摘要： A method (200) is proposed for scheduling, in a radio mobile network (100), serving cell/radio resource allocation pairs (a k ) for transmission of data flows ( f ) using Carrier Aggregation. Each serving cell/radio resource allocation pair comprises a serving cell and a radio resource thereof allocated for transmission of data flows ( f ) using Carrier Aggregation. At each scheduling period ( k ) the method (200) comprises: determining (210-220), among said data flows ( f ), active data flows ( f a) whose transmission is not yet completed at the current scheduling period ( k ), and iterating, for each active data flow ( f a): - determining (225) candidate serving cells (sc,Sa k ) adapted to provide transmission of the active data flows ( f a); - for each radio resource of each candidate serving cell (sc,Sa k ),determining (230) a signal to noise-plus-interference ratio estimate (SINR r k (sc,u)) for that active data flow ( f a); - associating (235), to each candidate serving cell/radio resource pair, a weighting parameter (W) according to said signal to noise-plus-interference ratio estimate (SINR r k (sc,u)) and to an indication of the interference caused to other active data flows ( f a); - determining (240-245), among said candidate serving cell/radio resource pairs, a potential allocation pair (s c *,r*) based on the weighting parameter (W) associated with the candidate serving cell/radio resource pair, and calculating (250) a potential amount (d temp ) of data that can be transmitted by the allocation pairs so far determined and the potential allocation pair, and - identifying (260) said potential allocation pair (s c *,r*) as allocation pair (ak) if (255) said potential amount of data (d temp ) is higher than an overall amount of data (d curr ) that can be transmitted by the allocation pairs so far determined for all the active data flows ( f a).
