Abstract: Embodiments of the present disclosure provide a data transmission method, user equipment, and an access network device. UE transmits air interface data to an access network device by using a serving cell set including at least two core serving cells that can independently serve the UE to transmit data, and initiates an RRC connection re-establishment process to the access network device only when detecting that all core serving cells in the serving cell set are unavailable. Data transmission is performed by using an available serving cell to the greatest extent. In other words, data transmission can be performed by using any available core serving cell, to reduce the dependence of data transmission between serving cells and minimize possibility of data transmission interruption, thereby improving data transmission robustness.

Abstract: Embodiments of the present invention provide a data transmission method, a base station, and a user equipment (UE). The method includes: generating, by a first base station, downlink radio link control (RLC) protocol data units (PDUs); and sending, by the first base station, a first part of downlink RLC PDUs in the downlink RLC PDUs to a user equipment UE, and sending a second part of downlink RLC PDUs in the downlink RLC PDUs to a second base station, so that the second base station sends the second part of downlink RLC PDUs to the UE. Hence, the first base station and the second base station are capable of jointly sending data to the UE, thereby improving a peak rate and a throughput of the UE.

Abstract: The present invention discloses a method for transmitting data on a wireless local area network (WLAN), user equipment (UE), and an access point (AP). The method includes: receiving first indication information sent by an AP, where the first indication information is used to indicate that UE can preferentially send data to the AP when the UE obtains a transmission resource through contention; determining, according to the first indication information, a first moment for sending current data to the AP, where an interval between a second moment at which the UE receives a first feedback message sent by the AP and the first moment is a first sending interval, the first feedback message is used to indicate whether a previous piece of data is successfully received, and the first sending interval is less than a distributed interframe space (DIFS); and sending the current data to the AP at the first moment.

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).
