Cross-Carrier Spatial Relation Indication for Semi-Persistent Sounding Reference Signal (SP-SRS) Resources

A method for a network node, in a wireless communication network, to activate or deactivate reference signal (RS) resources usable for management of transmit and/or receive beams for communication with a user equipment (UE), the method comprising:

• sending, to the UE, one or more control messages comprising configuration of a plurality of RS resources associated with a particular bandwidth part (BWP) of a particular component carrier (CC) in the wireless communication network;
• and
• sending, to the UE, a further control message comprising:
• identification of at least one RS resource, of the plurality of RS resources, to be activated or deactivated, and
• for each particular RS resource of the identified RS resources, an indication of the particular RS resource's spatial relation with a further resource that is not associated with the particular BWP of the particular CC.
