Abstract: Methods and apparatus for communicating in a wireless network supporting vehicle-to-anything (V2X) communication including a terminal comprising: transceiver circuitry to communicate via uplink and downlink radio interface with a radio access network of a wireless communication network and communicate directly via sidelink radio interface with one or more out of a vehicle terminal and/or a roadside unit; and control circuitry coupled to the transceiver circuitry to determine one or more indicator related to the apparatus and/or surrounding environment and control the transceiver circuitry to control communication over the sidelink radio interface based on the determined one or more indicator to control congestion on V2X spectrum resources.

Abstract: Systems and methods of providing RAT co-existence and congestion control in V2V communications are generally described. A vUE detects specific non-LTE RAT transmissions in a listening period of a PSCCH or PSSCH, determines whether a metric has been met and reselects to a non-overloaded channel to communicate with other vUEs or the eNB. The manner of reselection is dependent on the RAT specific or V2X service priorities of the channels, as well as whether the channels are V2V service dependent.

Abstract: A wireless communication device is disclosed for setting transmission slot priorities in a broadcast environment. Upon receipt of a broadcast signal from the wireless communication environment, the UE analyzes the received signal to determine time slots in which members of its own group are transmitting. The UE then sets priorities of previously-used time slots to be low for allocation purposes. When the UE needs to transmit a signal, it first performs allocation of time slots within the signal frame. This allocation is performed based on the earlier-set priorities such that time slots identified as being used by other group members will not be used unless necessary.

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 physical channel may each be reduced by Fourier transform (FFT) size for the V2V the same factor. Doing so may enable the V2V physical channel to be implemented without significant modifications to other aspects of the LTE standard.

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: Embodiments of a User Equipment (UE) and methods for communication are generally described herein. The UE may be configured for carrier aggregation using a primary component carrier (CC) and a secondary CC. The UE may attempt to detect a sidelink synchronization signal (SLSS) from another UE on the primary CC. The UE may, if the SLSS from the other UE is detected: determine, based on the detected SLSS, a common time synchronization for the primary CC and the secondary CC for vehicle-to-vehicle (V2V) sidelink transmissions in accordance with the carrier aggregation. The UE may, if the SLSS from the other UE is not detected: transmit an SLSS to enable determination of the common time synchronization for the primary CC and the secondary CC by the other UE. The SLSS may be transmitted on the primary CC.

Abstract: Embodiments of a User Equipment (UE) and methods of communication are generally described herein. The UE may attempt to detect synchronization signals, including Long Term Evolution (LTE) synchronization signals from eNBs, New Radio (NR) synchronization signals from gNBs, and sidelink synchronization signals (SLSSs) from other UEs. The UE may prioritize an LTE synchronization signal over an SLSS, and may prioritize an NR synchronization signal over an SLSS. If the UE does not detect an LTE synchronization signal or an NR synchronization signal, the UE may select an SLSS. The UE may prioritize an SLSS from a UE that is directly synchronized to an eNB or a gNB over an SLSS from another UE that is indirectly synchronized to an eNB or a gNB.
