User equipment, method for determining resource, method for reporting resource, and system for distributing resource

A user equipment (UE) operable of transmission on multiple carriers, the UE comprising:

• a processor configured to set a happy bit for each carrier;
• and
• a transmitter configured to transmit the happy bit,
• wherein the happy bit is set, for each carrier, to “unhappy” in a situation where following first, second, and third conditions are met:
• the first condition indicating that transmission data on the carrier reaches maximum transmission data allowed by a current service grant (SG) on the carrier;
• the second condition indicating that the UE has enough transmission power available to improve a data transmission rate on the carrier;
• and
• the third condition indicating that, in a configured time period, the carrier together with at least one of other carriers among the multiple carriers are incapable of finishing transmission of total buffer data transmitted with a product of the current SG and a ratio of active processes to a total number of processes on the carrier plus a product of a current SG and a ratio of active processes to a total number of processes on each of the at least one of the other carriers.

A communication system, comprising:

• a user equipment (UE) capable of data transmission on multiple carriers and capable of communicatively connecting with a base station,
• wherein the UE is configured to set a happy bit for each carrier and to transmit the happy bit to the base station,
• wherein the happy bit is set, for each carrier, to “unhappy” in a situation where following first, second, and third conditions are met:
• the first condition indicating that transmission data on the carrier reaches maximum transmission data allowed by a current service grant (SG) on the carrier;
• the second condition indicating that the UE has enough transmission power available to improve a data transmission rate on the carrier;
• and
• the third condition indicating that, in a configured time period, the carrier together with at least one of other carriers among the multiple carriers are incapable of finishing transmission of total buffer data transmitted with a product of the current SG and a ratio of active processes to a total number of processes on the carrier plus a product of a current SG and a ratio of active processes to a total number of processes on each of the at least one of the other carriers.
