    Abstract: A scrambling sequence generation method and apparatus of a device supporting Device-to-Device communication are provided. The method includes acquiring at least one of an identifier of the device, an identifier of a counterpart device and a preconfigured value; determining an initial value of the scrambling sequence for the Device-to-Device communication based on the at least one of the identifier of the device, the identifier of the counterpart device, and the preconfigured value; and generating the scrambling sequence using the initial value.

    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: A synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH) is transmitted using first and second beams. One or more symbols adjoining the first and second synchronization signals are configured to accommodate a beam switching time. At least one signal indicates a beam index for the first beam transmitting the first synchronization signal, and the beam index for the second beam transmitting the second synchronization signal is either signaled or determined based on a predetermined relationship between a resource for the first synchronization signal and a resource for the second synchronization signal. The beam indices may comprise first and second numbers of bits and/or may be jointly encoded. The beam indices may be indicated by one of the PSS, the SSS, the PBCH, a demodulation reference signal (DMRS), or a synchronization or reference signal designated for that purpose.

    Abstract: Methods and apparatuses for power control and beam management to enable coexistence of radar sensing and wireless communication. A method for a UE includes determining a sensing category or characteristics for a sensing application, and selecting a spatial filter for radar sensing transmission or reception based on determined sensing category or characteristics. The method further includes identifying a radar sensing transmission power and transmitting or receiving radar sensing signals using the spatial filter and the identified radar sensing transmission power. The method further includes reporting one of communication blockage, radar sensing beam information, or CSI adapted to the radar sensing beam information to a base station or neighboring UEs.

    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.
