System and Method for Uplink Timing in Multi-Point Communications - A simplified explanation of the abstract
This abstract first appeared for US patent application 18165032 titled 'System and Method for Uplink Timing in Multi-Point Communications
Simplified Explanation
The patent application describes a system where a user equipment (UE) receives configuration information about a carrier in a serving cell. This information includes associations between groups of uplink (UL) signals or channels on the carrier and UL timing advance groups (TAGs) of the UE. The UE then uses this information to transmit UL signals/channels based on the timing advance (TA) values of the respective UL TAGs.
- The patent application introduces a method for configuring UL signals/channels on a carrier in a serving cell for a UE.
- The UE receives two sets of configuration information, each associating a group of UL signals/channels with a specific UL TAG.
- The UE uses the TA values of the UL TAGs to determine when to transmit UL signals/channels from the corresponding groups.
Potential Applications
This technology can have various applications in the field of wireless communication systems, including:
- Mobile networks: The invention can be applied in cellular networks to improve the efficiency and reliability of UL transmissions.
- Internet of Things (IoT): The technology can be utilized in IoT devices to enhance their UL communication capabilities.
- Wireless devices: This innovation can be implemented in various wireless devices such as smartphones, tablets, and IoT sensors to optimize UL transmissions.
Problems Solved
The patent application addresses the following problems in wireless communication systems:
- Efficient UL transmission: By associating UL signals/channels with specific UL TAGs, the invention enables more efficient and organized UL transmissions.
- Timing synchronization: The technology ensures that UL signals/channels are transmitted at the correct timing based on the TA values of the UL TAGs, reducing interference and improving overall system performance.
Benefits
The technology described in the patent application offers several benefits:
- Improved UL transmission efficiency: By utilizing specific UL TAGs for different groups of UL signals/channels, the invention optimizes UL transmission resources, leading to increased efficiency.
- Reduced interference: The system ensures that UL signals/channels are transmitted at the appropriate timing, minimizing interference with other signals and improving overall network performance.
- Enhanced reliability: By organizing UL transmissions based on UL TAGs and TA values, the technology enhances the reliability of UL communications, reducing packet loss and improving the user experience.
Original Abstract Submitted
A user equipment (UE) may receive first configuration information of a carrier of a serving cell, including a first association of a first group of uplink (UL) signals or channels on the carrier in the serving cell with a first UL timing advance group (TAG) of the UE, and second configuration information of the carrier including a second association of a second group of UL signals or channels on the carrier with a second UL TAG of the UE. The UE may transmit a UL signal/channel in the first group of UL signals or channels according to a TA value of the first UL TAG, and transmit a UL signal/channel in the second group of UL signals or channels according to a TA value of the second UL TAG.
