Abstract: A radio link control (RLC) entity of a transmitting device receives a first RLC service data unit (SDU) from an upper layer of the transmitting device. If the RLC entity receives, from the upper layer, a discard indication to discard the first RLC SDU, the RLC entity checks whether the first RLC SDU has been submitted to a lower layer of the transmitting device. The RLC entity discards the first RLC SDU if neither the first RLC SDU nor a segment of the first RLC SDU has been submitted to the lower layer.

Abstract: A method for a User Equipment (UE) operating in a wireless communication system including a Primary Cell (PCell) and a first Secondary Cell (SCell) with a Physical Uplink Control Channel (PUCCH) resource. The method includes receiving a parameter included in information about a second SCell without the PUCCH resource. The parameter indicates that a Hybrid Automatic Repeat Request (HARQ) feedback of the second SCell is to be sent on the first SCell. The method further includes transmitting the HARQ feedback of the second SCell to the first SCell.
