Aspects of the present disclosure provide methods for
wireless communications. A UE can receive, from a
base station, a SRS configuration. The UE can have N antenna groups, N can be an integer greater than 2. The SRS configuration can indicate N SRS resources for the N antenna groups, respectively. Each of the N SRS resources can be associated with a SRI. SRSs can be transmitted from the N antenna groups using the N SRS resources, respectively. A DCI can be received from the
base station. The DCI can indicate two SRIs associated with two resources of the N SRS resources. The DCI can further indicate two TPMIs. A PUSCH can be transmitted using two antenna groups of the N antenna groups, which can correspond to the two SRIs indicated in the DCI, and two precoders, which can correspond to the two TPMIs indicated in the DCI. By utilizing the present disclosure,
wireless communications can be better.
