Patent ID: 6876637

Claim:
A method for rate matching between at least two transport channels included within a composite channel, said method comprising at least one rate matching step for each transport channel (i), a rate matching ratio (RF i ) being applied to each transport channel (i), said rate matching ratio (RF i ) being equal to the product of a rate matching factor (RM i ) specific to said transport channel (i) and a scale factor (LF), said scale factor (LF) being common to the set of said transport channels of said composite channel, each of said transport channels being transmitted for at least one associated transmission time interval (TTI), each of said transmission time intervals (TTI) having a duration specific (F i ) to each (i) of said transport channels, at least two of said transport channels having transmission time channels (TTI) with distinct duration, characterized in that it comprises successive steps of: defining ( 301 ), for said composite channel, a list of at least two transport channels ordered in descending order of the duration of their respective transmission time interval (TTI), said ordered list of transport channels being able to include at least one transport channel not transporting any data for at least one associated transmission time interval (TTI), determining ( 302 ), for said composite channel, at least two so-called global intervals for said ordered list of transport channels, said determined global intervals following each other in time, each of said determined global intervals corresponding: either to a transmission time interval (TTI) associated with the first transport channel of said ordered list conveying data for said associated transmission time interval (TTI), or, in case none of the transport channels of said ordered list is transporting any data, to the smallest transmission time interval, assigning ( 303 ) a scale factor (LF) to each determined global interval, said scale factor being constant for the duration of each determined global interval, at least two assigned scale factors having distinct values (LFG ((A,0)) , LFG ((A,2)) ) for at least two global intervals.
