Abstract: A user equipment (UE) transmits a first transmission comprising first sidelink control information (SCI) using a first cyclic shift, where the first SCI includes information about a second cyclic shift of second SCI for a second transmission from the UE. The UE then transmits the second transmission comprising the second SCI using the second cyclic shift. A receiving UE receives, from a second UE, a first transmission comprising first SCI having a first cyclic shift and uses information in the first SCI to determine cyclic shift information about a second cyclic shift of second SCI for a second transmission from the UE. The receiving UE may exclude the second cyclic shift from selection using the information received in the first SCI.

Abstract: Techniques disclosed provide for enhanced V2X communications by defining information Elements (IE) for V2X messaging between V2X entities. For a transmitting vehicle that sends a V2X message to a receiving vehicle, these IEs are indicative of a detected vehicle model type detected by the transmitting vehicle of a detected vehicle; a pitch rate of the transmitting vehicle, a detected vehicle, or a detected object; a roll rate of the transmitting vehicle, a detected vehicle, or a detected object; a yaw rate of a detected vehicle, or a detected object; a pitch rate confidence; a roll rate confidence; an indication of whether a rear brake light of a detected vehicle is on; or an indication of whether a turning signal of a detected vehicle is on; or any combination thereof. With this information, the receiving vehicle is able to make more intelligent maneuvers than otherwise available through traditional V2X messaging.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be an eNB. The eNB informs UE(s) of a change in at least one of a first configuration for transmission of ACKs/NACKs by the UE(s) for DL transmissions received by the UE(s) or a second configuration for reception of ACKs/NACKs by the UE(s) for UL transmissions sent by the UE(s). The eNB indicates to the UE(s) one or more resources in which the UE(s) is to transmit the ACKs/NACKs for the received DL transmissions or is to receive the ACKs/NACKs for sent UL transmissions. The eNB indicates to the UE(s) a subset of the DL transmissions to the UE(s) for which the UE(s) is to transmit the ACKs/NACKs or a subset of the UL transmissions by the UE(s) for which the UE(s) is to receive the ACKs/NACKs.

Abstract: Methods, apparatus, and computer-readable mediums for wireless communication are provided. One apparatus is configured to receive at least one SA from at least one UE. The apparatus is further configured to determine an energy associated with each at least one SA. The apparatus is also configured to rank data transmission time-frequency resources based on the determined energy associated with said each received at least one SA. Each at least one SA are associated with a different subset of the data transmission time-frequency resources. The apparatus is further configured to select a set of data transmission time-frequency resources based on the ranked data transmission time-frequency resources and to send a data transmission on the selected set of data transmission time-frequency resources. Another apparatus is configured to partitioning time-frequency resources into different resource groups, to divide UEs into UE groups based on location, and map the UE groups to the resource groups.

Abstract: An improved manner of transmitting and receiving messages in V2X/V2V/D2D is presented in which a transmitting device determines a geographic location of the mobile transmitting device and generates a message for a service group having a group ID associated with the service group, the message comprising a first indication of a geographic area associated with the message, the geographic area based at least in part on the geographic location of the transmitting device. Then, the apparatus transmits the message to the service group, e.g., via V2X/V2V/D2D communication. A receiving device then determines its geographic location and determines whether to send a feedback for the message based on the first indication of the geographic area associated with the message and the geographic location of the receiving device.

Abstract: Aspects directed towards a network-assisted sidelink scheduling operation are disclosed. In one example, a scheduled entity receives a grant of resources from a scheduling entity operating according to a legacy radio access technology (RAT), and translates the grant of resources from a legacy configuration of resources to a non-legacy configuration of resources. The scheduled entity then performs a sidelink communication via the non-legacy configuration of resources. In another example, a scheduling entity operating according to a legacy RAT transmits a system information block (SIB) to a scheduled entity indicating that the scheduling entity can allocate non-legacy resources. The scheduling entity then receives a request for resources from the scheduled entity that corresponds to a non-legacy sidelink communication, and provides a grant of resources to the scheduled entity that includes a non-legacy-specific frequency for transmitting the non-legacy sidelink communication.
