Embodiments of this application provide a communication method, a terminal and a base station. The method includes: receiving, by a terminal, a scheduling request resource configuration sent by a base station, where the scheduling request resource configuration indicates an uplink resource type or logical channel information; and sending, by the terminal, a scheduling request to the base station via a target scheduling request resource based on the scheduling request resource configuration and uplink data, where the target scheduling request resource indicates a target uplink resource type, and the scheduling request resource configuration includes the target scheduling request resource. In the embodiments of this application, when diversity of the uplink data is considered, the base station configures different scheduling request resources for different service characteristics, and the terminal selects different scheduling request resources for different service characteristics, to improve effectiveness of uplink service transmission.
