Problems solved by technology

[0004] However, the inventors found that the above method requires significantly differentiated path losses among multi-user channels, and the path losses of multiple user channels in actual systems are difficult to meet this condition
Therefore, the scope of application of the above method is very narrow and cannot be promoted.

Embodiment Construction

[0022] The embodiment of the present invention provides a multi-user power division multiplexing method. The transmitting end allocates different transmission modes for the multi-channel signals according to the power division rule by using the status information reported by one or more users and the multi-channel signal information to be transmitted. Power, so that when there is no obvious path loss difference between multi-user channels, the multi-channel signals of these users can also be transmitted at the same time at the same frequency, which solves the problem of small signal path loss difference in power multiplexing The problem that the active power division multiplexing technology cannot work improves the network transmission capacity.

Abstract

The embodiment of the invention discloses a multi-user power division multiplexing method and device. The method comprises the steps of receiving state information reported by one or a plurality of users and multi-way signal information to be transmitted; distributing sending power to the multi-way signals of the one or the plurality of users according to the state information and the multi-way signal information; adducting the multi-way signals after power distribution to generate overlap signals of the multi-way signals. According to the method, a sending end distributes different sending powers to the multi-way signals, so that users can synchronously transmit the multi-way signals at the same frequency even if no obvious differential path loss is between the channels of the plurality of users, the problem that the existing power division multiplexing technology cannot be performed in case of small signal path loss difference in power multiplexing can be solved, and the network transmission capacity can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for multi-user power division multiplexing. Background technique [0002] In the study of the fifth-generation mobile communication standards, how to further improve the network capacity to meet the increasing demand for wireless services is one of the current research hotspots. The wireless communication networks that have been deployed and are being deployed around the world can basically be divided into two categories: time-division multiplexing systems and frequency-division multiplexing systems. Each time slot in the time division multiplexing system allows only one user to access at the same time; and each frequency band in the frequency division multiplexing system allows only one user to access at the same time. The study of information theory points out that using the broadcast characteristics of wireless channels t...
