A beam pattern of a base station antenna is refined when communicating with multiple aircraft, so that interference to adjacent beams from the base station are reduced. The method include receiving position locations from each of multiple aircraft. The method also include the receipt of an attitude of each of the aircraft as well as receipt of measurements of the pilot signals from each of the aircraft. The pilot signals were transmitted by the base station. The method also include the adjustment of an amplitude and a phase of a signal driving at least one antenna transmit element to refine the beam pattern. The adjustment is based at least in part on the pilot measurements, the position locations, and the attitude of each of the aircraft.

Signaling for conditional primary secondary cell addition/change configuration

Aspects relate to wireless communication where a master node (MN) or a secondary node (SN) may initiate a conditional addition of a primary secondary cell (PSCell) or a conditional change from one PSCell to another PSCell. Each candidate target PSCell may provide information to be used by the MN to generate a conditional PSCell addition (CPA) configuration or a conditional PSCell change (CPC) configuration that is sent to a user equipment (UE). This information may indicate an execution condition for each candidate target PSCell and/or radio bearers that each candidate target PSCell supports or does not support. An MN may modify a master cell group (MCG) configuration for a PSCell based on information received from a target SN with an secondary cell group (SCG) configuration for the PSCell. The MN may transmit a CPA or CPC configuration including the modified MCG configuration and the SCG configuration to the UE.

Multicast handover for mobile communications

Embodiments provide efficient multicast handover for content delivery to client devices in multi-carrier communications systems. For example, client devices in a transport craft can consume a media channel offering via a first carrier during transport through the communications system. Embodiments can establish respective multicast groups for the media channel offering in at least the first carrier and a subsequent second carrier, and can notify the craft of the multicast groups prior to the craft being serviced by the second carrier. Such pre-notification can permit multicast handover of the media channel offering from the first carrier to the second carrier in a manner that avoids typical handover-related. For example, embodiments can direct multicast delivery of the media channel offering to the craft in accordance with the first multicast group while being serviced by the first carrier and in accordance with the second multicast group while being serviced by the second.
