Abstract: Techniques and apparatuses are described for determining a position of user equipment by using adaptive phase-changing devices. In aspects, a base station transmits wireless signals for a UE toward respective reconfigurable intelligent surfaces (RISs) of adaptive phase-changing devices. The APDs may direct reflections of the wireless signals in a direction, such as toward the UE, based on a configuration of the RIS of the APD. The base station receives, from the UE via a wireless connection, identifiers of the reflections of the wireless signals that are received by the UE. In some cases, the base station also receives a signal quality parameter associated with the reflection reaching the UE. The base station determines angular information based on the respective identifiers and/or signal quality parameters of the reflections. Based on the angular information and known positions of the APDs, the base station determines a position of the UE.

Abstract: Methods, devices, systems, and means for user equipment slicing assistance information by a user equipment, UE, are described herein. The UE detects a condition of the UE (610) and, based on the detecting, evaluating one or more preferences (612). Based on evaluating the one or more preferences, the UE sends UE Slicing Assistance Information, USAI, to a core network entity (614), the USAI being based on a current network slice configuration. The UE receives, from a base station, a reduced radio resource configuration for operating using the low-throughput network slice (616) and communicates using the low-throughput network slice (618).

Abstract: Techniques and apparatuses are described for user equipment-coordination set, UECS, hybrid automatic repeat request, HARQ, that establish a HARQ timeline that is specific to the capabilities of a respective UECS. Compared to a single user equipment, UE, the HARQ timeline for a UECS depends on a number of factors, such as the joint processing capability in the UECS, latency of communication over a local wireless network between the UEs in the UECS, or the like. Based on its capabilities, the UECS can request uplink and/or downlink processing delay times or a UECS-specific HARQ timeline from a base station. The base station grants the uplink and/or downlink processing delay times or the UECS-specific HARQ timeline to the UECS in a layer-1, layer-2, or a layer-3 control message. The use of a UECS-specific HARQ timeline increases the reliability of HARQ signaling for uplink and downlink communication between the UECS and a base station.

The method further includes preventing use of the traffic descriptor for application of a rule specifying route selection to the outgoing traffic (606).

Abstract: Techniques and apparatuses are described for deep neural network (DNN) processing for a user equipment-coordination set (UECS). A network entity selects (910) an end-to-end (E2E) machine-learning (ML) configuration that forms an E2E DNN for processing UECS communications. The network entity directs (915) each device of multiple devices participating in an UECS to form, using at least a portion of the E2E ML configuration, a respective sub-DNN of the E2E DNN that transfers the UECS communications through the E2E communication, where the multiple devices include at least one base station, a coordinating user equipment (UE), and at least one additional UE. The network entity receives (940) feedback associated with the UECS communications and identifies (945) an adjustment to the E2E ML configuration. The network entity then directs at least some of the multiple devices participating in an UECS to update the respective sub-DNN of the E2E DNN based on the adjustment.

Abstract: The techniques described in this disclosure enhance the reception of the information at a user equipment (UE) from an Active Coordination Set (ACS) of a wireless network system, where the ACS includes a set of base stations that jointly operate to communicate data between the system and the UE. The ACS allocates respective subsets of a plurality of time domain resources for use by corresponding ACS base stations in communicating with the UE, and provides, to the UE, an indication of the allocations. Based on the received allocation indication (502), the UE obtains data payload transmitted by the ACS (508) by tuning to various base stations in accordance with their respective time domain resource allocations (505). The ACS may redundantly transmit selected data payload and/or employ different encoding schemes to further enhance reception of information at the UE.

Abstract: Techniques and apparatuses are described for multiple-input multiple-output transmissions using adaptive phase-changing devices. In aspects, a base station selects one or more adaptive phase-changing devices, APDs, to use in at least one communication path for multiple-input, multiple-output, MIMO, transmissions. The base station can perform a channel characterization process for the at least one communication path using the at least one APD and at least one UE. Based on results of the channel characterization process, the base station configures the at least one APD by which to implement single user-MIMO communication with a UE or multiple user-MIMO communication with multiple UEs. By so doing, the base station may implement MIMO transmissions using APDs to communicate with the at least one UE using same time and frequency resources, which can improve spectral efficiency of a wireless network.

Abstract: A non-terrestrial, wireless communications network (NTN) can assist User Equipments (UEs) in tracking beams generated by NTN base stations for reselection purposes. The NTN determines one or more candidate beams to which the UE can reselect (e.g., while the UE is in an inactive or idle state with respect to controlling radio resources) based on a geographical location of the UE and respective existing and/or predicted non-terrestrial locations of one or more non-terrestrial base stations of the NTN. The NTN transmits an indication of the one or more candidate beams to the UE (and optionally other beam-related information, such as radio access resources and relative priorities), and the UE can reselect a subsequent beam based on the indication received from the NTN. The UE can locally store a mapping of candidate reselection beams to geographical locations for ease and efficiency of future reselections.

Abstract: A network entity transmits, to a first UE and a second UE, a plurality of reference signals via a plurality of beams corresponding to a plurality of subbands, receives, from the first UE, a first indicator of a first beam of the plurality of beams and a first subband of the plurality of subbands satisfying a first threshold, receives, from the second UE, a second indicator of the first beam and a second subband of the plurality of subbands satisfying a second threshold, the second subband being different from the first subband. The network entity further communicates, with the first UE in a slot, a first communication via the first beam and the first subband, and communicates, with the second UE in the slot, a second communication via the first beam and the second subband.

Abstract: This document describes techniques and apparatuses for a user equipment (UE)-coordination set for a wireless network. In aspects, a base station specifies a set of UEs to form a UE-coordination set for joint transmission and reception of data intended for a target UE within the UE-coordination set. The base station selects one of the UEs within the UE-coordination set to act as a coordinating UE for the UE-coordination set and transmits a request message that directs the coordinating UE to coordinate the joint transmission and reception of the data intended for the target UE. Then, the base station transmits a downlink signal to each UE within the UE-coordination set. Each UE within the UE-coordination set demodulates and samples the downlink signal and then forwards the samples to the coordinating UE, which combines the samples and processes the combined samples to provide decoded data.

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.

A master base station selects a first carrier subband associated with a first Active Coordination Set (ACS) for joint communication with a user equipment (UE), coordinates the joint communication for the UE with other base stations in the first ACS, and monitors the joint communication with the UE. Based on the monitoring of the joint communication, the master base station selects a second carrier subband that is associated with a second ACS for the joint communication with the UE and coordinates with base stations associated with the second ACS to jointly communicate with the UE using the second carrier subband.
