1. One or more non-transitory computer-readable media (NTCRM) having instructions stored thereon, that when executed by one or more processors cause a remote radio unit (RRU) to:
receive a signal associated with an extended channel that includes a channel of one or more user equipments (UEs) served by the RRU and interference samples that correspond to other cells or additive noise;
scale the interference samples by a scaling coefficient to obtain a modified extended channel;
perform maximum ratio combining (MRC) of the received signal based on the modified extended channel to obtain a processed signal, wherein the MRC is performed using a different granularity for measurements of the channel than for measurements of the interference samples; and
transmit the processed signal to a baseband unit (BBU) via a fronthaul link.
