Abstract: Example link recovery methods and apparatus are described. One example method includes determining a link failure of a first control resource set, where the first control resource set is a control resource set configured by a first master information block MIB. A link failure recovery request is sent, where the link failure recovery request is used to request to recover a communication link of the first control resource set. The first control resource set may be a control resource set (CORESET), a control region, or an enhanced physical downlink control channel (ePDCCH) set defined in a 5G mobile communications system.

Abstract: A method includes extracting packet information of a data packet to be transmitted through a Transmission Control Protocol (TCP) connection. If the packet information does not match information in a first data flow table, a first compliance detection is performed on the data packet. A state machine of the TCP connection is obtained if the first compliance detection is successful. The method also includes recording the packet information in the first data flow table, recording a connection status of the TCP connection in a first connection tracking table, and sending the data packet to a receiving end of the TCP connection. If the packet information matches the information in the first data flow table, a second compliance detection is performed on the data packet and, if the second compliance detection fails, the connection status of the TCP connection is adjusted and the data packet is discarded.

Abstract: Embodiments provide a channel sounding information feedback method, user equipment, and a base station. The method includes: determining, by UE, a first period used to periodically report channel sounding information; and periodically sending, by the UE based on received preset downlink control information DCI that is sent by a base station, the channel sounding information by using the first period as a sending period. System overheads can be reduced, a configuration response can be improved, and spectrum utilization of a system can be improved while periodic feedback of indication is reduced.
