Method and apparatus for indicating a temporary block flow to which a piggybacked acknowledgement/non-acknowledgement field is addressed

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 Tl. A data block including the PAN field and the masked PCS is then processed for transmission, The mask may be generated by converting the TF1 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 TFl. With this scheme, a TFl may be transmitted in a PAN field without using explicit bits to identify the TBF. Go h ci I --
