Abstract: Techniques and apparatuses are described for radio access technology identifiers. In aspects, a base station receives air interface resource prospective usage information associated with communications over a first wireless link of at least two wireless links that use different Radio Access Technologies (RATs). The base station then allocates the sharable air interface resource between the at least two wireless links by analyzing the air interface resource prospective usage information. In aspects, the base station transmits a RAT-identifier-presence indicator that communicates a presence of a RAT identifier by indicating one or more downlink air interface resources used to transmit the RAT identifier, where the RAT identifier indicates the allocation of the sharable air interface resource between the at least two wireless links. The base station then transmits the RAT identifier using the one or more downlink air interface resources indicated by the RAT-identifier-presence indicator.

Abstract: Techniques for improving, for a set of conditions at a UE, the usage of energy stored at a UE include determining a preferred or requested partitioning of the UE's stored energy usage during wireless data transfer between the UE and the base station (e.g., an amount or percentage of stored energy utilized by the UE for baseband signal processing with respect to the amount or percentage of energy utilized by the UE for radio interface signal processing tasks), and indicating the preferred partitioning to the base station or network. Based on the indication, the base station/network may modify the baseband communication scheme, parameters, and/or values, and/or the radio interface communication scheme, parameters, and/or values utilized for the wireless transfers of data between the base station and the UE, thereby better managing (and in some cases, optimizing) the UE's stored energy usage and increasing battery life at the UE.

Abstract: A receiver receives signals from a transmitter in subframes on subcarriers having orthogonal frequencies. A subset of the subframes include reference signals. The receiver generates a first channel estimate for a target subframe based on reference signals in the target subframe. The receiver also generates one or more second channel estimates for one or more other subframes based on one or reference signals in the other subframes. The receiver combines the first channel estimate and the one or more second channel estimates based on a frequency offset between the receiver and the transmitter to form a channel estimate of the target subframe. In some cases, the receiver performs joint estimates of a timing offset, a frequency offset, and a channel for the target subframe based on the reference signals, selected candidate timing offsets, selected candidate frequency offsets, and selected candidate channel estimates.

Abstract: A user equipment (UE) reduces power consumption by selectively disconnecting from a radio access network (RAN) while in a non-standalone (NSA) mode in response to detecting a threshold number of communication failures associated with the RAN. The UE connects to a core network in the NSA mode via both a 4G RAN and a 5G RAN. The UE monitors the connection with the 5G RAN for communication failures, such as Random Access Channel (RACH) failures, radio link failures (RLFs), and the like. In response to the number of detected failures exceeding a threshold, the UE can determine that the quality of the connection with the 5G RAN is providing relatively little benefit and can terminate the connection with the 5G RAN.

Abstract: Two devices in wireless communication implement a soft transmission feedback scheme. A data-sending device wirelessly communicates a first transmission representing a data block and generated using one or more neural networks to a data-receiving device, which processes the first transmission using one or more neural networks to attempt to recover the data block, as well as to generate transmission feedback indicating a status of the recovery attempt. The feedback is used by one or more neural networks to generate a second transmission that is wirelessly communicated to the data-sending device. One or more neural networks process the second transmission to generate a retransmit control signal. One or more neural networks selectively include at least a portion of the data block for retransmission in a third transmission to the data-receiving device based on the retransmit control signal.

Abstract: Techniques and apparatuses are described for adapting an end-to-end, E2E, machine-learning, ML, configuration for processing communications transferred through an E2E communication. A network entity directs a user equipment (UE) and a base station participating in the E2E communication to implement the E2E communication by forming at least a portion of an E2E deep neural network, DNN, based on a first E2E ML configuration. The network entity determines to update the first E2E ML configuration based on a change in a participation mode of an edge compute server (ECS) in the E2E communication. The network entity identifies a second E2E ML configuration based on the change in participation mode and directs the UE or the base station to update the portion of the E2E DNN using the second E2E ML configuration.

Abstract: Access class barring can provide latency for accessing a barred service using a radio access technology (RAT) due to congestion of a local cell accessed via that RAT. A user equipment (UE) supports multiple RATs and the same service may be accessible via a separate cell accessed using a different RAT. Various aspects of the present disclosure describe techniques for configuring the UE to selectively switch between RATs to access a service based on a barring factor employed for a particular RAT, thereby reducing latency for accessing the service. The UEs may operate to monitor a current value of a barring factor for a service the UE seeks to access via a preferred, or default, RAT. In the event that the current value of the barring factor exceeds a specified threshold, the UE switches over to using a different RAT to access this service.

Abstract: This document describes techniques for flexible frequency band pairing for satellite communications. In aspects, a non-terrestrial communication system uses multiple frequency bands for a wireless link between a user equipment, UE, and a satellite of the non-terrestrial communication system. The non-terrestrial communication system determines to utilize two different frequency bands the wireless link between the satellite and the UE, the two different frequency bands being defined by a governing entity. In response, the non-terrestrial based communication system selects a first defined frequency band for downlink communications from the satellite to the UE and a second defined frequency band for uplink communications from the UE to the satellite. The non-terrestrial communication system then directs the satellite and the UE to communicate via the wireless link by using the first defined frequency band for the downlink communications and the second defined frequency band for the uplink communications.

Based on identifying the first base station using the APD, the second base station obtains apportioned access to the APD and configures a surface of the APD based on the apportioned access. The second base station uses the APD in a communication path for the second wireless link with the second UE based on the apportioned access.
