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: 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.

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 a User Equipment (UE) and methods for communication are generally described herein. The UE may select, from a plurality of short transmission time intervals (TTIs), a short TTI for a vehicle-to-vehicle (V2V) sidelink transmission by the UE. The short TTIs may occur within a legacy TTL. The short TTIs may be allocated for V2V sidelink transmissions by nonlegacy UEs. The legacy TTI may be allocated for V2V sidelink transmissions by legacy UEs. The UE may transmit, in accordance with the legacy TTI, a legacy physical sidelink control channel (PSCCH) to indicate, to legacy UEs, the V2V sidelink transmission by the UE. The UE may transmit, in accordance with the selected short TTI, a short PSCCH (sPSCCH) to indicate, to non-legacy UEs, the V2V sidelink transmission by the UE.

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: User equipment (UE) positioning within a 5G New Radio (NR) network may be determined by receiving a downlink (DL) position reference signal (PRS) resource set indicating a plurality of DL PRS resources and receiving a DL PRS report configuration that indicates a set of measurements to be performed by a UE for each of the plurality of DL PRS resources within the DL PRS resource set. Position measurements may be performed for each of the plurality of DL PRS resources within the DL PRS resource set, including generating a reference signal time difference (RSTD) measurement by estimating a timing of a first arrival path from at least two of the plurality of DL PRS resources and determining a reference signal received power (RSRP) metric or a signal to noise and interference ratio (SINR) metric associated with the at least two DL PRS resources. The performed position measurements may be reported.

Abstract: 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.

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.
