摘要： There is provided mechanisms for performing an iterative learning process with agent entities. A method is performed by a server entity. The method comprises selecting a linear mapping to be used by the agent entities when reporting computational results of a computational task to the server entity. The linear mapping has an inverse. The linear mapping is selected as a function of an estimated interference level for a radio propagation channel over which the agent entities are to report the computational results of the computational task to the server entity. The method comprises configuring the agent entities with the computational task. The method comprises performing the iterative learning process with the agent entities until a termination criterion is met. The server entity as part of performing the iterative learning process applies the inverse of the linear mapping to a sum of the computational results received from the agent entities.

摘要： Methods and apparatus in a communications network as described herein are suitable for determining a first model for use in predicting conditions on carrier frequencies in the communications network. In a method, network measurements are obtained (302) of conditions on a plurality of carrier frequencies. A first model is then determined (304) based on the obtained measurements that takes as input the conditions on a first subset of the plurality of carrier frequencies and outputs a prediction of the conditions on a second subset of the plurality of carrier frequencies, based on the conditions of the first subset of carrier frequencies.

System information may be obtained from the neighbor cell, with the system information indicating that the neighbor cell does not broadcast a cell identifier. The timer may be stopped before expiration of the timer responsive to obtaining the system information including the indication that the neighbor cell does not broadcast the cell identifier of the neighbor cell.

摘要： Method and one or more nodes (210; 230; 240; 310; 510) for providing synchronization signals of a wireless communication network (200). Transmission is initiated (701) of a first set of radio beams (212a-b; 312a-d; 512a-d) comprising Synchronization Signal Blocks, "SSBs", respectively, for enabling a wireless device (220; 320; 520) receiving such SSB to establish connection with the wireless communication network (200). Said SSBs of the first set belong to a certain sequence of SSBs and thereby associated with SSB sequence numbers, respectively. Transmission is initiated (702) of a second set of radio beams (213a-b; 313a-d; 513a-d) comprising SSBs, respectively, also belonging to said certain sequence. The second set comprises at least one changed radio beam (213b; 313d; 513a-d) comprising a SSB associated with the same sequence number as a SSB of a radio beam (212b; 312d; 512a-d) of the first set but covering another area, whereby a total area (218; 318; 518) covered by the first set and second set in combination becomes larger than covered by each set alone.

摘要： Network node (111) and method therein for assisting a user equipment (130) to handle a connection in a wireless communication network (100) are disclosed. A first network node (111) and a second network node (112) operate in the wireless communication network (100). The first network node (111) is a serving network node for the user equipment (130). The first network node (111) determines that the user equipment (130) is under an idle mode coverage of the second network node (112) based on measurements associated to the user equipment (130). When a connected mode connection between the user equipment (130) and the first network node (111) is released, the first network node sends a context of the user equipment (130) to the second network node (112).

摘要： There is provided mechanisms for configuring agent entities with a reporting schedule for reporting computational results during an iterative learning process. A method is performed by a server entity. The method comprises configuring the agent entities with a computational task and a reporting schedule. The reporting schedule defines pairs of the agent entities. According to the reporting schedule and per each iteration of the learning process, each of the agent entities in each pair is to report its own computational result of the computational task to both the server entity and the other of the agent entities in the same pair. When reporting its own computational result to the server entity, each of the agent entities is to superimpose the computational result of the other of the agent entities in the same pair. The method comprises performing the iterative learning process with the agent entities until a termination criterion is met.
