Abstract
A method of decoding enhanced uplink absolute grant channel (E-AGCH) transmissions in a wireless transmit/receive unit (WTRU). E-AGCH data is received, the E-AGCH data including a cyclic redundancy check (CRC) part and a data part, the CRC part having been masked with a WTRU identity (ID). The CRC part and the data part are demultiplexed and the CRC part is demasked with a first WTRU ID. A first CRC is performed with the data part and the CRC part demasked with the first WTRU ID. The data part is decoded on a condition that the first CRC passes.
Claims15
A method of decoding enhanced uplink absolute grant channel (E-AGCH) transmissions in a wireless transmit/receive unit (WTRU), the method comprising:
- receiving E-AGCH data, the E-AGCH data including a cyclic redundancy check (CRC) part and a data part, the CRC part having been masked with a WTRU identity (ID);
- demultiplexing the CRC part and the data part;
- demasking the CRC part with a first WTRU ID;
- performing a first CRC with the data part and the CRC part demasked with the first WTRU ID;
- and
- decoding the data part on a condition that the first CRC passes.
A wireless transmit/receive unit (WTRU) for decoding enhanced uplink absolute grant channel (E-AGCH) transmissions, the WTRU comprising:
- a receiver configured to receive E-AGCH data, the E-AGCH data including a data part and a cyclic redundancy check (CRC) part, the CRC part having been masked with a WTRU identity (ID);
- a demultiplexer configured to demultiplex the data part and the CRC part;
- a demasking unit configured to demask the CRC part with a WTRU ID;
- a CRC unit configured to perform a CRC on the data part with the demasked CRC part;
- and
- a controller configured to send the data part for decoding on a condition that the CRC passes.
