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: 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.

Abstract: A user equipment (UE) can include processing circuitry configured to decode physical broadcast channel (PBCH) information received from a base station (BS). The decoded PBCH information includes a scrambled PBCH payload and an unscrambled bit sequence. A scrambling sequence is generated based on time information signaling within the unscrambled bit sequence. The scrambled PBCH payload is de-scrambled using the scrambling sequence, to obtain master information block (MIB) information. System information block (SIB) information is decoded based on the MIB information. The decoded PBCH information includes cyclic redundancy check (CRC) information. The scrambled PBCH payload and the unscrambled bit sequence can be verified based on the CRC information. The time information signaling includes one or more bits of a system frame number (SFN).

Abstract: Systems and methods are provided to determine an estimated location of a user equipment (UE). For instance, a UE can provide a positioning request to a node while the UE is in a radio resource control idle (RRC_IDLE) or inactive (RRC_INACTIVE) state. The positioning request can be implemented in a random access channel (RACH) message A (MsgA). The UE can then receive a positioning response from the node. The positioning response can be implemented in a RACH message B (MsgB).

Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth-generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a message comprising an indicator to indicate a number of contention based physical random access channel (PRACH) preambles within a PRACH occasion per Synchronization Signal Block (SSB). The second circuitry may be operable to generate a first PRACH occasion, based on the indicator.
