— 1 min read

A new joint power control method in multi-user multiplexing technique and its apparatus have been patented by ZTE Corporation, as published by the World Intellectual Property Organization. This invention is related to the communication technical field and provides a solution for optimizing the total system performance. According to the patent, the method involves determining the value of the initial power ratio of two VAMOS users, adjusting their reference power values if necessary, and optimizing the system performance based on real-time communication state.

Key Takeaways:

  • The patent provides a joint power control method for multi-user multiplexing technique, specifically for VAMOS (Voice services over Adaptive Muli-user channels on One Slot) users.
  • The method involves determining the initial power ratio of two VAMOS users (SCPIR) based on reference power values.
  • If the initial SCPIR value is out of the designated range, the reference power value of at least one VAMOS user is adjusted to ensure the adjusted SCPIR falls within the specified range.
  • The reference power value of each VAMOS user is determined using a uni-user power calculation method.
  • The technical solution optimizes the total system performance based on the real-time communication state of the users.
  • The invention is useful for improving the communication performance in multi-user multiplexing systems.

Statistics:

  • The patent was filed on 06.04.2011 under Application No. PCT/CN2011/072471.
  • The patent was published on December 29, according to Publication No. WO/2011/160481.
  • The patent relates to the communication technical field.
