Abstract: Embodiments of this application provide a communication method, a communication apparatus, and a communication system. The communication method applied to a first apparatus includes: sending a first signal to a second apparatus, where a phase of the sent first signal is a first phase; receiving a second signal from the second apparatus, where the second signal and the first signal are two signals whose transmission directions are opposite on a first transmission path, a phase of the received second signal is a second phase, and the first phase and the second phase are used to adjust a data signal on the first transmission path. Based on this technical solution, the first phase and the second phase may be used to adjust the data signal, to improve reliability of data signal transmission on the first transmission path.

Abstract: A network performance improvement method and an apparatus for user equipment. In the network performance improvement method, user equipment establishes a first PDN connection and transmits data of a first application program through the first PDN connection. Then, the user equipment starts a second application program and determines whether a current network status satisfies a quality of service requirement of the second application program. When determining that the current network status does not satisfy the quality of service requirement of the second application program, the user equipment starts to establish a second PDN connection, and transmits, after the second PDN connection is successfully established, at least a part of application data of the second application program through the second PDN connection.
