Feedback method for grant-free uplink transmission
A recently granted patent (Publication Number: US11929836B2) discloses a feedback method for grant-free uplink transmission in a wireless communication network. The method involves allocating a group of user equipment (UE) devices with transmission cycles meeting specific conditions to the same UE group. The access network device receives uplink data from a UE in the group and sends downlink feedback information in a common search space, indicating the success or failure of the uplink transmission for the entire UE group. The feedback information can include details about individual UEs within the group, such as transmission success or failure of specific data blocks.
Furthermore, the patent describes a feedback method applicable to a target UE within a UE group, obtained by allocating UEs meeting certain transmission cycle criteria. The target UE sends uplink data to the access network device and receives downlink feedback information in a common search space, indicating the success or failure of the uplink transmission for the entire UE group. The feedback information can provide detailed insights into the success or failure of specific data blocks within the transmission. The patent also includes a feedback device and a computer-readable storage medium storing instructions for implementing the disclosed methods, enhancing the efficiency and reliability of grant-free uplink transmission in wireless communication networks.
