    Abstract: Techniques for indicating a type of non-line-of-sight (NLOS) wireless signal path in a wireless communication network are described. In some embodiments, a method thereof may include receiving a plurality of reference signals, the plurality of reference signals originating from a respective plurality of wireless network nodes; determining at least one NLOS wireless signal path based on the plurality of reference signals; determining whether or not the at least one NLOS wireless signal path is introduced by a repeater of the wireless communication network based at least on a presence or an absence of a commonality among the plurality of reference signals; and indicating to a network entity whether the at least one NLOS wireless signal path is introduced by the repeater or not.

    Abstract: Disclosed are techniques for wireless sensing. In an aspect, a method for reconfigurable intelligent surface (RIS)-assisted sensing performed by a base station (BS) includes configuring one or more reciprocal RIS beam pairs for sensing, wherein each of the one or more reciprocal RIS beam pairs comprises a downlink (DL) beam having a DL angle of departure (DL AoD) from a RIS controlled by a first set of control voltages and an uplink (UL) beam having an UL AoD from the RIS controlled by a second set of control voltages. The BS may send, to the RIS, information identifying the one or more reciprocal RIS beam pairs. The BS may perform monostatic sensing using at least one of the one or more reciprocal RIS beam pairs.

    CPC classification number: H04W24/08

    Abstract: Disclosed are techniques for radio frequency (RF) sensing. In an aspect, a network entity, such as a base station, may identify an opportunity for RF sensing during which a user equipment (UE) does not transmit signals, the opportunity comprising a guard period of the UE, a bandwidth part (BWP) switching period of the UE, or a beam switching period of the UE. The network entity may transmit an RF sensing signal, receive an RF sensing signal, or both, during the opportunity for RF sensing. In an aspect, a UE may determine an opportunity for a network entity to perform RF sensing while the UE does not transmit signals, the opportunity comprising a guard period of the UE, a BWP switching period of the UE, or a beam switching period of the UE. The UE may indicate, to the network entity, the opportunity for RF sensing.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a channel state information (CSI) reference signal (CSI-RS) to a user equipment (UE) using heterogenous antenna panels, where a first antenna panel used to transmit the CSI-RS may have a different number of antenna ports than a second antenna panel used to transmit the CSI-RS. The UE may generate a codebook to report CSI based on the heterogenous antenna panels. In some cases, the UE may report compressed CSI if the antenna panels are in close proximity together.

    Abstract: A technique is performed at a user equipment (UE) for supporting one or more radio frequency (RF) sensing measurements. A reflected downlink signal is received, wherein the reflected downlink signal is transmitted as a downlink signal from a base station and reflected off of a target. An uplink signal is transmitted to be reflected off of the target and received by the base station as a reflected uplink signal. A UE receive-transmit (RX-TX) time difference is determined, representing a difference between a time at which the reflected downlink signal is received by the UE and a time at which the uplink signal is transmitted by the UE. A UE measured frequency offset is determined based on reception of the reflected downlink signal, the UE measured frequency offset comprising a Doppler shift component corresponding to a velocity of the target.
