DEFAULT PATH LOSS REFERENCE SIGNAL IN UNIFIED TRANSMISSION CONFIGURATION INDICATION FRAMEWORK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18253448 titled 'DEFAULT PATH LOSS REFERENCE SIGNAL IN UNIFIED TRANSMISSION CONFIGURATION INDICATION FRAMEWORK
Simplified Explanation
The abstract describes a method for a user equipment (UE) in a wireless network to determine a default path loss reference signal for an uplink transmission. This is necessary when the UE is unable to determine the default path loss reference signal due to the use of a beam associated with a transmission configuration indication (TCI) state and/or the use of a repetition configuration for the uplink transmission and/or a physical downlink control channel (PDCCH) scheduling the uplink transmission.
- The UE determines the default path loss reference signal based on the repetition configuration associated with the PDCCH and/or the TCI state for an uplink control channel or uplink reference signal.
- The UE then performs an uplink power control operation for the uplink transmission using the determined default path loss reference signal.
Potential applications of this technology:
- Wireless communication networks
- Mobile devices and smartphones
- Internet of Things (IoT) devices
Problems solved by this technology:
- In a wireless network, the UE may be unable to determine a default path loss reference signal for an uplink transmission, which can lead to issues with power control and overall network performance.
- This technology solves the problem by providing a method for the UE to determine the default path loss reference signal based on the repetition configuration associated with the PDCCH and/or the TCI state for an uplink control channel or uplink reference signal.
Benefits of this technology:
- Improved power control for uplink transmissions in wireless networks.
- Enhanced network performance and reliability.
- Better communication quality for mobile devices and IoT devices.
Original Abstract Submitted
In a wireless network, a user equipment (UE) may be unable to determine a default path loss reference signal associated with an uplink transmission if the uplink transmission is transmitted using abeam associated with a transmission configuration indication (TCI) state and/or the uplink transmission and/or a physical downlink control channel (PDCCH) scheduling the uplink transmission is associated with a repetition configuration. In such cases, depending on a type associated with the uplink transmission, the UE may determine the default path loss reference signal based on the repetition configuration associated with the PDCCH and/or a TCI state for an uplink control channel or uplink reference signal. Accordingly, the UE may perform an uplink power control operation for the uplink transmission using the default path loss reference signal determined based on the repetition configuration associated with the PDCCH and/or the TCI state for the uplink control channel or uplink reference signal.
