Methods, systems, and devices for wireless communications are described. A first wireless device such as a user equipment (UE) may receive a first message that indicates one or more resource allocation parameters associated with a bandwidth part (BWP). The one or more resource allocation parameters may include an indication of a first available resource block of the BWP, an indication of an effective size of the BWP, or both. The UE may then receive a second message that indicates a resource allocation for communicating with a network entity via the BWP during a transmission time interval (TTI). The UE may then communicate with the network entity during the transmission time interval in accordance with the resource allocation and based on applying the one or more resource allocation parameters.

Adaptation of a first available resource block and resource block group size for full-duplex communications

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, in a cell wake-up occasion associated with a network node that is operating in a power saving mode, a cell wake-up signal (C-WUS) that indicates a latency tolerance priority associated with the UE. The UE may communicate with the network node based at least in part on the network node transitioning from operating in the power saving mode to operating in an active mode. Numerous other aspects are described.

Delayed cell wake-up in response to a cell wake-up signal

Systems and techniques are provided for performing wireless communications. In some aspects, a use equipment (UE) may receive a crosslink interference (CLI) training session configuration from a network entity, wherein the CLI training session configuration corresponds to a CLI training session for a plurality of UEs including the UE. The UE may determine a CLI feedback information associated with performing the CLI training session and may transmit the CLI feedback information to the network entity. The CLI feedback information may be indicative of CLI between the UE and one or more additional UEs.

Distributed cross-link interference (CLI) management

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

Certain aspects of the present disclosure provide techniques for triggering aperiodic sounding reference signal (A-SRS) transmission across multiple uplink component carriers.

Flexible cross-carrier aperiodic sounding reference signal triggering enhancement

Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support resource restrictions for sub-band full duplex (SBFD) and dynamic time division duplex (TDD) operations. For example, a user equipment (UE) may receive, from a network entity, control signaling indicating a restriction to one or more slots associated with communications between the UE and the network entity. Each of the one or more slots may be associated with one or more sub-bands and the restriction may modify an availability of a duplexing setting for at least a portion of the one or more sub-bands. Additionally, the UE may communicate with the network entity via at least a subset of the one or more sub-bands of the one or more slots in accordance with the restriction.

Resource restrictions for sub-band full-duplex (SBFD) and dynamic time division duplex (TDD) operation

Methods related to wireless communication systems and transmission and/or reception of synchronization signal block (SSB) transmissions are provided. In some scenarios, communications may occur in one or more full-duplex slots. For example, a wireless communication device receives a synchronization signal block (SSB) transmission schedule. The SSB transmission schedule at least partially overlapping with an uplink (UL) frequency portion of a full-duplex slot. The wireless communication device receives one or more SSBs, where the one or more SSBs are received in at least a slot different than the full-duplex slot or in a DL frequency portion of the full-duplex slot. Other features are also claimed and described.

Synchronization signal block (SSB) in full-duplex

Certain aspects of the present disclosure provide a method of wireless communication at a user equipment (UE), generally including obtaining a signal indicating the UE should be awake for an upcoming discontinuous reception (DRX) ON duration; and monitoring for downlink control information (DCI) in the DRX ON duration, according to an indication in the signal of at least one periodicity of DCI monitoring occasions (MOs) for the DRX ON duration.

Wake-up signal indication of monitoring occasion distribution

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

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.

Doppler compensation capability signaling in wireless communications

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

Certain aspects of the present disclosure provide techniques for randomization of reconfigurable intelligent surface (RIS) signals. A method for wireless communication includes determining a random reflection parameter for each of one or more RISs. The random reflection parameter is random over time for the one or more RISs. The method includes applying random values of the random reflection parameter at different times at each of the one or more RISs.

Randomization of reconfigurable intelligent surface (RIS) signals

This disclosure provides methods, devices, and systems for full-duplex communications in wireless networks. Some implementations more specifically relate to multiple bandwidth parts (BWPs), active concurrently, for communications in a given direction (such as a downlink (DL) direction or an uplink (UL) direction) between a user equipment (UE) and a base station. For example, a first active BWP may be used for DL or UL communications in a half-duplex (HD) slot and a second active BWP may be used for DL or UL communications in an adjacent full-duplex (FD) slot. In some implementations, the UE may further change a status of one or more active BWPs after a given amount of time has elapsed. For example, the UE may change the states of an active BWP by deactivating the active BWP, switching the active BWP to a default BWP, or changing a role assigned to the active BWP.

Timer-based switching for multiple active bandwidth parts

Methods, systems, and devices for wireless communications are described. A device may receive a resource allocation for transmitting a transport block (TB) over a set of time slots. The TB may include a set of coded bits. In some aspects, the device may determine starting indexes of subsets of the coded bits, each subset of the coded bits may be for transmission during a respective subset of time slots. In some other aspects, the device may receive a configured grant for a transmission of the TB over the set of time slots. In other aspects, the device may scale a size of the TB based on a first value independent of a second value associated with a number of time slots associated with the set of time slots. The device may transmit the TB over the set of time slots based on one or more of the example aspects.
