Abstract

A method for allocating uplink and downlink physical channels to improve throughput of a wireless access system is disclosed. A method for allocating channels to optimize a wireless access system which supports radio frequencies comprises configuring one or more physical channels in a transmitter; allocating first physical channels to a receiver considering features of the one or more physical channels; and transmitting one or more control channels to the receiver through a predetermined physical channel of the first physical channels, the control channels including configuration information of the first physical channels allocated to the receiver.

Claims

1-21. -21. (canceled)

22. A method for receiving physical channels allocated to optimize a wireless access system which supports radio frequencies, the method comprising:

receiving, by an user equipment (UE) from a base station (BS), one or more physical downlink control channels (PDCCHs) only on a primary physical channel, wherein the one or more PDCCHs comprise an indication field of scheduled physical channel and a carrier of the primary physical channel is belonging to a multi-carrier aggregated with plurality of carriers; and

receiving, by the UE from the BS, a downlink data through a second physical channel which is comprised in the multi-carrier and indicated by the indication field.

23. The method according to claim 22, wherein the one or more PDCCHs further comprise control information of the multicarrier.

24. The method according to claim 23, wherein the indication field represents what physical channel of the multi-carrier is allocated to the UE.

25. The method according to claim 23, wherein a maximum number of the physical channel which is allocated to the UE is determined according to a level of the UE.

26. The method according to claim 25, wherein the level of the UE is classified by ability of the UE that controlling a number of physical channels simultaneously.

27. The method according to claim 23, wherein the primary physical channel and the secondary physical channel are radio frequencies which are component carrier.

28. The method according to claim 23, further comprising:

transmitting a physical uplink control channel (PUCCH) comprising control information only on the primary physical channel.

29. The method according to claim 22, wherein if the downlink data is an voice over internet protocol (VoIP) data, the downlink data is transmitted only on the primary physical channel.

30. A method for performing feedback of channel status information, the method comprising:

transmitting a physical uplink control channel (PUCCH) comprising control information only on a primary physical channel, wherein a carrier of the primary physical channel is belonging to a multi-carrier aggregated with plurality of carriers; and

transmitting a physical uplink shared channel (PUSCH) comprising uplink data on a secondly physical channel of the multi-carrier.

31. The method according to claim 30, further comprising:

receiving downlink data on the second physical channel, wherein the control information is related with the second physical channel.

32. The method according to claim 30, wherein if the uplink data is an voice over internet protocol (VoIP) data, the uplink data is transmitted only on the primary physical channel.

33. The method according to claim 30, wherein a maximum number of the physical channel which is allocated to the UE is determined according to a level of the UE.

34. The method according to claim 33, wherein the level of the UE is classified by ability of the UE that controlling a number of physical channels simultaneously.

35. An user equipment (UE) for receiving physical channels allocated to optimize a wireless access system which supports radio frequencies, the UE configured for:

receiving, from a base station (BS), one or more physical downlink control channels (PDCCHs) only on a primary physical channel, wherein the one or more PDCCHs comprise an indication field of scheduled physical channel and a carrier of the primary physical channel is belonging to a multi-carrier aggregated with plurality of carriers; and

receiving, from the BS, a downlink data through a second physical channel which is comprised in the multi-carrier and indicated by the indication field,

wherein the indication field represents what physical channel of the multi-carrier is allocated to the UE.

36. The user equipment according to claim 35, wherein the one or more PDCCHs further comprise control information of the multicarrier.

37. The user equipment according to claim 36, wherein a maximum number of the physical channel which is allocated to the UE is determined according to a level of the UE and the level of the UE is classified by ability of the UE that controlling a number of physical channels simultaneously.

38. The user equipment according to claim 36, wherein if the downlink data is an voice over internet protocol (VoIP) data, the downlink data is transmitted only on the primary physical channel.

39. An user equipment (UE) for performing feedback of channel status information, the UE configured for:

transmitting a physical uplink control channel (PUCCH) comprising control information only on a primary physical channel, wherein a carrier of the primary physical channel is belonging to a multi-carrier aggregated with plurality of carriers; and

transmitting a physical uplink shared channel (PUSCH) comprising uplink data on a secondly physical channel of the multi-carrier.

40. The user equipment according to claim 39, wherein if the uplink data is an voice over internet protocol (VoIP) data, the uplink data is transmitted only on the primary physical channel.

41. The user equipment according to claim 39, wherein a maximum number of the physical channel which is allocated to the UE is determined according to a level of the UE and the level of the UE is classified by ability of the UE that controlling a number of physical channels simultaneously.
