Abstract
The embodiment of the present disclosure relates to methods and apparatuses for PUSCH beamforming and pathloss reference indication in a wireless communications network. A method performed by a UE (900) comprises: receiving (301) from a network node, a PDCCH transmitted on a CORESET, wherein the PDCCH schedules at least one PUSCH, and deriving (302) a spatial relation and/or a pathloss reference RS, for the PUSCH(s), with reference to at least one reference signal, from quasi-colocation information of the CORESET; wherein the QCL information comprises a relationship between one or more reference signals and DMRS port(s) of the PDCCH, and the relationship indicates channel parameter(s) or reception type parameter(s) that are obtained from the reference signals. There is also provided a UE (900) and a network node (1000).
