Abstract: A METHOD AND APPARATUS FOR SENDING A CHANNEL QUALITY INDICATION, CQI (206) VIA A SHARED CHANNEL WHILE A WIRELESS TRANSMIT/RECEIVE UNIT, WTRU (100) IS IN A CELL_FACH STATE WITHOUT HAVING A DEDICATED CHANNEL ALLOCATED FOR THE WTRU (100) ARE DISCLOSED. A WTRU (100) PERFORMS A MEASUREMENT OF AT LEAST ONE PARAMETER AND GENERATES A CQI (206) BASED ON THE MEASUREMENT. THE WTRU (100) THEN TRANSMITS THE CQI (206) VIA A RANDOM ACCESS CHANNEL, RACH. THE CQI (206) MAY BE TRANSMITTED USING AN RACH PREAMBLE. A PLURALITY OF SIGNATURE SEQUENCES MAY BE DIVIDED INTO A PLURALITY OF GROUPS. THE WTRU (100) MAY SELECT ONE GROUP BASED ON THE CQI (206) AND RANDOMLY SELECT A SIGNATURE SEQUENCE AMONG SIGNATURE SEQUENCES IN THE SELECTED GROUP FOR TRANSMITTING THE RACH PREAMBLE. THE CQI (206) MAY BE APPENDED TO THE RACH PREAMBLE. THE CQI (206) MAY BE TRANSMITTED VIA A CONTROL PART OR A DATA PART OF THE RACH MESSAGE. THE MOST ILLUSTRATIVE DRAWING:

Abstract: A method of high speed downlink packet access (HSDPA) link adaptation, comprises receiving at a Node B a channel quality measurement metric over a Measured Results on random access channel (RACH) information element (IE). The link is adapted based upon the received channel quality metric. In addition, a corresponding method at a WTRU is disclosed comprising performing a channel quality metric measurement and transmitting the channel quality metric measurement over a Measured Results on RACH IE to the Node B.

Abstract: A wireless transmit/receive units (WTRUs) receives a downlink transmission from a Node-B and decodes the downlink transmission. If the decoding is not successful, the WTRU sends a pre-defined burst signifying a negative acknowledgement (NACK) to the Node-B via a contention-based shared feedback channel. The pre-defined burst may be sent only once without requiring an acknowledgement. The Node-B calibrates a downlink transmit power so that the downlink transmission is transmitted to the WTRUs with a high likelihood. The Node-B may send a downlink transmission including multiple data streams processed using different modulation and coding schemes so that a WTRU having a high signal quality decodes all data streams while a WTRU having a low signal quality decodes less than all data streams. The Node-B sends a channel quality indicator (CQI) threshold so that each WTRU determines a data stream to report feedback based on the CQI threshold and a measured CQI.

Abstract: Paging in a HSDPA connected mode CELL_PCH or URA_PCH state. A WTRU is configured to select various PICH information that is broadcast by a base station (in the HSDPA associated PICH info" information element of a System Information block 5/5bis) by compiling a list of candidate PICHs, and selecting a PICH info based on the U-RNTI of the WTRU. The WTRU is configured to receive paging messages, based on the selected PICH information. In one embodiment, a preferred WTRU is configured to receive paging messages, based on a PICH, a HS-SCCH, and a HS-PDSCH. In another embodiment, a preferred WTRU is configured to receive paging messages, based on a PICH and a HS-PDSCH. In both embodiments, a time delay parameter (for timing the transmission of the PICH and the transmission of a paging message) is preferably used so that the WTRU may listen for either the HS-SCCH or HS-PDSCH for a period of time and return to a sleep mode if no paging message is received.

Abstract: A METHOD AND APPARATUS FOR GENERATING AND PROCESSING A HIGH SPEED DOWNLINK SHARED CHANNEL (HS-DSCH) MEDIUM ACCESS CONTROL (MAC-EHS) PROTOCOL DATA UNIT (PDU) ARE DISCLOSED. MAC-EHS SERVICE DATA UNITS (SDUS) ARE MULTIPLEXED BASED ON A LOGICAL CHANNEL IDENTITY. REORDERING PDUS ARE GENERATED FROM THE MULTIPLEXED MAC-EHS SDUS. A REORDERING PDU INCLUDES AT LEAST ONE MAC-EHS SDU AND/OR AT LEAST ONE MAC-EHS SDU SEGMENT. A MAC-EHS SDU IS SEGMENTED ON A PRIORITY CLASS BASIS IF A MAC-EHS SDU DOES NOT FIT INTO A REORDERING PDU. A MAC-EHS PDU IS GENERATED INCLUDING AT LEAST ONE REORDERING PDU. THE MAC-EHS SDUS MAY BE STORED IN PRIORITY QUEUES (516) BEFORE GENERATING THE REORDERING PDUS. ALTERNATIVELY, THE REORDERING PDUS MAY BE GENERATED FROM THE MULTIPLEXED MAC-EHS SDUS. ALTERNATIVELY, THE RECEIVED MAC-EHS SDUS MAY BE BUFFERED IN A CORRESPONDING BUFFER FOR EACH LOGICAL CHANNEL BEFORE MULTIPLEXED BASED ON A LOGICAL CHANNEL IDENTITY, OR REORDERING PDUS ARE GENERATED.

Abstract: A wireless transmit receive unit (WTRU) is configured to operate in an high speed data packet access (HSDPA) mode in a cell and/or state and to clear HSDPA resources when moving out of the cell and/or state. The WTRU is configured to clear HSDPA resources when conditions to perform high speed downlink shared channel reception are not met. When in cell transition or state transition, the WTRU checks whether there is an ongoing a high speed downlink scheduling channel (HS-DSCH) reception, and if the new cell or state cannot support HS-DSCH, then the HSDPA resources being used for the ongoing HS-DSCH reception are released. The WTRU uses radio resource control (RRC) processing, and monitors various events and conditions such as an RRC variable HS_DSCH_RECEPTION_GENERAL, which tracks HS-DSCH reception for all states in order to make the determination whether to release HSDPA resources.
