Abstract

A method for transmitting data through a logical channel by a user equipment (UE) in a wireless communication system is disclosed. The method comprises determining whether data for the logical channel exists or not; increasing a token value based on a prioritized Bit Rate (PBR) and a time elapsed since the data becomes available for the logical channel, when the data for the logical channel exists; and transmitting the data or a part of the data through the logical channel, when the token value is greater than 0, wherein when there is no data for the logical channel, the token value is not increased.

Claims

1. A method for transmitting data through a logical channel by a user equipment (UE) in a wireless communication system, the method comprises:

determining whether data for the logical channel exists or not;

increasing a token value based on a prioritized Bit Rate (PBR) and a time elapsed since the data becomes available for the logical channel, when the data for the logical channel exists; and

transmitting the data or a part of the data through the logical channel, when the token value is greater than 0,

wherein, when there is no data for the logical channel, the token value is not increased

2. The method according to claim 1, wherein, when a packet duplication is activated or reactivated or is configured for a radio bearer associated with the logical channel, the data becomes available for the logical channel.

3. The method according to claim 2, wherein, when the packet duplication is deactivated, it is determined that the data for the logical channel does not exist.

4. The method according to claim 1, wherein increasing the token value comprises increasing the token value by a product of the PBR and the time elapsed since the data becomes available for the logical channel.

5. A user equipment (UE) in a wireless communication system, the UE comprising:

a memory; and

at least one processor coupled to the memory and configured to

determine whether data for a logical channel exists or not;

increase a token value based on a prioritized Bit Rate (PBR) and a time elapsed since the data becomes available for the logical channel, when the data for the logical channel exists; and

transmit the data or a part of the data through the logical channel, when the token value is greater than 0,

wherein when there is no data for the logical channel, the token value is not increased.

6. The UE according to claim 5 wherein, when a packet duplication is activated or reactivated or is configured for a radio bearer associated with the logical channel, the data becomes available for the logical channel.

7. The UE according to claim 6, wherein, when the packet duplication is deactivated, it is determined that the data for the logical channel does not exist.

8. The UE according to claim 5, wherein the token value is increased by a product of the PBR and the time elapsed since the data becomes available for the logical channel.
