1. An apparatus for a user equipment (UE) configured for operation in a fifth-generation (5G) new radio (NR) network, the apparatus comprising: processing circuitry; and memory, the processing circuitry configured to:
decode a media access control Layer (MAC) control element (CE) (MAC CE) to activate a spatial relation info for a sounding reference signal (SRS) resource for two or more indicated component carriers (CCs);
apply the spatial relation info for the SRS resource for the two or more indicated CCs in response to the activation; and
when the spatial relation info is activated, configure the UE to transmit the SRS resource in the two or more of the indicated CCs with a same spatial transmission filter that is used for another reference signal configured in the spatial relation info when the UE is configured with one or more SRS resource configurations,
wherein transmission of the SRS resource in the two or more CCs comprises a joint beam transmission in accordance with carrier aggregation (CA) in a millimeter-wave frequency band (FR2), and
wherein the memory is configured to store the MAC CE.
