Abstract: A scheduling request triggering method, apparatus, and system are disclosed. The method includes: obtaining, by a terminal device, an uplink semi-persistent scheduling resource allocated by a base station, where the uplink semi-persistent scheduling resource is used to transmit to-be-transmitted data on a logical channel of the terminal device; receiving, by the terminal device, scheduling request masking set by the base station for a first logical channel; and after determining that a triggering condition is satisfied, triggering, by the terminal device, a scheduling request via the first logical channel. In this way, when a status of data of the terminal device changes, an appropriate scheduling resource can be obtained, so as to ensure timely data transmission.

Abstract: An apparatus and a method for transmitting data are included in a wireless network. The apparatus for transmitting data in a wireless network receives a status data packet sent by an upper layer, where the status data packet includes status information of the transmit end in a current status; discards, when there is a cached previous-status data packet, the previous-status data packet and caches the status data packet, where the previous-status data packet includes status information of the transmit end in a previous status; and sends the status data packet to a receive end when obtaining a sending resource, where the previous-status data packet and the status data packet have a same feature. In this way, a data packet delay is reduced; and in an application scenario of the Internet of Vehicles, timely data exchange between vehicles is ensured, and vehicle driving safety is improved.

Abstract: Embodiments of the present invention provide a method. When a target base station determines that the UE needs to be handed over from a source base station to a target base station and needs to perform a handover between a unicast bearer and a multicast/multicast bearer; because a progress of sending a data packet by using a target bearer may be slower than a progress of sending a data packet by using an original bearer, the target base station receives a data packet sent by using the original bearer and a data packet sent by using the target bearer, and when it is determined that a progress of receiving the data packet is faster than or equal to a progress of receiving the data packet by the target base station by using the target bearer, the target base station hands over the UE to the target bearer.
