    Abstract: A user equipment (UE) is configured to synchronize with an independent synchronization source (I-SS) based on a first synchronization signal received from the I-SS. The UE is configured to determine whether a received signal strength from the I-SS is below a threshold value. The UE is configured to, in response to determining that the I-SS is below the threshold value, transmit a second synchronization signal propagating synchronization information derived from the I-SS to one or more peer UEs out of range of the I-SS. The second synchronization signal comprises a device-to-device synchronization signal (D2DSS).

    Abstract translation: 用户设备(UE)被配置为基于从I-SS接收的第一同步信号与独立同步源(I-SS)同步。 UE被配置为确定来自I-SS的接收信号强度是否低于阈值。 UE被配置为响应于确定I-SS低于阈值,将从I-SS导出的传播同步信息的第二同步信号发送到超出I-SS的范围的一个或多个对等UE。 第二同步信号包括设备到设备同步信号(D2DSS)。

    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 and inter-PLMN discovery announcement rate information and monitoring control configuration information.

    Abstract: A computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE). configure the UE for NR communication. The instructions cause the UE to decode sidelink control information (SCI). The SCI includes scheduling information and priority information. The scheduling information indicates time resource assignment and frequency resource assignment for sidelink data communications using a physical sidelink shared channel (PSSCH). The instructions further cause the UE to detect that a transmission (Tx) of a first set of physical sidelink feedback channels (PSFCHs) would overlap in time with a reception (Rx) of a second set of PSFCHs. The first and second sets of PSFCHs include sidelink feedback control information for the sidelink data communications. The instructions further cause transmission of at least one PSFCH from the first set of PSFCHs or the second set of PSFCHs based on the priority information.

    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.
