Classification: CPC H | IPC H

Claim 0:
1. A method for transmitting signals by a user equipment (UE) in a wireless communication system, the method comprising:
configuring first and second type logical channel groups;
receiving a first uplink grant from a network; and
transmitting buffer size information based on the first uplink grant to the network,
wherein, based on determining that the first uplink grant is allowed to be used for transmission of buffer size information of the second logical channel group, the buffer size information includes the buffer size information of the first and second logical channel groups regardless of whether there is uplink data is available for the logical channel which belongs to the second logical channel group or not,
wherein, based on determining that the first uplink grant is not allowed to be used for transmission of buffer size information of the second logical channel group, the buffer size information includes the buffer size information of the first logical channel group,
wherein the method further comprising:
receiving a second uplink grant from the network, as a response of the buffer size information; and
transmitting an uplink data signal using the second uplink grant to the network,
when the first uplink grant is allowed to be used for transmission of buffer size information of the second logical channel group, the second uplink grant is used for transmitting logical channels belonging to the first and second logical channel groups,
when the first uplink grant is not allowed to be used for transmission of buffer size information of the second logical channel group, the second uplink grant is used for transmitting logical channels belonging to the first logical channel group.
