Abstract
A data transmission method and a device are provided. The method includes: a first device receives a first signal sent by a second device; and the first device determines whether to send data according to the first signal. According to the data transmission method and device, the first device sends data according to the first signal received from the second device, for example, sends data when the signal is stronger than a certain threshold value.
Claims17
A method for data transmission, comprising:
- receiving, by a first device, a first signal sent by a second device;
- and
- determining, by the first device, whether to send data according to the first signal;
- wherein receiving, by the first device, the first signal sent by the second device comprises:
- determining, by the first device, position information, or signal strength information, or position information and signal strength information, wherein the position information is used for indicating a position of the first device, and the signal strength information is used for indicating strength of a second signal received by the first device;
- and receiving, by the first device, the first signal sent by the second device according to the position information, or the signal strength information, or the position information and the signal strength information;
- wherein receiving, by the first device, the first signal sent by the second device according to the position information comprises:
- determining, by the first device, a distance between the first device and the second device according to the position information;
- receiving, by the first device, the first signal sent by the second device when determining that the distance between the first device and the second device is less than or equal to a first threshold;
- or
- wherein receiving, by the first device, the first signal sent by the second device according to the signal strength information comprises:
- receiving, by the first device, the first signal sent by the second device when determining that the strength of the second signal is larger than or equal to a second threshold.
