Abstract: Systems and methods for communication link adaptation and communication networks involving ground-based user equipment and non-terrestrial stations. A communication is received indicating signal quality of a first signal transmitted during a first transmission period and a plurality of fading losses associated with the first signal are obtained. A first fading loss and a second fading loss associated with the first signal are estimated for a future time, the first fading loss based on application of a first filter, and the second fading loss based on differences determined between the first fading loss and the plurality of fading losses. A signal-to-interference-plus-noise-ratio is calculated and includes at least one of the first fading loss and the second fading loss. A non-terrestrial station transmits, for a second time period, a second signal having settings determined based on the signal-to-interference-plus-noise-ratio.

In one novel aspect, TCI-state indication for non-coherent joint transmission (NCJT) channel station information (CSI) reporting is provided. The UE receives NCJT from at least a first transmission from a first transmission point (TRP) and a second transmission from a second TRP, determines a receiving (RX) spatial filter information for the NCJT and acquires channel state information (CSI) according to a report setting based on the determined RX spatial filter to simultaneously acquire at least two channel measurement resources (CMRs) and one interference measurement resource (IMR), wherein at least one CMR is from the first TRP and at least one CMR is from the second TRP. In one embodiment, the RX spatial filter information is determined based on a group-based beam reporting procedure performed by the UE. In another embodiment, the RX spatial filter information is determined based on TCI-state received from the wireless network.

Abstract: A hybrid class B channel state information (CSI) reference signal (CSI-RS) scheme is discussed which configures one cell-common beamformed CSI-RS resource for beam tracking and another UE-specific beamformed CSI-RS resource for CSI feedback. The cell-common beamformed CSI-RS resource may be transmitted at a longer periodicity and shared by user equipments (UEs) in the cell. The beamforming may be cycled over a set of predefined weights transparent to UE. The UE-specific beamformed CSI-RS may be transmitted at a shorter periodicity and can be activated dynamically to allow resource sharing among multiple UEs. The UEs will report a CSI for the cell-common beamformed CSI-RS resource which provides a quality indicator for the associated cell-common beam and is utilized by the base station to determine the precoding weight for the UE-specific beamformed CSI-RS resource. Both resources can be configured with different parameter sets, such as number of ports, codebook type, and CSI reporting parameters.

Abstract: In one aspect, this disclosure details methods and apparatuses for influencing the service continuity threshold used for switching a multimedia session between Packet-Switched (PS) transport and Circuit-Switched (CS) transport, in dependence on the “robustness” of the media configuration in use for the multimedia session. Robustness, for example, may be defined in terms of packet loss tolerance, and it will be understood that the media configurations available for a given multimedia session may have different levels of absolute or relative robustness and that the media configuration selected for use in a multimedia session may change during the multimedia session. Correspondingly, the approaches proposed herein provide mechanisms for dynamically adjusting the service continuity threshold in dependence on which media configuration is currently in use for the multimedia session.

Abstract: Generally, the described techniques provide for multiple input multiple output (MIMO) operation mode configuration (e.g., configuration of spatial MIMO, polarization MIMO, or both, across one or more antenna modules of a user equipment (UE)) based on the UE characteristics, channel characteristics, or both. For example, a UE may determine channel characteristics, as well as UE characteristics, for MIMO operation mode configuration. The UE may then feedback, to the base station, MIMO operation information (e.g., channel characteristics, UE characteristics, a request for one or more MIMO operation modes determined by the UE, or some combination thereof) for MIMO operation mode configuration. The base station may receive the MIMO operation information and may determine one or more MIMO operation modes for the UE based on the received MIMO operation information, network conditions, or both. The base station may then transmit a MIMO operation mode configuration to the UE.

Abstract: Described embodiments provide for low-latency classification of flows, via an intelligent learning-based system. In one implementation, a packet processor may utilize destination internet protocol (IP) addresses and domains identified in first packets of flows to determine if a similar flow has been previously received, directed to the same address and domain, or apply default routing and policy rules if not. The packet processor may subsequently fully classify the flow; generate a record in an association database for the combination of application, address, and domain, and a starting confidence level; and apply proper routing and policy rules. A subsequent flow for the same application and destination IP address may then be classified as the same as the prior flow, with corresponding routing and policy rules applied. The packet processor may continue to fully classify the flow, and upon full classification, the database entry may be updated and the confidence level adjusted.
