Problems solved by technology
Although the flexible and diverse broadcast coverage waveforms provided by the Massive system are suitable for different application scenarios, the user terminals in the network coverage area are usually unevenly distributed, and the hot spots of user terminals usually change over time. If the Massive system is deployed , if the existing broadcast coverage planning method is still used, the multi-antenna space division multiplexing capability cannot be fully utilized, and the hot spot area of the user terminal cannot be dynamically adapted, which will affect the coverage performance of the Massive system

Embodiments of the present invention provide a method and a base station for adaptive adjustment of coverage. The method includes: receiving a plurality of uplink signals sent by a plurality of user terminals within a preset period of time; according to a plurality of beam weight values stored in advance and corresponding to the first carrier, respectively mapping each uplink signal to each beam weight value corresponding to The beam area of each uplink signal is obtained in each beam area; the signal strength of the beam signal is obtained, and the total energy of the beam signal in each beam area within the preset time period is obtained according to the signal strength; The power of the adjacent cell interference noise signal in the beam area; according to the total energy of the beam signal corresponding to each beam area and the power of the adjacent cell interference noise signal, determine the target beam weight value corresponding to the first carrier, and adjust the coverage of the first carrier according to the target beam weight value scope. The base station is used to execute the above method. The method and the base station provided by the invention improve the coverage performance of the antenna system.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for adaptive adjustment of coverage and a base station. Background technique [0002] With the rapid growth of the total number of 4G users and the rapid popularization of high-definition voice and video services, the contradiction between the explosive growth of network traffic and limited spectrum resources will become more prominent in the future. Massive-MIMO technology introduces the ability of 3D beamforming in the airspace, and uses space division multiplexing technology to support time-frequency resource multiplexing of up to a dozen layers, increasing spectrum efficiency by 5-6 times, and has become an effective solution to traffic surges and The key technology of the contradiction between spectrum restriction. [0003] Under the existing technical conditions, the TDD LTE 8T8R system only supports typical broadcast coverage o...
