The communication device includes: an antenna array configured to simultaneously form a first vertical beam and a second vertical beam for an arbitrary time; a transceiver configured to transmit and receive a signal using a double beam including the first vertical beam and the second vertical beam; and a processor configured to determine a first optimal vertical tilting angle of the first vertical beam based on Inter-Beam Interference (IBI) of the second vertical beam, and determine a second optimal vertical tilting angle of the second vertical beam based on the IBI of the first vertical beam.

An access node, method and computer program product for: receiving from a terminal device served by a first access node measurement data relating to a plurality of radio beams, determining that the measurement data comprises data relating to at least one radio beam provided by at least one second access node, receiving information relating to angular coverage of the at least one radio beam provided by at least the second access node, determining, based on the angular coverage and the measurement data relating to the plurality of radio beams, an estimated location of the terminal device, and selecting a set of radio beams for provision to the estimated location of the terminal device, wherein the set of radio beams comprises a subset of radio beams provided by the first access node for serving the terminal device.

A satellite having a set of antenna elements with predefined directions and beam angles is described. This satellite may dynamically select at least a given antenna element based at least in part on utilization and/or availability of a terrestrial wireless communication network used by an electronic device that communicates with the satellite. Moreover, the satellite may change its attitude based at least in part on the given antenna element, where the changed attitude positions a region in a predefined beam angle of the given antenna element. The satellite may dynamically select the region to which it transmits wireless signals. For example, the region may be selected based at least in part on weather conditions associated with the region and/or priority of content conveyed by the wireless signals. Alternatively, the satellite may receive information specifying the region, the utilization and/or the availability of the terrestrial wireless communication network in the region.

A method for reference signal processing is provided. In this example, the method includes receiving, by a UE, a message from a network device, where the message indicates both that a first reference signal is to be transmitted over a first resource and that a second reference signal is to be transmitted over a second resource. The method also includes receiving, by the UE, at least the first reference signal in accordance with capabilities of the UE and the message received from the network device.

A base station determines a temporal filter configuration for a user equipment (UE) and transmits the temporal filter configuration to the UE. The temporal filter configuration indicates whether the UE should apply a temporal filter to channel state information (CSI) measurements to generate CSI values, or identifies which temporal filter to apply. The UE generates CSI values based on the temporal filter configuration and reports the generated CSI values to the base station.
