Abstract
Various features pertain to mitigating interference on downlink/uplink channels caused by bursty traffic transmissions. A transmitting node encodes data into transport blocks, each including code blocks in which the data is encoded. The transport blocks are then wirelessly transmitted over a channel specific to a receiving node, where the code blocks of the transport blocks are transmitted without redundant parity code blocks or with a desired amount of redundant parity code blocks. The transmitting node then receives an indication from the receiving node of a number of failed data code blocks. The transmitting node generates an error correction code sufficient to recover all of the failed code blocks and transmits the error correction code within a new transport block along with new data. The receiving node receives the new transport block including the error correction code and then recovers the failed code blocks from the error correction code via erasure decoding, a combination of erasure decoding and error decoding, and/or other suitable techniques at the code block level.
