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: An approach is described for a base station (gNB) that includes the following features. The features include transmitting, by the gNB, a PDCCH signal to a user equipment (UE), wherein the PDCCH signal includes an indication of a PDCCH ordered 2-step RACH procedure. The features also include receiving, by the gNB, a first step of the 2-step RACH procedure, wherein the first step includes a PRACH preamble and an associated MsgA physical uplink shared channel (PUSCH) from the UE.

Abstract: 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.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for uplink non-orthogonal multiple access transmission schemes employed by transmit circuitry. Other embodiments may be described and claimed.

Abstract: 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.

Abstract: An apparatus of an LMF node includes processing circuitry coupled to a memory. To configure the LMF node for UE location determination in a 5G NR network, the processing circuitry is to decode a measurement report message from a first Next Generation Node-B (gNBi). The measurement report message indicates a time difference (?tij) between an actual measured propagation time delay (tij) and a reference propagation time delay (Tij) between the gNBi and at least a second gNB (gNBj). The processing circuitry further performs an estimation of a UE location based on the measurement response and adjusts the estimation based on the time difference.

Abstract: Selection of time-frequency resources, for autonomous mode operation of V2V UEs, may be performed based on measurements of power transmitted by other UEs and received sidelink control information (SCI) transmitted by the other UEs. Based on these measurements, the UE may selectively exclude spectrum resources, from the set of possible resources, to obtain a final set of resources from which the UE may select resources to use for transmitting. In some implementations, the exclusion of the resources may be based on an iterative operation in which a power threshold value is incrementally modified until a candidate number of resources are available. Additionally, in some implementations, UE priority assignments may be used to obtain the power threshold value for a particular UE.

Abstract: 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.

Abstract: Various embodiments herein provide techniques for improving coverage for a physical random access channel (PRACH). Additionally, embodiments provide techniques for repetition of a channel state information (CSI) report on a physical uplink shared channel (PUSCH) for coverage enhancement. Other embodiments may be described and claimed.

Abstract: An apparatus and system to provide an enhanced repetition mechanism for PUCCH coverage enhancement are described. The resource allocation and handling mechanisms for collisions with semi-static downlink symbols and invalid symbols are described. The UE receives a PUCCH resource in RRC signalling. The PUCCH resource includes a starting symbol and number of symbols of a PUCCH repetition in a slot and a repetition factor that indicates a number of repetitions. For contiguous repetitions, a repetition that crosses a slot boundary is dropped or segmented. A segmented portion equal to 3 symbols is not transmitted.

Abstract: 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.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for uplink non-orthogonal multiple access transmission schemes employed by transmit circuitry. A transmitter circuitry in a User Equipment (UE) may include an encoder circuitry to generate an encoded sequence, a first scrambling circuitry to perform first-part scrambling on the encoded sequence to generate a first scrambled sequence, and a second scrambling circuitry to perform second-part scrambling on a spread modulated symbols to generate a second scrambled sequence. Other embodiments may be described and claimed.

Abstract: A user equipment (UE) configured for physical uplink control 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.

Abstract: Among other things, some embodiments of the present disclosure are directed to coverage enhancement techniques for PUCCH. Other embodiments may be disclosed and/or claimed.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Abstract: An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for 5G-NR sidelink communications, the processing circuitry is to select a time instance n as a resource selection trigger, and perform resource sensing during a sensing window that precedes the time instance n, to obtain a plurality of candidate resources. Resource selection is performed within a resource selection window to select at least one resource from the plurality of candidate resources for a PSSCH transmission to a second UE. The resource selection window starts after the time instance n and ends at a time instance (n+T2), where T2 is a timing value selected based on a sidelink priority value associated with the PSSCH transmission. Data is encoded for the PSSCH transmission using the at least one resource.

Abstract: Embodiments of a User Equipment (UE) and methods for device-to-device (D2D) communication are generally described herein. In some embodiments, the UE may transmit a scheduling assignment (SA) control message that indicates time transmission intervals (TTIs) to be used for a D2D transmission of a data payload by the UE to a receiving UE during an SA cycle. The UE may transmit the data payload during the TTIs indicated in the SA control message. The TTIs used for the transmission of the data payload may be included in a group of D2D TTIs reserved for D2D transmissions. In some embodiments, a time resource pattern for transmission (T-RPT) may indicate a sequence of TTI indexes for the TTIs used for the transmission of the data payload.
