Abstract: Devices and systems of sensing, resource selection and control signaling for feedback-less and feedback-based NR-V2X sidelink communication are described. Resource reservation and selection for sidelink retransmissions based on HARQ feedback are described for unicast, groupcast, and broadcast blind retransmissions. After exchanging HARQ feedback capability information for different types of communications, a HARQ-dependent or HARQ-independent resource selection occurs. Look-ahead and/or chain-based resource selection and reservation signaling is used, in which a single resource or some or all of the resources selected are signaled as reserved. Further resource selection of a single additional resource may occur after an initial resource selection. The resource selection for retransmissions may be adapted using a RSRP or distance threshold.

Abstract: 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.

Abstract: An apparatus of user equipment (UE) comprises processing circuitry and memory. The processing circuitry decodes radio resource control (RRC) signaling received from an enhanced node B (eNB), wherein the RRC signaling includes an information element (IE) including information of a multi-cast broadcast single frequency network (MBSFN) subframe pattern of neighboring cells of a serving cell of the eNB. The processing circuitry initiates detection of CRS information of neighboring cells by the UE, the CRS information including one or both of physical cell identifiers (Cell IDs) and a number of CRS antenna ports (APs) of the neighboring cells; and initiates neighboring cell CRS interference mitigation (CRS-IM) using the detected CRS information and the received information of the MBSFN subframe pattern. The memory stores the information of the MBSFN subframe pattern.

Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for active bandwidth part (BWP) switching, the processing circuitry is to decode RRC signaling configuring a plurality of BWPs for the UE. The RRC signaling further includes an indicator for an initial BWP of the plurality of BWPs for initial use by the UE as an active BWP. DCI received on a PDCCH is decoded, which includes a BWP indicator for switching the active BWP from the initial BWP to another BWP of the plurality of BWPs. RF and baseband parameters to switch the active BWP from the initial BWP to the another BWP are reconfigured. Reconfiguring the RF and baseband parameters cause an interruption of one or more slots of a serving cell of the UE. A starting time of the interruption is within a time duration of a BWP switching delay supported by the UE.

Abstract: Systems and methods provide solutions for delay and interruption requirements for vehicle-to-everything (V2X) sidelink carrier aggregation (CA). For example, when any number of component carriers is added for V2X CA, a user equipment (UE) capable of V2X sidelink communication is allowed an interruption of up to two subframes to the cellular network. The interruption may be for both uplink and downlink of a serving cell or primary cell.

Abstract: A vehicle may wirelessly communicate with another vehicle via a physical channel (a vehicle-to-vehicle (V2V) channel) that is robust and reliable under high mobility propagation conditions. The physical channel may be created by modifying an existing long-term evolution (LTE) physical channel, such as an LTE sidelink (SL) channel. For instance, the V2V physical channel may be created by increasing, by a particular factor, the subcarrier spacing of legacy LTE channels (e.g., from 15 kilohertz (kHz) to 30 kHz). Additionally, a symbol duration and a fast Fourier transform (FFT) size for the V2V physical channel may each be reduced by the same factor. Doing so may enable the V2V physical channel to be implemented without significant modifications to other aspects of the LTE standard.
