LLR COMPRESSION IN WIRELESS COMMUNICATIONS NETWORKS

Abstract: at least one example embodiment provides a radio access network element comprising at least one processor and at least one memory. the at least one memory stores instructions that, when executed by the at least one processor, cause the radio access network element to: extract sign information from a plurality of log-likelihood ratio (llr) sample values included in llr data in a resource block group (rbg); convert negative llr sample values, from among the plurality of llr sample values, into positive integer values to obtain converted llr data; generate compressed llr data based on the converted llr data; and output the compressed llr data.
