APPARATUS AND METHODS FOR BETTER ESTIMATION OF RADIATION POWER UTILIZING PAPC COMPENSATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17453160 titled 'APPARATUS AND METHODS FOR BETTER ESTIMATION OF RADIATION POWER UTILIZING PAPC COMPENSATION

Simplified Explanation

The abstract describes a base station that includes multiple antennas and a data unit (DU) and a massive MIMO unit (MMU). The DU receives a signal to be transmitted and obtains per-antenna-power-constraint (PAPC) information. It then determines an estimated effective transmission power (P) based on the PAPC information and pre-schedules the signal for transmission based on this power. The MMU receives the pre-scheduled signal from the DU, performs pre-coding to normalize the per-antenna gain of the antennas, and provides the pre-coded signal for transmission via the antennas.

  • The base station has multiple antennas and includes a data unit (DU) and a massive MIMO unit (MMU).
  • The DU receives a signal to be transmitted and obtains per-antenna-power-constraint (PAPC) information.
  • The DU determines an estimated effective transmission power (P) based on the PAPC information.
  • The DU pre-schedules the signal for transmission based on the estimated effective transmission power (P).
  • The MMU receives the pre-scheduled signal from the DU.
  • The MMU performs pre-coding on the pre-scheduled signal to normalize the per-antenna gain of the antennas.
  • The MMU provides the pre-coded signal for transmission via the antennas.

Potential Applications

  • This technology can be applied in wireless communication systems, such as cellular networks, to improve the efficiency and performance of base stations.
  • It can be used in 5G and future generations of wireless networks to enhance the capacity and coverage of the network.

Problems Solved

  • The technology addresses the issue of power constraints in base stations with multiple antennas.
  • It solves the problem of optimizing the transmission power and scheduling of signals to maximize the performance of the base station.

Benefits

  • The use of multiple antennas and pre-coding techniques improves the signal quality and reduces interference in wireless communication.
  • The technology enables efficient utilization of available power resources in base stations.
  • It enhances the overall capacity and coverage of wireless networks, leading to improved user experience and network performance.


Original Abstract Submitted

A base station includes a plurality of antennas, a data unit (DU) comprising a first processor and a first memory containing instructions, which when executed by the first processor, cause the DU to receive a signal to be transmitted via the plurality of antennas, obtain per-antenna-power-constraint (PAPC) information, determine an estimated effective transmission power (P) based on the PAPC information, and pre-schedule the signal for transmission based on the P. The base station further includes a massive MIMO unit (MMU) comprising a second processor and a second memory containing instructions, which when executed by the second processor, cause the MMU to receive, from the DU, the pre-scheduled signal, perform pre-coding on the pre-scheduled signal based on a current value of a PAPC determined at the MMU to normalize per-antenna gain of antennas of the plurality of antennas, and provide the pre-coded signal for transmission via the plurality of antennas.
