Abstract: Apparatuses and methods for dormancy indication via multi-cell scheduling. A method includes receiving first information for a set of serving cells and a downlink control information (DCI) format. The DCI format schedules reception of a physical downlink shared channel (PDSCH) on a first serving cell from the set of serving cells, includes a frequency domain resource allocation (FDRA) field providing a first value that is associated with the first serving cell and is different from predetermined values, and provides an indication for a dormant or a non-dormant active downlink (DL) bandwidth part (BWP) for each serving cell from second serving cells. The method further includes receiving the PDSCH on the first serving cell and determining the dormant or non-dormant active DL BWP for each serving cell from the second serving cells based on the indication.

A method includes receiving first information for a set of cells that includes a first cell and a second cell, second information for a table providing time domain resource allocation (TDRA) indexes mapped to respective downlink (DL) BWPs of respective cells from the set of cells, and receiving a DCI format that schedules a first physical downlink shared channel (PDSCH) on a first DL BWP of the first cell and a second PDSCH on a second DL BWP of the second cell. The method further includes determining a first time-domain resource indicated by a first TDRA index that is mapped to the first DL BWP, and a second time-domain resource indicated by a second TDRA index that is mapped to the second DL BWP, and receiving the first and second PDSCHs in the first and second time-domain resources, respectively.

Abstract: Methods and apparatuses for power information for uplink configurations. A method includes receiving information indicating that a first downlink control information (DCI) format scheduling transmission of a physical uplink shared channel (PUSCH) includes a transform precoding indication (TPI) field and a channel providing a DCI format scheduling transmission of a first PUSCH. The method further includes determining whether the DCI format is the first or a second DCI format and a power headroom report (PHR). When the second DCI format, the PHR includes a single PHR associated with a transform precoding used for the transmission of the first PUSCH. When the first DCI format, the PHR includes first and second PHRs associated with first and second transform precodings, respectively, for the transmission of the first PUSCH. The method further includes transmitting the first PUSCH with the PHR using either the first or second transform precoding.

A method for operating a user equipment includes determining a first physical random access channel (PRACH) preamble for transmission in a first PRACH occasion (RO) using a first spatial setting and determining a second PRACH preamble for transmission in a second RO using a second spatial setting. The method further includes transmitting the first PRACH preamble in the first RO using the first spatial setting and transmitting the second PRACH preamble in the second RO using the second spatial setting. The method further includes receiving a first physical downlink control channel (PDCCH) scheduling a reception of a first physical downlink shared channel (PDSCH) using a third spatial setting associated with the first spatial setting, or a second PDCCH scheduling a reception of a second PDSCH using a fourth spatial setting associated with the second spatial setting.

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.

Abstract: A method includes receiving information for a set of radio link monitoring (RLM) reference signals (RSs) corresponding to a first subset of slots on a cell and a first set of parameters associated with an evaluation of the set of RLM RSs and receiving the set of RLM RSs. The method further includes determining a first reception quality for a RLM RS from the first set of RLM RSs; determining, based on the first reception quality and an adjustment value, a second reception quality for a second subset of slots from the set of slots; and determining a radio link failure for the second subset of slots when the second reception quality is below a reception quality threshold for a time period. The second subset of slots includes time-domain resources indicated for simultaneous transmission and reception on the cell and slots from the first subset of slots does not.
