Abstract
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for processing an uplink grant after the last uplink transmission in wireless communication system, the method comprising: transmitting uplink data with a buffer status reporting (BSR); receiving uplink grant after the BSR is transmitted; and discarding the received uplink grant if the received uplink grant is for new transmission and a buffer size of the BSR is set to zero.
Claims6
A method for a user equipment (UE) operating in a wireless communication system, the method comprising:
- transmitting uplink data with a buffer status reporting (BSR) of which a buffer size is set to zero for indicating that the uplink data is last transmitted data;
- receiving uplink grant for new transmission indicating an acknowledgement (ACK) to the last transmitted data in response to the BSR set to zero, after the BSR is transmitted;
- and
- discarding the received uplink grant for the new transmission,
- wherein the UE does not perform uplink transmission when the received uplink grant is discarded, and
- wherein when the UE does not perform uplink transmission, the UE does not generate any Medium Access Control Packet Data Unit (MAC PDU) for uplink transmission even if there is a data available for transmission.
A User Equipment (UE) for operating in a wireless communication system, the UE comprising:
- a Radio Frequency (RF) module;
- and
- a processor operably coupled with the RF module and configured to:
- transmit uplink data with a buffer status reporting (BSR) of which a buffer size is set to zero for indicating that the uplink data is last transmitted data;
- receive uplink grant for new transmission indicating an acknowledgement (ACK) to the last transmitted data in response to the BSR set to zero, after the BSR is transmitted;
- and
- discard the received uplink grant for the new transmission,
- wherein the received uplink grant is for new transmission,
- wherein the processor does not perform uplink transmission when the received uplink grant is discarded, and
- wherein when the processor does not perform uplink transmission, the UE does not generate any Medium Access Control Packet Data Unit (MAC PDU) for uplink transmission even if there is a data available for transmission.
