Certain aspects of the present disclosure provide reference signal configurations including transmission power control offsets for multiple cells. In one example, a network entity obtains a reference signal configuration that comprises one or more transmission power control offsets for a first cell and one or more transmission power control offsets for a second cell.

Downlink power control in wireless communications

Methods, systems, and devices for wireless communications are described. Techniques described herein relate to schemes for managing an overlap of at least part of a tracking reference signal (TRS) with an uplink subband or a guard band in a subband full duplex (SBFD) slot or symbol. In some examples, if a user equipment (UE) and/or a network entity determines that at least a portion of a TRS is scheduled for reception in an uplink subband or a guard band of an SBFD slot or symbol, the UE and/or the network entity may: drop the TRS, puncture the portion of the TRS that overlaps with the uplink subband or the guard band; or may shift the frequency position of the TRS such that the TRS is scheduled within the downlink subband(s) of the SBFD slot or symbol.

Tracking reference signals in full duplex operation

Methods, systems, and devices for wireless communications are described for systems that use resource bandwidths within one or more bandwidth parts (BWPs). Such resource bandwidths may be configured in one or more BWPs to support relatively fast switching and allow enhanced flexibility for communications within a BWP. Within one or more BWPs, downlink reference signal resources of a first resource bandwidth may be associated with one or multiple uplink resources of a second resource bandwidth, and precoding for uplink communications in the one or multiple uplink resources may be calculated based on the associated downlink reference signal resources. Additionally or alternatively, abeam used for uplink communications may be provided to the UE in transmission control information (TCI). Further, in some cases, multiple disjoint subsets of uplink frequency resources within a resource bandwidth may use different beams, according to an indication provided in TCI.

Uplink reference signal techniques for non-codebook-based wireless communications

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

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical downlink control channel (PDCCH) linkage indication that is based at least in part on a slot configuration. The UE may receive a first PDCCH in a first PDCCH occasion and a second PDCCH that is a repetition of the first PDCCH in a second PDCCH occasion, the second PDCCH occasion comprising an occurrence of one or more air interface resources configured with the slot configuration. Numerous other aspects are described.

Physical downlink control channel linkage across different slots

Methods, systems, and devices for wireless communications are described. In one aspect, a UE may report channel state feedback (CSF) to a network entity based on channel state information (CSI) measurements and CLI measurements. In another aspect, a UE may explicitly report CLI measurements to a network entity. In yet another aspect, a UE may report a signal-to-interference-plus-noise ratio (SINR) to a network entity based on CLI measurements, and the network entity may trigger the UE to perform further CLI measurements on signals received from other UEs based on the SINR. In yet another aspect, a UE may generate a report using CLI measurements based on whether the UE is allocated enough time to generate and transmit the report. In yet another aspect, a UE may identify a suitable priority for reporting CLI to a network entity.

Prioritization and timing for cross-link interference reporting

A method for wireless communication by a user equipment (UE) includes receiving a configuration of a downlink bandwidth part (BWP). The method also includes receiving a frequency domain resource allocation (FDRA) in a slot. The FDRA includes a first type of bits corresponding to a downlink allocation within the downlink BWP and a second type of bits corresponding to either a known sequence or repeated bits. The method further includes communicating in accordance with the FDRA.

Scheduling downlink control information (DCI) in sub-band full-duplex (SBFD) slots

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.
