Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may communicate a signal using a first duplexing mode in accordance with a sub-band full-duplex (SBFD) capability of the UE. The UE may perform one or more measurements on the signal to obtain a channel impulse response (CIR) associated with communication of the signal. The UE may transmit a message that includes information indicative of an update pertaining to the SBFD capability of the UE. The update may be based on the channel impulse response and may identify a second duplexing mode for wireless communication by the UE.

Abstract: Methods, systems, and devices for wireless communications are described to indicate a single frequency network (SFN) mode and associated composite channel reference signals to a user equipment (UE). A UE and a base station may communicate via two or more transmission and reception points (TRPs) using an SFN transmission, which may represent a transmission having multiple beam configurations. The base station may transmit a configuration associated with a control channel that explicitly or implicitly indicates whether control channel transmissions are associated with an SFN mode or are configured with multiple candidate beam configurations. The base station may transmit an indication of activated beam configurations for the control channel. The UE may receive one or more reference signals from each TRP and, based on the SFN indication, may use information from the one or more reference signals to receive the control channel transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message indicating a wideband precoding configuration for wideband precoding of two or more downlink subbands for subband full-duplex (SBFD) communication. The UE may receive grants scheduling a physical downlink shared channel (PDSCH) via two or more downlink subbands within an SBFD resource (e.g., a slot). Accordingly, the UE may receive downlink data via the two or more downlink subbands. The UE may process the downlink data and transmit, via a feedback (e.g., uplink) resource, a feedback message acknowledging the downlink data, where a time period between the SBFD resource and the feedback resource is based on the wideband precoding configuration and the grant scheduling the PDSCH via the two or more downlink subbands.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicative of a semi-static time and frequency subband full-duplex (SBFD) configuration associated with at least one resource semi-statically configured as an SBFD resource, wherein the at least one resource comprises a time and frequency resource. The UE may receive a dynamic SBFD update indication associated with the at least one resource. The UE may perform a cross link interference (CLI) measurement task associated with an updated CLI resource based on the dynamic SBFD update indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to transmit one or more reference signals to a second wireless device using a first antenna array at the first wireless device and in accordance with a first precoder matrix. The first wireless device may receive, from the second wireless device based on the one or more reference signals, a feedback message indicating an estimated rotational misalignment, an estimated spatial misalignment, or both, between the first antenna array at the first wireless device and a second antenna array at the second wireless device. The first wireless device may then transmit a message to the second wireless device in accordance with a second precoder matrix that is modified relative to the first precoder matrix based at least in part on the estimated rotational misalignment, the estimated spatial misalignment, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sub-band full-duplex (SBFD) pattern indication that indicates an SBFD pattern for an SBFD resource. The UE may identify a time domain granularity and a frequency domain granularity for the SBFD resource based at least in part on the SBFD pattern indication. The UE may communicate via the SBFD resource in accordance with the time domain granularity and the frequency domain granularity. Numerous other aspects are described.

Abstract: Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a first wireless communication device includes receiving, from a second network entity, a first instance of information on a first sub-band of a bandwidth part and a second instance of the information on a second sub-band of the bandwidth part, wherein the first instance of the information and the second instance of the information fully overlap in time; and operating in a mode in which the first network entity makes use of the first instance of the information and the second instance of the information.

In some aspects, a user equipment (UE) may receive a downlink control information transmission comprising a resource allocation for downlink traffic and at least one dedicated table bit that indicates whether the UE is to use, to decode the downlink traffic, a first modulation order and a first target code rate corresponding to a first modulation and coding scheme (MCS) table or a second modulation order and a second target code rate corresponding to a second MCS table (a 1024 quadrature amplitude modulation table). The UE may decode the downlink traffic according to the first modulation order and the first target code rate or the second modulation order and the second target code rate based at least in part on at least one value of the at least one dedicated table bit.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message indicating a channel state information (CSI) reporting configuration for a subband full-duplex (SBFD) slot. The CSI reporting configuration may indicate that the UE is to report CSI for entire bandwidths of respective downlink subbands of the SBFD slot. That is, the CSI reporting configuration may configure the UE for per-downlink subband CSI reporting. The UE may receive CSI reference signals via the downlink subbands, and measure CSI for the reference signals. The UE may transmit, according to the CSI reporting configuration, a CSI report indicating the CSI for the downlink subbands. In some examples, the CSI may include some combination of channel quality indicators (CQIs) and precoding matrix indicators (PMIs).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may precode sounding reference signals using an interference covariance matrix to report channel quality information to a base station. For example, a UE may receive an indication of a future time from a base station. The future time may correspond to a future time for which the UE may predict an interference covariance matrix. In some cases, based on receiving the indication, the UE may monitor for interference in one or more interference measurement resources. In some examples, the UE may then determine the predicted interference covariance matrix and may transmit a sounding reference signal to the base station. The sounding reference signal may be precoded based on the predicted interference covariance matrix. In some cases, the UE may receive a downlink signal from the base station at the future time or at a second time.
