Claim 7:
8. A method for a communication device to handle a power headroom report (PHR) for multiple transmission time intervals (TTIs), comprising:
determining a first PHR for a first TTI of a first serving cell according to a first PH level of the first serving cell, wherein the communication device is configured with a second serving cell of a second TTI and a third serving cell of a plurality of third TTIs in the second TTI;
determining a second PHR for the second TTI of the second serving cell according to a second PH level of the second serving cell;
determining a third PHR for a plurality of third TTIs of the third serving cell in the second TTI according to a third PH level of one of the plurality of third TTIs; and
transmitting the first PHR, the second PHR and the third PHR to a network via one of the first serving cell, the second serving cell and the third serving cell;
wherein at least one first serving cell is for performing at least one first UL transmission via a first radio access technology (RAT), and the second serving cell and the third serving cell are for performing at least one second UL transmission via a second RAT;
wherein each length of the plurality of third TTIs is not greater than a half length of the second TTI.
