Problems solved by technology

[0006] However, if the relative position between the base station and the UE antenna module changes at different times due to factors such as high-speed movement of the UE, the beam pair determined by the above-mentioned beam correspondence method may not be able to achieve the best transmission effect, thereby affecting the transmission performance.

Embodiment approach

[0305] In the first implementation manner, the UE dynamically determines the beam to be scanned according to the displacement deviation value determined in real time.

[0306] In an embodiment of the present disclosure, the preset scanning range configuration information includes: a correspondence between a preset displacement deviation value and the first preset scanning range information;

[0307] Wherein, the preset displacement deviation value corresponds to the above-mentioned displacement reference value, for example, it may be a speed deviation value, a rotation angle and other values. The above-mentioned first preset scanning range information may be preset beam deviation amount, or preset coverage angle information.

[0308] see Figure 6 According to a flowchart of another beam correspondence method shown in an exemplary embodiment, the step 122-2 may include:

[0309] In step 1221, determine the difference between the displacement reference value and the preset sc...

Abstract

The invention provides a beam correspondence method and device, user equipment and a base station. The method comprises the steps that scanning configuration information for the corresponding state ofa beam is determined, and the scanning configuration information is used for indicating that when the relative position between an antenna module of user equipment and a base station changes in the corresponding state of the beam, beam scanning is carried out to re-determine an optimal matched beam pair; in the beam corresponding state, beam scanning is triggered according to the scanning configuration information, a beam corresponding result is obtained, and the beam scanning is used for re-determining the optimal matching beam pair; and sending the corresponding result of the beam to the base station, so that the base station determines a transmission beam by referring to the corresponding result of the beam. By adopting the wave beam corresponding method provided by the invention, thetransmission performance of information transmission of the system by adopting the high-frequency wave beam can be ensured.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a beam correspondence method and device, user equipment, and a base station. Background technique [0002] 5G NR (New Radio) has opened up many new frequencies for transmission. The use of high-frequency spectrum is a feature of 5G NR, among which the application of millimeter wave (mmwave) with a frequency above 6GHz is the most typical. [0003] In the millimeter wave application of the 5G NR system, beamforming technology is used to transmit information between the base station and the user equipment (UE). The communication process is roughly as follows: the transmitting end such as the base station uses a large-scale antenna array to transmit In the direction, the high-frequency beam with a frequency above 6GHz is sent; the receiving end uses the millimeter-wave antenna module to receive the above-mentioned beam, and establishes a communication connecti...
