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.

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.

Techniques for successive tuning using a reconfigurable surface

Systems, methods, and devices for wireless communication that support mechanisms for uplink carrier selection for uplink random access channel (RACH) transmissions in a flexible cell configuration in a wireless communication system. A user equipment (UE) in a flexible cell selects at least one carrier for transmitting one or more uplink RACH transmissions to a base station. In aspects, the base station transmits an indication to the UE indicating which carrier the UE is to select for transmitting the one or more uplink RACH transmission. In aspects, the UE determines the carrier to transmit the one or more uplink RACH transmissions to the base station based on a comparison of reference signal measurements to predetermined thresholds. In these aspects, based on whether the measurements exceed the predetermined thresholds or not, the UE selects a carrier for transmitting the one or more uplink RACH transmission to the base station.

Uplink (UL) transmission in random access channel (RACH) on flexible cell

Various aspects of the present disclosure generally relate to configurations for new radio (NR) devices with reduced capabilities. In some aspects, a user equipment (UE) may determine a configuration from stored configuration information, where the configuration specifies a subset of features that NR UE with reduced capabilities is to support. The UE may communicate according to the configuration of reduced capabilities, or fall back to a set of further reduced UE capabilities. Numerous other aspects are provided.

Capability configurations for new radio redcap devices

Methods, systems, and devices for wireless communications are described. A base station that may include at least two transmission reception points (TRPs) next to a high speed train (HST) may transmit, to a user equipment (UE) on the HST, an indication of a quasi co-location (QCL) relationship indicating a relationship between a plurality of tracking reference signals (TRSs) and a demodulation reference signal (DMRS) of a data channel. The plurality of TRSs may include a first TRS and a second TRS. The UE may receive, from a first TRP, the first TRS associated with an occasion of the data channel, and receive, from a second TRP, the second TRS associated with the occasion of the data channel. The UE may perform, based on the indication of the QCL relationship, a channel estimation procedure for the data channel based on the DMRS, the received first TRS, and the received second TRS.

Quasi co-location type for doppler pre-compensated reference signal

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for performing initial access procedures including transmitting or receiving synchronization signal blocks (SSBs) based on a capability of a user equipment (UE) to use reconfigurable intelligent surfaces (RISs). In some examples, a base station may transmit SSBs using two synchronization raster grids. For example, the base station may transmit SSBs on a first synchronization raster grid for UEs that do not support RISs and on a second synchronization raster grid for UEs that support RISs. In some examples, a base station may transmit different types of SSBs. For example, a base station may transmit a first type of SSB for UEs that do not support RISs and a second type of SSB for UEs that support RISs. A UE may search for and receive SSBs according to a capability of the UE.

Transmitting synchronization signal block via reconfigurable intelligent surfaces

Methods, systems, and devices for wireless communications are described. A method for wireless communication may include receiving a single frequency networked composite reference signal (SFNed RS) at a first port of a user equipment (UE) and receiving a reference signal (RS) at a second port of the UE that is different than the first port of the UE. The method may also include performing channel estimation for at least one of the first port or the second port based at least in part on receiving the SFNed RS and the RS. A method for wireless communication may include transmitting a first portion of an SFNed RS from a first port of a first transmit/reception point to a UE and transmitting a downlink control information message to the UE that indicates at least one transmission configuration indicator state identifier that identifies the SFNed RS.

Consideration for demodulation reference signal and tracking reference signal quasi co-location relationship

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive a sounding reference signal (SRS) from a first user equipment (UE). The base station may receive a cross-link interference (CLI) report from a second UE based at least in part on the SRS. The base station may determine a CLI from an uplink shared channel based at least in part on a power headroom report for the uplink shared channel received from the first UE and the CLI report received from the second UE. Numerous other aspects are provided.
