Abstract: In some implementations, a base station may send, to a user equipment (UE), a message indicating that an RF sensing signal is to be used for the RF sensing, wherein the message indicates: the RF sensing signal comprises a modified synchronization signal block (SSB) for supporting both sensing and initial access/mobility, or the RF sensing signal comprises a non-SSB sensing reference signal (S-RS) of a secondary cell (Scell) and has a quasi co-location (QCL) relationship with a root SSB of a primary cell (Pcell). The base station also may transmit the RF sensing signal.

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: Methods, systems, and devices for wireless communication at a communication device are described. The communication device may be configured to support reporting of power imbalances between antennas of the communication device. In some cases, the communication device may report a power imbalance between at least two of the antennas in the form of a power offset value based on a respective antenna polarization. In other cases, the communication device may report the power imbalance between the at least two antennas in the form of a power offset value based on a respective antenna panel. In some other cases, the communication device may be configured to report the power imbalance between the at least two antennas in the form of a power offset value for each separate antenna. The communication device may transmit a report with an indication of the power imbalance (e.g., power offset value) to the network.

Abstract: Aspects relate to configuring active groups of antenna ports. An apparatus may support different groups of antenna ports. One or more of these groups may be designated as active (e.g., for a scheduled transmission). In some examples, a first apparatus may send to a second apparatus an indication of the active groups. The second apparatus may then use the active groups for a transmission.

Abstract: Aspects of the disclosure involve multiplexing the transmission of communications signals and sensing signals at the resource element level. A frequency modulated continuous wave (FMCW) signal and plurality of orthogonal frequency-division multiplexing (OFDM) signals may be transmitted within an air interface frame structure having a plurality of resource elements, each resource element defined over a symbol duration in a time domain and a subcarrier in a frequency domain. The FMCW signal occupies a first plurality of resource elements and comprises a FMCW waveform repeated in the time domain and transmitted during a first symbol, over a first plurality of subcarriers of the air interface frame structure. The plurality of OFDM signals occupy a second plurality of resource elements in the air interface frame structure and are transmitted during the first symbol, over a second plurality of subcarriers of the air interface frame structure.
