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: The embodiments of the present invention disclose a data transmission method. A specific solution is as follows: A processor sends, by using a first resource block, a first MAC PDU that carries a first reservation indicator field used to instruct to reserve the first resource block; a receiver receives a second MAC PDU sent by using a second resource block by a set of second terminal devices, where the second MAC PDU carries a first resource feedback field used to indicate that the first resource block is successfully reserved; a processor determines, according to the first resource feedback field and that is sent by a second terminal device in the set of second terminal devices, that the first resource block is a resource block used to send a new MAC PDU; and the transmitter sends the new MAC PDU by using the first resource block.

Abstract: The present disclosure provides a backhaul link establishment method, a base station, and a device. The method includes: sending, by a base station, an offloading bearer request message to a first LPN according to a backhaul offloading establishment request message; receiving, by the base station, an offloading bearer acknowledgement message sent by the first LPN; sending, by the base station, an offloading bearer configuration message to a first UE-relay; and sending, by the base station, a received ID of a service bearer and received second S1 configuration information of the service bearer to a core network element by using an MME. In this way, backhaul load on uplink/downlink resources of the base station is reduced.

Abstract: A method includes: A first node scans another primary node based on a scanning parameter, where the first node is a primary node of at least one communication domain; and when the another primary node is not discovered through scanning, the first node listens to a first broadcast message based on random listening duration, where the first broadcast message is a broadcast message from one or more primary nodes in the another primary node, and the random listening duration is used by the first node to listen to the another primary node. The random listening duration is not fixed. Broadcast time periods of the first node and the another primary node are staggered, so that the first node can receive a broadcast message of the another primary node in the random listening duration.

Abstract: In a communication method, when MAC addresses in a plurality of VSI messages conflict, in response to only some of the VSI messages, a VSI message receiving end sends an action response message carrying a conflicting MAC address. In this way, a device that can correctly decrypt the action response message can decrypt, for a few times, ciphertext information in received action-request messages using a key of the device.

Abstract: A road side apparatus obtains a first map message. The first map message includes map element information describing a map element, and a time attribute of the map element information. The map element includes at least one of a node-level map element, a road-level map element, or a lane-level map element. The map element information includes at least one of node-level map element information, road-level map element information, or lane-level map element information. The road side apparatus sends the first map message. A terminal obtains the map element information and the time attribute from the first map message.
