Abstract: Directional sensing capability, including number of beams, beam-width, analog or digital beam sweeping, and supported waveforms, may be indicated by a user equipment (UE), which may then receive a configuration for directional sensing including number of beams, maximum or minimum beam-width, reception time between transmission beam sweeping, and waveform. The UE then performs directional sensing based on the received configuration. The configuration for directional sensing may be for one of monostatic sensing with reception periods between consecutive sensing signal transmissions or bistatic sensing using a plurality of beams. The UE's directional sensing capability may include capability of spatial multiplexing of sensing signals with communication signals. The configuration for directional sensing may permit spatial multiplexing of sensing signals with communication signals. The UE may determine to perform spatial multiplexing of sensing signals with communication signals based on orthogonality of a desired sensing beam with a beam for communications.

Abstract: A time domain resource configuration indicates a time domain resource for sensing operations by a user equipment, and a frequency domain resource configuration indicates a bandwidth part (BWP) for the sensing operations. The user equipment performs the sensing operations using the indicated time domain resource and the indicated bandwidth part. The time domain resource configuration may include a sensing type indicator S for the time domain resource for sensing operations, and may indicate that dynamic triggering of sensing is allowed. The BWP for the sensing operations may comprise BWP(s) selectively activated for the sensing operations, and may indicate BWP(s) that overlap a BWP used for cellular communication. Assistance information for interference between sensing operations and cellular communication may be transmitted by the user equipment, which may subsequently receive a configuration for coexistence of the sensing operations and the cellular communication.

Abstract: Methods and devices for transmission symbol modulation that accounts for distortion introduced by a power amplifier (PA). A user equipment (UE) comprises a transceiver and a processor. The transceiver is configured to transmit, to a base station (BS), UE capability information that indicates support for adjusted symbol constellations, wherein the adjusted symbol constellations are adjusted to pre-compensate for distortion effects of a power amplifier (PA) in the transceiver, and receive, from the BS, a modulation and coding scheme (MCS) indication. The processor is configured to determine, based on the MCS indication, an adjusted symbol constellation, and generate modulation symbols from input bits according to the determined adjusted symbol constellation. The transceiver is further configured to transmit, to the BS, the modulation symbols.

Abstract: Methods and apparatuses for support of machine learning (ML) or artificial intelligence (AI) assisted channel state information (CSI) feedback. A method performed by a user equipment (UE) includes transmitting capability information indicating a capability of the UE to support a ML based parameter configuration associated with CSI reports; receiving configuration information that indicates parameters for the ML based parameter configuration associated with the CSI reports; and receiving CSI reference signals (RSs). The method further includes measuring the CSI-RSs; determining, based on the configuration information, the measured CSI-RSs, and information related to localized observations of channel statistics in one or more domains, configuration parameters in the one or more domains for the CSI reports; determining, based on the configuration parameters in the one or more domains, a CSI report; and transmitting the CSI report.

Abstract: UE capability for support of machine-learning (ML) based channel environment classification may be reported by a user equipment to a base station, where the channel environment classification classifies a channel environment of a channel between the UE and a base station based on one or more of UE speed or Doppler spread, UE trajectory, frequency selectivity or delay spread, coherence bandwidth, coherence time, radio resource management (RRM) metrics, block error rate, throughput, or UE acceleration. The user equipment may receive configuration for ML based channel environment classification, including at least enabling/disabling of ML based channel environment classification. When ML based channel environment classification is enabled, UE assistance information for ML based channel environment classification, and/or an indication of the channel environment (which may be a pre-defined channel environment associated with a lookup table), may be transmitted by the user equipment to the base station.
