AI Technical Summary
In wireless communication systems, particularly in 5G networks, there is a need for efficient cancellation of uplink transmission resources to prevent unnecessary energy consumption and interference, which existing technologies do not adequately address.
A user equipment (UE) is configured to receive configuration information for a physical downlink control channel (PDCCH) and downlink control information (DCI), where the DCI indicates time-frequency resources for cancelling uplink transmission, with the subcarrier spacing determined by the downlink bandwidth part of the cell, allowing for cancellation of specific resources including symbols for physical broadcast channels and synchronization signals, and the UE determines the number of symbols based on monitoring periodicity or predetermined values.
The UE effectively cancels uplink transmission as indicated, reducing energy consumption and preventing interference with other user equipment and the base station, thereby optimizing resource allocation and system performance.
