A method, network node, wireless device and system are provided. In one or more embodiments, the network node is configured to communicate with a wireless device. The network node includes processing circuitry configured to: determine to transition the wireless device to one of a beamforming mode and non-beam forming mode, in response to the determination to transition the wireless device, modify at least one measurement report trigger associated with the wireless device, and transmit an indication of the modification of the at least one measurement report trigger to the wireless device.

Methods for modification of at least one measurement reporting trigger for biased measurements at the wireless device

Systems and methods for Secondary Cell (sCell) selection for wireless devices operating according to a carrier aggregation scheme in a cellular communications network are disclosed. In one embodiment, a network node in the cellular communications network obtains geographic signatures for a number of candidate sCells. The geographic signatures include a geographic signature for each candidate sCell that approximates a coverage area of the candidate sCell. The network node obtains position information for a wireless device and then selects one or more sCells for the wireless device from the candidate sCells based on the geographic signatures for the candidate sCells and the position information for the wireless device. The network node then configures the selected sCell(s) for use by the wireless device according to a carrier aggregation scheme. Using this process, sCell selection is performed, in some examples, without measurement gaps and without disabling an s-Measure parameter.

Secondary cell selection based on geographic signatures

Systems and methods for Secondary Cell (sCell) selection for wireless devices operating according to a carrier aggregation scheme in a cellular communications network are disclosed. In one embodiment, a network node obtains a list of potential sCells for a wireless device. The network node blindly selects an sCell for the wireless device from the list of potential sCells. The network node then configures the wireless device with the selected sCell. Blindly selecting the sCell for the wireless device makes it possible to avoid the use of measurement gaps and reduce throughput loss, according to some embodiments.
