COORDINATED CONTROL OF AVERAGE EIRP - A simplified explanation of the abstract
This abstract first appeared for US patent application 17995305 titled 'COORDINATED CONTROL OF AVERAGE EIRP
Simplified Explanation
The patent application describes a mechanism for controlling the average Equivalent Isotropic Radiated Power (EIRP) of multiple radio signal paths in a site. This is achieved through a coordinating controller and inner controllers for each radio signal path.
- The method involves obtaining information on long-term time averaged incoming and outgoing traffic for each radio signal path from the inner controllers.
- A time varying reference value of average transmission power per radio signal path is determined based on equalizing terms derived from the traffic information, antenna gain information, and a condition on the total average EIRP for the site.
- Individual average EIRP control is performed for each radio signal path by providing the respective time varying reference value to the corresponding inner controller.
Potential Applications
- This technology can be applied in wireless communication systems, such as cellular networks, to control the transmission power of multiple radio signal paths within a site.
- It can be used in radio frequency (RF) planning and optimization to ensure efficient and balanced power distribution across different signal paths.
Problems Solved
- The mechanism solves the problem of unbalanced power distribution among radio signal paths within a site, which can lead to coverage gaps or interference issues.
- It addresses the challenge of maintaining a desired average EIRP level for the entire site while accommodating varying traffic demands on different signal paths.
Benefits
- The mechanism allows for efficient utilization of transmission power by dynamically adjusting the average EIRP for each radio signal path based on traffic and antenna gain information.
- It ensures a balanced distribution of power, leading to improved coverage and reduced interference.
- By maintaining a desired average EIRP level, the mechanism helps optimize the overall performance and capacity of the wireless communication system.
Original Abstract Submitted
A mechanism for average Equivalent Isotropic Radiated Power (EIRP) control of at least two radio signal paths. A method is performed by a coordinating controller of a site. The site comprises the at least two radio signal paths. The method comprises obtaining, from inner controllers of the radio signal paths, information of long-term time averaged incoming and outgoing traffic per radio signal path. The method comprises determining a time varying reference value of average transmission power per radio signal path based on equalizing terms determined from the information of long-term time averaged incoming and outgoing traffic, antenna gain information per radio signal path, and a condition on total average EIRP for the site. The method comprises performing individual average EIRP control per radio signal path by providing to each respective inner controller, the time varying reference value determined for the radio signal path controlled by that inner controller.
