Abstract: A first access network device determines a timing offset of a first carrier and a second carrier. The timing offset is an offset between timing of downlink communication of the first carrier and timing of uplink communication of the second carrier. The first carrier is a carrier using a first radio access technology (RAT), and the second carrier is an uplink frequency division duplex (FDD) carrier using the first RAT and a second RAT. The first access network device sends first indication information to a terminal. The first indication information indicates the timing offset, and the timing offset is used to determine the timing of the second carrier. Based on this scheme, the terminal can use a shared frequency band resource of LTE, thereby improving resource utilization.

Abstract: This application discloses a pulse shaping method, a transmitter, a receiver, and a system. The transmitter includes an inverse Fourier transform module, a pulse shaping filter, a pulse shaping controller, and a parallel-to-serial conversion module. The pulse shaping controller is configured to: receive pulse configuration signaling, generate, based on the pulse configuration signaling, a pulse parameter corresponding to a to-be-configured pulse, and output the pulse parameter to the pulse shaping filter. The pulse shaping filter is configured to: perform subcarrier-level filtering on an output signal of the inverse Fourier transform module, perform pulse shaping processing on the output signal of the inverse Fourier transform module based on the pulse parameter, and output a processed signal in serial by using the P/S module. Different pulse parameters correspondingly represent different pulse shapes. In the foregoing solution, pulse shaping can be flexibly configured, to support different communication scenarios.

Abstract: Embodiments of the present invention provide a method, an apparatus for sending and receiving a reference signal, and a terminal device. The method includes: when a bandwidth satisfies a given condition, sending or receiving a reference signal symbol only once in every N subframes; and when the given condition is not satisfied, increasing the sending or receiving of the reference signal. The method also includes adjusting a granularity of sending or receiving the reference signal with the change of the bandwidth, and the signaling and processes required during the adjustment process. By means of the method and apparatus, the reference signal overhead can be effectively reduced, while good communication quality is ensured, thereby achieving good compromise between communication effectiveness and reliability.
