Apparatus and method for transmitting uplink control information on shared channels
View Patent ↗Mobile station applications ( 419 ) may include an SI unit ( 409 ) for piggy backing SI onto data stored in data buffer ( 421 ) and also for adding an indicator to the SI information. The scheduling information and/or incremental control information ( 501 ) is piggy backed onto a data PDU and also has a sequence number ( 503 ) and an indicator field ( 505 ) which is added by the SI unit, such as SI unit ( 409 ), in accordance with the embodiments. The indicator may be a bit map having four bit positions. A bit position having a binary “1” value may be utilized to indicate that a previous SN of SI information remains valid. For example, “0100” of the bit map sequence may indicate that SN # 3 is still valid. The base station or controller may then determine whether to implement or discard an SI information having the indicated SN.
1. A method of operating a mobile station, the method comprising:
appending, by the mobile station, control information to a data packet wherein said data packet has a data packet sequence number;
adding, by the mobile station, a control information sequence number to said control information, said control information sequence number different from said data packet sequence number; and
transmitting, by the mobile station, said data packet in accordance with a resource allocation for said data packet.
2. The method of claim 1 , further comprising:
resending, by the mobile station, said control information a second time if a not acknowledge message is received for said data packet.
3. The method of claim 1 , further comprising:
adding, by the mobile station, a bit map to said control information, said bit map indicating a control information sequence number of a previously transmitted control information wherein said previously transmitted control information is still valid.
4. The method of claim 1 , further comprising:
adding, by the mobile station, a bit map to said control information, said bit map indicating a control information sequence number of a previously transmitted control information wherein said previously transmitted control information is no longer valid and may be discarded.
5. The method of claim 1 , wherein said control information is scheduling information.
6. The method of claim 1 , wherein said control information includes channel quality information.
7. A mobile station comprising:
at least one transceiver;
at least one processor coupled to said transceiver; said transceiver and said processor configured to:
append a control information to a data packet wherein said data packet has a data packet sequence number;
add a control information sequence number to said control information, said control information sequence number different from said data packet sequence number; and
transmit said data packet in accordance with a resource allocation for said data packet.
8. The mobile station of claim 7 , wherein said transceiver and said processor are further configured to:
resend said control information a second time if a not acknowledge message is received for said data packet.
9. The mobile station of claim 7 , wherein said transceiver and said processor are further configured to:
add a bit map to said control information, said bit map indicating a control information sequence number of a previously transmitted control information wherein said previously transmitted control information is still valid.
10. The mobile station of claim 7 , wherein said transceiver and said processor are further configured to:
add a bit map to said control information, said bit map indicating a control information sequence number of a previously transmitted control information wherein said previously transmitted control information is no longer valid and may be discarded.
