Abstract

The present application provides a method and apparatus for obtaining beam weights, which utilizes the energy of multiple paths to generate aggregated paths, which helps to improve the quality of the generated beams, thereby improving the SNR and capacity of terminal equipment. The method includes: a network device acquires multiple paths that satisfy a multipath aggregation condition, where the multipath aggregation condition includes one or more of the following conditions: every two paths in the multiple paths need to satisfy spatially Condition, the condition that each two of the multiple paths needs to meet in terms of power; the network device determines aggregation information according to the multiple paths, and the aggregation information includes the information for the network device to generate multiple paths. The information required for the aggregated path corresponding to the path.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to a method and apparatus for obtaining beam weights. Background technique [0002] In the new radio interface (NR), a millimeter wave (millimeter wave, mmWave) frequency band of above-6 GHz is introduced, and commonly used frequency points are 28 GHz, 39 GHz, 60 GHz, and the like. When the mmWave frequency band is applied to wireless mobile communication, due to the short wavelength, the signal attenuates quickly when it propagates in space. At the same time, taking advantage of the small size of the mmWave antenna (the antenna size is proportional to the wavelength), the base station (BS) side often uses an antenna array to form beamforming (BF), so that the signal can form energy convergence in space, accurate Point to the direction of the user equipment (user equipment, UE) to improve the signal-to-noise ratio (SNR) received by the UE. [0003] In the case of n...
