Techniques for enabling bandwidth adaption via group-based downlink control information

A network entity, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the network entity to:
• transmit first control signaling indicative of a configuration of a bandwidth part;
• transmit second control signaling indicative of a plurality of sub-configurations associated with the bandwidth part, the plurality of sub-configurations including a first sub-configuration associated with a first sub-portion of the bandwidth part and a second sub-configuration associated with a second sub-portion of the bandwidth part, wherein the first sub-portion is different than the second sub-portion;
• transmit a group-based downlink control information message indicative of which one of the first sub-configuration or the second sub-configuration is activated;
• and
• communicate, based at least in part on the group-based downlink control information message, one or more messages in accordance with activation of one of the first sub-configuration or the second sub-configuration.

A method for wireless communications at a user equipment (UE), comprising:

• receiving first control signaling indicative of a configuration of a bandwidth part;
• receiving second control signaling indicative of a plurality of sub-configurations associated with the bandwidth part, the plurality of sub-configurations including a first sub-configuration associated with a first sub-portion of the bandwidth part and a second sub-configuration associated with a second sub-portion of the bandwidth part, wherein the first sub-portion is different than the second sub-portion;
• receiving a group-based downlink control information message indicative of which one of the first sub-configuration or the second sub-configuration is activated;
• and
• communicating, based at least in part on the group-based downlink control information message, one or more messages in accordance with activation of one of the first sub-configuration or the second sub-configuration.
