1. A baseband processor, the baseband processor configured to:
receive multiple input, multiple output (MIMO) uplink configuration information from a base station, wherein the MIMO uplink configuration information indicates a plurality of sounding reference signal (SRS) resources;
receive downlink control information (DCI) from the base station, wherein the DCI specifies one or more MIMO parameters; and
perform uplink MIMO communication with the base station according to the MIMO uplink configuration and the one or more MIMO parameters, wherein two port SRS resources and four port SRS resources are configured in a same SRS resource set, wherein said performing uplink MIMO communication comprises transmitting physical uplink shared channel (PUSCH) transmissions so that a first PUSCH transmission scheduled with four port SRS resources is transmitted in partialAndNonCoherent and a second PUSCH transmission scheduled with two port SRS resources is transmitted in NonCoherent.
