<p>Disclosed are an uplink data transmission method and device. The method includes: UE determining whether uplink data to be sent is the last data packet in the cache of the UE; adding an identifier in the uplink data to be sent, wherein the identifier is used for indicating that the uplink data to be sent is the last data packet in the cache of the UE; and sending to an eNB the uplink data to be sent. The present invention can avoid that the eNB feeds back the authorization of a new data packet to the UE after the UE transmits the last data packet in the cache, thus avoiding resource waste.</p> |
