Abstract

A method in a sending node of a communications network includes: encoding a transport block, TB, including data of at least one protocol data unit, PDU, to generate a code block group, CBG, comprising one or more code blocks; defining a CBG header indicative of a starting location of a first PDU within the CBG; and transmitting the CBG including the CBG header. A method in a receiving node includes: receiving one or more code block groups, CBGs, each CBG comprising a CBG header indicative of a start location of a first protocol data unit, PDU, within the CBG; attempting to decode each received CBG; responsive to failing to decode a first CBG, attempting to decode a second CBG, and responsive to successfully decoding the second CBG: identifying the start location of the first PDU in the second CBG; buffering data of the second CBG prior to the identified start location; and forwarding data of PDUs following the identified start location.
