Method of processing data in a medium access control (MAC) layer
View Patent ↗A method of processing data in a Medium Access Control (MAC) layer through which at least one first channel is mapped to a second channel in a transmitting end of a wireless communication system is disclosed. More specifically, a MAC layer data block is configured by including at least one higher layer data block received through the at least one first channel and adding a header thereto which includes at least one field which indicates at least two types of information. Furthermore, the MAC layer data block is tranferred to a lower layer through the second channel.
1. A method of processing data in a Medium Access Control (MAC) layer through which at least one first channel is mapped to a second channel in a transmitting side of a wireless communication system, the method comprising:
configuring a MAC layer data block by including at least one higher layer data block received through the at least one first channel and including a header comprising one or more fields, wherein a single field of the one or more fields identifies at least two types of information used for identifying the at least one higher layer data block from the MAC layer data block, wherein the at least two types of information comprise logical channel information and a size of the at least one higher layer data block; and
transferring the MAC layer data block to a lower layer through the second channel.
2. The method of claim 1 , wherein the first channel is a logical channel and the second channel is a transport channel.
3. The method of claim 2 , wherein the at least two types of information further comprise a MAC-d flow.
4. The method of claim 3 , wherein the transport channel is an Enhanced Dedicated Channel (E-DCH).
5. The method of claim 1 , wherein each of the one or more fields is included for each logical channel.
6. The method of claim 1 , wherein the logical channel information is a logical channel identification.
7. The method of claim 6 , further comprising adding one common logical channel identification to all higher layer data blocks transmitted via a same logical channel.
8. The method of claim 1 , wherein the header further comprises a field indicating a number of higher layer data blocks transmitted via the at least one first channel included in the MAC layer data block, wherein the at least one first channel is a logical channel.
9. The method of claim 1 , further comprising:
indexing an amount of higher layer data blocks transmitted via the at least one first channel into smaller amount sizes; and
inserting the index into the header.
10. The method of claim 9 , wherein the smaller amount sizes representing each logical channel is different.
11. A method of processing data in a Medium Access Control (MAC) layer through which at least one first channel is mapped to a second channel in a receiving side of a wireless communication system, the method comprising:
receiving a MAC layer data block from a lower layer through the second channel, wherein the MAC layer data block comprises a header including one or more fields, wherein a single field of the one or more fields identifies at least two types of information used for identifying the at least one higher layer data block from the MAC layer data block, wherein the at least two types of information comprise logical channel information and a size of the at least one higher layer data block; and
transferring the at least one higher layer data block in the MAC layer data block to a higher layer via the at least one first channel using the at least two types of information in the single field.
12. The method of claim 11 , wherein the at least one first channel is a logical channel and the second channel is a transport channel.
13. The method of claim 12 , wherein the at least two types of information further comprise a MAC-d flow.
14. The method of claim 13 , wherein the transport channel is an Enhanced Dedicated Channel (E-DCH).
15. The method of claim 11 , wherein each of the one or more fields is included for each logical channel.
16. The method of claim 11 , wherein the logical channel information is a logical channel identification.
17. The method of claim 16 , further comprising adding one common logical channel identification to all higher layer data blocks transmitted via a same logical channel.
18. The method of claim 11 , wherein the header further comprises a field indicating a number of higher layer data blocks transmitted via the at least one first channel included in the MAC layer data block, wherein the at least one first channel is a logical channel.
19. A method of processing data in a Medium Access Control (MAC) layer of a user equipment (UE) through which at least one first channel is mapped to a second channel in a transmitting end of a wireless communication system, the method comprising:
configuring a MAC layer data block by including at least one higher layer data block received through the at least one first channel and including a header comprising one or more fields, wherein a single field of the one or more fields identifies at least two types of information used for identifying the at least one higher layer data block from the MAC layer data block, wherein the at least two types of information comprise logical channel information and a size of the at least one higher layer data block; and
transferring the MAC layer data block to a lower layer through the second channel.
20. The method of claim 19 , wherein the at least one first channel is a logical channel and the second channel is a transport channel.
