Patent ID: 8019375

Claim:
A method of selecting a transport format combination with a mobile station to select a first transport format combination for use in data transmission in a first physical channel in an uplink between the mobile station and a base station from a plurality of first transport format combinations to be set for the first physical channel, and a second transport format combination for use in data transmission in a second physical channel in the uplink from a plurality of second transport format combinations to be set for the second physical channel, said method comprising: the first step of calculating the transmission power of said first physical channel using a first transport format combination with respect to each of said first transport format combinations, comparing the calculated transmission power with the maximum power of said mobile station, and determining whether said mobile station is in a transmission capable state or not based on the result of the comparison; the second step of calculating the sum of the transmission power of said first physical channel and the transmission power of said second physical channel using a first transport format combination and a second transport format combination, respectively, with respect to each of combinations of said first transport format combinations and said second transport format combinations, comparing the calculated sum with the maximum power of said mobile station, and determining whether said mobile station is in the transmission capable state or not based on the result of the comparison; the third step of selecting a first transport format combination from the first transport format combinations wherein said mobile station is in the transmission capable state; the fourth step of selecting a second transport format combination from the second transport format combinations which are included in combinations wherein said mobile station is in the transmission capable state among the combinations including said selected first transport format combination; and the fifth step of transmitting data in said first physical channel and said second physical channel using said selected first transport format combination and said selected second transport format combination, respectively.
