METHOD AND DEVICE FOR DELIVERY OF BSR INFORMATION TO ASSIST EFFICIENT SCHEDULING
First Claim
Patent Images
1. A method in a UE of reporting BSR to an eNodeB dominating said UE comprising:
- determining whether BSR for at least one LCG with larger buffer size needs to be reported, said LCG with larger buffer size having a buffer size larger than a predetermined value and said larger buffer size needs at least one additional table for report, said at least one additional table indicating the buffer status corresponding to a larger buffer size than Rel. 8/9 table;
if the BSR for said at least one LCG with larger buffer size needs to be reported, generating the BSR for said at least one LCG with larger buffer size with an index referring to said at least one additional table;
reporting said generated BSR to said eNodeB.

Abstract
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.

8. A method in an eNodeB dominating a UE of processing BSR from said UE comprising:
-
receiving BSR from said UE; determining whether said received BSR is the BSR for at least one LCG with larger buffer size according to the LCID or related bits in the MAC control element derived from said received BSR, said LCG with larger buffer size having a buffer size larger than a predetermined value and said larger buffer size needs at least one additional table for report, said at least one additional table indicating the buffer status corresponding to a larger buffer size than Rel. 8/9 table; if said BSR for at least one LCG with larger buffer size is used, obtaining the buffer size according to said BSR and at least one additional table, and scheduling UL resources for said UE according to said buffer size.

9. A first device in a UE of reporting BSR to an eNodeB dominating said UE comprising:
-
a first determining means configured to determine whether BSR for at least one LCG with larger buffer size needs to be reported, said LCG with larger buffer size having a buffer size larger than a predetermined value and said larger buffer size needs at least one additional table for report; a generating means configured, if the BSR for said at least one LCG with larger buffer size needs to be reported, to generate the BSR for said at least one LCG with larger buffer size with an index referring to said at least one additional table, said at least one additional table indicating the buffer status corresponding to larger buffer size than Rel. 8/9 table; reporting means configured to report said generated BSR to said eNodeB. - View Dependent Claims (10, 11, 12, 13, 14)

15. A second device in an eNodeB dominating a UE of processing BSR from said UE comprising:
a receiver configured to receive BSR from said UE; a second determining means configured to determine whether said received BSR is the BSR for at least one LCG with larger buffer size according to the LCID or related bits in the MAC control element derived from said received BSR, said LCG with larger buffer size having a buffer size larger than a predetermined value; a scheduler configured, if said BSR for at least one LCG with larger buffer size is used, to obtain the buffer size according to said BSR and at least one additional table, and to schedule UL resources for said UE according to said buffer size, said at least one additional table indicating the buffer status corresponding to higher data rates than Rel. 8/9 table.
