Resource block group sizes

An apparatus for wireless communications at 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 operable to execute the code to cause the one or more processors, individually or collectively, to:
• transmit a first control message comprising a first resource block group size parameter that indicates a first resource block group size configuration of a plurality of resource block group size configurations that associate bandwidth part sizes with resource block group sizes;
• transmit a single second control message of a first control information format that schedules a plurality of transmissions in a plurality of cells and comprises a corresponding plurality of frequency domain resource allocation fields indicating a plurality of resource block groups over which the plurality of transmissions are to be communicated, wherein a plurality of resource block group sizes for the plurality of cells are based at least in part on individual bandwidth part sizes associated with individual cells of the plurality of cells corresponding to individual resource block group sizes in the first resource block group size configuration;
• and
• communicate a first transmission of the plurality of transmissions in one or more resource block groups of the plurality of resource block groups in accordance with a first resource block group size of the plurality of resource block group sizes, wherein, for the first resource block group size configuration and for a bandwidth part size of one of the plurality of cells, the first resource block group size is selected from a first value corresponding to the first control information format and a second value corresponding to a second control information format.

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

• receiving a first control message comprising a first resource block group size parameter that indicates a first resource block group size configuration of a plurality of resource block group size configurations that associate bandwidth part sizes with resource block group sizes;
• receiving a single second control message of a first control information format that schedules a plurality of transmissions in a plurality of cells and comprises a corresponding plurality of frequency domain resource allocation fields indicating a plurality of resource block groups over which the plurality of transmissions are to be communicated, wherein a plurality of resource block group sizes for the plurality of cells are based at least in part on individual bandwidth part sizes associated with individual cells of the plurality of cells corresponding to individual resource block group sizes in the first resource block group size configuration;
• and
• communicating a first transmission of the plurality of transmissions in one or more resource block groups of the plurality of resource block groups in accordance with a first resource block group size of the plurality of resource block group sizes, wherein, for the first resource block group size configuration and for a bandwidth part size of one of the plurality of cells, the first resource block group size is selected from a first value corresponding to the first control information format and a second value corresponding to a second control information format.
