摘要:
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.

摘要:
A method of operating a wireless transmit receive unit (WTRU) and a WTRU configured to receive a radio link control (RLC)/a medium access control (MAC) header. The header is coded for reduced transmission time interval (RTTI) operation. The header includes a 16-bit cyclic redundancy check (CRC) of an RLC/MAC payload associated with the RLC/MAC header.
摘要:
A method and apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed. A PAN check sequence (PCS) is created, for example using a cyclic redundancy check (CRC) encoding. The PCS is masked with a temporary flow identity (TFI) assigned to a TBF or a mask generated based on the TFI. A data block including the PAN field and the masked PCS is then processed for transmission. The mask may be generated by converting the TFI using an (M, N) code, M being not greater than the number of bits of the PCS and N being the number of bits of the TFI. With this scheme, a TFI may be transmitted in a PAN field without using explicit bits to identify the TBF.

摘要:
A method and apparatus are disclosed for wireless transmission using two or more pulse shaping filters. Wireless transmit/receive units (WTRUs) and network entities are capable of utilizing a narrow band pulse shaping filter, a wideband pulse shaping filter, or both. The network entity and/or the WTRU select a pulse shaping filter to be used and transmits the selection by means of signaling. The signaling may be performed through layer 2/3 messages or by using non-access stratum (NAS) signaling messages.
摘要:
Piggybacked acknowledgement/non-acknowledgement (PAN) bits in unreliable bit positions of a modulated symbol are swapped with data bits located in more reliable bit positions. In addition, a power offset value may be applied to the symbols containing the PAN bits.
