1. A method, comprising:
at a user equipment (UE) connected to a network:
identifying a predetermined condition corresponding to one or more uplink listen-before-talk (LBT) failures associated with a special cell (SpCell), wherein the UE is triggered to provide an indication of uplink LBT failure associated with the SpCell to the network based on the predetermined condition;
determining a type of message that is to be used to deliver the indication of uplink LBT failure associated with the SpCell to the network, wherein the type of message is an indication of bandwidth part (BWP) switching by the UE that is to be transmitted to a secondary cell (SCell);
transmitting the type of message including the indication of uplink LBT failure associated with the SpCell to the network; and
determining that the network received the indication of uplink LBT failure associated with the SpCell.
