1. One or more non-transitory, computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors of a remote radio unit (RRU) cause the RRU to:
receive a multiple input, multiple output (MIMO) signal from one or more user equipments (UEs);
obtain channel measurements associated with a first UE of the one or more UEs on respective channels of a plurality of channels;
perform maximum ratio combining (MRC) on the MIMO signal based on the channel measurements of the plurality of channels to generate a processed signal; and
send the processed signal to a baseband unit (BBU) to decode data from the processed signal, wherein the plurality of channels are associated with different time domain resources, different frequency domain resources, and/or different spatial domain resources.
