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.

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. 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.

Abstract: 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.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein support transmission of a transport block over multiple slots (TBoMS) with subband full duplex (SBFD) operation. For example, if a time domain resource allocation for a TBoMS includes both uplink slots and downlink slots configured with an uplink subband, a user equipment (UE) may determine which slots to use in accordance with a scheme for selecting available slots for the TBoMS from indicated candidate slots, and the UE may determine the transport block size based on the selected slots. In some examples, the UE may first determine the quantity of resource elements available in each of the different slot types, and then may determine the transport block size based on the quantity of resource elements available in each of the different slot types and the quantity of each of the different slot types.

Abstract: Methods, systems, and devices for wireless communication are described. A network entity may transmit, and a user equipment (UE) may receive, control signaling that configures or schedules sub-band full-duplex (SBFD) slots or symbols. The network entity may transmit, and the UE may receive, control signaling that schedules occasions, a resource block group, or a precoding resource block group that may overlap with the SBFD slot or symbols. The UE and the network entity may regulate communications based on application of one or more rules pertaining to communications when scheduled resource overlaps with a SBFD slot or symbol.

Abstract: A user equipment (UE) receives a configuration of a first plurality of subbands having different sizes for channel state information (CSI) reporting. The configuration is for a bandwidth part configured for subband full duplexing with an uplink subband. A size of the subbands in the first plurality of subbands decreases closer in frequency to the uplink subband. The UE transmit a reduced CSI report payload including a plurality of CSI values, the reduced CSI report payload having fewer bits than a size of an absolute CSI value times a number of subbands in the first plurality of subbands. The UE may reduce the number of bits in the CSI report payload using differential CSI values instead of absolute CSI values, reporting CSI values for only a subset of the subbands, or using a fallback subband configuration with equal sized subbands.
