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.

Abstract: A signal transmission method includes: A first node sends a first preamble on a first channel; and the first node transmits a signal frame on the first channel, where the first preamble indicates a type of the signal frame. Because the first preamble transmitted by the first node on the first channel may indicate a type of a signal frame subsequently transmitted by the first node, different types of signal frames are indicated by the first preamble in different scenarios, so that signal transmission requirements in different scenarios can be met. For example, in a ranging scenario, the first preamble may indicate that the signal frame is a ranging frame. An apparatus is configured to perform the transmission method.

Abstract: An apparatus 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 apparatus 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.
