Abstract: Embodiments of the present invention provide a data sending and receiving method and device. The method includes: receiving a threshold; if a data volume of a packet to be sent is less than the threshold, sending the packet in a first data transmission manner; and if a data volume of the packet is greater than or equal to the threshold, sending the packet in a second data transmission manner. By adopting the technical solution of the present invention, a resource waste caused by transmitting small data in a data transmission manner used for transmitting a large packet in the prior art can be reduced, transmission efficiency of small data can be improved, and a transmission delay can be reduced.

Abstract: The present application provides a synchronization signal sending apparatus, sending method, receiving apparatus, and receiving method, and a system. The signal sending apparatus includes a determining unit and a sending unit. By using embodiments of the present invention, a synchronization signal is in a form of a differential signal, and has relatively strong frequency deviation resistance; and synchronization signals from different transmit ends satisfy a pre-determined relationship property. Therefore, when a receive end performs synchronization by using the synchronization signal, the receive end can eliminate an interfering signal by using the relationship property between the synchronization signals from the different transmit ends, so as to achieve an objective of distinguishing the different transmit ends or distinguishing signals from different cells.
