Abstract: Methods and apparatuses for a sidelink synchronization signals and physical sidelink broadcast channel block (S-SS/PSBCH) block structure for unlicensed operation. A method of a user equipment (UE) in a wireless communication system includes determining a subcarrier spacing (SCS) of a sidelink synchronization signals and physical sidelink broadcast channel (S-SS/PSBCH) block; determining a set of interlaced resource blocks (RBs). The set of interlaced RBs includes RBs with a uniform interval k. The method further includes mapping the S-SS/PSBCH block to the set of interlaced RBs and transmitting, to another UE, the S-SS/PSBCH block over a sidelink channel.

Abstract: Methods and apparatuses for physical downlink control channel (PDCCH) enhancements in a wireless communication system. A method of operating a user equipment (UE) includes receiving a synchronization signals and physical broadcast channel (SS/PBCH) block and determining a set of configurations for a control resource set (CORESET #0) for a Type0-PDCCH. The set of configurations include a subcarrier spacing (SCS) for the CORESET #0 that is same as the SS/PBCH block; a multiplexing pattern between the CORESET #0 and the SS/PBCH block; a time domain offset (O) to determine slots including monitor occasions for the Type0-PDCCH; and an index of a starting symbol within at least one of the slots. For a first multiplexing pattern between the CORESET #0 and the SS/PBCH block, the time domain offset (O) is configurable based on the SCS of the CORSET #0. The method further includes receiving the Type0-PDCCH based on the set of configurations for CORESET #0.

Abstract: A method for a user equipment (UE) is provided. The method includes receiving first information related to reception of reference signals (RSs). The RSs include channel state information RSs (CSI-RS) or synchronization signals. The RSs are associated with a beam failure (BF) detection, a radio link failure (RLF) detection, or a CSI report. The method further includes receiving second information related to hypothetical adaptation of transmission powers of the RSs and the RSs based on the first information. The method further includes determining, based on the second information and the reception of the RSs, reporting quantities indicating hypothetical channel conditions and transmitting a channel with the reporting quantities indicating the hypothetical channel conditions.

Abstract: Methods and apparatuses for cell discontinuous transmission (DTX) and discontinuous reception (DRX). A method performed by a user equipment (UE) includes receiving information related to set(s) of parameters associated with cell DTX or cell DRX on a cell and an indication for activation or deactivation of the cell DTX or the cell DRX. The set(s) of parameters include a cycle, a start offset, or an on-duration timer. The cell DTX and the cell DRX share common parameters. The method further comprises determining an active period and a non-active period of the cell DTX or the cell DRX based on the indication for activation or deactivation, determining a start of the cell DTX or DRX on-duration timer based on a system frame number (SFN), and receiving or transmitting channels or signals on the cell based on the determined active and non-active periods of the cell DTX or the cell DRX, respectively.
