US 8,572,451 B2 · Method and apparatus for indicating a temporary block flow to which a piggybacked ACK/NACK field is addressed

Abstract

A method and apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed are disclosed. A sequence may be generated from a temporary flow identity (TFI) to which the PAN field is addressed and masked with a PAN check sequence (PCS). A radio block including a PAN field and a masked PCS is transmitted. The PCS may be masked with one of TFIs which is selected in accordance with a rule pre-agreed. A secondary identifier may indicate a TBF to which the PAN field is addressed. A special value may be used to represent all TBFs assigned and a secondary identifier may indicate a TBF to which the PAN field is addressed. A special value on the PAN field may be used for control purposes for indicating an action affecting a group of receiving stations listening to the radio block.

Dependent claims

A method for use in a wireless transmit/receive unit (WTRU), the method comprising:

the WTRU generating a piggybacked acknowledgement/non-acknowledgement (PAN) field;
the WTRU generating a PAN check sequence (PCS) from the PAN field;
the WTRU masking the PCS with a temporary flow identity (TFI) value that consists of five bits, wherein, based on a pre-determined condition, the TFI value is not associated with an address and each of the five bits has a value of zero;
and
the WTRU transmitting data that includes the PAN field and the masked PCS.
