There is provided mechanisms for transmission of NR control information in a LTE downlink subframe. At least two symbols in the subframe are allocatable for LTE control information. A method is performed by a network node. The method comprises obtaining information that the symbol at index 1 in the subframe allocatable for LTE control information is to be allocated to the NR control information. The method comprises, in response thereto, configuring resource elements for LTE transmission and resource elements for NR transmission within the subframe. The resource elements for LTE transmission in the symbol at index 1 in the subframe are to be muted. The NR control information is allocated to resource elements of the symbol at index 1 in the subframe. The method comprises initiating transmission of the subframe.

Assigning resources for control signalling for a wireless device is described wherein the resources can be used for user data when not used for control signalling. A network node obtains a collection of at least one configuration group, wherein each configuration group refers to a selection of the resources; determines a load for each one of the configuration groups; when no configuration group of the collection has a load which is less than a first threshold value, instantiates a new configuration group referring to a selection of the resources, and assigns at least part of the resources of the new configuration group to the wireless device; and when there is a first configuration group in the collection having a load which is less than the first threshold value, assigns at least part of the resources of the first configuration group to 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.

Systems and methods are disclosed for autonomously determining overlapping coverage in a cellular communications network. In one embodiment, the cellular communications network is a heterogeneous cellular communications network. In one embodiment, a network node of a cellular communication system obtains information (e.g., pilot reports) indicative of a perceived coverage of one or more covering cells at wireless devices within a measuring cell over a measurement interval. The network node determines overlapping coverage of the measuring cell and the one or more covering cells based on the information indicative of the perceived coverage of the one or more covering cells at the wireless devices.
