Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives a multi-device aggregation (MDA) indication from a network entity. The MDA indication indicates an inclusion of the first UE in an aggregation of multiple UEs associated with an object. The UE then performs, based on the aggregation of the multiple UEs, an MDA operation via a physical (PHY) or medium access control (MAC) layer shared among the multiple UEs. The MDA operation includes one or more of beam management, channel state information (CSI) measurement or reporting, radio resource management (RRM), cell selection or reselection, or a positioning operation.

Abstract: Methods, systems, and devices for wireless communications are described. Repetitions of a reference signal may be transmitted by a first device. In some examples, the repetitions may be quasi-colocated with one another, share an antenna port, or both. The repetitions of the reference signal may arrive at a reconfigurable surface. The reconfigurable surface may apply a modulation sequence to the repetitions of the reference signal and output modulated repetitions of the reference signal in a direction based on a reflective state of the reconfigurable surface. A signal including the modulated repetitions of the reference signal may be received by a second device and combined with the modulation sequence used by the reconfigurable surface to obtain a combined signal. The combined signal may be used to determine, for the reconfigurable surface, information about a channel between the first device and the second device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmitted by a base station. The UE may receive system information that includes reconfigurable intelligent surface (RIS) or repeater assisted initial access information that identifies a set of SSBs that are associated with an RIS or a repeater and a modulation signature associated with the RIS or the repeater. The UE may selectively perform initial access using the SSB or search for another SSB based at least in part on the RIS or repeater assisted initial access information. Numerous other aspects are described.

Abstract: Disclosed are systems and techniques for wireless communications. For example, a process can include determining a subset of radio frequency (RF) sensing devices from a plurality of available RF sensing devices for performing an RF sensing technique for a target object. The subset of RF sensing devices may be determined based on a plurality of factors associated with the plurality of available RF sensing devices. The process can include transmitting, to at least one RF sensing device of the subset of RF sensing devices, at least one message instructing the subset of RF sensing devices to perform the RF sensing technique for the target object to obtain one or more characteristics of the target object.

Abstract: A beam pattern processing device includes: one or more memories; a transceiver; and one or more processors, communicatively coupled to the one or more memories and the transceiver. The one or more processors are configured to: configure a beam pattern information to include a sampling method of a plurality of sampling methods defining a sampling grid; send a request, including the beam pattern information, for a sampled beam pattern of the network device; and receive the sampled beam pattern obtained based on the beam pattern information.
