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).

Abstract: Embodiments disclose a data processing method, and a communications device and system. The method includes: transmitting, by a communications device, a data packet to a receiving node by using an unlicensed spectrum resource and by using a hybrid automatic repeat request process. The method also includes determining, by the communications device, that the unlicensed spectrum resource is unavailable and an unsuccessfully-sent data packet exists in the hybrid automatic repeat request process. The method also includes triggering, by the communications device, ARQ retransmission for the unsuccessfully-sent data packet.

Abstract: Embodiments of the present application provide a certificate management method and apparatus in an NFV architecture. The certificate management method includes: determining, by an MANO, a storage network element, where the storage network element is configured to store a certificate of a VNFC, and the storage network element is different from the VNFC; creating, by the MANO, storage space in the storage network element, where the storage space is used to store the certificate of the VNFC; and sending, by the MANO, an address of the storage space to the VNFC, so that the VNFC accesses the address of the storage space, obtains the certificate of the VNFC, and directly communicates with another network element by using the certificate stored in the storage network element. The VNFC does not locally store the certificate.

Abstract: The present invention provides a method and an apparatus for sending uplink/downlink scheduling information, and a method and an apparatus for receiving uplink/downlink scheduling information. The method for sending downlink scheduling information includes: determining, in downlink subframes on a second carrier, a first downlink subframe, in which at time corresponding to the first downlink subframe, a subframe on a first carrier is an uplink subframe; and sending, on a fifth downlink subframe on the first carrier, downlink scheduling information corresponding to the first downlink subframe on the second carrier to a terminal, in which time corresponding to the fifth downlink subframe is before the time corresponding to the first downlink subframe. The present invention achieves the purpose of performing uplink and downlink scheduling on a second carrier through a first carrier bearing a PDCCH.
