Abstract:
According to an aspect, there is provided an apparatus configured to perform the following. The apparatus performs radio measurements of one or more primary cells, PCells, and of primary secondary cells, PSCells, associated with the one or more PCells. Then, the apparatus evaluates a conditional handover, CHO, execution condition of the one or more PCells and a conditional PSCell addition/change, CPAC, execution condition of the PSCells based on the radio measurements. At least in response to the CPAC execution condition for a first PSCell being satisfied while the CHO execution condition for any PCell associated with the first PSCell is not satisfied, the apparatus relaxes or stops radio measurements of at least one PSCell.
