Abstract

The invention provides a data transmission method and device, and the method includes the steps that network equipment determines that there is a to-be-transmitted first wakening frame in a first timeperiod, wherein the first wakening frame is used for wakening first terminal equipment, the first time period comprises a preset first transmitting moment of a beacon frame which is transmitted periodically, and the length of the first time period is greater than zero or equal to zero, and is less than the transmitting period of the beacon frame, and the first time period is a first transmittingmoment when the length of the first time period is zero; and the network equipment transmits the first wakening frame, so as to replace the transmission of the beacon frame. The method and device provided by the invention can reduce the cost of the beacon frame.

Description

technical field [0001] The present application relates to the communication field, and more particularly, to a data transmission method and device in the communication field. Background technique [0002] With the diversification of mobile applications and the continuous development of mobile terminals, a large number of battery-powered mobile terminals have emerged. Reducing the energy consumption of mobile terminals has become one of the important technologies for future wireless networks. Wake-up radio (wake-upradio, WUR) technology is a technology to reduce the power consumption and cost of the terminal. In the WUR system, the mobile terminal can intelligently select the appropriate time to enter the power saving mode, that is, turn off the main radio of the mobile terminal, so that The terminal works in narrowband mode, and can continuously monitor the narrowband signal when the main radio is turned off. Once a wake-up packet (WUP) is received from the network device, t...
