Abstract

Certain aspects of the present disclosure relate to methods and apparatus for management of hybrid automatic repeat request (HARQ) log likelihood ratio (LLR) and reordering buffers in wireless communication systems. According to certain aspects, a method for reducing buffer overhead that may be performed by a wireless node is provided. The method generally includes receiving one or more packets of at least one of an initial transmission or a retransmission; forming one or more log likelihood ratios (LLRs) based on the one or more packets; compressing the one or more LLRs by quantizing the one or more LLRs; and buffering the one or more compressed LLRs.
