Patent ID: 8243697

Claim:
A method of generating a data block for a plurality of uplink frequencies, the data block including a header and a data field, the method comprising: determining a size of the data field of the data block so that each data block matches a minimum of a first amount of data and second amount of data, the first amount of data being allowed to be transmitted by a first grant on a first uplink frequency, the second amount of data being allowed to be transmitted by a second grant on a second uplink frequency; determining whether an amount of data in pre-generated data blocks is less than eight times the minimum of the first amount of data and the second amount of data; and pre-generating additional data blocks only if the amount of data in the pre-generated data blocks is less than eight times the minimum of the first amount of data and the second amount of data so that a sum of the amount of the pre-generated data blocks and an amount of the additional data blocks becomes equal to eight times the minimum of the first amount of data and the second amount of data.
