摘要： A method for a network node, a method for a relay wireless device, a method for an out of coverage wireless device, a network node, and a relay wireless device, an out of coverage wireless device are presented. The network node serves a cell in which a relay wireless device is at least partially located, the network node provides at least partial network coverage for the relay wireless device located in the cell, and an out of coverage wireless device is at least partially out of network coverage from the network node. The method includes determining that the network node should control the out of coverage wireless device. The method further includes determining D2D control information to be used for controlling the out of coverage wireless device, and transmitting the D2D control information to the out of coverage wireless device via a relay wireless device.

摘要： Identification of network nodes (110a-c) of a first Radio Access Technology, “RAT”, and of a wireless communication network (100), which network nodes (110a-c) are at least potentially neighboring each other. Multiple information sets associated with multiple communication devices (120a-c), respectively, are obtained (204a-b; 401). Each communication device (120a-c) supports both the first RAT and another, second RAT. Each information set, thus associated with a communication device (120a), identifies a network node (110a) of the first RAT, and one or more network nodes (111a) of the second RAT that have been identified by the communication device (120a) when the communication device (120a) was associated with a communicative connection to said identified network node (110a) of the first RAT. The network nodes (110a-b) of the first RAT that are at least potentially neighboring each other are then identified (205; 402) based on the obtained multiple information sets.

摘要： The present disclosure relates to coverage monitoring and in particular it relates to determining radio coverage, e.g. for small cell deployment in a building. The disclosure relates to methods for coverage determination as well as to corresponding devices and computer programs. According to one aspect, the disclosure proposes a method, performed in a wireless device 10, of determining radio coverage. The method comprises obtaining S1 at least one path along which radio condition measurements are to be performed and performing S2 radio condition measurements along the at least one path. The method further comprises determining S3 position estimates, wherein at least some of the position estimates correspond to the radio condition measurements. The method further comprises determining S4a radio coverage using the radio condition measurements and corresponding position estimates and/or reporting S4b the radio condition measurements and the corresponding position estimates to a radio network node for determination of radio coverage in the radio network node.
