Abstract

The embodiments herein relate to a method performed by a network node and a network node. The method comprises setting a higher-layer parameter usage in at least one sounding reference signal, SRS, resource set configuration to nonCodebook or Codebook, wherein each configured SRS resource set comprises one or more SRS resources, and scheduling a physical uplink shared channel (PUSCH) transmission via a downlink control information (DCI) wherein at least two SRS resources are indicated via a sounding reference signal resource indicator (SRI) field of the DCI, wherein each SRS resource is associated with a different SRS resource set; and receiving from the user equipment a physical uplink shared channel that is transmitted using the ports associated with the indicated SRS resources.
