Application: Systems and methods for lte operation in unlicensed bands (Patent ID: US20240107554A1)
The patent filed by InterDigital Inc. discloses systems, devices, and methods for determining clear channel assessment occasions in wireless communication. The techniques involve conducting clear channel assessment processes on a channel during these occasions to determine its availability, sending an uplink transmission via the channel if it is available, and repeating the assessment if the channel is found to be unavailable. The wireless transmit/receive unit (WTRU) described in the patent includes a transceiver for data transmission, a processor for determining transmission and assessment timings based on received control information, and conducting the channel assessments accordingly.
The patent claims detail the configuration and operation of the WTRU, including the reception of downlink control information specifying UL grants and parameters for channel assessment occasions, the determination of transmission and assessment timings based on this information, and the performance of channel assessments to decide on transmission. The patent also covers scenarios where the channel is unlicensed, the reception of DCI indicating blocks of time periods, and the decoding of group DCI with Radio Network Temporary Identifiers. Overall, the patent focuses on optimizing the use of available channels for efficient wireless communication by conducting timely and accurate channel assessments before sending transmissions.
