AI summary

A user equipment (UE) and a base station (BS) are provided. The UE transmits a first uplink signal to the BS based on a current data repetition transmission parameter. After receiving a dynamic indication message from the BS, the UE generates an updated data repetition transmission parameter according to the dynamic indication message. The UE transmits a second uplink signal to the BS based on the updated data repetition transmission parameter.
