Abstract
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for configuring uplink grants over multiple subframes in a wireless communication system, the method comprising: receiving an uplink grant from an eNodeB (eNB), wherein the uplink grant is valid during a specific time duration; transmitting data using the uplink grant when the data is generated during the specific time duration; and discarding the uplink grant when the specific time duration is passed.
Claims13
A method for a User Equipment (UE) operating in a wireless communication system, the method comprising:
- receiving an uplink grant from an eNodeB (eNB) when there is no uplink data to be generated, wherein the uplink grant is valid during a specific time duration;
- transmitting data using the uplink grant when the data is generated during the specific time duration;
- and
- discarding the uplink grant when the specific time duration is passed when the data has not been generated during the specific time duration,
- wherein the uplink grant includes an indication that the uplink grant is for data which the UE expects to be generated.
A method for a User Equipment (UE) operating in a wireless communication system, the method comprising:
- starting a timer when an uplink grant is received from an eNodeB (eNB) and there is no uplink data to be generated, wherein the uplink grant is valid while the timer is running;
- transmitting data using the uplink grant when the data is generated while the timer is running;
- and
- discarding the uplink grant when the timer expires when the data has not been generated while the timer is running,
- wherein the uplink grant includes an indication that the uplink grant is for data which the UE expects to be generated.
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:
- receive an uplink grant from an eNodeB (eNB) when there is no uplink data to be generated, wherein the uplink grant is valid during a specific time duration;
- transmit data using the uplink grant when the data is generated during the specific time duration;
- and
- discard the uplink grant when the specific time duration is passed when the data has not been generated during the specific time duration,
- wherein the uplink grant includes an indication that the uplink grant is for data which the UE expects to be generated.
