Methods and Apparatuses for Physical Uplink Shared Channel Beamforming and Pathloss Reference Indication in a Wireless Communications Network

A method performed by a user equipment (UE), the method comprising:

• receiving, from a network node, a higher layer configuration that associates a physical uplink shared channel (PUSCH) or a PUSCH grant with a control resource set pool index, wherein the control resource set pool index is a higher layer parameter in a configuration of at least one control resource set (CORESET), wherein the CORESET comprises resources on which a PDCCH is transmitted from the network node;
• and
• deriving at least one of a spatial relation and a pathloss reference signal (RS) for a PUSCH, with reference to at least one reference signal, from quasi-colocation (QCL) information of a CORESET, wherein the QCL information provides a relationship between one or more reference signals and demodulation reference signal (DMRS) ports of the PDCCHs transmitted on the CORESET, and the relationship indicates channel parameters or reception type parameters that are obtained from the reference signals.

A user equipment (UE) comprising a processor and a memory containing instructions executable by the processor, whereby said UE is operative to:

• receive, from a network node, a higher layer configuration that associates a physical uplink shared channel (PUSCH) or a PUSCH grant with a control resource set pool index, wherein the control resource set pool index is a higher layer parameter in a configuration of at least one control resource set (CORESET), wherein the CORESET comprises resources on which a PDCCH is transmitted from the network node;
• and
• derive at least one of a spatial relation and a pathloss reference signal (RS) for a PUSCH, with reference to at least one reference signal, from quasi-colocation (QCL) information of a CORESET, wherein the QCL information provides a relationship between one or more reference signals and demodulation reference signal (DMRS) port(s) of the PDCCH(s) transmitted on the CORESET, and the relationship indicates channel parameters or reception type parameters that are obtained from the reference signals.

A method performed by a network node, the method comprising:

• transmitting, to a user equipment (UE), a higher layer configuration that associates a physical uplink shared channel (PUSCH) or a PUSCH grant with a control resource set pool index, wherein the control resource set pool index is a higher layer parameter in a configuration of at least one control resource set (CORESET), wherein the CORESET comprises resources on which a PDCCH is transmitted from the network node, and
• receiving at least one PUSCH, from said UE, with at least one of a spatial relation and a pathloss reference signal (RS) derived by said UE, with reference to at least one reference signal, from quasi-colocation (QCL) information of a CORESET, wherein the QCL information provides a relationship between one or more reference signals and demodulation reference signal (DMRS) ports of the PDCCHs transmitted on the CORESET, and the relationship indicates channel parameters or reception type parameters that are obtained from the reference signals.
