Abstract: Methods, apparatuses, and computer-readable media are provided including approaches for partial code block group (CBG)-based link adaptation in wireless communication. An apparatus sends a message to a wireless device indicating a partial CBG, and obtains retransmitted data in the partial CBG and additional data in the remainder of the CBG in response to a non-acknowledgment of the CBG. The partial CBG is based on mutual information between the apparatus and the wireless device representing an average spectral efficiency observed from historical CBGs. Support for link adaptation based on the partial CBG may be indicated in capability information, and the granularity of the partial CBG may be confirmed prior to establishing a radio resource control connection. These methods boost throughput, provide efficient resource utilization, and ensure compatibility without compromising quality of service.

The first device then receives an adjusted OAM waveform from the second device, wherein the adjusted OAM waveform is received having a corrected spatial alignment with respect to the second device based on the report.
