    Abstract: Se divulga un método para responder a la presencia de un campo de confirmacion/confirmacion negativa soportada (PAN) en el informe de una calidad de senal recibida para una unidad inalámbrica de transmision/recepcion (WTRU) corriente. Se hace una determinacion respecto de si un bloque de radio recibido está destinado a la WTRU corriente. Se mide la calidad de senal recibida del bloque de radio si el bloque de radio está destinado a la WTRU corriente. Se incluyen bits del campo de PAN en la determinacion de la calidad de senal recibida del bloque de radio sobre la base de una opcion preconfigurada. Se incluye la medicion de bloque de radio en un informe de medicion si una cabecera de datos del bloque de radio no está dirigida a la WTRU corriente pero el campo de PAN está dirigido a la WTRU corriente.

    Abstract: A method and an apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addre ssed. A method and apparatus of performing receive processing to reduce the probability of false acceptance of erroneous PANs are also disclosed. A tran smit station generates a PAN check sequence (PCS) and performs a channel cod ing on a PAN field and the PCS. The transmit station scrambles the encoded b its of the PAN field and the PCS with a TBF-specific scrambling code. Becaus e 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 decodin g will fail if received by a non-intended receive station. Alternatively, th e scrambling may be performed before the channel coding. Alternatively, the transmit station may combine the PAN field and a temporary flow identity (TF I) to generate a PCS.

    Abstract: Methods and base stations are described. A base station includes a receiver, a processor and a transmitter. The receiver receives a first data block associated with an uplink temporary block flow (TBF), and the first data block includes a first header that includes a temporary flow identity (TFI) that identifies the uplink TBF. The processor generate a piggybacked acknowledgement/non-acknowledgement (PAN) field corresponding to the uplink TBF and a PAN check sequence (PCS) based on the PAN field, masks a subset of PCS bits with the TFI to generate a masked PCS, and generates a second data block, associated with a downlink TBF, that includes a second header, a data part corresponding to the downlink TBF, the PAN field, and the masked PCS. The transmitter transmits the second data block.
