Apparatus and method for transmitting data in wireless communication system
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting, by a user equipment (UE), data in a wireless communication system, the method comprising: receiving an uplink grant including first transmission time interval (TTI) duration information; transmitting a Medium Access Control Protocol Data Unit (MAC PDU) using the uplink grant, wherein the MAC PDU includes data associated with at least one radio bearer supporting a TTI duration indicated by the first TTI duration information.
1. A method for transmitting, by a user equipment (UE), data in a wireless communication system, the method comprising:
receiving transmission duration information for each of a plurality of radio bearers;
receiving an uplink grant associated with a first transmission duration;
selecting, based on the transmission duration information and the first transmission duration, one or more radio bearers of which data is allowed to be transmitted using the uplink grant; and
transmitting a protocol data unit (PDU) using the uplink grant,
wherein the PDU includes data of the one or more selected radio bearers,
wherein the transmission duration information includes information regarding a plurality of transmission durations allowed for a corresponding one of the plurality of radio bearers, and
wherein each of the one or more selected radio bearers satisfies at least a condition that any one of transmission durations allowed for a corresponding one of the one or more selected radio bearers is the same as the first transmission duration.
2. The method of claim 1 , wherein the PDU does not include data of any radio bearer that does not satisfy the condition.
3. The method of claim 1 , wherein the PDU is transmitted based on the first transmission duration.
4. A user equipment (UE) configured to transmit data in a wireless communication system, the UE comprising:
a transceiver;
at least one processor; and
at least one computer memory that is operably connectable to the at least one processor and that has stored thereon instructions which, when executed, cause the at least one processor to perform operations comprising:
receiving, via the transceiver, transmission duration information for each of a plurality of radio bearers;
receiving, via the transceiver, an uplink grant associated with a first transmission duration;
selecting, based on the transmission duration information and the first transmission duration, one or more radio bearers of which data is allowed to be transmitted using the uplink grant; and
transmitting, via the transceiver, a protocol data unit (PDU) using the uplink grant,
wherein the PDU includes data of the one or more selected radio bearers,
wherein the transmission duration information includes information regarding a plurality of transmission durations allowed for a corresponding one of the plurality of radio bearers, and
wherein each of the one or more selected radio bearers satisfies at least a condition that any one of transmission durations allowed for a corresponding one of the one or more selected radio bearers is the same as the first transmission duration.
5. The UE of claim 4 , wherein the PDU does not include data of any radio bearer that does not satisfy the condition.
6. The UE of claim 4 , wherein the PDU is transmitted based on the first transmission duration.
7. A base station (BS) configured to receive data in a wireless communication system, the BS comprising:
a transceiver;
at least one processor; and
at least one computer memory that is operably connectable to the at least one processor and that has stored thereon instructions which, when executed, cause the at least one processor to perform operations comprising:
transmitting, via the transceiver, transmission duration information for each of a plurality of radio bearers,
transmitting, via the transceiver, an uplink grant associated with a first transmission duration, and
receiving, via the transceiver, a protocol data unit (PDU) using the uplink grant,
wherein the PDU includes data of one or more radio bearers,
wherein the transmission duration information includes information regarding a plurality of transmission durations allowed for a corresponding one of the plurality of radio bearers, and
wherein each of the one or more radio bearers satisfies at least a condition that any one of transmission durations allowed for a corresponding one of the one or more radio bearers is the same as the first transmission duration.
8. The BS of claim 7 , wherein the PDU does not include data of any radio bearer that does not satisfy the condition.
9. The BS of claim 7 , wherein the PDU is received based on the first transmission duration.
