Abstract: Methods and apparatuses in a wireless communication system is provided. Configuration information for defining a downlink assignment for a bandwidth part (BWP) is transmitted to a user equipment (UE) by higher layer signaling. At least one BWP is configured in a cell of the base station and the higher layer signaling is UE specific. An activated BWP is identified. Downlink control information (DCI) is transmitted on the activated BWP. Data is transmitted to the UE on the activated BWP according to the downlink assignment for the activated BWP. The downlink assignment is defined on the activated BWP, based on both the configuration information by the higher layer signaling and remaining information by the DCI.

Abstract: Methods and apparatuses for channel occupancy indication on a sidelink (SL) in a wireless communication system. A method of operating user equipment (UE) includes receiving a SL control information (SCI) format over a sidelink channel; determining, from the SCI format, at least one of: time domain information for a channel occupancy, frequency domain information for the channel occupancy, and a SL channel access procedure. The method further includes performing the SL channel access procedure before a sidelink transmission; and transmitting, upon successfully performing the sidelink channel access procedure, the SL transmission over the SL channel within the channel occupancy based on the time domain information or the frequency domain information for the channel occupancy.
