    Abstract: The present application describes a WTRU including a non-transitory memory including instructions stored thereon for re-establishing a remote radio control (RRC) connection with a base station. The apparatus also includes a processor capable of executing instructions of determining, based upon a measurement in an active downlink bandwidth part (DL BWP), to initiate a random access channel (RACH) procedure. The processor also executes instructions of switching to a default uplink bandwidth part (UL BWP). The processor also executes instructions of initiating the RACH procedure. The process further executes instructions of transmitting a RA preamble using one of the RACH resources configured for the default UL BWP. The processor even further executes instructions of receiving a RA response. The processor yet even further executes instructions of switching from the default UL BWP to either an active UL BWP or another active UL BWP after re-establishing the RRC connection.

    Abstract: A wireless device, such as user equipment (UE) or other apparatus, like may use a transparent mode operation in which the device is not aware of the operation mode of abase station, such as a gNB or other transmission and receive point (TRP), via the use of configurations for Frame Based Equipment (FBE) and Load Based Equipment (LBE) operating modes. A base station may initiate a Channel Occupancy Time (COT) that is an FBE COT or an LBE COT, in which the wireless device follows FBE or LBE procedures accordingly. A variety of criteria may be applied in determining whether to use FBE or LBE procedures, and to switch between them. A network may use indicate the intention to switch operation mode and may do so via implicit or explicit indications. Similarly, a wireless device may autonomously switch operation mode, and may indicate the selected mode to the network.
