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.

Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for multi-transmission reception point (TRP) reception, the processing circuitry is to decode radio resource control (RRC) signaling. The RRC signaling includes configuration information configuring a plurality of transmission configuration indication (TCI) states. A media access control (MAC) control element (CE) is decoded, where the MAC CE indicates multiple active TCI states of the configured plurality of TCI states. Multiple received beams are determined using the multiple active TCI states. Downlink information is decoded, where the downlink information originates from multiple TRPs and is received via the determined multiple receive beams associated with the multiple active TCI states.

Abstract: A user equipment (UE), gNodeB or network component can be configured to support a data-aided sidelink synchronization. In response to losing a sidelink synchronization reference, sidelink synchronization tracking or performing an initial sidelink synchronization, data-aided sidelink synchronization can be performed by deriving or maintaining a sidelink synchronization from a physical sidelink control channel (PSCCH), or a physical sidelink shared channel (PSSCH) transmission of another network device, UE or vehicle to everything (V2X) based on data of another reference signal that is with the PSCCH or the PSSCH transmission.

Abstract: A method for enhanced physical downlink control channel monitoring (PDCCH) includes determining a monitoring span for monitoring a PDCCH within a slot, the monitoring span having a start symbol and a duration that spans one or more symbols within the slot. At least one of a maximum number of blind decoding (BD) attempts or a maximum number of control channel elements (CCEs) for channel estimation is determined based on the monitoring span. The PDCCH is monitored within the monitoring span up to the at least one of the maximum number of BD attempts or the maximum number of CCEs.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for causing a user equipment (UE) device to receive a configuration signaling to monitor for uplink (UL) cancellation indications; monitor a search space for an UL cancellation indication; detect an UL cancellation indication in the search space; and in response, cancel at least a portion of a scheduled UL transmission.

Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for New Radio (NR) vehicle-to-everything (V2X) sidelink communication. The processing circuitry is to determine a set of candidate resources of the UE from a sidelink resource pool, the sidelink resource divided into multiple time slots, frequency channels, and frequency sub-channels. Sidelink control information (SCI) is encoded for transmission to a second UE via a physical sidelink control channel (PSCCH). The SCI indicates a plurality of transmission resources of the set of candidate resources. A transport block is mapped across the plurality of transmission resources. A physical sidelink shared channel (PSSCH) is encoded for transmission to the second UE using the plurality of transmission resources, the PSSCH encoded to include the mapped transport block.

Abstract: In a general aspect, a User Equipment (UE) in a cellular communications network receives a Radio Resource Control (RRC) signaling message from a base station communicatively coupled to the UE over a communications channel. The UE accesses a search space in the RRC signaling message. The UE identifies a fallback Downlink Control Information (DCI) Information Element (IE) included in the search space. The UE determines whether an aggregation factor is indicated in the fallback DCI IE for shared channel communications with the base station, over multiple slots in the communications channel. The UE determines an uplink/downlink (UL/DL) configuration for transmission on the communications channel. The UE schedules an aggregated transmission over multiple slots in the communications channel based on the aggregation factor and the uplink/downlink configuration.

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 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.
