Abstract: Aspects of the present disclosure provide a manner of associating a physical layer channel, such as, but not limited to, physical broadcast channel (PBCH), physical downlink control channel (PDCCH), and physical uplink control channel (PUCCH) and a receive beam assumption. The beam assumption may, for example, relate a receive beam direction with a reference signal transmitted by a base station in which the reference signal is used for any of multiple uses by a user equipment (UE), such as beam management, multiple BS, including terrestrial BS and/or non-terrestrial BS, and UE mobility.

Abstract: Mobility management in multi-tier wireless communication networks involves communicating signaling that includes tier activation information for controlling activation of a UE for operation with a network device of a first tier and a network device of a second tier. The multi-tier wireless communication network includes network devices distributed among multiple tiers, and the multiple tiers include a terrestrial tier and a non-terrestrial tier.

Abstract: Aspects of the present disclosure provide, in a system that uses multiple radio link types for different networks within the system, methods for selecting more than one radio link type for transmission and acknowledgement of a signal to overcome a problem of mismatch of RTT of signaling over the different radio link types. As a particular example, in an integrated system including both a terrestrial network (TN) portion and a non-terrestrial network (NTN) portion, after an original signal is transmitted over the NTN portion, acknowledgement of the original signal, and retransmissions as necessary, can be carried out over the NT portion.

Abstract: A communication system, a method, and one or more non-transitory computer-readable storage devices allowing joint a user equipment to perform initial access with terrestrial and non-terrestrial communication nodes of a service area. The service area is partitioned into terrestrial initial-access zones and non-terrestrial initial-access zones with each terrestrial initial-access zone associated with one or more of the terrestrial communication nodes and each non-terrestrial initial-access zone associated with at least one of the non-terrestrial communication nodes. The user equipment uses positioning reference signals from positioning anchors to determine its location, determine a zone from the terrestrial and non-terrestrial initial-access zones based on the location, select one of the terrestrial and non-terrestrial communication nodes based on the determined zone, and establishing communication with the selected communication node.

Abstract: Some embodiments of the present disclosure relate to mobility management across multiple subsystems of wireless network devices, such as base-stations, drones, balloons, planes and satellites. In particular, the maintenance of user experiences across the subsystems is addressed. Aspects of the present disclosure relate to integrating terrestrial networks with non-terrestrial networks and establishing mechanisms for managing mobility of user devices as the devices travel from a service area defined by a connection with a terrestrial network to a service area defined by a connection with a non-terrestrial network or vice versa. Aspects of the present disclosure relate to establishing a format for an exchange of communication between user devices and transmit-receive points so that the mobility of the user device may be appropriately managed.

Abstract: An integrated terrestrial/non-terrestrial network may allow for enhanced network coverage. However, there are control and management challenges associated with an integrated terrestrial/non-terrestrial network because the network and user equipments (UEs) are no longer confined to only using conventional cellular communication via terrestrial transmit-and-receive points (T-TRPs). One challenge is how to perform beam management. In some embodiments, methods and systems are disclosed in which an indication of angular direction (e.g. beam direction) is provided by the T-TRP. The indication of angular direction may be used by a UE for communicating with a non-terrestrial TRP (NT-TRP), e.g. using beamforming. However, the methods are not limited to integrated terrestrial/non-terrestrial networks or the involvement of NT-TRPs, but apply more generally to indicating angular direction for directional communication.
