Abstract: Techniques are provided for implementing time reversed reference signals for radio frequency (RF) sensing operations in a communication system. An example method for generating channel reciprocity information for radio frequency sensing operations includes receiving radio frequency sensing information from a sensing node, generating a channel reciprocity prediction based at least in part on the radio frequency sensing information and a channel reciprocity prediction model, and providing an indication for time reversal precoding to the sensing node based on the channel reciprocity prediction.

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.

Abstract: Radio frequency (RF) sensing by a sensing entity with an oscillator that introduces frequency errors is supported using dual direction bistatic sensing. The sensing entity transmits a sensing signal that is reflected by an object and received by a second sensing entity, which measures a first frequency offset that includes an oscillator error from the transmission of the sensing signal and a Doppler shift from the object. The sensing entity also receives and measures a second frequency offset of a sensing signal transmitted by the second sensing entity and reflected by the object, which includes a second frequency offset that includes an oscillator error from the reception of the sensing signal and a Doppler shift from the target object. The velocity of the object may be estimated based on a combination of the first and second frequency offsets, which cancels the oscillator error caused by the sensing entity.

Abstract: A UE receives DCI scheduling a PUSCH spanning multiple sub-bands, the DCI indicating a first precoder for a first resource grid of the PUSCH and a second precoder for a second resource grid of the PUSCH. The UE transmits the PUSCH with the first precoder at the first resource grid and with a third precoder at the second resource grid, the third precoder being based on a phase rotation of the second precoder. A base station transmits DCI scheduling a PUSCH spanning multiple sub-bands, the DCI indicating a first precoder for a first resource grid of the PUSCH and a second precoder for a second resource grid of the PUSCH. The base station receives the PUSCH with the first precoder at the first resource grid and with a third precoder at the second resource grid, the third precoder being based on a phase rotation of the second precoder.
