Abstract: Methods, systems, and devices for wireless communications are described. A network entity may indicate whether a user equipment (UE) is to update an estimation of non-linear characteristics of a power amplifier of the network entity. The network entity may transmit, to the UE, control signaling and data signaling in a slot. The control signaling may indicate whether the UE is to update the estimation of the non-linear characteristics. If the control signaling indicates to update the estimation, the UE may perform a correction on pilot signals of the data channel to obtain an updated estimation, and the UE may decode the data signaling based on the updated estimation. If the control signaling does not indicate to update the estimation, the UE may decode the data signaling based on a previous estimation of the non-linear characteristics.

Abstract: Methods, systems, and devices for wireless communications using a singular value decomposition (SVD) combiner precoder are described. The described techniques may enable a network entity to determine which streams of a set of multiple data streams to combine in the SVD combiner precoder to increase a lowest signal-to-noise ratio of the set of multiple data streams, and which streams of the multiple streams to leave separate. The network entity may determine a precoding matrix using a square matrix α, which may allow the network entity to dynamically combine (e.g., or not combine) data streams. The network entity may transmit an indication to a UE indicating which streams the network entity will combine and which streams the network entity will not combine. The UE may accordingly demodulate the non-combined streams with a relatively less complex demodulator and may demodulate the combined streams with a relatively more complex demodulator.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may receive a first control message including an indication of a first beam from a plurality of beams from a user equipment (UE) for communicating with the UE. The network entity may receive one or more signals associated with an object that has a trajectory that is predicted to interfere with the first beam. Based on receiving the one or more signals, the network entity may determine that the object will block the first beam. The network entity may transmit a second control message to the UE indicating a time duration that the object will interfere with the first beam and one or more communication parameters associated with the time duration. The UE may apply the one or more communication parameters during the time duration based on receiving the signal from the network entity.

Abstract: An efficient scheme for suppression of base station NL is described. An apparatus is configured to provide, for a network node, an SNR indication for signals associated with the network node. The apparatus is configured to receive, from the network node, a NL indication based on the SNR indication, where the NL indication indicates an activation or deactivation of NL cancelation for the UE, and to demodulate data based on the NL indication. Another apparatus is configured to receive, from a UE, an SNR indication for signals associated with the network node. The apparatus is configured to provide, for the UE, a NL indication based on at least one of the SNR indication, a NL distortion level associated with the network node, or a thermal noise level associated with the network node, where the NL indication indicates an activation or deactivation of NL cancelation for the UE.

Abstract: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include transmitting, to a network node, information associated with a first quantity of effective downlink transmit (Tx) antennas associated with the UE. The example method may further include receiving, from the network node, a transmission indicative of a set of precoding functions for a set of Tx antennas associated with the network node, where each precoding function of the set of precoding functions is associated with a respective group of multiple Tx antennas of the set of Tx antennas associated with the network node, and where a second quantity of precoding functions is smaller than or equal to the first quantity of the effective downlink Tx antennas. The example method may further include receiving, from the network node, a second transmission based on the set of precoding functions.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a network entity. The method may include receiving an indication indicating a subset of one or more precoding matrix vectors associated with an estimated channel between a user equipment (UE) and the network entity. The subset of one or more precoding matrix vectors are part of a precoding matrix. The method may include calculating remaining precoding matrix vectors for the precoding matrix, based on the subset of one or more precoding matrix vectors. The method may include generating the precoding matrix based on the subset of one or more precoding matrix vectors and the remaining precoding matrix vectors. The method may include performing precoding of a downlink transmission based on the precoding matrix.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may obtain from a user equipment (UE), a report that indicates one or more signal quality values associated with a set of communication chains of the UE. The network entity may perform a frequency domain residual sideband (FDRSB) identification procedure to determine an FDRSB correction table associated with a set of frequency bands and the set of communication chains. The network entity may output to the UE a control message indicating the FDRSB correction table that identifies which one or more frequency bands of the set of frequency bands and which one or more communication chains of the set of communication chains are associated with FDRSB correction. The UE may demodulate one or more messages via at least one communication chain of the set of communication chains based on FDRSB correction performed using the FDRSB correction table.
