Abstract: Methods, systems, and devices for wireless communication are described. A first wireless communication device may set parameter(s) corresponding to column(s) of a reconfigurable intelligent surface (RIS) based on a periodic coding sequence. Based on the parameter(s), the first wireless communication device may transmit a first signal to a second wireless communication device in a first direction using a first harmonic frequency, and may transmit a second signal to a third wireless communication device in a second direction using a second harmonic frequency. The second wireless communication device may decode the first signal based on the periodic coding sequence and the first harmonic frequency, and the third wireless communication device may decode the second signal based on periodic coding sequence and the second harmonic frequency. The first wireless communication device may similarly set second parameter(s) of the RIS based on a second periodic coding sequence.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reconfigurable intelligent surface (RIS) may receive configuration information indicating a passive beamforming and information transfer (PBIT) scheme, the configuration information being based at least in part on at least one of energy consumption of the PBIT scheme or an error performance of the PBIT scheme. The RIS may communicate information available to the RIS to the network device based at least in part on the PBIT scheme. Numerous other aspects are described.

Abstract: Systems and techniques are described herein for mutual authentication in wireless communication. For example, a process may include: transmitting separate authentication requests using separate MIMO channels between network nodes; transmitting an authentication proof from one network node to another; receiving configuration requests based on successful authentication of one network node by the other over the respective MIMO paths; authenticating the configuration requests; and transmitting separate configuration responses via the separate MIMO paths based on the authentication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate, within a time period, with a network node via a primary communication path comprising a link between the network node and a first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the UE. The UE may communicate, within the time period, with the network node via at least one secondary communication path comprising a link between the UE and a second electromagnetic radiation reflection relay network node. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A reconfigurable reflective surface (RIS) may receive control information from a network entity. The control information may be usable at the RIS for determination of a set of phase parameters. The RIS may determine whether distance information between the network entity and the RIS is available. The RIS may determine the set of phase parameters in accordance with the control information. The set of phase parameters may be usable by the RIS for reflecting communications from the network entity to a user equipment (UE) in accordance with a focusing distance that may be based on the determined availability of the distance information. The RIS may apply the set of phase parameters to reflect a signal from the network entity to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may identify a freshness window for a system information block and a signature that corresponds to the system information block, the freshness window having a duration that is less than a duration of a modification period for the system information block. The network node may transmit the system information block and the signature within the freshness window. Numerous other aspects are described.

Abstract: A first network node may transmit, to a second network node via a PHY SERS, and the second network node may receive, from the first network node via the PHY SERS, an indication of a first subset of a set of parameters associated with a PHY signature. The first network node may transmit, to the second network node via L3 signaling, and the second network node may receive, from the first network node via L3 signaling, an indication of a remaining subset of the set of parameters associated with the PHY signature. The first network node may transmit, to the second network node, and the second network node may receive, from the first network node, a message based on the PHY signature. The second network node may decode the message based on the PHY signature.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reconfigurable intelligent surface (RIS) device may receive a partition configuration indication that is associated with configuring a surface of the RIS device that includes multiple surface partitions, the partition configuration indication associated with activating a first subset of the multiple surface partitions, the first subset of the multiple surface partitions being based at least in part on a location of the first subset on the surface, a geometric shape formed by the first subset, and a beam. The RIS may activate the first subset of the multiple surface partitions. The RIS may deactivate a second subset of the multiple surface partitions, each surface partition in the second subset not being included in the first subset. Numerous other aspects are described.
