  • determining if a E-DCH buffer is empty;

    transmitting to the base station scheduling information (SI), wherein the SI includes a total E-DCH buffer status (TEBS) equal to zero when the E-DCH buffer is determined to be empty;

    determining if a hybrid automatic repeat request (HARQ) buffer is empty;
