According to some embodiments, a method in a radio network element of providing hybrid automatic repeat request (HARQ) feedback comprises receiving, from a wireless transmitter, a first set of coded bits. The first set of coded bits comprises a partial subset of coded bits to be received during a transmission time interval (TTI). The radio network element decodes the first set of coded bits; determines a first decoding indicator based on the success or failure of the decoding of the first set of coded bits; and communicates the first decoding indicator to the wireless transmitter. Particular embodiments communicate the first decoding indicator to the wireless transmitter within four TTI of receiving the first set of coded bits. Particular embodiments estimate a decoding indicator for the entire TTI based on the success or failure of the decoding of the first set of coded bits.
