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 communications are described. For instance, a base station may transmit, to a user equipment (UE), control signaling indicating a configuration for transmitting a reference signal for reconfigurable surface configuration. The base station may receive, via a reconfigurable surface, the reference signal based on transmitting the control signaling. For instance, the reconfigurable surface may reflect the reference signal to the base station using a first configuration of the reconfigurable surface. The base station may transmit, to a controller of the reconfigurable surface, a set of parameters for configuring the reconfigurable surface to a second configuration for communications between the base station and the UE based on receiving the reference signal via the reconfigurable surface.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device (e.g., a base station) may transmit, to a user equipment (UE), an indication of a field type of a field between the UE and the wireless device. The indication of the field type may include one or more bits indicating the field type, a measure indicating a likelihood that the field type includes a first field type as compared to a second field type, an indication that the first type is the same as a second field type configured at the UE, or any combination thereof. The UE may select between a first set of beam weight vectors and a second set of beam weight vectors based on the field type. The UE may communicate, with the base station, a reference signal using a beam generated using a first beam weight vector from the selected set.

Abstract: Methods, systems, and devices for connection setup in an orbital angular momentum (OAM)-based communication system are described. A first device and a second device may establish an OAM communications connection between the devices. The first device and the second device may exchange a series of messages over a downlink communications link and an uplink communications link according to an OAM mode. Based on OAM related parameters or OAM related information included in the messages, the first device and the second device may achieve a successful directional alignment (co-axial alignment) between the first device and the second device. The first device and the second device may determine one or more orbital angular momentum modes for communication between the first device and the second device based on the establishing the directional alignment.
