Problems solved by technology

The advantage of this method is that each node makes full use of the spectrum resources. The disadvantage is that it is difficult to determine the protection delay during multi-level relay and retransmission, which is likely to cause interruption of data packet transmission and frequent retransmission, resulting in a decrease in communication quality and a loss of wireless resources. waste
[0005] The frequency division multiplexing method is to divide the total bandwidth used for the transmission channel into several sub-frequency bands (or sub-channels), and each sub-channel transmits one signal. The advantage of this method is that each sub-channel can communicate in parallel. The disadvantage is that it requires more more spectrum resources

Abstract

The invention discloses a wireless communication system and a time domain and frequency domain resource multiplexing method thereof. The system comprises multiple stages of nodes, wherein the nodes with the father-child relationship are nodes of the same level, the root node and child nodes of the root node form a first-level node, and the child node in the previous-level node is a father node inthe next-level node; in the same-level node, the father node and the child nodes of the father node communicate in the same frequency spectrum and time division multiplexing mode; every two adjacent stages of nodes communicate in a frequency division multiplexing mode. According to the invention, the communication quality can be ensured and the waste of wireless resources can be avoided.

Description

technical field [0001] The invention relates to the field of radio technology, in particular to a wireless communication system and a method for multiplexing resources in the time domain and frequency domain. Background technique [0002] Wireless spectrum resources are a precious natural resource. With the rapid development of wireless technology, mobile high-speed data networks, wireless multimedia applications and other wireless applications with high data rate requirements have been widely deployed. The number of wireless users is exploding, and the demand for spectrum is growing accordingly. How to use limited spectrum resources to meet the spectrum requirements of various wireless applications has become a current hot research topic. [0003] In order to improve the utilization rate of wireless resources, channel multiplexing is usually used for communication. Common channel multiplexing methods include: time division multiplexing and frequency division multiplexing....
