A method includes communicating, between a first device and a second device, a scheduling control message indicative of first time-frequency resources for a first uplink reference signal transmission from the second device to the first device and further indicative of second time-frequency resources for a second uplink reference signal transmission from the second device to the first device. Wherein the first uplink reference signal transmission is associated with a receive beam having a first opening angle. Wherein the second uplink reference signal transmission is associated with a receive beam having a second opening angle. The first opening angle is smaller than the second opening angle. Furthermore the first uplink reference signal transmission is beam swept at the first device, and the second uplink reference signal transmission is not beam swept at the first device.
