Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) for a wireless communication system. The UE determines at least one sidelink primary synchronization signal (S-PSS) sequence of at least one S-PSS signal. The at least one S-PSS sequence is different from a primary synchronization signal (PSS) sequence. The EE also determines at least one sidelink secondary synchronization signal (S-SSS) sequence of at least one S-SSS signal. The EE determines a plurality of S-PSS symbols and a plurality of S-SSS symbols corresponding to a sub carrier spacing (SCS). The EE transmits to another EE the determined plurality of S-SSS symbols after the determined plurality of S-PSS symbols. The SCS may be associated with a physical resource block (PRB) allocation size. A maximum of 11 PRBs for a sidelink synchronization signal block (S-SSB) may be set based on the SCS.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for an access point (AP) for a wireless communication system. The AP includes processor circuitry configured to configure a bandwidth part (BWP) for downlink (DL) positioning reference signals (PRS) and a BWP for DL data transmission to a user equipment (UE), wherein the BWP for DL PRS provides DL PRS to the UE for a UE-based positioning operation. The processor circuitry is configured to select an action to be performed by the UE in response to receiving the configured BWP for DL PRS and the configured BWP for DL data transmission by the UE. The AP includes radio front end circuitry that is coupled to the processor circuitry and configured to transmit, to the UE, the configured BWP for DL PRS, the configured BWP for DL data transmission, and the selected action. The wireless communication is a 5G system or a 5G new radio (5G-NR) system.

Abstract: Some embodiments of this disclosure include apparatuses and methods for a fallback procedure for a 2-step random access channel (RACH) procedure for data transmission in a wireless communication system where the apparatuses and methods include at least generating, by a user equipment (UE), a first signal that includes a first message (MsgA) for a 2-step random access channel (RACH) procedure, transmitting, by the UE, the first signal to a next generation NodeB (gNB), determining, by the UE, whether a 4-step RACH procedure is to be used to further transmit the first signal including the MsgA, and further transmitting, by the UE, the first signal to the gNB using the 4 step RACH procedure based on determining that the 4-step RACH procedure should be used.

Abstract: A method and apparatus of a device that performs a new radio (NR) downlink (DL) positioning reference signal (PRS) resource scheduling is described. In an exemplary embodiment, the device configures at least one of a NR DL PRS Resource Pool, a NR DL PRS Resource Set, a NR DL PRS Resource, and a muting pattern. In addition, the configured NR DL PRS Resource Set may be assigned to a separate Transmission Reception Point (TRP). Furthermore, a list of configured NR DL PRS Resource Sets can be assigned to a separate TRP. The assigned NR DL PRS Resource Set may include PRS Resources with different spatial filters. In addition, the assigned NR DL PRS Resource Set can include PRS Resources with the same spatial filter.
