Methods and devices for acquiring system information

A wireless device configured for operation in a wireless communication network comprising at least a network node, a first cell, a second cell, and a third cell;

• the wireless device configured for acquiring system information (SI) during sounding reference signals (SRS) carrier based switching, the wireless device comprising:
• radio transceiver circuitry configured to send signals to the wireless communication network and to receive signals from the wireless communication network;
• and
• processing circuitry operatively associated with the radio transceiver circuitry and configured to:
• determine a need for performing SRS carrier based switching from a first cell operating on a first carrier frequency, to a second cell operating on a second carrier frequency;
• acquire SI of a third cell on a third carrier frequency during a time period T1;
• and
• transmit a minimum number of uplink feedback signals in the first cell in response to receiving downlink data in the first cell, wherein the minimum number of uplink feedback signals in the first cell is dependent on whether SRS switching causes interruption on first cell.

A method for a network node, connected to a wireless device in wireless communication network, for system information (SI) handling during sounding reference signals (SRS) carrier based switching, the method comprising:

• determining a need for a wireless device for performing SRS carrier based switching from a first cell operating on a first carrier frequency, to a second cell operating on a second carrier frequency;
• determining the need for a wireless device to acquire SI of a third cell on a third carrier frequency during a time period T1;
• and
• determining a minimum number of uplink feedback signals in the first cell that a wireless device transmits in response to receiving downlink data in the first cell, wherein the minimum number of uplink feedback signals in the first cell is dependent on whether SRS switching causes interruption on the first cell.
