18 Claims

1. A method for a source network node, the method comprising:

connecting with a user equipment (UE);

determining that the source network node is to handover the UE to a target network node using dynamic spectrum sharing (DSS) with uplink (UL)-shifting;

transmitting, to the UE, a first message comprising a cell barred field;

transmitting, to the UE, a second message comprising a second field related to barring UEs that support DSS with uplink-shift, and a third field related to support of UL-shift, wherein the second field is an exemption field which explicitly expresses whether UEs which support DSS with UL-shift are allowed to camp or not when the cell barred field is set to barred, and wherein the third field is a frequnecyShift7p5khz field;

receiving a report indicating whether the UE supports the DSS with UL-shifting, wherein the report is based on the first message and the second message; and

performing a handover of the UE to the target network node if the UE supports DSS with UL-shifting.
