Abstract
Techniques are provided for reduction of processing requirements for portions of a received transmission relative to processing requirements for other portions of the same transmission. Different coding schemes may be employed for portions of a data transmission. In some examples, a tail portion of a data transmission may use a coding scheme that had reduced processing requirements relative to other portions of the data transmission. The reduced processing requirements may allow a receiver to generate an acknowledgment of receipt relatively quickly, which may reduce latency for acknowledging receipt of a transmission.
