Wideband transmission with narrowband monitoring for new radio unlicensed spectrum (NRU)

A device comprising:

• radio circuitry configured to facilitate wireless communications of the device;
• and
• a processor communicatively coupled to the radio circuitry and configured to interoperate with the radio circuitry to:
• perform first wireless communications according to a first radio access technology (RAT) over a first carrier corresponding to a first frequency band, wherein wireless communications according to one or more other RATs also take place in the first frequency band;
• receive, as part of the first wireless communications, control information subsequent to a successfully completed listen-before-talk (LBT) procedure within a second frequency band, wherein the control information instructs the device to communicate over a second carrier corresponding to the second frequency band, wherein wireless communications according to one or more other RATs also take place in the second frequency band, wherein the second frequency band is not contiguous with the first frequency band;
• communicate over the second carrier while also communicating over the first carrier in response to receiving the control information;
• and
• cease communicating over the second carrier at least in response to a channel occupancy time for present wireless communications of the device ending.

A non-transitory memory element storing instructions executable by a processor to cause a device to:

• perform first wireless communications according to a first radio access technology (RAT) within a first bandwidth part (BWP) of a first frequency band, wherein wireless communications according to one or more other RATs also take place in the first frequency band;
• receive, as part of the first wireless communications, control information subsequent to a successfully completed listen-before-talk (LBT) procedure within a specified portion of a second BWP of the first frequency band, wherein the second BWP contains the first BWP and the first BWP does not contain the specified portion of the second BWP;
• begin communicating within the second BWP in response to receiving the control information;
• and
• switch back from communicating within the second BWP to communicating within the first BWP at least in response to a channel occupancy time for present wireless communications of the device ending.
