Sidelink communication method using consecutive-slots transmission
The granted patent US12041638B2 outlines a method and apparatus for sidelink communication, focusing on efficient transmission over shared spectrum channels. The method involves a terminal device performing channel listening to identify idle channels. Upon detecting idle channels, the device transmits a signal over a first sidelink channel using a consecutive-slots transmission technique. This technique allows for the transmission of data across multiple consecutive time slots, with specific configurations for physical sidelink feedback channels (PSFCH) and control information. The claims detail various configurations of the first sidelink channel, including the inclusion of second-stage sidelink control information (SCI) and multiple PSFCHs, which facilitate feedback associated with a physical sidelink shared channel (PSSCH).
Additionally, the patent describes an apparatus that comprises a processor and non-transitory computer-readable storage media. The stored programming instructions enable the apparatus to perform the same channel listening and transmission operations as described in the method claims. The apparatus is designed to handle multiple pieces of second-stage SCI and manage time-domain resources effectively across the consecutive time slots. The claims emphasize the adaptability of the system to include various configurations of feedback channels and control information, enhancing the efficiency and reliability of sidelink communications in shared spectrum environments.
