Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, the described techniques provide for identifying interference signals on multiple layers or resources and determining whether the interference signals transmitted on a particular layer or resource were precoded using linear precoding (LP) or NLP. In this aspect, a receiving device may equalize signals received from a transmitting device (e.g., filter out interference signals) based on determining whether the interference signals were precoded using a first type of precoding (e.g., linear precoding (LP)) or a second type of precoding (e.g., NLP). In another aspect, the described techniques provide for performing interference measurements on signals precoded using NLP based on categorizing interference resources as being precoded using LP or NLP. In this aspect, a receiving device may perform and report measurements differently for interference signals precoded using LP and interference signals precoded using NLP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive an indication of a first transmit power configuration and a second transmit power configuration for a physical uplink shared channel (PUSCH) communication. The wireless communication device may transmit, using a first transmit power that is based at least in part on the first transmit power configuration, a first portion of the PUSCH communication in a full-duplex portion of a time-frequency resource. The wireless communication device may transmit, using a second transmit power that is based at least in part on the second transmit power configuration, a second portion of the PUSCH communication in a non-full-duplex portion of the time-frequency resource. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a network entity. For example, the network entity defines a size of reconfigurable intelligent surface (RIS) elements. The network entity further defines a set of patterns representing active RIS elements and/or inactive RIS elements, based on the size of RIS elements. The network entity transmits an indication of the size of RIS elements and the set of patterns to a RIS controller.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein may enable transmission power control (TPC) for user equipments (UEs) supporting reconfigurable intelligent surfaces (RISs). For example, a first UE may receive a control message indicating multiple parameter sets associated with calculating a transmission power for a transmission. Each parameter set may be associated with a communication link, a presence of one or more RISs, and whether the one or more RISs are assisting the first UE or a second UE. The UE may transmit signaling in accordance with a calculated transmission power based on selecting a first parameter set from the multiple parameter sets, where the first parameter set is selected based on a communication link associated with the transmission, a presence of one or more RISs during the transmission, and whether the one or more RISs are assisting the first UE or the second UE.

Abstract: A method of wireless communication by a user equipment (UE), includes estimating a downlink channel to generate a channel estimate. The method also includes obtaining multiple precoding matrices, by a channel state information (CSI) module including a neural network encoder decoder pair, based on the channel estimate and multiple different multiple input multiple output (MIMO) ranks. The method further includes determining a best rank indicator based on the precoding matrices and spectral efficiency estimates for the different MIMO ranks. The method still further includes reporting, to a base station, the best rank indicator, a channel quality index (CQI), and CSI encoder output.

Abstract: A user equipment (UE) may identify at least one suitable configuration for sounding reference signal (SRS) antenna switching and transmit the at least one suitable configuration for SRS antenna switching to the base station via a medium access control (MAC) control element (CE) (MAC-CE) or a radio resource control (RRC) message. The base station may receive the at least one suitable configuration for SRS antenna switching from the UE, and transmit an active SRS antenna switching configuration to the UE, the active SRS antenna switching configuration based on the suitable configuration for SRS antenna switching received from the UE.

Abstract: A method for wireless communication by a user equipment (UE), includes receiving, from a base station, a reference signal (RS) on a set of resource elements (REs), the RS having been multiplexed onto the set of REs based on a non-orthogonal cover code, and a number of REs in the set of REs being less than a number of ports associated with the RS. The method further includes estimating, at the UE via a channel estimation neural network, a channel based on receiving the RS. The method still further includes transmitting, to the base station, a feedback report associated with the estimated channel based on receiving the RS.

Abstract: A base station may identify a first antenna configuration of the base station and a second antenna configuration of a wireless device. The base station may select one or more codebook-based precoders for communication with the wireless device with LOS MIMO. The one or more codebook-based precoders may include at least one of a Legendre precoder, a block-DFT precoder, a DFT precoder, a block-Walsh precoder, a Walsh precoder, a block-Legendre precoder, a Kronecker Legendre precoder, a Kronecker block-DFT precoder, or a Kronecker block-Walsh precoder. The base station may transmit, to a wireless device, an indication of a second codebook-based precoder for transmission from the wireless device to the base station with LOS MIMO. The base station and the wireless device may communicate with each other with LOS MIMO based on one or more codebook-based precoders.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support compression of channel information (e.g., channel feedback) in accordance with multiple compression schemes, from which a transmitting device may select for a channel reporting transmission. For example, a user equipment (UE) may be configured with multiple channel state information compression schemes, corresponding to different encoders or decoders, which may involve various machine learning or neural network techniques. The UE may select or otherwise determine which compression scheme to use for channel reporting in various scenarios, including a selection based on whether a compression scheme maintains relatively accurate reporting, or whether a more power-intensive or processor-intensive compression scheme is supported by an operating mode of the UE, among other selection criteria. The UE may indicate which compression scheme was selected by a transmitted indication included with or otherwise accompanying a channel reporting transmission.
