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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine one or more parameters for a rank 5-8 Type-I codebook. The UE may perform, to a base station, a rank 5-8 channel state information (CSI) reporting based at least in part on the rank 5-8 Type-I codebook that includes the one or more parameters. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first downlink control information (DCI) message of a two-stage set of DCI. The UE may receive, from the base station, a second DCI message of the two-stage set of DCI. The UE may select between the first DCI message and the second DCI message as a timing reference point. In some examples, the UE may receive, from the base station, downlink data on the physical downlink channel. In some examples, the UE may transmit, to the base station, an uplink data message on the physical uplink channel.
