This disclosure describes systems, methods, and devices related to subband media access control protocol data unit (MPDU) aggregation. A device may determine a first subband and a second subband of a frequency band associated with a communication channel with a first device. The device may allocate a first MPDU to the first subband. The device may allocate a second MPDU to the second subband. The device may cause the first MPDU to be wirelessly transmitted to the first device over the communication channel using a first modulation and coding scheme (MCS) value associated with the first subband. The device may cause the second MPDU to be wirelessly transmitted to the first device over the communication channel using a second MCS value associated with the second subband.
