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).

Systems and methods of providing new radio positioning

A user equipment (UE) implementing power control for a 2-step random access channel (RACH) procedure is provided. The UE determines a first transmission power of a physical random access channel (PRACH) preamble to be used during a 2-step RACH procedure. The UE determines a second transmission power of a physical uplink shared channel (PUSCH) transmission to be used during the 2-step RACH procedure based on the first transmission power of the PRACH preamble. The UE then performs the 2-step RACH procedure based on the first transmission power of the PRACH preamble and the second transmission power of the PUSCH transmission. The UE switches to a 4-step RACH procedure from the 2-step RACH procedure based on a determination that the PRACH preamble was successfully detected and the PUSCH transmission was falsely detected, and performs the 4-step RACH procedure based on the first transmission power of the PRACH preamble.

Method and UE for power control for two-step random access procedure

A method and device are disclosed for performing collision resolution in a two-step random access channel (RACH) process. In such a process, an MsgA PUSCH signal and a grant based PUSCH signal may collide. When such a collision is detected, either the MsgA PUSCH signal or the grant based PUSCh signal are dropped. The other of the two signals is then transmitted. The determination regarding which signal to drop can be based on a set of rules stored in memory.

On collision handling of MsgA PUSCH in 2-step RACH and other uplink channels

Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.

Hybrid automatic repeat request (HARQ) based on codeblock groups in new radio systems

Devices and methods provide for transmitting downlink (DL) positioning reference signals (PRSs) in a wireless system. A DL PRS resource pool is configured and divided into a plurality of DL PRS resource sets. The DL PRS resource pool includes a periodically repeated amount of resources dedicated for DL PRS transmission by a plurality of gNBs in the wireless communication system. The plurality of DL PRS resource sets correspond to one or more gNB of the plurality of the gNBs. The DL PRSs are encoded for transmission on configured DL PRS resources within the plurality of DL PRS resource sets.

Radio (NR) downlink (DL) positioning reference signal (PRS) design resource allocation and mapping in NR positioning

Embodiments disclosed herein are directed to new mechanisms of resource allocation for transmission of positioning or ranging (e.g., sounding) reference signals. The embodiments may provide flexible and/or efficient resource allocation, and may improve accuracy of user positioning. The techniques described herein may be applied for multiple use cases, including UAS, V2X, IIoT, etc.

Distributed resource management mode for NR positioning

A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.

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.

Systems, methods, and circuitries are disclosed for determining a position of a wireless device. In one example, an apparatus for a first wireless communication device including baseband circuitry having a radio frequency (RF) interface configured to transmit and receive RF signals is provided. The apparatus includes one or more processors configured to process a signal received from a second wireless communication device to identify at least first arrival path and a different arrival path between the first wireless communication device and the second wireless communication device; and determine a location of the second wireless communication device based on the first arrival path and the different arrival path.

Techniques for improving new radio (NR) positioning performance

Methods disclosed herein may include receiving, at a gNB from a UE, a minimum time gap between a reception at the UE of a configuring message that configures a sending of an SL transmission by the UE and the sending of the SL transmission. Alternatively, the minimum time gap may be measured from the reception at the UE of a DCI message that triggers an SL transmission and the sending of the SL transmission. The method may further include determining, at the gNB, timing information (e.g., an offset, or an absolute time) for the UE to use to schedule the SL transmission, the timing information based on the minimum time gap; generating, at the gNB, a message including a field indicating the timing information; and sending, from the gNB, the message to the UE. Analogous methods for UEs are also disclosed herein. Systems implementing these methods are also disclosed.

Systems and methods of providing timing of SL transmission when scheduled by NR gNB

Implementations of this disclosure generally may relate to the field of wireless communications. More specifically, implementations described in this disclosure relate to different 3GPP LTE and LTE-A system enhancements to address the issue and support reliable V2X operation in the high mobility environments. Several solutions to improve the V2X system performance in the high mobility vehicular channel propagation conditions are described. Some aspects relate to the suggestion of a new DMRS patterns within individual subframes that promote more accurate CFO estimation. Moreover, another aspect provides DMRS mapping or puncturing patterns to transmit individual DMRS in a periodic pattern on respective OFDM/SC-FDMA symbols so that they do not occupy all REs of the OFDM/SC-FDMA symbols, respectively.

A user equipment (UE), gNodeB or network component can be configured to support Quality of Service (QoS) aware sidelink communications for vehicle to everything (V2X) communication operations. The QoS aware sidelink communications can include operating QoS congestion control, QoS control and adaptation, QoS aware resource allocation, QoS aware in-device coexistence operations, as well as sensing and reservation based on sidelink resource allocations. Transmitter constraints can be provided according to a Quality of Service (QoS) aware congestion control that enables a fair usage of spectrum resources with one or more V2X devices, based on QoS attributes. Different V2X packets can be scheduled/filtered based on combinations of the QoS attributes. A priority of one radio access technology (RAT) over another can be made based on the QoS attributes associated with the different V2X packets being delivered in sidelink transmissions for a QoS aware in-device coexistence operation.

QoS-aware congestion control, resource allocation and in-device coexistence solutions for NR V2X sidelink communications

A non-transitory computer-readable storage medium stores instructions for execution by one or more processors of a UE. The instructions configure the UE for low latency NR positioning in a 5G NR network and cause the UE to perform operations comprising decoding configuration signaling received from a base station. The configuration signaling includes measurement gap information and scheduling information for a UE measurement report. A downlink (DL) positioning reference signal (PRS) received from the base station is decoded. Positioning measurements are performed using the DL PRS. The positioning measurements are performed based on a measurement gap corresponding to the measurement gap information. The UE measurement report is encoded for a UL transmission to the base station based on the scheduling information. The UE measurement report includes the positioning measurements.

Techniques for supporting low latency NR positioning protocols

A user equipment (UE) configured for physical uplink shared channel (PUSCH) repetition in an fifth-generation (5G) new radio (NR) network decodes a downlink control information (DCI) format that includes a scheduling grant for a PUSCH transmission. For a codebook-based PUSCH transmission, the DCI format indicates at least a first and a second transmit precoder matrix indicator (TPMI) index for PUSCH repetition. The UE may apply a precoder matrix determined from the first TPMI index to encode a PUSCH for a first PUSCH transmission occasion of the PUSCH repetition and may apply a precoder matrix determined from the second TPMI index to encode the PUSCH for a second PUSCH transmission occasion. For a non-codebook-based PUSCH transmission, the DCI format indicates at least a first and a second sounding reference signal (SRS) resource indicator (SRI) for PUSCH repetition. The UE may apply the first SRI to encode the PUSCH for the first PUSCH transmission occasion and may apply the second SRI to encode the PUSCH for the second PUSCH transmission occasion.
