Abstract: This application provides a data sending method, a data sending apparatus, and a terminal device, to improve utilization of a configured grant resource. The method includes: A terminal device receives a configuration message from a network device. The configuration message is used to indicate a configured grant, and the configuration message includes information about a timer corresponding to the configured grant. The terminal device determines that the configured grant is used for a HARQ process, and starts the timer for the HARQ process. To-be-sent data in the HARQ process is data on a first logical channel. During running of the timer, when there is to-be-newly-transmitted data on a second logical channel, the timer stops running, or a running state of the timer is ignored. The data on the second logical channel is sent by using the configured grant.

Abstract: A method for a handover of a mobile station performed by a source base station and a target base station. The target base station receives a handover request message, from the source base station, in which includes QoS information of the mobile device, radio bearer identifier information of the source base station, and a first mapping relationship between a flow and a radio bearer of the source base station, the target base station acknowledges with a handover acknowledgement message. Therefore resource preparation at the target base station during a handover procedure is improved.

Abstract: A subframe processing method and device are disclosed. The subframe processing method includes: if data packets that are not received by an evolved NodeB (eNB) include at least two consecutive Multimedia Broadcast Multicast Service (MBMS) data packets to be scheduled in a Dynamic Schedule Period (DSP) by the eNB, setting a subframe of the eNB that is used to transmit Dynamic Schedule Information (DSI) corresponding to the DSP to null. When the eNB finds that consecutive MBMS data packets are lost and/or that a type 0 Protocol Data Unit (PDU) group is lost, a subframe used to transmit the DSI may be set to null, thereby preventing the eNB from transmitting incorrect DSI which may interfere with other eNBs and cause incorrect data receiving of a user equipment (UE).
