Abstract: Apparatuses and methods for scheduling enhancements for wireless communication systems. A method for receiving physical downlink control channels (PDCCHs) includes receiving first information for first search space sets for scheduling on a first cell from the first cell and second information for second search space sets for scheduling on the first cell from a second cell. The method includes determining a first number of PDCCH receptions over a first number of non-overlapping control channel elements (CCEs) on the first cell in a first slot based on the first search space sets and identifying that at least one of the first number of PDCCH receptions exceeds a predetermined number of PDCCH receptions and the first number of non-overlapping CCEs exceeds a predetermined number of non-overlapping CCEs. The method further includes canceling PDCCH receptions corresponding only to third search space sets from the first search space sets.

Abstract: Apparatuses and methods for prioritization of uplink transmissions by repeaters. A method for a network-controlled repeater (NCR) includes receiving, by an NCR mobile termination (NCR-MT) entity, first information for a first uplink transmission by the NCR-MT entity and second information for a second uplink transmission by an NCR forward (NCR-Fwd) entity that overlap in one or more symbols. The method further includes identifying a power limit for simultaneous transmission by the NCR-MT and NCR-Fwd, determining first and second powers for the first and second uplink transmissions, respectively, and when a sum of the first and second powers in the one or more symbols exceeds the power limit, third and fourth powers for the first and second uplink transmissions, respectively, that do not exceed the power limit. The method further includes transmitting, in the one or more symbols, the first and second uplink transmissions with the third and fourth powers, respectively.

A method includes receiving first information for a set of cells, second information for a set of transmission configuration indication (TCI) states associated with each cell in the set of cells, respectively, and a first physical downlink control channel (PDCCH) that provides a first DCI format. The first DCI format schedules receptions of first physical downlink shared channels (PDSCHs) on respective first cells from the set of cells. The first DCI format includes a first TCI field indicating a combination of TCI states that includes a number of TCI states that is equal to a number of cells in the set of cells. The method further includes determining first TCI states from the combination of TCI states and receiving the first PDSCHs, or second PDSCHs after the first PDSCHs, on the first cells based on the first TCI states, respectively.

Abstract: Methods and apparatuses for physical downlink control channel (PDCCH) monitoring for multi-cell scheduling. A method for a user equipment (UE) includes receiving first information indicating a set of cells that includes more than one cell, second information indicating a first search space set that is associated with a DCI format for scheduling on multiple cells, and third information indicating an indicator value corresponding to the set of cells. The method further includes determining an association between the first search space set and the set of cells, and, based on the first search space set and the indicator value, control channel elements (CCEs) for receptions of PDCCH candidates; and receiving the PDCCH candidates over the CCEs.

Abstract: Apparatuses and methods for cross-carrier scheduling across different discontinuous reception (DRX) groups. A method includes receiving first information for a first and second sets of values for a first set of DRX timers associated with first and second DRX cell groups, respectively; receiving second information, from a first cell, for scheduling on a second cell; and receiving a physical downlink control channel (PDCCH) on the first cell. The first and second DRX cell groups do not have a common cell. The first and second cells are from the first and second DRX cell groups, respectively. The method further includes determining a first DRX Active time for the first DRX cell group based on the first set of values and the PDCCH reception and determining a second DRX Active time for the second DRX cell group based on the second set of values and the PDCCH reception.

Abstract: Methods and apparatuses for coverage enhancement of Msg3. A method for operating a user equipment includes receiving a system information block (SIB) that provides information mapping physical random access channel (PRACH) resources to enable or disable repetitions for a physical uplink shared channel (PUSCH) transmission in a random access procedure and a first time domain resource allocation (TDRA) table. An entry of the first TDRA table indicates a number of repetitions of a PUSCH transmission. The method further includes determining a PRACH resource for transmission of a PRACH, determining, based on the PRACH resource, a TDRA table from between the first TDRA table or a predetermined second TDRA table. No entry of the second TDRA table indicates a number of repetitions for a PUSCH transmission. The method further includes receiving a first grant scheduling transmission of a first PUSCH and transmitting the first PUSCH.

Abstract: Apparatuses and methods for beam management for network controlled repeaters (NCRs). A method includes identifying, by an NCR mobile termination (NCR-MT) entity, first information for a first spatial relation associated with a control link (C-link) of the NCR and second information for a second spatial relation associated with a backhaul link (BH-link) of the NCR. The method further includes receiving, by the NCR-MT entity on the NCR C-link, a downlink signal or channel using the first spatial relation and receiving, by an NCR forwarding (NCR-Fwd) entity on the NCR BH-link, a first radio frequency (RF) signal using the second spatial relation. The C-link is associated with a first cell on a first carrier frequency. The BH-link is associated with a second cell on a second carrier frequency. The first and second carrier frequencies are different. The first and second spatial relations are different.
