Resource format indicators in bandwidth part management for full-duplex resource allocation

A method for wireless communication at a network entity, comprising:

• communicating with a user equipment (UE) using an operating bandwidth part that comprises a first set of frequency resources of a carrier bandwidth;
• transmitting group-common downlink control information that comprises a resource format indicator indicating a second set of frequency resources;
• modifying the operating bandwidth part based at least in part on the group-common downlink control information, wherein modifying the operating bandwidth part comprises reducing the operating bandwidth part to a subset of the first set of frequency resources that overlap with the second set of frequency resources;
• and
• communicating with the UE using the modified operating bandwidth part.

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

• receiving group-common downlink control information comprising a resource format indicator associated with a time period;
• determining that a set of symbols within the time period has a full-duplex format based at least in part on the resource format indicator and a configuration for interpreting resource format indicators;
• determining a downlink frequency resource allocation and an uplink frequency resource allocation for the set of symbols having the full-duplex format based at least in part on the group-common downlink control information and the configuration;
• and
• communicating with a network entity using the uplink frequency resource allocation and the downlink frequency resource allocation during the set of symbols.

A method for wireless communication at a network entity, comprising:

• determining a downlink frequency resource allocation and an uplink frequency resource allocation for a set of symbols having a full-duplex format based at least in part on a configuration for interpreting resource format indicators;
• transmitting group-common downlink control information comprising a resource format indicator associated with a time period that includes the set of symbols, wherein a first portion of the resource format indicator indicates the full-duplex format of the set of symbols and a second portion of the resource format indicator indicates both the downlink frequency resource allocation and the uplink frequency resource allocation for the set of symbols having the full-duplex format;
• and
• communicating with a user equipment (UE) using the downlink frequency resource allocation and the uplink frequency resource allocation during the set of symbols.

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:
• communicate with a network entity using an operating bandwidth part that comprises a first set of frequency resources of a carrier bandwidth;
• receive group-common downlink control information that comprises a resource format indicator indicating a second set of frequency resources;
• modify the operating bandwidth part based at least in part on the group-common downlink control information, wherein, to modify the operating bandwidth part, the instructions are executable by the processor to cause the apparatus to reduce the operating bandwidth part to a subset of the first set of frequency resources that overlap with the second set of frequency resources;
• and
• communicate with the network entity using the modified operating bandwidth part.
