Claim 11:
12. A network node configured to operate in a wireless communication network and to activate semi-persistent sounding reference signal (SP-SRS) resources for transmission by a user equipment (UE), the network node comprising:
a radio network interface configured for communicating with one or more UEs; and
processing circuitry operatively coupled to the radio network interface, whereby the processing circuitry and the radio network interface are configured to:
send, to the UE, a radio resource control (RRC) message comprising configuration of a set of SP-SRS resources for UE transmission in a first serving cell of the wireless communication network; and
send, to the UE, 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
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.
