Embodiment Construction

[0068] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0069] see figure 1 , figure 1 It is a schematic diagram of a network structure applicable to an embodiment of the present invention, such as figure 1 As shown, including one or more communication nodes, such as figure 1 A first communication node 11 and a second communication node 12 are shown. The first communication node 11 may be a terminal or a base station, and the second communication node 12 may also be a terminal or a base station. For example, if the first communication node 11 is a terminal and the second communication node 12 is a base station, the communication between the terminal and the base station may be realized. Information transmission between base stations; or the first communication node 11 is a base station, and the second comm...

Abstract

The invention provides an information transmission method and a communication node. The method comprises the steps that a first communication node determines one or more transmitted beams according toa channel measurement result; the first communication node forms one or more first equivalent analog / digital transmitted beams based on the one or more transmitted beams; the first communication nodedetermines one or more second equivalent analog / digital transmitted beams according to the one or more first equivalent analog / digital transmitted beams; the first communication node forms an equivalent digital port based on each second equivalent analog / digital transmitted beam; and the first communication node transmits information through the equivalent digital port. On the basis of beam searching and tracking, information is transmitted selectively through beam broadening and digital domain frequency, so that the information is transmitted more reliably.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an information transmission method and a communication node. Background technique [0002] When channel conditions change rapidly, the acquisition of channel state information and the corresponding airspace preprocessing often cannot adapt to channel changes in a pure closed-loop transmission scheme. In this case, technologies such as transmit diversity or open-loop spatial multiplexing generally need to be considered. Existing transmit diversity schemes generally assume that the equivalent pattern of digital channels can satisfy sector coverage. The existing open-loop spatial multiplexing technology mostly adopts the combination of frequency-domain selective quasi-random precoding and CDD (Cyclic Delay Diversity, Cyclic Delay Diversity). selective. For large-scale antenna systems, similar technologies are also required to cope with complex and changeable deployment scen...
