughput of the wireless communication network is increased and improved.

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.
