UPLINK POWER CONTROL IN DUAL CONNECTIVITY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18052894 titled 'UPLINK POWER CONTROL IN DUAL CONNECTIVITY

Simplified Explanation

The patent application describes methods and apparatuses for managing dual connectivity in a wireless communication system. Here are the key points:

  • The method involves configuring dynamic power sharing between transmissions on a master cell group (MCG) and transmissions on a secondary cell group (SCG) in a user equipment (UE).
  • A time offset is determined based on the sub-carrier spacing (SCS) configurations and the configurations for a PUSCH (Physical Uplink Shared Channel) processing capability on the MCG and SCG.
  • The method further determines the maximum power for a PUSCH transmission on the SCG at the beginning of the transmission.
  • The transmissions on the MCG and the PUSCH transmission on the SCG are then transmitted.

Potential applications of this technology:

  • Wireless communication systems that support dual connectivity between a UE and multiple cell groups.
  • Networks that require efficient power sharing and management between the MCG and SCG transmissions.
  • Systems that need to optimize the PUSCH transmission power on the SCG.

Problems solved by this technology:

  • Efficient power sharing between the MCG and SCG transmissions, ensuring optimal utilization of resources.
  • Accurate determination of the maximum power for PUSCH transmission on the SCG, avoiding interference and maintaining quality of service.
  • Seamless coordination and scheduling of transmissions on both the MCG and SCG.

Benefits of this technology:

  • Improved overall system performance and capacity by effectively managing dual connectivity.
  • Enhanced user experience with optimized power allocation and reduced interference.
  • Efficient utilization of network resources, leading to better network efficiency and cost savings.


Original Abstract Submitted

Methods and apparatuses for managing dual connectivity. A method for operating a UE includes receiving a configuration for dynamic power sharing (DPS) between transmissions on a master cell group (MCG) and transmissions on a secondary cell group (SCG) and determining a time offset as a function of sub-carrier spacing (SCS) configurations and of configurations for a PUSCH processing capability on the MCG and on the SCG. The method further includes determining a maximum power for a PUSCH transmission on the SCG, at a beginning of the PUSCH transmission on the SCG, when each of the transmissions on the MCG is scheduled by a downlink control information (DCI) format in a PDCCH reception that ends at least the time offset before the beginning of the PUSCH transmission on the SCG. The method further includes transmitting the transmissions on the MCG and the PUSCH transmission on the SCG
