RADIO FRAME TRANSMISSION METHOD AND WIRELESS NETWORK DEVICE

Title:

RADIO FRAME TRANSMISSION METHOD AND WIRELESS NETWORK DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/101823

Kind Code:

A1

Abstract:

Disclosed in embodiments of the present invention are a radio frame transmission method and a wireless network device. The radio frame transmission method comprises: receiving physical random access channel (PRACH) trigger information that is borne in a first transmission subframe in a first radio frame and that is sent by a first wireless network device; and sending a preamble sequence borne in a second transmission subframe of a second radio frame to the first wireless network device in response to the PRACH trigger information, a preset first mapping relationship existing between a subframe number of the first transmission subframe and a subframe number of the second transmission subframe, and a structure of a transmission subframe in the first radio frame being different from a structure of a transmission subframe in the second radio frame. Correspondingly, also disclosed in the embodiments of the present invention is a wireless network device. By means of the present invention, transmission on PRACH through scheduling between wireless network devices can be implemented based on coordination of radio frames with different structures.
