UPLINK DOWNLINK CONTROL INFORMATION FOR SCHEDULING MULTIPLE COMPONENT CARRIERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17906440 titled 'UPLINK DOWNLINK CONTROL INFORMATION FOR SCHEDULING MULTIPLE COMPONENT CARRIERS

Simplified Explanation

Methods, systems, and devices for wireless communications are described in this patent application. The application focuses on a user equipment (UE) receiving a downlink control information (DCI) message associated with scheduling uplink transmissions on a set of component carriers (CCs). The DCI message indicates that a first uplink channel on a first CC overlaps in time with a second uplink channel on a second CC. The UE then multiplexes uplink control information (UCI) with an uplink data transmission on either the first CC or the second CC, based on the overlap indicated in the DCI message.

• The patent application describes a method for managing uplink transmissions on multiple component carriers in wireless communications.
• The user equipment (UE) receives a downlink control information (DCI) message that indicates overlapping uplink channels on different component carriers (CCs).
• Based on the DCI message, the UE multiplexes uplink control information (UCI) with an uplink data transmission on either the first CC or the second CC.
• The UE then transmits the multiplexed UCI and uplink data on the selected CC, according to the instructions in the DCI message.

Potential Applications

This technology can find applications in various wireless communication systems, including:

• Cellular networks: It can be implemented in 4G and 5G networks to improve the efficiency of uplink transmissions.
• Internet of Things (IoT): The method can be utilized in IoT devices that require simultaneous uplink data and control information transmission.
• Wireless broadband: It can enhance the performance of wireless broadband systems by optimizing the use of available component carriers.

Problems Solved

The patent application addresses the following problems in wireless communications:

• Overlapping uplink channels: The method solves the issue of overlapping uplink channels on different component carriers, which can cause interference and degrade the quality of transmissions.
• Uplink control information (UCI) multiplexing: The technology provides a solution for multiplexing UCI with uplink data transmissions, allowing for efficient use of available resources.
• Scheduling optimization: By providing information about overlapping channels, the method enables better scheduling of uplink transmissions, leading to improved overall system performance.

Benefits

The use of this technology offers several benefits in wireless communications:

• Enhanced efficiency: By multiplexing UCI with uplink data, the method optimizes the use of available resources, improving the efficiency of uplink transmissions.
• Reduced interference: The technology helps mitigate interference caused by overlapping uplink channels, resulting in improved signal quality and reliability.
• Improved system performance: By providing better scheduling information, the method allows for optimized allocation of uplink resources, leading to overall improved system performance.

Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message associated with scheduling uplink transmissions from the UE on a set of component carriers (CCs). The DCI message may indicate that a first uplink channel on a first CC of the set of CCs at least partially overlaps in time with a second uplink channel on a second CC of the set of CCs. The UE may multiplex, based on the first uplink channel at least partially overlapping in time with the second uplink channel, uplink control information (UCI) with an uplink data transmission on the first CC or the second CC. The UE may transmit the UCI and the uplink data transmission multiplexed on the first CC or the second CC based at least in part on the DCI message.
