Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message indicating a joint transmission configuration (e.g., fully coherent, partially coherent, or non-coherent) for a distributed system associated with a base station. The UE may receive reference signals from respective antenna panels of groups of distributed antenna panels. The UE may generate a channel state information (CSI) report based on the joint transmission configuration and the reference signals. In some examples, the UE may receive an indication of a reporting order for parameters in the CSI report, may separately or jointly encode channel state information reference signal resource indicators (CRIs) for the report, may modify a code-book (e.g., a precoder matrix) or cross-group co-phasing coefficients in the CSI report, or any combination thereof. The UE may transmit the CSI report to the base station.

Abstract: Certain aspects of the present disclosure provide techniques for encryption key extraction using a reconfigurable intelligent surface (RIS). A method that may be performed by a first wireless node includes receiving one or more first reference signals (RSS) as reflections off a RIS from a second wireless node. The method also includes generating a key based at least in part on a quantization of the one or more first RSs and communicating, based on the key, with the second wireless node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter of an orbital angular momentum (OAM) multiplexing based communication may determine an OAM azimuth mode assignment for open-loop transmission of a data stream using transmit diversity, wherein the OAM azimuth mode assignment comprises an assignment of two or more OAM azimuth modes to the data stream. The transmitter may transmit, to a receiver of the OAM multiplexing based communication, the data stream based at least in part on the OAM azimuth mode assignment. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for activating antenna groups at a user equipment (UE) for communications with a base station. The UE may receive an indication of at least one active antenna group for communications with the base station, and the UE may map one or more layers of an uplink message to the at least one active antenna group. The UE may then transmit the one or more layers of the uplink message using the at least one active antenna group based on the mapping. In some cases, the UE may transmit a capability report to the base station indicating one or more antennas in each antenna group in a set of antenna groups at the UE, and the base station may activate the at least one active antenna group from the set of antenna groups.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a base station may transmit subband uplink precoding information to a user equipment (UE). The base station may transmit a first control message to the UE to indicate a set of downlink resources for a downlink message associated with the subband uplink precoding information for the UE. The base station may transmit a second control message to the UE to indicate a set of uplink resources for an uplink message. The base station may transmit the downlink message to the UE via the set of downlink resources indicated by the first control message. The downlink message, the second control message, or both may include the subband uplink precoding information for the UE. The UE may transmit an uplink message to the base station via the set of uplink resources using the subband uplink precoding information.

The UE may receive, via a first RIS of the set of RISs, the signal in a first sub-band of the set of sub-bands. The UE may receive, via a second RIS of the set of RISs, the signal in a second sub-band of the set of sub-bands. The UE may transmit, based at least in part on receiving the signal, RIS information indicating at least one of: first RIS information regarding the first RIS, or second RIS information regarding the second RIS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an aerial user equipment (UE) may measure a first offset associated with a downlink frame based at least in part on a time when a downlink signal is received from a terrestrial base station. The aerial UE may determine a second offset corresponding to a starting time for the downlink frame at the terrestrial base station. The aerial UE may transmit an uplink message in an uplink frame using a timing advance that is based at least in part on a value of the first offset and a value of the second offset relative to a starting time associated with a global navigation satellite system frame duration. Numerous other aspects are described.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE sequentially maps a first number of Sounding Reference Signal (SRS) ports to a second number of orthogonal frequency-division multiplexing (OFDM) symbols. The first number and the second number are greater than one. The UE further transmits an SRS from the first number of SRS ports over the second number of OFDM symbols based on the mapping.

Abstract: Methods, systems, and devices for determining a transmit diversity across orbital angular momentum (OAM) modes are described. In some examples, a first device may select a subset of OAM modes for a transmit diversity scheme associated with communications between the first device and a second device. The first device may transmit an indication of the transmit diversity scheme, where the transmit diversity scheme may indicate the subset of OAM modes to the second device. The first device may then transmit signaling (e.g., a data packet, one or more signals, a data stream) to the second device using a set of transmitter circles of the first device. In response, the second device may transmit a feedback message, indicating signal strength measurements associated with one or more OAM modes. The first device may determine a set of OAM modes to use for subsequent signaling based on the feedback message.
