Abstract

A method, system and computer program product for the transmission of data from a transmitter to receiver. The present invention is directed to improving data transmission. To this end, the transmission of data is accelerated, and an inband-signaling of information is carried out on an MAC-layer plane, wherein the information is particularly relevant to the base station (BS).

First claim

The invention claimed is:

1. One or more non-transitory computer readable media including instructions, which when executed by a user equipment (UE), causes the UE to:
generate, by a Media Access Control (MAC) entity of the UE, a Buffer Status Report relevant to a base station, wherein the Buffer Status Report indicates an amount of data for transmission in a buffer of a transport channel from the UE to the base station; and
generate, at the MAC entity based on an uplink scheduling allocation, at least one signaling transport block to include the Buffer Status Report for transmission to the base station, wherein the signaling transport block is multiplexed with data transport blocks and transmitted on the transport channel.

2. The one or more non-transitory computer readable media of claim 1 wherein the Buffer Status Report is transmitted in accordance with an instruction from the base station.

3. The one or more non-transitory computer readable media of claim 2 wherein the instruction requests the Buffer Status Report on multiple radio bearers or logical channels on the transport channel.

4. The one or more non-transitory computer readable media of claim 1 wherein the transport channel is a dedicated transport channel.

5. The one or more non-transitory computer readable media of claim 1 wherein the signaling transport block includes padding of dummy bits.

6. The one or more non-transitory computer readable media of claim 1 , wherein:
the at least one signaling transport block includes a MAC Service Data Unit (SDU); and
the Buffer Status Report from the UE is transmitted within the MAC SDU.

7. The one or more non-transitory computer readable media of claim 1 , wherein the Buffer Status Report is transmitted based upon at least one Radio Resource Control (RRC) message from the base station.

8. A user equipment (UE) comprising:
a control plane to:
generate, at a Media Access Control (MAC) layer of the UE, a Buffer Status Report relevant to a base station, wherein the Buffer Status Report indicates an amount of data for transmission in a buffer of a transport channel from the UE to the base station,
generate at least one signaling transport block to include the Buffer Status Report for transmission to the base station based on an uplink scheduling allocation, and
multiplex the signaling transport block with data transport blocks; and

a transmitter to transmit, on a transport channel, the signaling transport block including the Buffer Status Report to the base station.

9. The user equipment of claim 8 wherein the control plane is adapted to receive an instruction from the base station, and in accordance with the instruction, to generate the Buffer Status Report.

10. One or more non-transitory computer readable media including instructions, which when executed by a base station (BS), causes the BS to:
control receipt of at least one signaling transport block from a user equipment (UE) according to an uplink scheduling allocation, wherein the signaling transport block is multiplexed with data transport blocks and transmitted on the transport channel; and
extract, by a MAC layer entity, a Buffer Status Report from the signaling transport block, wherein the Buffer Status Report indicates an amount of data for transmission in a buffer of a transport channel from the UE to the base station.

11. The one or more non-transitory computer readable media of claim 10 , wherein the BS, in response to execution of the instructions, is to transmit an instruction to the user equipment to transmit back to the base station the Buffer Status Report.

12. The one or more non-transitory computer readable media of claim 11 wherein the instruction requests the Buffer Status Report on multiple radio bearers or logical channels on the transport channel.

13. The one or more non-transitory computer readable media of claim 10 wherein the transport channel is a dedicated transport channel.

14. The one or more non-transitory computer readable media of claim 10 wherein the signaling transport block includes padding of dummy bits.

15. A base station comprising:
a transceiver to receive, according to an uplink scheduling allocation, at least one signaling transport block from a user equipment (UE) that includes a Buffer Status Report, wherein the Buffer Status Report indicates an amount of data for transmission in a buffer of a transport channel from the UE to the base station, and wherein the signaling transport block is multiplexed with data transport blocks and transmitted on the transport channel; and
a Media Access Control (MAC) entity to extract the Buffer Status Report from the signaling transport block.

16. The base station of claim 15 wherein a radio network control entity is adapted to cause the transceiver to transmit an instruction to the user equipment to transmit back to the base station the Buffer Status Report.
