Abstract

A method by which a UE device and a Node B communicate information such as scheduling information to each other, including a step of sending the information as part of a communication signal instead of padding in the communication signal if the information can be fit by removing all or part of the padding.

Claims

1. A method, comprising:

triggering an information data item if a bit size of the information data item does not exceed a bit size difference between a protocol data unit size and a total bit size of data and header bits for transport without the information data item in the protocol data unit in a wireless communication signal, and

including the triggered information data item in the protocol data unit.

2. A method as in claim 1, wherein the included information data item comprises buffer status bits/report.

3. The method as in claim 1, wherein the included information data item can be any bit size in a predetermined set of bit sizes and no information data item is included if the bit size difference is smaller in bit size than a smallest bit size in the predetermined set of bit sizes.

4. The method as in claim 3, wherein the information data item having a largest bit size smaller than or equal to the bit size difference is included.

5. The method as in claim 3, wherein the method is performed by a wireless communication device and the wireless communication signal is for transmission to another wireless communication device, and wherein there is a fixed relationship between the bit size of the included information data item and the bit size difference, and the fixed relationship is known to both the wireless communication device and the other wireless communication device.

6. The method as in claim 3, wherein a flag is included in the wireless communication signal so as to signal the presence of said information data item as present in the wireless communication signal.

7. The method as in claim 1, wherein the information data item has a fixed size.

8. The method as in claim 1, wherein the included information data item comprises scheduling information bits.

9. The method as in claim 1, wherein the method is performed by a wireless communication device and the wireless communication signal is for transmission to another wireless communication device, and wherein the wireless communication device is a wireless terminal of a radio access network and the other wireless communication device is a user equipment device, and the wireless communication signal conveys a medium access control-high speed protocol data unit.

10. A non-transitory computer readable medium embodying computer program code thereon for execution by a computer processor, wherein said computer program code includes instructions for causing the wireless communication device to perform the method according to claim 1.

11. Apparatus, comprising:

at least one a processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus at least to;

trigger an information data item if a bit size of the information data item does not exceed a bit size difference between a protocol data unit size of data and a total bit size of data and header bits for transport without the information data unit in a wireless communication signal, and

include the triggered information data item in the protocol data unit.

12. The apparatus of claim 11, wherein the included information data item comprises buffer status bits/report.

13. The apparatus of claim 11, wherein the included information data item can be any bit size in a predetermined set of bit sizes and no information data item is included if the bit size difference is smaller in bit size than a smallest bit size in the predetermined set of bit sizes.

14. The apparatus of claim 13, wherein the information data item having a largest bit size smaller than or equal to the bit size difference is included.

15. The apparatus of claim 13, wherein the method is performed by a wireless communication device and the wireless communication signal is for transmission to another wireless communication device, and wherein there is a fixed relationship between the bit size of the included information data item and the bit size difference, and the fixed relationship is known to both the wireless communication device and the other wireless communication device.

16. The apparatus of claim 13, wherein a flag is included in the wireless communication signal so as to signal the presence of said information data item as present in the wireless communication signal.

17. The apparatus of claim 11, wherein the information data item has a fixed size.

18. The apparatus of claim 11, wherein the included information data item comprises scheduling information bits.

19. The apparatus as in claim 11, wherein the method is performed by a wireless communication device and the wireless communication signal is for transmission to another wireless communication device, and wherein the wireless communication device is a wireless terminal of a radio access network and the other wireless communication device is a user equipment device, and the wireless communication signal conveys a medium access control-high speed protocol data unit.

20. A method, comprising:

creating or obtaining an information data item if a bit size of the information data item does not exceed a bit size difference between a bit size capacity of a protocol data unit and a bit size of transport bits for transport in the protocol data unit in a wireless communication signal, and

including the created or obtained information data item into the protocol data unit for transport.
