Abstract

The invention provides a signal sending method and device, and the method comprises the steps that a terminal obtains first configuration information containing first OFDM cyclic suffix length information at a first moment, then obtains the first OFDM cyclic suffix length from the first configuration information, and communicates with network equipment at a second moment by using the first OFDM cyclic suffix length. An OFDM cyclic suffix is added in uplink and downlink communication, so subcarrier orthogonality damage caused by inter-symbol interference between an interference signal and a desired signal is avoided, and the system throughput is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a signal sending method and device. Background technique [0002] From the first-generation analog cellular mobile communication network in the mid-1970s to the mid-1980s with the Global System for Mobile Communications (English: global system for mobile communications, referred to as: GSM) and IS-95 (English: Interim Standards 95) as the representative of the second-generation mobile communication system, and then to the third-generation mobile communication system proposed by the International Telecommunication Union (English: International Telecommunication Union, referred to as: ITU) in 1985, until the fourth and fifth-generation mobile communication systems that are widely used For mobile communication systems, the duplex method is usually Frequency Division Duplex (English: Frequency Division Duplex, referred to as: FDD), Time Division Duplex (English...
