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: Methods and apparatuses for beam indication for full duplex. A method of operating a user equipment (UE) includes receiving first and second information that includes first and second transmission configuration indicator (TCI) state configurations associated with first and second subsets of slots or symbols, respectively, on a cell and receiving a downlink control information (DCI) format that includes a first or second TCI state code point from the first or second TCI state configuration. The method further includes determining, based on whether a slot or symbol is from the first or second subset, the first or second TCI state code point and receiving, based on the determination, a shared data or control channel or signal using the first or second TCI state code point. The first subset does not include time-domain resources indicated for simultaneous transmission and reception on the cell and the second subset does.

Abstract: Methods and apparatuses for adaptive cross-carrier scheduling and flexible physical uplink control channel (PUCCH) groups. A method for receiving physical downlink control channels (PDCCHs) or transmitting PUCCHs includes receiving first information for a first group of cells and for a second group of cells and receiving second information for activation of only one of the first group of cells and the second group of cells. The method also includes determining a group of cells to be activated based on the second information and receiving the PDCCHs only on first cells from the activated group of cells or transmitting PUCCHs only on second cells from the activated group of cells.

Abstract: Methods and apparatuses for switching of physical downlink control channel (PDCCH) monitoring capabilities in a wireless communication system. A method for operating a user equipment includes receiving information to skip reception of a number of PDCCHs over a number of slots; determining an instruction to receive first PDCCHs in first slots from the number of slots based on a transmission of a physical uplink control channel (PUCCH) that provides a positive scheduling request (SR) in a first slot that is before the first slots, or skip the reception of the number of PDCCHs in the number of slots based on an absence of transmission of the PUCCH in the first slot; and based on the instruction, receiving the first PDCCHs in the first slots or skipping the reception of the first PDCCHs in the number of slots.

Abstract: A method of a user equipment (UE) in a wireless communication system is provided. The method includes identifying a condition for providing an energy status report (ESR) and determining one or more values of an available energy level corresponding to one or more time instances. A first value of the available energy level, from the one or more values, at a first time instance, from the one or more time instances, is determined based on a first value of a maximum transmit energy level at the first time instance. The first value of the maximum transmit energy level is determined based on the first time instance. The method further includes determining a first ESR comprising the one or more values of the available energy level and the corresponding one or more time instances, determining uplink resources for transmission of a first uplink channel with the first ESR, and transmitting the first uplink channel with the first ESR in the uplink resources.

Abstract: Methods and apparatuses for multiple concurrent random access procedures. A method for operating a user equipment includes receiving first configuration for a random access (RA) procedure, initiating a first RA procedure on a cell based on the first configuration, and initiating a second RA procedure on the cell prior to completion of the first RA procedure. A method for a base station includes transmitting a first random access response (RAR) and a second RAR. The first RAR includes a first temporary cell radio network temporary identifier (TC-RNTI) and a first uplink grant. The second RAR includes a second TC-RNTI and a second uplink grant. The method further includes receiving a first PUSCH scheduled by the first uplink grant and a second PUSCH scheduled by the second uplink grant. The first PUSCH includes the first TC-RNTI. The second PUSCH includes only the first TC-RNTI or both the first and second TC-RNTIs.

Abstract: Methods and apparatuses in a wireless communication system is provided. A method for operating a user equipment (UE) includes receiving a set of higher layer parameters and downlink control information (DCI); determining, based on the set of higher layer parameters, whether a field is present; and determining, from the DCI, a first set of antenna ports for de-modulation reference signal (DM-RS) associated with a first physical downlink shared channel (PDSCH). The method further includes, in response to a determination that the field is present, determine that a second set of antenna ports for DM-RS are not associated with a second PDSCH for another UE and receiving the first PDSCH over a downlink channel. The second set of antenna ports for DM-RS: are orthogonal to, have a same resource element mapping as; and have a different frequency domain orthogonal cover code (FD-OCC) from the first set of antenna ports for DM-RS.
