A method for a wireless device, a wireless device, a method for a network node, and a network for acquiring system information, SI, during sounding reference signals, SRS, carrier based switching, are provided. First it is determined a need for performing SRS carrier based switching from a first cell, cell1, operating on a first carrier frequency, F1, to a second cell, cell2, operating on a second carrier frequency, F2. Secondly a system information, SI, of a third cell, cell3, on a third carrier frequency, F3, during a time period, T1 is acquired.
