Abstract
There is provided a technique of decoding an uplink in a multiple input multiple output wireless communication system in an open radio access network having an open distributed unit (O-DU) and an open radio unit (O-RU). The O-DU (a) constructs a combining matrix for a resource block, and (b) sends the combining matrix to the O-RU. The O-RU (a) utilizes the combining matrix to compress signals on NR antennas per subcarrier into M values, where NR is a number of antennas, and M is less than NR, and (b) sends the M values per subcarrier to the O-DU.
