Abstract: A method of operating a terminal having multiple antenna arrays includes, using the multiple antenna arrays: respectively monitoring and reporting on at least one downlink beam-sweeped transmission of pilot signals. The method also includes, based on a comparison of values indicative of a path loss of the pilot signals monitored using the multiple antenna arrays: selectively triggering adjustment of one or more values of at least one control parameter of said monitoring and reporting.

Abstract: 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.
