摘要： The antenna weight selection solution disclosed herein selects antenna weights for a multiple antenna communication system that transmits uplink or downlink data using multiple radiation patterns based on channel variability metrics determined for two or more sets of candidate antenna weights. In so doing the antenna weight selection solution disclosed herein reduces the channel variability associated with data transmissions, and therefore reduces the amount of feedback and/or the feedback rates required for the multiple antenna communication system.

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： 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 in accordance with one embodiment be communicated with by forwarding data over multiple hops. The wireless nodes are adapted to perform sensing of at least one radio resource in response to a request from a node. Based on the collective information from at least one other wireless nodes a wireless node can make an improved decision if a particular radio resource is free to use or not.

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： A method 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 is provided. A model of propagation channels from each of the white space units to each of the at least one point includes a variable with a lognormal distribution. The method comprises receiving requests for usage of white space frequency channels from the white space units. The requests include positions of the white space units. Output power limits are determined for the 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. A sum of lognormal variables in the probabilistic constraint is approximated by a single lognormal variable. The determined output power limits are then transmitted to the respective white space units.

摘要： A network node (110) and a method therein for managing radio, resources are disclosed. The radio resources are dedicated for beacon (121, 122) signaling, fey a first device; (131) and a second device (132), in conjunction with device-to-device, “D2D”, discovery. The first device: (131) is stationary and the second device (132) is non-stationary. The network node (110) selects (202) a first and a second set of radio resources out of the radio resources. The first and second sets are dedicated for beacon signaling by the first device (131) and the second device (132), respectively. The first set of radio resources Is non-overlapping with the second set of radio resources. Then the network node (110) schedules (203) a specific radio resource of the first set of radio resources to the first device (131). Next, the network node (110) sends (204) information about the scheduled specific radio resource to the first device (131). The network node (110) further sends (205) information about the second set of radio resources to the second device (132). In this manner, the second device (132) restricts Us radio resources usable for beacon signaling to the second set of radio resources.
