Fujitsu had nine patents in internet of things during Q4 2023. The patent filed by Fujitsu Ltd in Q4 2023 is for a terminal apparatus that can activate or deactivate duplication transmission for packet data convergence protocol (PDCP) entities or radio bearers using a bitmap field. The receiver receives a command for this activation or deactivation, while the processor circuitry controls the duplication transmission based on the command. Each bit in the bitmap field corresponds to a specific PDCP entity or radio bearer, allowing for individual control over duplication transmission.

Application: Command indication method and apparatus and information interaction method and apparatus (Patent ID: US20230345583A1)

The patent filed by Fujitsu Ltd. describes a terminal apparatus that receives commands to activate or deactivate duplication transmissions using a bitmap field, with each duplication transmission corresponding to a packet data convergence protocol (PDCP) entity or a radio bearer. The processor circuitry controls the activation or deactivation of these duplication transmissions based on the received commands. The bits in the bitmap field correspond to specific PDCP entities or radio bearers, allowing for granular control over the duplication transmissions.

The claims associated with the patent detail the specific functionalities and configurations of the terminal apparatus. These include the correspondence of bits in the bitmap field to duplication transmission identities, the ranking of PDCP entities configured for duplication transmission, the indication of changing or maintaining duplication transmission states, and the specific type of radio bearers involved. Additionally, a communication method performed by the terminal is outlined, emphasizing the reception of commands for duplication transmission control and the corresponding mapping of bits in the bitmap field to PDCP entities or radio bearers. Overall, the patent focuses on a method and apparatus for efficient control of duplication transmissions in a communication system.
