Communicating across a wideband using sub-bands

A method for wireless communications at a base station, comprising:

• identifying a carrier bandwidth for communicating a wideband communication with a user equipment (UE);
• transmitting, to the UE, a configuration for communicating with the base station in the carrier bandwidth using a plurality of sub-band based communications that are over a plurality of sub-bands spanning the carrier bandwidth;
• and
• communicating with the UE in the carrier bandwidth using one or more of the plurality of sub-bands in accordance with the configuration.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify a carrier bandwidth for communicating a wideband communication with a base station;
• receive, from the base station, a configuration for communicating with the base station in the carrier bandwidth using a plurality of sub-band based communications that are over a plurality of sub-bands spanning the carrier bandwidth;
• and
• communicate with the base station in the carrier bandwidth using one or more of the plurality of sub-bands in accordance with the configuration.
