Certain aspects relate to techniques for estimating and compensating for antenna array rotation of a wireless node. For example, the antenna array of the wireless node may rotate about one or more of an x-axis, a y-axis, and a z-axis, which may misalign the antenna array relative to another antenna array of another wireless node, causing degradation of communications between the two nodes. In some examples, the wireless node may obtain, from a first antenna array of the other wireless node via a second antenna array of the first wireless node, a first pilot signal and a second pilot signal via a first beam. In some examples, the first wireless node may perform a first alignment compensation based on a phase difference between the first pilot signal and the second pilot signal.

Estimating and compensating antenna array misalignment

A method, apparatus, and system for barring at least one UE from communicating with one or more RISs is disclosed. A base station may determine to bar at least one UE from communicating with one or more RISs of a plurality of RISs. The base station may transmit, to the at least one UE, a barring indication for the one or more RISs. The barring indication may identify the one or more RISs with which the at least one UE is barred from communicating. The UE may determine to refrain from communicating with the one or more RISs based on the barring indication. The UE may communicate with the base station based on the determination to refrain from communicating with the one or more RISs.

Contention-free RIS handover via barring

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a sub-band full-duplex (SBFD) configuration of a cell serving the UE. The SBFD configuration may indicate a first set of resources for downlink communications and a second set of resources for uplink communications. The first set of resources and the second set of resources may include non-overlapping frequency resources in a same time interval. The UE may receive a control message that indicates a pre-emption of the first set of resources or a cancellation of the second set of resources. Accordingly, the UE may determine that downlink transmissions in at least a portion of the first set of resources are pre-empted or that uplink transmissions in at least a portion of the second set of resources are cancelled based on the control message and the SBFD configuration of the cell.

Downlink pre-emption and uplink cancellation for full-duplex systems

Methods, systems, and devices for wireless communications are described. A transmitted may use a closed loop precoder for line-of-sight (LOS) multiple-input multiple-output (MIMO) communications that uses information such as distance feedback or LOS MIMO channel state feedback. A closed loop precoder may be associated with less overhead than a precoder based on full channel knowledge, such as an SVD precoder. A receiver may estimate a channel based on channel state information reference signals transmitted by the transmitter and calculate a spectral efficiency for one or more precoders of a set of precoders associated with the channel for a LOS MIMO mode. The receiver may send feedback to the transmitter that indicates a selected precoder of the set of LOS MIMO precoders based on the calculated spectral efficiencies. The transmitter may precode messages using the reported closed loop precoder.

Method and apparatus for codebook design for closed loop operation

Methods, systems, and devices for wireless communications are described that provide for a transmitter (e.g., a user equipment (UE) or base station) and receiver (e.g., a UE or base station) to transmit and receive data packets that are encoded according to an outer coding technique. The outer coding technique may provide for data bits and parity bits to be included in a single physical layer transmission. In some cases, data packets (e.g., data bits) may be segmented into multiple subpackets, and coding may be performed across different subpackets of different data packets (e.g., in a diagonal coding pattern). In some examples, each transmission in the physical layer may contain both data subpackets and parity subpackets, which may balance an input and an output load of a buffer (e.g., a layer two (L2) decoding buffer at the receiver) during decoding.

Outer coding techniques in wireless communications

Certain aspects of the present disclosure provide techniques for wireless communication by a first network entity of a first network of a first network operator. A method includes receiving, from a second network entity of a second network of a second network operator, frequency allocation information indicating a first allocation pattern identifying, for each of at least one cell, a corresponding frequency channel band of a frequency band spanning a plurality of frequency channel bands, wherein the first allocation pattern identifies a first frequency channel band of the plurality of frequency channel bands for a first cell of the at least one cell; and sending an indication to at least a first user equipment (UE) indicating to communicate in the first cell using a second frequency channel band of the plurality of frequency channel bands that is different than the first frequency channel band.

Spectrum sharing between networks

Data aware precoding techniques are disclosed. A transmitter may apply a precoder function to payload data to obtain a precoded data transmission. The precoder function may include a first portion, e.g., based on a channel measurement, and a second portion, e.g., based on data for transmission. The transmitter may transmit the precoded data transmission. A receiver may receive a precoded data transmission that is precoded based on a channel measurement and based on data comprised in the data transmission. The receiver may decode the precoded data transmission based on the channel measurement and the data comprised in the data transmission.

Data based precoding techniques

Methods, systems, and devices for wireless communications are described. The method includes selecting a first secure physical uplink channel and a second secure physical uplink channel for multiplexing based on the first secure physical uplink channel and second secure physical uplink channel overlapping, generating a secret key based on selecting the first secure physical uplink channel and the second secure physical uplink channel for multiplexing in accordance with the first secure physical uplink channel overlapping the second secure physical uplink channel in time, generating multiplexed information based on multiplexing the first secure physical uplink channel and the second secure physical uplink channel, and encrypting the multiplexed information based on the secret key.

Multiplexing secure physical uplink channels

In some implementations, a current synchronization reference anchor for the group of RF positioning anchors may obtain metric information from each radio frequency (RF) positioning anchor of the group of RF positioning anchors. The current synchronization reference anchor may select the new synchronization reference anchor from the group of RF positioning anchors based at least in part on the metric information.

Distributed time synchronization for time difference of arrival (TDOA) using ultra-wideband (UWB)

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request for sets of neural network weights, each set corresponding to a neural network, to one or more network entities. The one or more network entities may transmit multiple sets of neural network weights to the UE in response to the request. The UE may run a classifier neural network on the sets of neural network weights to select a set of neural network weights corresponding to a neural network. The UE may transmit a neural network identifier to the one or more network entities that transmitted neural network weights.

Online training and augmentation of neural networks for channel state feedback

Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for determining a beamformer to apply to groups of two or more elements of a reconfigurable intelligent surface (RIS). The beamformer is applied to the groups of elements of the RIS to facilitate communications at the operating frequency by re-radiating radio signals via the elements of the RIS. For example, by grouping RIS elements in different manners and applying a beamformer (e.g., precoding weights) to the group as if the group were a single RIS element, the RIS can be reconfigured to behave differently to suit various operating frequencies of the radio signals.

Reformulating reconfigurable intelligent surface (RIS) elements based on operation frequency

A UE may receive an indication of a first assignment of a first PDSCH via a PBCH from a network entity. The first PDSCH may include at least a first portion of a SIB. The UE may receive the first portion of the SIB via the first PDSCH from the network entity based on the first assignment of the first PDSCH. The first portion of the SIB may include access control information for the network entity and the assignment for a second portion of the SIB. The UE may identify whether the UE is permitted to access the network entity based on the access control information for the network entity.

Structure of minimum SI

Certain aspects of the present disclosure provide a method for wireless communications by a user equipment (UE) generally including transmitting, to a network entity, capability information indicating a capability of the UE for uplink subband filtering, receiving signaling scheduling an uplink transmission from the UE in a subband full duplex (SBFD) slot on resources determined based on the indicated capability, and transmitting the uplink transmission in the SBFD slot with uplink subband filtering, in accordance with the scheduling.

Enhanced uplink emission capability for subband full duplex

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently reporting channel state information (CSI) with limited overhead. In one aspect, if a user equipment (UE) is configured to transmit data and CSI to a base station periodically, the UE may transmit the CSI when the UE has data to transmit to the base station. In particular, the UE may transmit data and a CSI report during a transmission opportunity if the UE has data to transmit in the transmission opportunity. Otherwise, the UE may suppress transmission of the CSI report. In another aspect, a UE may be configured to transmit CSI to a base station when downlink channel conditions change. In particular, the UE may request to report CSI to the base station when channel conditions change, and the base station may trigger the UE to report the CSI after receiving the request.

Channel state information triggering for uplink dominant traffic

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to transmit, to a base station via a reconfigurable surface at a first transmission occasion, a first reference signal associated with a first reflection matrix configuration used by the reconfigurable surface to reflect signals, the first reflection matrix configuration included within a set of reflection matrix configurations. The UE may then transmit, to the base station via the reconfigurable surface at a second transmission occasion, a second reference signal associated with a second reflection matrix configuration used by the reconfigurable surface to reflect signals, the second reflection matrix configuration included within the set of reflection matrix configurations. The may then communicate with the base station via the reconfigurable surface based on transmitting the first reference signal, the second reference signal, or both.
