Abstract: This application relates to the field of wireless communications, and in particular, to a resource scheduling technology for vehicle to vehicle communication in a wireless communications system. In a resource scheduling method, a first terminal device receives a second-vehicle message sent by at least one second terminal device, where the second-vehicle message carries vehicle status information of the second terminal device. The first terminal device determines a historical resource occupation status of the at least one second terminal device, and selects, based on the vehicle status information indicating a vehicle location and a traveling status of the second terminal device, a first resource used for sending a first-vehicle message.

Abstract: Embodiments of the present invention provide a data transmission method and apparatus, and relate to the communications field. The method includes: obtaining configuration information; establishing at least one logical channel according to an identifier of each logical channel and the corresponding transmission mode indication; obtaining a transmission resource according to the transmission mode indication of a logical channel to which device-to-device (D2D) buffered data belongs; and sending the D2D buffered data by using the obtained transmission resource. A problem that a resource allocation mode used by a terminal during D2D communication is relatively single and is not flexible enough is resolved, and the terminal can use different resource allocation modes according to a logical channel granularity, so that not only consumption of signaling resources of a network device can be reduced, but also QoS requirements of some services that require relatively high QoS can be satisfied.

Abstract: Embodiments of the present invention provide a cell handover method and a device. so that the target eNB uses a current serving small node as a user plane serving node after UE is handed over and uses the target eNB as a control plane serving node after the UE is handed over; receiving a handover request acknowledgment sent by the target eNB; and sending offloading configuration information of the current serving small node to the current serving small node, and sending RRC reconfiguration information of the UE to the UE, so that offloading configuration is performed separately by the current serving small node and the UE. This avoids a problem that in a cell handover process, a transmission resource required for transmission increases and a delay is relatively great because the current serving small node forwards a large amount of data to the target eNB.
Abstract translation: 本发明的实施例提供一种小区切换方法和装置。 使得目标eNB在UE切换之后使用当前服务小节点作为用户平面服务节点，并且在UE被切换之后使用目标eNB作为控制平面服务节点; 接收目标eNB发送的切换请求确认; 并向当前服务小节点发送当前服务小节点的卸载配置信息，并向UE发送该UE的RRC重配置信息，使得卸载配置由当前服务的小节点和UE单独进行。 这避免了在小区切换过程中，传输所需的传输资源增加并且延迟相对较大的问题，因为当前服务小节点向目标eNB转发大量数据。

Abstract: This application discloses a communication method, apparatus, and system. The method includes: receiving first information from a first node, where the first information is used to request to establish a first protocol data unit PDU session; sending second information to the first node, where the second information indicates an identifier of the first PDU session and a first quality of service QoS configuration policy corresponding to the first PDU session; and sending third information to the first node, where the third information indicates a data routing policy corresponding to the first PDU session, and the data routing policy includes session information of the first PDU session. In the method, a second node can configure a PDU session for the first node, so that a service provided by a core network can better meet a requirement of a terminal that does not support NAS signaling transmission.
