Power control for srs transmission used for non-codebook based ul transmission

Abstract

Method and apparatus for power control for SRS transmission used for non-codebook based UL transmission are disclosed. In one embodiment, a UE comprises a transceiver; and a processor coupled to the transceiver, wherein, a TCI state is indicated for a BWP of a serving cell, and wherein the processor is configured to determine, based on a PL-RS associated with the indicated TCI state for the BWP of the serving cell, RS index qd for obtaining the downlink pathloss estimate for SRS transmission corresponding to SRS resource set for non-codebook configured with an associated NZP CSI-RS resource; and obtain values of PO_SRS,f,c(qs), αSRS,b,f,c(qs), and SRS power control adjustment state 1 for the SRS transmission corresponding to the SRS resource set resource set for non-codebook configured with the associated NZP CSI-RS resource from a set of power control parameters for SRS including P0, alpha and closed loop index 1 in an uplink power control parameter set, wherein, the uplink power control parameter set is one of: (1) the uplink power control parameter set associated with the indicated TCI state; (2) a dedicated uplink power control parameter set configured for the BWP of the serving cell; and (3) an uplink power control parameter set in a uplink power control parameter set list configured for the serving cell with the lowest set ID.
