    Abstract: Network parameter adaptation in a wireless communication system. A method for a user equipment (UE) includes receiving first information related to operation states on a cell and second information related to a search space set to receive physical downlink control channels (PDCCHs). A first operation state from the operation states includes first parameters associated with transmissions of channels or signals on the cell in one or more of a power, spatial, time, or frequency domain. A PDCCH from the PDCCHs provides a downlink control information (DCI) format that indicates one or more of the operation states. The method further includes receiving the PDCCH; determining the parameters in the one or more of the power, spatial, time, or frequency domain based on the one or more operation states indicated by the DCI format; and receiving the channels or signals on the cell based on the parameters.

    Abstract: Methods and apparatuses for supporting or utilizing a structure of a discovery signal in a wireless communication system. A method of a user equipment (UE) includes receiving a set of configurations for a discovery signal; determining a frequency location of the discovery signal; determining a time domain information of the discovery signal; determining a subcarrier spacing of the discovery signal; and determining a quasi-co-location (QCL) assumption of the discovery signal. The discovery signal includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The method further includes receiving the discovery signal from a secondary cell (SCell) based on the frequency location, the time domain information, the subcarrier spacing, and the QCL assumption of the discovery signal.

    Abstract: A method of a user equipment (UE) in a wireless communication system supporting a shared spectrum channel access is provided. The method comprises: receiving, from a base station (BS), a set of higher layer parameters including a subcarrier spacing of a physical random access channel (PRACH) preamble, a logical root index (ilog) for the PRACH preamble, and an index (zeroCorrelationZoneConfg); determining a sequence length (LRA) for the PRACH preamble based on the subcarrier spacing of the PRACH preamble; determining a physical root index (iphy) for the PRACH preamble based on the logical root index (ilog); determining a cyclic shift (NCS) for the PRACH preamble based on the index (zeroCorrelationZoneConfg); generating the PRACH preamble based on the determined sequence length LRA, the determined physical root index iphy, and the determined cyclic shift NCS; and transmitting, to the base station (BS) over the shared spectrum channel, the PRACH preamble.

    Abstract: Methods and apparatuses for contention window adjustment on a sidelink (SL) in a wireless communication system. A method of a user equipment (UE) includes determining whether hybrid automatic repeat request (HARQ) feedback is available after a last update of a contention window size (CW); determining a set of HARQ feedback corresponding to physical sidelink shared channels (PSSCHs) in a reference duration when the at least one HARQ feedback is determined as available; and determining a first condition based on the set of HARQ feedback. The method further includes determining to: reset the CW to a minimum allowed value when the first condition is satisfied or increase the CW to a next higher allowed value when the first condition is not. The method further includes performing a SL channel access procedure based on the CW and performing a SL transmission over a channel after successfully performing the SL channel access procedure.
