Abstract
The present disclosure provide a transmission method and a device, which relate to the technical field of communications and reduce overhead and improve work efficiency in an application of cooperative transmission in aspects of synchronization, sharing of information such as data and the like, obtaining of channel information and data transmission. Meanwhile application scenarios may also be extended. The method specifically includes: obtaining, by an access point AP, a parameter value, wherein the parameter value is a frequency difference between a crystal oscillator frequency of the AP and a reference crystal oscillator frequency of a reference AP or a delay difference of the AP with respect to the reference AP; compensating, by the AP, a phase difference or a time difference according to the parameter value when both of the AP and the reference AP send data. The present disclosure is applied to an application of a cooperative transmission.
