Method and apparatus for providing piggybacked positive acknowledgement/negative acknowledgement field indicator and a polling indicator
A method and apparatus of providing a piggybacked positive acknowledgement/negative acknowledgement (ACK/NACK) (PAN) field indicator (PANI) and a polling indicator are disclosed. A combined field of a PANI bit, a relative reserved block period (RRBP) bit and an EGPRS supplementary polling (ES/P) field may indicate a polling scheme and a presence of a PAN field. Alternatively, the presence of the PAN field in the data block may be indicated by using a specific training sequence. Alternatively, a forward error correction (FEC) coding may be performed on the data block including the header, and the presence of the PAN field may be indicated by scrambling the encoded bits corresponding the header with a specific scrambling sequence. Alternatively, a header check sequence (HCS) may be generated and the presence of the PAN field is indicated by mixing a predetermined sequence with the HCS.

4. The method of claim 1 , wherein the TBF is received via a GSM/EDGE radio access network (GERAN).
5. A wireless transmit/receive unit (WTRU) for fast acknowledgement/non-acknowledgement reporting (FANR) operation, the WTRU comprising:
a transceiver configured to receive a temporary block flow (TBF) including a radio link control/medium access control (RLC/MAC) header and a corresponding RLC/MAC data block, wherein the RLC/MAC header includes a four-bit sequence simultaneously indicating both information regarding a positive acknowledgement/negative acknowledgement (ACK/NACK) polling scheme and a presence or absence of a piggybacked ACK/NACK (PAN) field in the corresponding RLC/MAC data block, wherein one bit of the four-bit sequence is assigned to indicate the presence or absence of the PAN field in the corresponding RLC/MAC data block, and each of a plurality of bit combinations of the bit assigned for indicating the presence or absence of the PAN field and remaining three bits of the four-bit sequence indicates a different combination of the ACK/NACK polling scheme and the presence or absence of the PAN field in the corresponding RLC/MAC data block; and

6. The WTRU of claim 5 , wherein the information regarding the ACK/NACK polling scheme in the four-bit sequence includes a relative reserved block period (RRBP) indicator and an evolved general packet radio service (E-GPRS) supplementary polling (ES/P) indicator.
7. The WTRU of claim 5 , wherein the PAN field in the RLC/MAC data block and data in the RLC/MAC data block are addressed to different WTRUs.
8. The WTRU of claim 5 , wherein the TBF is received via a GSM/EDGE radio access network (GERAN).
9. A method of fast acknowledgement/non-acknowledgement reporting (FANR) operation, the method comprising:
generating a radio link control/medium access control (RLC/MAC) header including a four-bit sequence simultaneously indicating information regarding a positive acknowledgement/negative acknowledgement (ACK/NACK) polling scheme and a presence or absence of a piggybacked ACK/NACK (PAN˜field in a corresponding RLC/MAC data block, wherein one bit of the four-bit sequence is assigned to indicate the presence or absence of the PAN field in the corresponding RLC/MAC data block, and each of a plurality of bit combinations of the bit assigned for indicating the presence or absence of the PAN field and remaining three bits of the four-bit sequence indicates a different combination of the ACK/NACK polling scheme and the presence or absence of the PAN field in the corresponding RLC/MAC data block; and
