This disclosure provides systems, methods, apparatus, computer programs encoded on computer readable-medium to provide a user equipment (UE) to receive a reference signal from a base station, wherein the reference signal is received within a frequency-time region that overlaps with a control channel frequency-time region, generate information related to a control channel between the UE and the base station based on the reference signal, and transmitting the information to the base station.

Channel state information (CSI) feedback for physical downlink control channel (PDCCH)

Methods, systems, and devices for connection setup in an orbital angular momentum (OAM)-based communication system are described. A first device and a second device may establish an OAM communications connection between the devices. The first device and the second device may exchange a series of messages over a downlink communications link and an uplink communications link according to an OAM mode. Based on OAM related parameters or OAM related information included in the messages, the first device and the second device may achieve a successful directional alignment (co-axial alignment) between the first device and the second device. The first device and the second device may determine one or more orbital angular momentum modes for communication between the first device and the second device based on the establishing the directional alignment.

Connection setup in OAM-based communication system

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a transmission configuration state for receiving downlink channel transmissions from a base station via a configurable surface. The transmission configuration state may indicate a quasi-co-location source associated with transmission via the configurable surface. The UE may receive a downlink channel transmission via the configurable surface based on the transmission configuration state and the quasi-co-location source. The UE may be capable of determining whether the transmission configuration state conflicts with the quasi-co-location source indicated by the transmission configuration state. The UE may transmit an indication to the base station that the configuration for the transmission configuration state conflicts with the quasi-co-location source. The indication may include a beam failure indication or a measurement report. The UE may fall back to a transmission configuration state previously activated at the UE.

Downlink transmission configuration for reconfigurable intelligent surfaces

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive first control signaling indicating a first network operation sequence associated with a first component carrier, the first network operation sequence including a first set of time intervals corresponding to a first set of network operation modes for the first component carrier. The UE may additionally receive second control signaling indicating a second network operation sequence associated with a second component carrier, the second network operation sequence including a second set of time intervals corresponding to a second set of network operation modes for the second component carrier. The UE may then communicate via the first component carrier in accordance with the first network operation sequence, and communicate via the second component carrier in accordance with the second network operation sequence.

Techniques for network energy saving sequences and cell interaction

Certain aspects of the present disclosure provide techniques for channel state information (CSI) for multiple transmission reception point (mTRP) scenarios. The techniques may provide for dynamic interference measurement for mTRP CSI. A method that may be performed by a user equipment (UE) includes receiving a CSI reporting configuration configuring the UE with a plurality of CSI reference signal (CSI-RS) resources for channel measurement (CMRs) and a plurality of resources for interference measurement (IMRs). The method includes determining an indicator based on an association between one or more CMRs and one or more IMRs. A codepoint of the indicator is associated with an IMR or a set of IMRs by an order of the IMRs or the set of IMRs in the configuration, and is associated with a CMR, a CMR pair, or a part of the ports of a CMR. The method generally includes performing CSI measurement based on the association.

Dynamic interference measurement for multiple-TRP CSI

Channel state information-reference signal (CSI-RS) resources are disclosed with multiple transmission configuration indication (TCI) states. Example aspects of the present disclosure provide for indications that a given CSI-RS resource is associated with multiple TCI states within various configuration control signaling, depending on whether the CSI-RS is periodic, semi-persistent, or aperiodic. Additionally, where any trigger state corresponds to a CSI-RS resource set in which one or more CSI-RS resources are associated with multiple TCI states, one or more quasi-co-location (QCL) assumptions of the downlink transmission may also be applied by a user equipment (UE) to reception of the CSI-RS resources, where the scheduling offset is less than the threshold beam switch timing reported by the UE.

Channel state information-reference signal resources with multiple transmission configuration indication states

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, information that indicates a periodic sequence of network energy saving (NES) states that are each associated with an antenna configuration of the network node. The UE may receive, from the network node during a current time period, one or more downlink transmissions using a maximum quantity of multiple input multiple output (MIMO) layers associated with an active NES state that is identified for a current time period based at least in part on the periodic sequence of NES states. Additionally or alternatively, the UE may transmit, to the network node during the current time period, one or more sounding reference signal (SRS) transmissions using an SRS antenna sounding configuration associated with the active NES state for the current time period. Numerous other aspects are provided.

Joint antenna adaptation in energy saving networks

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

Methods, systems, and devices for wireless communications are described. In some systems, a device may select antenna elements from a planar array to transmit or receive an orbital angular momentum (OAM) beam. The device may determine a first area (e.g., a first ring area) based on an angular direction over which the device can communicate an OAM beam with a second device and may determine a second area (e.g., a second ring area) on the planar array based on projecting the first area on the planar array. The device may select a set of antenna elements from the planar array that are located within the second area. The device may determine a complex-valued weight for each antenna element of the selected set of antenna elements and may transmit or receive an OAM beam to or from the second device via the set of antenna elements according to the angular direction.

Generating and steering orbital angular momentum beams

Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may be configured to transmit data to a network device using an unencoded signal that includes parameters for updating a local data model. The UE may receive a radio network temporary identifier (RNTI) to decode a resource allocation message that schedules uplink resources for the transmission of the parameters, where the RNTI may be a dedicated RNTI that is different from other RNTIs received by the UE. The UE may identify allocated resources as scheduled by the resource allocation message, and may apply analog modulation and pre-equalization parameters to a data block to form an unencoded uplink transmission that includes the model parameters. The UE may transmit the unencoded uplink message in accordance with an over-the-air computation procedure.

Resource allocation for over-the-air model aggregation in federated learning

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a channel state information (CSI) report configuration that includes configuration information associated with multiple CSI reports. The UE may generate a CSI report message in which the multiple CSI reports are separately encoded and ordered based at least in part on one or more rules. In some aspects, the CSI report message may be generated for transmission on one or more of a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH). Numerous other aspects are provided.

CSI report configuration with multiple CSI reports

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first channel state information (CSI) for a first group of antennas of the UE and a second CSI for a second group of antennas of the UE, where the first group of antennas are different than the second group of antennas. The UE may transmit one or more of the first CSI or the second CSI in a CSI report. Numerous other aspects are provided.

Channel state information feedback for multiple antennas

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more of an input size or an input structure for a transmitting-side neural network, wherein the input structure indicates one or more of non-zero values or locations for the non-zero values within an input, having the input size, to the transmitting-side neural network. The UE may communicate with a base station based at least in part on the indication of the one or more of the input size or the input structure of the transmitting-side neural network. Numerous other aspects are provided.

Communications using a neural network based at least in part on an indicated input size and/or input structure

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 communications are described in which user equipment (UE) may provide a capability indication to one or multiple transmission reception points (TRPs) that indicates whether the UE is capable of performing Doppler pre-compensation. One or more of the TRPs may transmit configuration information to the UE to configure Doppler pre-compensation for subsequent communications. The UE may indicate that multiple Doppler shifts for a single communication with multiple TRPs is supported, or that a single Doppler shift or no Doppler shift is supported. The UE, when Doppler pre-compensation is supported and configured, may estimate one or more Doppler metrics (e.g., a Doppler shift, a maximum Doppler spread, or both) for one or multiple TRPs based on one or more reference signals from the TRPs, and may transmit one or more uplink communications based on the estimated Doppler metrics.
