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 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.

Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be known as user equipment (UE), may be capable of full-duplex communications. The UE may determine that at least a portion of a downlink transmission that the UE may receive while concurrently scheduled to transmit an uplink transmission, may overlap with a clear channel assessment (CCA) procedure (e.g., a listen-before-talk (LBT) operation) in a shared radio frequency spectrum band. The UE may determine that at least a portion of the downlink transmission that overlaps with the LBT resources may be canceled or the downlink transmission may be rate matched and allocated to resources outside of the LBT resources. As a result, the UE may perform an LBT procedure without interference caused by the UE receiving the downlink transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a first frequency resource allocation associated with a first slot type and, in some cases, a second frequency resource allocation associated with a second slot type for a configured grant (CG). The CG may be associated with half-duplex (HD) slots and subband full-duplex (SBFD) slots. The UE may transmit an uplink message to a network entity via a first set of one or more slots associated with the CG using the first frequency allocation based on the first set of one or more slots being of the first slot type. The UE may cancel a use of the first frequency allocation for transmitting the PUSCH via a second set of one or more slots if the second set of slots is of the second slot type.

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.

Abstract: Certain aspects of the present disclosure provide techniques for enhancing sidelink resource utilization for a user equipment (UE) that supports full duplex (FD) communications. For example, an FD UE may receive incoming sidelink communication over a first set of resources and, in FD mode, simultaneously transmit another sidelink communication over the same first set of resources. According to aspects of the present disclosure, the potential interference between the two sidelink communications will be mitigated or reduced, such as by having the FD UE negotiate with other sidelink UEs over transmission power levels and related aspects, such as beam coordination and/or resource subset designation, or the like.

Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform or cancel an uplink transmission in a subband full duplex (SBFD) resource based on whether the indicated uplink beam is enabled or restricted for SBFD. A network entity may monitor for or refrain from monitoring for an uplink transmission in an SBFD resource based on whether the indicated uplink beam is enabled or restricted for SBFD. A UE may be configured with a first uplink beam for half-duplex uplink resources and a second uplink beam for SBFD resources. The UE may perform uplink transmissions scheduled in SBFD resources using the first uplink beam. A UE may use a single uplink beam configured for both half-duplex uplink resources and SBFD resources, or a single uplink beam may be configured and restricted from SBFD resources, and the UE may cancel a scheduled transmission in an SBFD resource.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may communicate on first and second carriers, and may support either two transmit chains or three transmit chains on a second carrier. A base station may configure different sounding reference signal (SRS) resources for different numbers of transmit chains. SRS resources configured with two ports may indicate two transmit chains, and SRS resource configured with three ports may indicate three transmit chains. The base station may indicate an index associated with an SRS resource, and the UE may select (e.g., based on a mapping between the SRS Configuration Information resource index and a number of SRS ports and a number of transmit chains), a corresponding SRS resource, number of ports, number of transmit chains, or any combination thereof. The base station may indicate a number of transmit chains for a given SRS resource based on a PMI index.
