Various example embodiments relate to partial data transmission. A transmitter may receive at least one dataset for transmission. The dataset may be one of a plurality of datasets known to the transmitter and a receiver or to be signaled to the receiver. The transmitter may determine a first portion of the dataset. The size of the first portion may be determined based on a battery level indicator, a latency level associated with the dataset, a radio condition, or a network load. The receiver may recognize the dataset based on the first portion and/or at least one second portion transmitted by the transmitter. Apparatuses, methods, and computer programs are disclosed.
