Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a set of downlink control information (DCI) messages each scheduling a data channel, for example, a first DCI message of the set of DCI messages schedules a first physical uplink shared channel (PUSCH) and a second DCI message of the set of DCI messages schedules a second PUSCH. The UE may determine a first frequency hopping pattern associated with the first PUSCH and a second frequency hopping pattern associated with the second PUSCH, and align the first frequency hopping pattern with the second frequency hopping pattern. Based on the aligned frequency hopping patterns, the UE may transmit the first PUSCH and the second PUSCH. The aligned frequency hopping patterns may thus reduce an interference between multiple PUSCH and improve channel estimation for the UE.
