摘要： The invention proposes the method and device for delivery BSR information to assist efficient scheduling. It introduces at least one additional table (also called extended table) which indicates the buffer statues corresponding to the higher data rates than the existing table. The use of the at least one additional table is identified by new identification(s), more specifically one or more Logical channel ID. The signaling uses MAC layer signaling as in ReI.8/9. In an embodiment of the present invention, the new MAC CE is designed to guarantee the co-existence of ReI.8/9 and ReI.10 buffer status reporting depending on low or high data rates.
