example 1

[0800] An embodiment of the present application provides a wireless routing method. In this method, a node is configured with a node-specific search space (that is, the air interface resource is characterized by a search space) and routing information to the destination node, and the control information carries the session Identification, according to the received control information, configured routing information, search space and other information, the node can judge whether to forward at the physical layer and if it forwards, it can know the next hop node. still with figure 2 The topology diagram shown as an example, such as Figure 21 As shown in the figure, it is a schematic diagram of the topology that identifies the configured search space for each hop provided by the embodiment of this application. In the figure, a source node is S1, and the destination node corresponding to source node S1 is D1. The information sent by S1 to D1 needs to pass through R11 , relay nod...

example 2

[0827] The embodiment of the present application also provides a wireless routing method. By configuring the node with the specific ID of the node, the routing information to the destination node, and the control information carrying the destination node or routing identification information, the node is configured according to the received control information. Information such as routing information and identification can determine whether to forward at the physical layer and know the next hop node if forwarding is required. still with figure 2 The topological diagram of the example, such as Figure 22 For this embodiment, the embodiment is in figure 2 In the figure, a source node is S1, and the destination node corresponding to source node S1 is D1. The information (data (service data or signaling)) sent by S1 to D1 needs to go through R11. Relay nodes such as R12, R13, and R14 perform forwarding and finally reach the destination node D1. The routing identification infor...

Abstract

Provided are a communication method and a corresponding device and system, the method comprising: sending first control information on a first air interface resource according to routing information, wherein the routing information comprises a feature of the first air interface resource, and the first control information is used for indicating a first resource of first information; and sending the first information on the first resource of the first information. The application can be applied to one or more of a Relay (Relay) scene, a Mesh (mesh) scene, an IAB (International Access Backhaul) scene, a V2X (Vehicle to Everything) scene, a UC (UE coordination) scene, a high-frequency transmission scene, an industrial scene, a robot coordination scene, an Internet of Things scene and the like. Through the method, the device and the system provided by the invention, the transmission delay can be reduced, and the transmission efficiency can be improved.

Description

technical field [0001] The present application relates to the field of wireless communication, and more particularly, to a communication method, device and system. Background technique [0002] The rapid development of wireless communication networks has affected all aspects of people, enabling people to quickly access communication networks at any time and anywhere. Wireless communication networks have increasingly become an indispensable part of human life. With user business needs With the increase of the increase and the diversity of demands, the pursuit of higher performance wireless communication by mobile users has never stopped. [0003] According to network scale and coverage, wireless network can be divided into Wireless Personal Area Network (WPAN), Wireless Local Area Network (WLAN), Wireless Metropolitan Area Network (WMAN), Wireless Wide Area Network ( Wireless Wide Area Network, WWAN) and so on. Due to the limited coverage of the wireless personal area netwo...
