Abstract: Methods, systems, and devices for wireless communications are described. Specifically, techniques and signaling for configuring and utilizing parameters for unmanned aerial vehicle (UAV)-to-everything (U2X) communications are described, including registration procedures for U2X communications. A user equipment (UE), such as a UAV, may receive control signaling indicating a UE policy configuration including a set of radio parameters usable by the UE to perform sidelink communications to support one or more UAV services. The UE may receive an altitude limitation parameter associated with the one or more UAV services via the control signaling, additional control signaling, or both. The UE may then perform a sidelink message associated with the one or more UAV services in accordance with the UE policy configuration and altitude limitation parameter.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configuring associations between system information of at least one downlink (DL) anchor carrier and at least one random access channel (RACH) occasion (RO) of an uplink (UL) anchor carrier for initial access in flexible multicarrier operations. System information may be transmitted by a base station to a UE over the DL anchor carrier. In aspects, the at least one DL anchor carrier may be mapped to an UL anchor carrier, or to one or more candidate UL anchor carriers from which the UE may configurably select the UL anchor carrier, for initial access operations. In aspects, the UL anchor carrier and/or the one or more candidate UL anchor carriers may be respectively associated with one or more ROs. The UE may perform initial access operations over the UL anchor carrier using the associated one or more ROs.
