Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a translational or rotational misalignment between a first antenna array of the first wireless device and a second antenna array of a second wireless device that is in line-of-sight (LoS) wireless communication with the first wireless device via a channel. The first wireless device may update a channel matrix for the channel based on the translational or rotational misalignment, where the first wireless device may update the channel matrix with one or more beam steering metrics of the first antenna array so as to improve a beam alignment between the first antenna array and the second antenna array. The first wireless device may communicate with the second wireless device in accordance with the updated channel matrix.

Abstract: A method of wireless communication includes receiving, by a user equipment (UE) from a base station, a control message associated with a plurality of listen before talk (LBT) threshold values including a first LBT threshold value and a second LBT threshold value. The first LBT threshold value is associated with a first frequency spectrum, and the second LBT threshold value is associated with a second frequency spectrum different than the first frequency spectrum. The method further includes performing an LBT operation based on the first LBT threshold value and the second LBT threshold value. The method further includes, based on the LBT operation, performing a transmission by the UE using one or both of the first frequency spectrum or the second frequency spectrum.

Abstract: Aspects of the disclosure relate to downlink (DL) transmissions using various powers and assigning frequency resources based on the powers. An example base station may transmit, to a first user equipment (UE), an indication of a first transmit (Tx) power for one or more first DL transmissions to a first group of a plurality of groups. The first group may include the first UE. The first Tx power may have a first power level different from a second power level of a second Tx power for one or more second DL transmissions to a second group of the plurality of groups. Then, the base station may transmit, to the first UE, a first DL transmission of the one or more first DL transmissions using the first Tx power. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may modify the contents of a channel state information (CSI) report based on delaying transmission of the CSI report. For example, a base station may transmit one or more downlink messages to the UE from which the UE may generate CSI. The UE may delay transmitting a CSI report that includes the CSI report one or more times, for example, due to a collision between a semi-persistent scheduling (SPS) scheme and a time division duplexing (TDD) scheme according to which the UE and the base station communicate. Based on a quantity of occasions that the UE delays transmission of the CSI report, the UE may modify the CSI included in the CSI report and transmit the CSI report including the modified CSI to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, control information that indicates at least two transmission configuration indicator (TCI) states. A first TCI state of the at least two TCI states is associated with a half duplex mode of the UE, and a second TCI state of the at least two TCI states is associated with a full duplex mode of the UE. The UE may further receive, from the base station, a downlink transmission according to at least one of the first TCI state or the second TCI state. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described for cross-link interference (CLI) measurement and estimation in one or more cells that are inactive or dormant. A user equipment (UE) operating in a first serving cell (e.g., a primary cell (PCell)) may measure one or more reference signals, with the measurements used to estimate one or more CLI measurements of one or more other cells (e.g., one or more secondary cells (SCells)). CLI estimates may be based on scaling factors associated with frequency locations of the PCell and SCell, may be based on a coupling loss estimate associated with different frequency bands, or combinations thereof.

Abstract: Methods, systems, and devices for wireless communication are described to estimate interference for concurrent uplink and downlink communications based on an indication of one or more one or more characteristics of an interfering uplink signal communicated between a base station and a second user equipment (UE). The base station or the second UE may transmit, to a first UE, an indication of one or more characteristics of an uplink signal, such as a baseband of the uplink signal or one or more parameters of the uplink signal. The first UE may use the characteristic(s) of the uplink signal to estimate the baseband of the uplink signal and cancel interference associated with the uplink signal. For example, the first UE may use the baseband signal to estimate the interference and may subtract the estimated interference from a downlink signal received at the first UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a single downlink control information (DCI) message scheduling a simultaneous downlink transmission and uplink transmission in an unpaired band. In some aspects, the single DCI message may include a modulation and coding scheme (MCS) field having one or more bits that indicate a first MCS for the downlink transmission. The UE may determine a second MCS for the uplink transmission based at least in part on an offset from the first MCS for the downlink transmission. Numerous other aspects are provided.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms signaling non-linearities to a victim user equipment (UE) for interference cancellation in a wireless communication system. A victim UE may experience interference from an uplink transmission by an aggressor UE to a base station. The victim UE may obtain a power amplifier model associated with the aggressor UE. The power amplifier may include a non-linearity model of a power amplifier of the aggressor UE causing the interference on the victim UE. The power amplifier model obtained by the victim UE may be dependent on various parameters, such as a transmit power used by the aggressor UE to transmit the uplink transmission causing the interference. Based on the aggressor UE transmit power, the victim UE may select parameters for power amplifier model and may estimate the interference caused by the uplink transmission for interference cancellation.
