METHOD AND APPARATUS FOR CONTROLLING UPLINK TRANSMISSION POWER IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18480873 titled 'METHOD AND APPARATUS FOR CONTROLLING UPLINK TRANSMISSION POWER IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The abstract of the patent application describes a method for transmitting and receiving signals in a wireless communication system. The method involves receiving a reference signal (RS) on a first downlink bandwidth part (BWP) of a first carrier of a serving cell. Pathloss information is determined based on the received RS, and the transmission power for a physical uplink control channel (PUCCH) is determined using this pathloss information. Similarly, a second RS is received on a second downlink BWP of a second carrier of the serving cell, and pathloss information is determined for the transmission of a physical uplink shared channel (PUSCH) based on the second RS. The transmission power for the PUSCH is determined using this second pathloss information.

  • The method involves receiving reference signals on different downlink bandwidth parts of different carriers and using them to determine pathloss information for the transmission of control and shared channels.
  • The pathloss information is then used to determine the transmission power for the respective channels.
  • The method allows for efficient power control in a wireless communication system.

Potential applications of this technology:

  • Wireless communication systems: The method can be applied in various wireless communication systems, such as cellular networks, to improve the efficiency of signal transmission and power control.
  • Internet of Things (IoT): The method can be used in IoT devices and networks to optimize signal transmission and power control, leading to improved connectivity and energy efficiency.

Problems solved by this technology:

  • Inefficient power control: The method addresses the problem of inefficient power control in wireless communication systems by using reference signals and pathloss information to determine the appropriate transmission power for different channels.
  • Interference: By optimizing the transmission power based on pathloss information, the method helps reduce interference in wireless communication systems, leading to improved signal quality and reliability.

Benefits of this technology:

  • Improved power control: The method allows for more accurate and efficient power control, resulting in better overall performance of wireless communication systems.
  • Enhanced signal quality: By optimizing the transmission power based on pathloss information, the method helps improve signal quality and reduce interference, leading to better communication reliability.
  • Energy efficiency: The method helps optimize power consumption in wireless communication systems, leading to improved energy efficiency and longer battery life for devices.
