VSEngineering Contradiction Analysis

1Productivity

If heterogeneous network method is used to increase quantity of transmit antennas within unit area, then spectrum utilization is improved, but device complexity and implementation difficulty increase due to requiring new sites

Engineering Contradiction:
Improvespectrum utilizationVSAvoidimplementation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the coverage area of a macro base station into multiple sectors, and further divides each sector into multiple beam coverage areas. By transmitting wide beams and narrow beams to different beam coverage areas within the same sector, the system increases the number of transmit antennas within unit area without requiring new physical sites, thus improving spectrum utilization while avoiding the complexity of heterogeneous network deployment.

Inventive Principle:
Principle #1Segmentation

2Productivity

If heterogeneous network method is used to increase quantity of transmit antennas within unit area, then spectrum utilization is improved, but ease of operation deteriorates due to difficulty in obtaining new sites

Engineering Contradiction:
Improvespectrum utilizationVSAvoidease of implementation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent enables a single macro base station to serve multiple beam coverage areas within its sector by transmitting both wide beams and narrow beams. This multi-functional approach allows the existing base station to increase capacity and spectrum utilization without requiring additional sites, making the solution easy to implement and operate while maintaining high productivity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If wide beam and narrow beams are transmitted to same coverage area, then capacity within unit area is increased, but object-generated harmful factors increase due to potential interference

Engineering Contradiction:
Improvecapacity within unit areaVSAvoidinterference
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent applies different beam types to different spatial regions: wide beams are transmitted to wide beam coverage areas, and narrow beams are transmitted to narrow beam coverage areas within the same sector. This localized approach ensures that each beam type serves its designated area, increasing capacity while minimizing interference between beams by ensuring they operate in distinct spatial zones.

Inventive Principle:
Principle #3Local quality

AI summary

A wireless communications apparatus and method are used to resolve a problem in the prior art that increasing a system capacity by using a HetNet method causes a waste of device resources and is difficult to implement in practical application. An antenna module transmits a wide beam, transmits at least two narrow beams to a coverage area of the wide beam, and performs data transmission with UE within the coverage area of the wide beam by using at least one transmitted beam. By means of the foregoing method, under a condition that no new site is added, a quantity of transmit antennas within a unit area can be increased, and a capacity within the unit area can be increased, which is not limited in practical application and is easy to implement.
