1. A method performed by a wireless communication device comprising:
receiving, from a network node, a configuration of a first Sounding Reference Signal, SRS, resource set to be used for non-codebook based Physical Uplink Shared Channel, PUSCH, transmission and a second SRS resource set to be used for non-codebook based PUSCH transmission;
receiving, from the network node, a configuration of a first Non-Zero Power, NZP, Channel State Information Reference Signal, CSI-RS, associated with the first SRS resource set and a second NZP CSI-RS associated with the second SRS resource set;
receiving a request for transmitting data in PUSCH in a plurality of occasions, wherein the request comprises:
an indication that data transmission in PUSCH in the plurality of occasions is based on both the first SRS resource set and the second SRS resource set;
a first SRS resource indicator, SRI, associated with the first SRS resource set; and
a second SRI associated with the second SRS resource set; and
transmitting a first PUSCH in a first set of occasions according to the first SRI and a second PUSCH in a second set of occasions according to the second SRI, wherein the first PUSCH comprises a first SRS according to the first SRI and the second PUSCH comprises a second SRS according to the second SRI.
