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: 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.

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 TTI. The short TTIs may be allocated for V2V sidelink transmissions by non-legacy 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: 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: 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.

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.
