Abstract: Reconfigurable intelligent surface (RIS) scheduling provided with respect to wireless communication networks is described. A base station or other network entity may serve as a central node to accommodate RIS sense and/or control requests from user equipments (UEs). A RIS scheduling protocol according to some aspects may provide a technique for avoiding potential collision at the RIS sense and/or control phases of operation with respect to RISs deployed in a wireless communication network. Using RIS scheduling, wireless communication networks may avoid or otherwise mitigate situations in which multiple sensing signals negatively impact RIS detection procedures, multiple control signals causing signal processing problems and/or control issues, and/or interference results from un-coordinated control of multiple RISs. Other aspects and features are also claimed and described.

Abstract: One or more anchor nodes, which may be sidelink devices, may transmit positioning reference signals (PRSs) to a wireless device, such as a user equipment (UE). The UE may select one or more PRSs to process based on respective priorities of the PRSs. At least one anchor node may transmit a priority indication including the respective priorities, or the one or more anchor nodes may transmit the PRSs according to a scrambling sequence or pattern to implicitly indicate the respective priorities. The UE may decode one or more PRSs based on the respective priorities.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sensing signal of a radio frequency (RF) sensing procedure at a first transmit power. The UE may receive, from a base station at least in part in response to the first sensing signal, a power control message for sensing signals of the RF sensing procedure. The power control message may indicate a power control strategy for transmitting sensing signals of the RF sensing procedure. The UE may then transmit, at a second transmit power based on the received power control message, a second sensing signal of the RF sensing procedure.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms for determining a joint priority of sidelink and access link (Uu) positioning reference signal (PRS) transmissions in a wireless communication system. A joint priority of a PRS transmission may refer to a priority of the PRS transmission over the entire set of PRS transmissions including sidelink PRS transmissions and Uu PRS transmissions transmitted to a target UE in a sidelink positioning session. In aspects, a joint priority of a sidelink PRS transmission from an anchor UE may be determined with respect to not only other sidelink transmissions, but also with respect to other Uu PRS transmissions from other anchor base stations. Similarly, a joint priority of a Uu PRS transmission from an anchor base station may be determined with respect to not only other Uu transmissions, but also with respect to other sidelink PRS transmissions from other anchor UEs.

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.
