Abstract

The invention discloses a point-to-point physical layer communication method and device in an ad hoc network, sending UE and receiving UE, and the method comprises the steps: sending a synchronizationsignal frame carrying beacon indication information, the synchronization signal frame being used for achieving the time and frequency domain synchronization of two communication parties; sending a beacon frame according to the beacon indication information, wherein the beacon frame is used for indicating sending information of a data frame; sending the data frame according to the sending information; wherein the synchronization signal frame, the beacon frame and the data frame are included in the same superframe of ad hoc network communication. Through the method, the transmission efficiencyof effective data can be improved, and adaptive adjustment can be flexibly carried out according to the communication condition of the ad hoc network.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a point-to-point physical layer communication method and device in an ad hoc network, a sending UE and a receiving UE. Background technique [0002] Compared with common wireless networks that combine base stations and terminals, ad hoc networks do not have a central scheduling unit for wireless resources. Therefore, each node in an ad hoc network plays both the role of a base station and a terminal, and generally uses fixed frequency resources and error correction Coding and modulation methods realize the sharing of wireless resources between different nodes through time division. [0003] For this networking method, the point-to-point communication of the self-organizing network generally adopts the superframe structure and frame structure of the Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 protocol, such as figure 1 as shown, figur...
