Determining transmission configurations for resource block groups and precoding resource block groups

A method for wireless communications at a first device, comprising:

• identifying a transmission configuration for a carrier bandwidth allocated for communications with a second device, the transmission configuration indicating a resource block group size and a bandwidth part size;
• determining whether a sum of the bandwidth part size and a start resource block of a bandwidth part of the carrier bandwidth modulo the resource block group size is less than or equal to the resource block group size;
• designating the resource block group size for the transmission configuration as equal to the bandwidth part size based at least in part on the determining;
• and
• communicating with the second device using the carrier bandwidth according to the transmission configuration.

A first wireless device, comprising:

• a processor;
• a transceiver in electronic communication with the processor;
• and
• memory in electronic communication with the processor, the processor configured to:
• identify a transmission configuration for a carrier bandwidth allocated for communications with a second device, the transmission configuration indicating a resource block group size and a bandwidth part size,
• calculate a number of resource block groups for the transmission configuration based at least in part on the resource block group size and the bandwidth part size and according to a first resource allocation type,
• designate the resource block group size for the transmission configuration as equal to the bandwidth part size based at least in part on the calculated number of resource block groups being equal to one, and
• communicate, via the transceiver, with the second device using the carrier bandwidth according to the transmission configuration.
