Abstract: When a user equipment (UE) is wirelessly communicating with a network, the wireless channel conditions may sometimes result in a low signal-to-noise ratio (SNR). The low SNR may be a result of the UE having poor geometry, e.g. the UE is at a cell edge. It is desired to increase the reliability of wireless communications in low SNR conditions. In some embodiments, less information may be dynamically signaled in the downlink control information (DCI), thereby allowing for a possibly lower effective coding rate.

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: In an integrated wireless communication network that includes terrestrial and non-terrestrial network devices, signaling that is indicative of information for application by a User Equipment (UE) in selection between multiple cooperation nodes to provide the UE with access to a non-terrestrial network device in the integrated wireless communication network is communicated. Cooperation may also or instead be applied in conjunction with a group handover procedure. For example, signaling that is indicative of information for application in making a handover determination by a cooperation node may be communicated. The handover determination may involve determining whether a first cooperation node is to perform a handover procedure to establish a connection to a second network device while a second cooperation node maintains its connection to a first network device; or the second cooperation node is to perform the handover procedure while the first cooperation node maintains its connection to the first network device.

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: Methods and devices utilizing sidelink transmission between user equipment (UEs) for HARQ retransmission are provided. The sidelink HARQ retransmissions include data from the initial transmission or an outer coded version thereof. HARQ feedback from the targeted receiver of the initial transmission may identify code block groups and/or individual code blocks the target receiver did not successfully decode. A UE that has not successfully decoded an entire transport block, may still cooperate in HARQ retransmission for the targeted receiver of the transport block by retransmitting at least a subset of the code block groups that it was able to successfully decode for the transport block.

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: 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.
