摘要： Apparatuses and methods are disclosed relating a WD-specific beam cell. In one embodiment, a method implemented in a network node includes obtaining angular information using a first radio access technology, RAT, the angular information being associated with a wireless device, WD, the first RAT supporting a first coverage area and a first data rate for the WD. A beam to be used by a second RAT to support a second coverage area and a second data rate for the WD is determined, the beam being determined for the second RAT being based at least in part on the angular information obtained from the first RAT, the second coverage area being narrower than the first coverage area and the second data rate being higher than the first data rate. A handover of the WD from the first RAT to the second RAT is undertaken.

摘要： Systems and methods relating to adjusting uplink coverage in a cellular communications network are disclosed. In some embodiments, a method of operation of a network node to adjust uplink coverage for one or more cells in a cellular communications network comprises determining that there is a need to adjust uplink beam transformations for one or more cells of a plurality of cells in a cellular communications network. For each cell of the one or more cells, the uplink beam transformation for the cell is a transformation of received uplink signals for the cell from an antenna domain to a beam domain. The method further comprises, upon determining that there is a need to adjust the uplink beam transformations for the one or more cells, determining new uplink beam transformations for the one or more cells and applying the new uplink beam transformations for the one or more cells.
