    Abstract: Systems and methods of providing NR V2V communications are disclosed Channel sensing is used by both UEs to determine sets of candidate resources, and subsequently select a resource, for PSCCH and PSSCH transmissions. The transmitting UE selects the PSCCH resource and transmits a scheduling request using the PSCCH resource, while the receiving UE selects a PSCCH and the PSSCH resource and transmits a scheduling grant in the PSCCH containing transmission parameters and the PSSCH resource to the transmitting UE. When the scheduling request contains the candidate resources for the PSCCH transmission, the receiving UE uses the intersection of the candidate resources for the PSCCH transmission and the candidate resources for transmission to determine the PSCCH and the PSSCH resource.

    Abstract: A user equipment (UE) can receive, from an eNodeB, a serving PLMN system information block (SIB)19 for a carrier frequency of a serving PLMN of the UE. The UE can acquire inter-frequency and inter-PLMN discovery system information acquisition assistance signaling information from the SIB19. The UE can process a non-serving PLMN SIB19 for one or more carrier frequencies of a non-serving PLMN using the inter-frequency and inter-PLMN discovery system information acquisition assistance signaling information. The UE can identify inter-frequency and inter-PLMN discovery announcement rate information and monitoring control configuration information for the one or more carrier frequencies of the non-serving PLMN to enable the UE to perform device-to-device (D2D) discovery with a UE in the non-serving PLMN according to the inter-frequency and inter-PLMN discovery announcement rate information and monitoring control configuration information.

    Abstract: A wireless communication device is configured to perform resource access in device-to-device (D2D) communication. A user equipment (UE) is provided with processing hardware comprising application processing circuitry and baseband processing circuitry. The application processing circuitry assigns a per-packet priority to data packets in the application layer. The baseband processing circuitry maps the per-packet priority to a transmission priority in the physical layer and prioritizes access to a wireless resource pool depending upon the transmission priority. A UE having the application processing circuitry and baseband processing circuitry is also provided. A computer program product is also provided. An evolved Node B (eNodeB) allocates a resource quota to a UE based upon priority information from the UE corresponding to a D2D communication to be transmitted by the UE. Other embodiments may be described and claimed.

    Abstract: Resource allocation techniques for D2D communications are described. In one embodiment, for example, user equipment may comprise one or more radio frequency (RF) transceivers, one or more RF antennas, and logic, at least a portion of which is in hardware, the logic to receive a D2D control information (D2DCI) message comprising D2D transmission pattern (DTP) information, identify a set of D2D transmission resources based on the DTP information, and send one or more D2D data messages using the set of D2D transmission resources. Other embodiments are described and claimed.
