Abstract: Methods and apparatus for random access procedures with spatial settings. A method of operating a user equipment includes receiving a system information block (SIB). The SIB indicates a set of channel state information reference signals (CSI-RS) resources for CSI-RSs, a set of random access occasions (ROs), and a mapping between the set of ROs and the set of CSI-RS resources. The method further includes determining a first RO from the set of ROs for transmission of a first physical random access channel (PRACH), determining a first spatial setting for the first PRACH transmission based on a first CSI-RS resource from the set of CSI-RS resources that is mapped to the first RO, and transmitting the first PRACH in the first RO using the first spatial setting.

Abstract: Apparatuses and methods for flexible resource allocation for sidelink transmissions. A method of a user equipment (UE) in a wireless communication system includes receiving higher layer parameters including a bitmap; determining a first number S>1; and determining a sidelink resource pool based on the bitmap and the first number S, wherein bits in the bitmap indicate whether a group of S consecutive slots are included in the sidelink resource pool. The method further includes determining a second number L; determining L consecutive orthogonal frequency division multiplexing (OFDM) symbols within the S consecutive slots, wherein the L consecutive OFDM symbols are used for a physical sidelink shared channel (PSSCH) or a physical sidelink control channel (PSCCH); and receiving the PSSCH or the PSCCH.

Abstract: Apparatuses and methods for transmissions over multiple slots in duplex mode. A method includes receiving information for first slots that include first uplink (UL) symbols associated with first frequency resources of a sub-band (SB), second slots that include second UL symbols associated with second frequency resources of a bandwidth (BW), and transmission of a channel over a first number of slots including slots from the first slots and the second slots. The method further includes determining a first set of frequency resources within the SB for transmission of the channel over the first slots and a second set of frequency resources within the BW for transmission of the channel over the second slots. The method further includes transmitting the channel in the first set of frequency resources within the SB over the first slots and in the second set of frequency resources within the BW over the second slots.

Abstract: Apparatuses and methods for transmitting and receiving channels in duplex mode. A method includes receiving information for a location of a sub-band (SB) within a bandwidth (BW), a first set of slots, a second set of slots, and a transmission of a first channel in first frequency resources within the SB over a first set of symbols in a slot of the second set of slots. The second set of slots is included in the first set of slots and does not include slots with receptions of synchronization signals and primary broadcast channel (SS/PBCH) blocks. The method further includes transmitting the first channel within the SB over the first set of symbols in the slot. One or more symbols of the first set of symbols in the slot are downlink (DL) symbols according to the information for the first set of slots.

Abstract: Methods and apparatuses for use of flexible starting locations for SL transmissions in a wireless communication system. A method of user equipment (UE) in a wireless communication system operating with a shared spectrum channel access includes determining a set of multiple orthogonal frequency-division multiplexing (OFDM) symbols in a slot and performing a channel access procedure over a channel. The method further includes transmitting a sidelink transmission over the channel, starting from an OFDM symbol within the set of multiple OFDM symbols in the slot, upon successfully performing the channel access procedure before the OFDM symbol. The set of multiple OFDM symbols in the slot may be determined based on a higher layer configuration or pre-configurations.

Abstract: Apparatuses and methods for determination of available slots for uplink transmission. A method for operating a UE includes receiving a configuration for symbols as uplink (UL), downlink (DL), or flexible (F) and a number of repetitions for transmission of a channel. The method further includes determining an availability of a slot for transmission of a repetition of the channel and a redundancy version (RV) from a set of RVs, starting from a first RV in a set of RVs and sequentially cycling over RVs in the set of RVs. The slot is available when the repetition would not be over a DL symbol. The RV is updated when the slot is available. The RV is not updated when the slot is not available. The method further includes transmitting the repetition of the channel in the slot using the RV when the slot is available.
