Methods and apparatuses for sounding reference signal configuration and triggering in a wireless communications network

The embodiment of the present disclosure relates to methods and apparatuses for sounding reference signal configuration and triggering in wireless communications network such as advanced 5G networks. A method performed by a user equipment (1300) comprising: receiving (901) a higher layer configuration that associates SRS resource, with a control resource set pool index which is a higher-layer parameter in a configuration of CORESET comprising resources on which a PDCCH is transmitted from a network node (1400) and deriving (902) a spatial relation or a reference signal as pathloss reference for said SRS resource with reference to at least one reference signal from quasi-colocation (QCL) information of a CORESET associated with the control resource set pool index; wherein the QCL information comprises a relationship between one or more reference signals and DMRS port(s) of the PDCCH transmitted on the CORESET and the relationship indicates parameter(s) that are obtained from the reference signals.
