Background

Millimeter waves (generally, the frequency range is considered to be 26.5-300 GHz), by virtue of extremely wide bandwidth and carrying capacity, have become an important deployment frequency of 5G and subsequent mobile communication technologies, but the propagation attenuation of millimeter waves in the atmosphere is very serious, and a serious challenge is posed on the effective coverage distance of communication of millimeter waves. In the current 5G standard, an optimization design is performed on the coverage problem of millimeter waves, and technical schemes such as beam forming and beam scanning are designed to improve the coverage capability of the millimeter waves, but effective coverage cannot be provided even by using the technology in non-direct-view (NLoS) scenes such as the rear of outdoor large shelters and indoor corridor corners. Electromagnetic waves such as infrared rays, visible light, ultraviolet rays and the like have higher frequency and wider bandwidth than millimeter waves, are important potential working frequency bands of the next generation of communication technology, and also face the problem of non-direct-view transmission limitation.

Because millimeter waves have better reflection characteristics, a possible solution is to add a reflection device in an NLoS scene to enhance coverage of a blind area.

Preferably, the determining whether to provide the service for the terminal according to the location information of the terminal includes:

determining power information of a reference signal of network equipment at the position of the terminal according to the position information of the terminal; the service equipment stores the electronic map information of the coverage capability of the current network, and the coverage condition of the position of the terminal can be determined according to the position information of the terminal, so that the power information of the reference signal of the network equipment of the position of the terminal is determined. Wherein the power information of the reference signal comprises: received power or received power, etc.

Correspondingly, under the condition that the service is determined to be provided for the terminal, the target reflecting device for providing the service for the terminal is determined according to the position information of the terminal, and the method comprises the following steps:

That is, when the service device determines that the coverage enhancement service needs to be provided for the terminal, the service device reads the database according to the location information of the terminal (the database of the service device maps the coverage enhancement service in the specific area with the specific reflection device in advance), so as to determine the target reflection device providing the service for the terminal according to the mapping relation.

Further, in the foregoing embodiment of the present invention, the adjustment information of the target reflection device includes: the adjustment angle of the target reflecting device;

determining a position A (x1, y1) of a target reflecting device in a preset coordinate system, a position B (x2, y2) of a network device connected with the terminal in the preset coordinate system, and a position C (x3, y3) of the terminal in the preset coordinate system; the preset coordinates are coordinate systems established by taking any point in space as a dot, as shown in fig. 3.

That is, in order to reduce the overhead of the target reflection device and the service device, the service device may set a threshold for adjusting the reflection device, and the service device may trigger the adjustment when the change threshold of the adjustment angle is greater than the second threshold. Specifically, if the service device obtains the coordinates corresponding to the position of the terminal after moving as (x4, y4), the adjustment angle of the reflection device is: [ arctan (y4-y1)/(x4-x1) + arctan (y2-y1)/(x2-x1) ]/2, the change threshold of the adjustment schedule of the target reflection device is:

For example, at a first scheduling instant, the reflection apparatus serves terminal 1 at angle N, and at a second scheduling instant, the reflection apparatus serves terminal 2 at angle M. That is, the reflection apparatuses serve a plurality of terminals without overlapping each other in the time domain, and may also be referred to as a one-time reflection apparatus that provides the best service for the terminal with the highest priority.
