Embodiment Construction

[0449] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0450] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0451] First, briefly introduce the characteristics of high-frequency communication. One of the main challenges of high-frequency communication is that the spatial transmission loss of signals is relatively large, and the communication distance is relative...

Abstract

The invention discloses an information transmission method, a device and a system. According to the embodiment of the invention, the information transmission method comprises the following steps: transmitting downstream control information to one or more second communication nodes by a first communication node in a downstream control domain of a first time unit; transmitting downstream data to one or more second communication nodes by the first communication node according to the downstream information, or / and receiving upstream data transmitted from one or more second communication nodes, wherein the first time unit comprises the downstream control domain and a data domain; and a preset resource length is set between the start position of the downstream control domain and the start position of the first time unit. By adopting the embodiment of the invention, the problems that in the prior art in high-frequency honeycomb communication, since the number of radio frequency links is limited, all downstream wave beams cannot be transmitted simultaneously on same symbols in a hybrid wave beam transmission mode, and a receiving terminal is relatively high in detection complexity, are solved.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the technical field of wireless communication, especially an information transmission method, device and system. Background technique [0002] With the development of wireless communication technology and the increasing demand of users for communication, in order to meet higher, faster and newer communication needs, the fifth generation mobile communication (5th Generation, referred to as: 5G) technology has become the core of future network development. trend. [0003] As one of the important communication means of 5G technology in the future, high-frequency communication can provide high-speed data communication by using the large bandwidth of high-frequency communication to meet the demand for large data volume in 5G communication. The industry tends to adopt hybrid beamforming, that is, radio frequency beamforming and baseband beamforming. In this method, the same Orthogonal Fre...
