Embodiment 1

[0124] like figure 2 As shown, this embodiment provides a method for acquiring beam information, and the method includes:

[0125] Step S110: receiving at least one pilot beam sent by the first communication node;

[0126] Step S120: Obtain configuration information of each type of pilot beam or received configuration difference information of any two pilot beams;

[0127] Step S130: According to the configuration information or the configuration difference information, calculate the boost value of the received transmission power of any two pilot beams;

[0128] Step S140: Calculating the received channel quality information of the pilot beam;

[0129] Step S150: Selecting a pilot beam according to the boost value of the transmit power and the channel quality information;

[0130] Step S160: Determine beam information according to the pilot beam.

[0131] The first communication node is usually a fixed communication node, such as a wireless access communication device tha...

Embodiment 2

[0143] like image 3 As shown, this embodiment provides a method for sending a pilot beam, and the method includes:

[0144] Step S210: configuring more than two pilot beams;

[0145] Step S220: generating configuration information of each pilot beam or configuration difference information of any two transmitted pilot beams;

[0146] Step S230: sending the pilot beam;

[0147] Step S240: Send configuration information of each pilot beam or configuration difference information of any two pilot beams.

[0148] This embodiment is a method for sending pilot beams written from the side of the first communication node. Compared with the prior art, the pilots are divided into multiple types, and the configurations of multiple pilot beams are different, and correspond to each pilot beam. The frequency beam also sends configuration information or configuration difference information of any two pilot beams, so that the second communication node can select a beam and determine beam in...

Embodiment 3

[0163] like Figure 4 As shown, this embodiment provides a pilot beam sending method, the method comprising:

[0164] Step S310: configuring more than two pilot beams;

[0165] Step S320: Determine the time-frequency resource for sending the pilot beam according to the pre-stored mapping relationship between the time-frequency resource and various pilot beams;

[0166] Step S330: Send the pilot beam by using the time-frequency resource.

[0167]The pilot beam method described in this embodiment, compared with the existing pilot beam transmission method, firstly, more than two different pilot beams are transmitted, and each pilot beam corresponds to a fixed time-frequency Resources, so that the receiving end can obtain the configuration information of the pilot beam according to the mapping relationship between the pilot beam and the time-frequency resource, which can effectively reduce the signaling overhead. The mapping relationship is pre-negotiated between the first comm...

Description

technical field [0001] The present invention relates to beamforming technology in the field of wireless communication, in particular to a beam information acquisition method, a pilot beam transmission method, a communication node and a system. Background technique [0002] Beamforming is a technology for directional data transmission. Through beamforming directional data transmission, energy is concentrated in a useful direction, which increases the signal-to-noise ratio of the system, thereby improving the coverage of the system. [0003] The pilot information refers to a kind of information that is known by both the first communication node and the second communication node and sent by the first communication node on the designated time-frequency resource. The second communication node estimates the channel information between the first communication node and the second communication node according to the received pilot information, calculates the channel quality informati...
