Abstract: The aspects described herein may enable an apparatus to jointly encode two or more payloads using a single polar encoder device, while providing unequal error protection for the payloads. The apparatus causes a polar encoder to polar encode a first payload and a second payload to generate a polar encoded codeword. The polar encoder is configured to encode one or more bits of the first payload at a first reliability level and encode one or more bits of the second payload at a second reliability level, where the one or more bits of the first payload are associated with a first priority level and the one or more bits of the second payload are associated with a second priority level. The apparatus transmits the polar encoded codeword.

Abstract: A method of wireless communication by a user equipment (UE), includes estimating a downlink channel to generate a channel estimate. The method also includes obtaining multiple precoding matrices, by a channel state information (CSI) module including a neural network encoder decoder pair, based on the channel estimate and multiple different multiple input multiple output (MIMO) ranks. The method further includes determining a best rank indicator based on the precoding matrices and spectral efficiency estimates for the different MIMO ranks. The method still further includes reporting, to a base station, the best rank indicator, a channel quality index (CQI), and CSI encoder output.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine one or more parameters for a rank 5-8 Type-I codebook. The UE may perform, to a base station, a rank 5-8 channel state information (CSI) reporting based at least in part on the rank 5-8 Type-I codebook that includes the one or more parameters. Numerous other aspects are described.

Abstract: In an aspect, a UE obtains assistance data based on a set of clutter measurements associated with a plurality of network nodes, updates an RF sensing session based on the assistance data, and performs a set of measurements based on the updated RF sensing session. In another aspect, a network entity provides a first indication of a signaling scheme for a set of clutter measurements associated with a plurality of network nodes, receives, based on the signaling scheme, a second indication of the set of the clutter measurements from the plurality of network nodes, and provides, for a UE, assistance data based on the set of clutter measurements.

Abstract: A first wireless node may output a configuration of a plurality of reference signals (RSs) based on a set of sensing measurement conditions. The sensing measurement conditions may include one or more of a range resolution, a maximum range, a velocity resolution, a maximum velocity, a velocity range, an angle of arrival (AoA) measurement, an angle of departure (AoD) measurement, or a multiple-input multiple-output (MIMO) sensing occasion for radar sensing. A second wireless node may obtain the configuration of the plurality of RSs. The first wireless node may transmit the plurality of RSs for the radar sensing based on the configuration. The second wireless node may receive the plurality of RSs for the radar sensing based on the configuration. The second wireless node may perform the radar sensing based on the received plurality of RSs.

Abstract: Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a wireless device or a server. The apparatus may receive, from a network entity, an indication of clutter information from at least one sensing node or at least one sensor, where the clutter information is associated with one or more stationary or slow-moving reflections of one or more signals with respect to the at least one sensing node or the at least one sensor. The apparatus may also configure at least one filter in a set of filters at the wireless device based on the clutter information from the at least one sensing node or the at least one sensor.

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.
