Various embodiments of the present disclosure disclose methods and apparatuses for improved uplink low layer separation to support advanced CoMP. Methods and systems for implementing or assisting joint equalization, DMRS-based joint equalization, or maximal ratio combining are described. In certain embodiments, a DU requests a RU to transmit both equalized DMRS symbols and equalized data symbols when indicated by a scheduler. The DU can use the equalized DMRS symbols to estimate an effective channel, including equalization made in the RU. The DU then uses the effective channel estimate to implement joint equalization or DMRS-based joint equalization on the equalized data symbols received from one or more RUs.
