Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a capability report indicating one or more capability parameters that are associated with wideband interference measurement of an orthogonal frequency division multiplexing (OFDM) channel and a supported subband size for the OFDM channel. The UE may receive, from the network node, configuration information indicating an interference measurement resource associated with a set of frequency domain resources, wherein the set of frequency domain resources includes a greater number of frequency domain resources than the supported subband size. The UE may measure, based on the reception of the configuration information, the interference measurement resource to obtain interference measurement information associated with the OFDM channel. The UE may transmit, to the network node, a measurement report indicating the interference measurement information. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) may send, to a first entity, first information indicating a maximum number of positioning signal transmissions or a maximum power for positioning signal transmissions that the UE can support. The UE may receive, from the first entity, configuration information for changing a positioning mode of the UE to a positioning mode selected from a first positioning mode and a second positioning mode. The UE may perform a positioning operation according to the selected positioning mode. In some aspects, the first positioning mode is a normal positioning mode in which the UE sends UL positioning reference signals to a plurality of TRPS, and the second positioning mode is a UL power-limited mode in which the UE sends UL positioning reference signals to only one or a small number of TRPs.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process may include receiving, at a network device (e.g., a user equipment (UE)) from a network entity via a number of sensing streams based on a maximum of Nt−J sensing streams, a waveform including communications resources and sensing resources. The waveform has a rank Nt and J is a number of layers scheduled for multiple-input multiple-output (MIMO) communications that is less than Nt. The process may further include processing at least the communications resources of the waveform.

Abstract: Disclosed are techniques for communication. In an aspect, a network entity determines a location of a reference location device (RLD) based on positioning measurements of one or more positioning reference signal (PRS) resources, and determines whether a potential man-in-the-middle attack has occurred based on whether a location error of the RLD is negative and a comparison of an absolute value of the location error and a threshold.
