A method for acknowledging radio link control, RLC, data packet transmission, comprising: determining, by an RLC acknowledged mode, AM, entity sender, if a RLC data packet to be transmitted is an independent RLC data packet by determining if a counter PDU WITHOUT POLL is 1, and only the RLC data packet exists in a buffer, then determining,by the RLC AM entity sender, that the RLC data packet is an independent RLC data packet; if the RLC AM entity sender determines that the RLC data packet to be transmitted is an independent RLC data packet sending, by the RLC AM entity sender, the independent RLC data packet to an RLC AM entity receiver through a sender medium access control, MAC, entity and a receiver MAC entity, wherein the independent RLC data packet comprises first indication information, and the first indication information is used to instruct the RLC AM entity receiver not to feed back acknowledgment information of the independent RLC data packet; and sending, by the RLC AM entity sender a second indication information to the sender MAC entity, wherein the second indication information is used to instruct the sender MAC entity to feed back local acknowledgment information of the independent RLC data packet to the RLC AM entity sender; receiving, by the RLC AM entity sender, the local acknowledgment information of the independent RLC data packet that is fed back by the sender MAC entity, wherein the local acknowledgment information of the independent RLC data packet is generated by the sender MAC entity according to acknowledgment information of a MAC data packet to which the independent RLC data packet belongs, wherein the acknowledgement information of the MAC data packet is fed back by the receiver MAC entity; wherein the local acknowledgment information of the independent RLC data packet is fed back by the sender MAC entity according to the obtained second indication information. determining, by an RLC acknowledged mode, AM, entity sender, if a RLC data packet to be transmitted is an independent RLC data packet by determining if a counter PDU WITHOUT POLL is 1, and only the RLC data packet exists in a buffer, then determining,by the RLC AM entity sender, that the RLC data packet is an independent RLC data packet; if the RLC AM entity sender determines that the RLC data packet to be transmitted is an independent RLC data packet sending, by the RLC AM entity sender, the independent RLC data packet to an RLC AM entity receiver through a sender medium access control, MAC, entity and a receiver MAC entity, wherein the independent RLC data packet comprises first indication information, and the first indication information is used to instruct the RLC AM entity receiver not to feed back acknowledgment information of the independent RLC data packet; and sending, by the RLC AM entity sender a second indication information to the sender MAC entity, wherein the second indication information is used to instruct the sender MAC entity to feed back local acknowledgment information of the independent RLC data packet to the RLC AM entity sender; receiving, by the RLC AM entity sender, the local acknowledgment information of the independent RLC data packet that is fed back by the sender MAC entity, wherein the local acknowledgment information of the independent RLC data packet is generated by the sender MAC entity according to acknowledgment information of a MAC data packet to which the independent RLC data packet belongs, wherein the acknowledgement information of the MAC data packet is fed back by the receiver MAC entity; wherein the local acknowledgment information of the independent RLC data packet is fed back by the sender MAC entity according to the obtained second indication information.
