Abstract: Methods and apparatuses for random access procedures in a wireless communication system. A method for operating a user equipment (UE) includes receiving a system information block (SIB) in a downlink bandwidth (DL) part (BWP). The DL BWP is linked to a first uplink (UL) BWP. The SIB includes an indication for one or more UL BWPs. The method further includes transmitting a physical random access channel (PRACH) in a second UL BWP from the one or more UL BWPs. The second UL BWP is different than the first UL BWP.

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 transmit power control of sidelink (SL) channels on multiple carriers in a wireless communication system. A method of a user equipment (UE) includes receiving information related to SL operation on multiple SL carriers and simultaneous transmissions of a physical SL feedback channel (PSFCH) and a physical SL control or shared channel (PSCCH or PSSCH) and determining first and second powers for simultaneous transmissions of the PSFCH on first carriers and the PSCCH or PSSCH on second carriers. The first powers are based on values of a power control parameter associated with the first carriers. A sum of the second powers does not exceed a power difference between a maximum power and a sum of the first powers. The method further includes simultaneously transmitting the PSFCH on the first carriers using the first powers and the PSCCH or PSSCH on the second carriers using the second powers.

Abstract: Apparatuses and methods for multiple transmissions of a physical random access channel (PRACH). A method for includes identifying a set of numbers of repetitions for the PRACH preamble transmission and a first mapping among values of a PRACH mask index and a set of groups of PRACH occasions and receiving a downlink control information (DCI) format for a physical downlink control channel (PDCCH) order that indicates: a first value for a PRACH preamble index, a second value for a synchronization signal and physical broadcast channel (SS/PBCH) block index, and a third value for the PRACH mask index. The method further includes determining a number of repetitions from the set of numbers of repetitions and based on the third value and the first mapping, a group of PRACH occasions and transmitting the PRACH preamble with the number of repetitions over the group of PRACH occasions.

Abstract: Apparatuses and methods for waveform determination for uplink (UL) transmissions. A method includes receiving first information indicating whether transform precoding is enabled or disabled, second information indicating a presence of a transform precoder indication (TPI) field in a downlink control information (DCI) format, third information for a configuration related to a resource allocation associated with transmissions of physical uplink shared channels (PUSCHs) with transform precoding disabled, and a channel providing the DCI format that schedules a transmission of a PUSCH. The method further includes determining whether the transform precoding is enabled based on the TPI field, that the configuration is used when transform precoding is disabled, and that the configuration is not used when transform precoding is enabled. The method further includes transmitting the PUSCH with transform precoding and without the configuration, when transform precoding is enabled, or without transform precoding and with the configuration, when transform precoding is disabled.

Abstract: A UE includes a transceiver configured to receive first information related to a set of operation states on a cell, second information related to search space sets for receiving PDCCHs, and the PDCCHs. A first PDCCH provides a first DCI format, CRC bits of the first DCI format are scrambled by a first RNTI, and the first DCI format indicates a first index from a set of indices corresponding to the set of operation states on the cell. The UE further includes a processor operably coupled to a transceiver. The processor is configured to determine a first set of reception occasions for the PDCCHs, and absence of a correct reception of the first DCI format for the first set of reception occasions. The transceiver is further configured to transmit a PUCCH in response to the absence of the reception of the first DCI format for the set of reception occasions.
