METHOD FOR PERFORMING, BY UE, CARRIER AGGREGATION VIA FIRST CARRIER WAVE AND SECOND CARRIER WAVE, IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17995350 titled 'METHOD FOR PERFORMING, BY UE, CARRIER AGGREGATION VIA FIRST CARRIER WAVE AND SECOND CARRIER WAVE, IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Simplified Explanation
The patent application describes a method for performing carrier aggregation (CA) in a wireless communication system. Carrier aggregation allows a user equipment (UE) to use multiple carrier waves simultaneously to increase data rates and improve network efficiency.
- The method involves reporting power headroom reports (PHRs) for each carrier wave. PHRs provide information about the available power resources for transmission.
- The UE receives transmission chain switching information, which determines the settings of the transmission chain for each carrier wave. The transmission chain is responsible for transmitting and receiving signals.
- The method also involves assigning transmission power for each carrier wave. The transmission power is determined based on the number of transmission chains assigned to each carrier wave and the power control value set for the carrier wave.
- If the power control value for a carrier wave exceeds the maximum output power of the assigned transmission chains, the transmission power can be adjusted based on the total number of transmission chains used for carrier aggregation.
Potential applications of this technology:
- This method can be used in wireless communication systems that support carrier aggregation, such as 4G and 5G networks.
- It can improve the overall data rates and network capacity by allowing the UE to utilize multiple carrier waves simultaneously.
Problems solved by this technology:
- Carrier aggregation can lead to increased complexity in managing transmission power and resources. This method provides a solution for efficiently assigning transmission power based on the available resources and power control values.
- It addresses the issue of exceeding the maximum output power of transmission chains by adjusting the transmission power based on the number of transmission chains used for carrier aggregation.
Benefits of this technology:
- Improved data rates and network capacity by utilizing multiple carrier waves simultaneously.
- Efficient management of transmission power and resources.
- Enhanced network performance and user experience.
Original Abstract Submitted
Disclosed is a method for performing, by a UE, carrier aggregation (CA) via a first carrier wave and a second carrier wave, on the basis of switching of a transmission chain, in a wireless communication system according to various embodiments. Disclosed are the method and apparatus therefor, the method comprising the steps of: reporting a first power headroom report (PHR) for the first carrier wave and a second PHR for the second carrier wave; receiving transmission chain switching information for changing a setting of a transmission chain for each of the first carrier wave and the second carrier wave; and assigning first transmission power for the first carrier wave and second transmission power for the second carrier wave, wherein one or more transmission chains are assigned to the second carrier wave via the transmission chain switching information, and when a power control value set for the second carrier wave is greater than first maximum output power of the one or more transmission chains, the second transmission power can be assigned on the basis of the number of all transmission chains for performing the CA and the number of the one or more transmission chains.
