Wireless device for transmitting time-sensitive data efficiently
The patent US12075462B2 describes a wireless device designed to efficiently manage and transmit time-sensitive data alongside other data categories. The device features a time-sensitive queue for prioritizing time-sensitive data and a first category queue linked to a specific access category. A first controller is responsible for obtaining transmission opportunities based on predefined contention parameters. When a transmission opportunity arises, the device can generate a data frame containing time-sensitive data if it is available, ensuring that this data is transmitted without competing with other data types. The device can also allocate resources within the data frame to accommodate both time-sensitive data and data from the first access category, enhancing its operational efficiency.
Additionally, the wireless device may include multiple category queues and controllers, allowing it to handle different access categories and links. This configuration enables the device to generate and transmit data frames through various links based on the availability of time-sensitive data. The time-sensitive queue can buffer data according to specific traffic specifications, and it may consist of multiple sub-queues to further optimize data handling. The device also incorporates a mapping unit that assigns incoming media access control (MAC) data to the appropriate queues based on traffic identifiers, ensuring that data is processed and transmitted according to its urgency and category. Overall, the patent outlines a sophisticated approach to managing wireless data transmission, particularly for applications requiring timely delivery.
