Claim 6:
7. A method for a user equipment (UE) to transmit a semi-persistent sounding reference signal (SP-SRS) resource to a network node in a wireless communication network, the method comprising:
receiving, from the network node, a radio resource control (RRC) message comprising a configuration of a set of SP-SRS resources for transmission in a first serving cell of the wireless communication network;
receiving, from the network node, a medium access control (MAC) control element (CE) message for activating the configured set of SP-SRS resources, the MAC CE message comprising:
information identifying an SP-SRS resource of the set of SP-SRS resources to be activated, and the method being characterized in that the MAC CE message comprises:
an indication of the identified SP-SRS resource's spatial relation with a further resource on a second serving cell different from the first serving cell, wherein the indication comprises an identifier of the further resource and an identifier of the second serving cell; and

transmitting the identified SP-SRS resource using a same spatial domain filter as used to receive or transmit the further resource.
