METHOD AND APPARATUS FOR INDICATING A TEMPORARY BLOCK FLOW USING A PIGGYBACKED ACK/NACK FIELD

Abstract

The invention claims a method and apparatus for transmitting and receiving a PAN. also claims a method and apparatus for indicating a PAN field addressed to TBF. further claims a receiving process the receiving process can greatly reduce the error acceptable probability of not correctly received PAN it does not reduce the PAN probability of accepting correctly received. emitting station generates a PAN check sequence (PCS) and performs a channel coding on a PAN field and the PCS. the emitting station using a TBF-specific scrambling code to scramble the encoded bits of the PAN field and the PCS. Because of the scrambling if the data block is received by an intended station will through the PCS decoding at the receiving station and if the data block is received by an intended receive station while the PCS decoding will fail. Alternatively the scrambling may be performed before the channel coding. Alternatively the emitting station may combine the PAN field and a temporary flow identity (TFI) to generate a PCS.

A method and an apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed. A method and apparatus of performing receive processing to reduce the probability of false acceptance of erroneous PANs are also disclosed. A transmit station generates a PAN check sequence (PCS) and performs a channel coding on a PAN field and the PCS. The transmit station scrambles the encoded bits of the PAN field and the PCS with a TBF-specific scrambling code. Because of the scrambling the PCS decoding at a receive station will pass if the data block is received by an intended receive station while the PCS decoding will fail if received by a non-intended receive station. Alternatively the scrambling may be performed before the channel coding. Alternatively the transmit station may combine the PAN field and a temporary flow identity (TFI) to generate a PCS.
