Abstract: A METHOD AND APPARATUS FOR MINIMIZING REDUNDANT ENHANCED UPLINK, EU ALLOCATION REQUESTS AND FAULT-ISOLATING EU TRANSMISSION FAILURES THAT OCCUR BETWEEN A WIRELESS TRANSMIT/RECEIVE UNIT, WTRU (102) AND A NODE-B (104). THE WTRU (102) TRANSMITS AN ENHANCED DEDICATED CHANNEL, E-DCH ALLOCATION REQUEST TO THE NODE-B (104) OVER AN UPLINK, UL EU CHANNEL (110). IN ONE EMBODIMENT, IF EDCH ALLOCATION CANNOT BE PROVIDED WITHIN A PREDETERMINED TIME PERIOD, THE NODE-B (104) SENDS AN ACKNOWLEDGEMENT MESSAGE TO THE WTRU (102) VIA A DOWNLINK, DL EU SIGNALING CHANNEL WITHOUT SENDING E-DCH ALLOCATION INFORMATION. THE REQUEST IS QUEUED IN THE NODE-B (104) AND THE WTRU (102) REFRAINS FROM TRANSMITTING THE SAME REQUEST UNTIL AFTER THE TIME PERIOD EXPIRES OR RESOURCES BECOME AVAILABLE. IN ANOTHER EMBODIMENT, APPROPRIATE ACTIONS ARE TAKEN TO CORRECT EU TRANSMISSION FAILURES BY DETERMINING WHETHER AN E-DCH ALLOCATION REQUEST WAS UNSUCCESSFULLY DELIVERED VIA THE UL EU CHANNEL (110) OR WHETHER CHANNEL ALLOCATION INFORMATION WAS UNSUCCESSFULLY DELIVERED VIA THE DL EU SIGNALING CHANNEL. THE MOST ILLUSTRATIVE DRAWING IS

Abstract: A method and apparatus for accessing a contention-based uplink random access channel (RACH) in a single carrier frequency division multiple access (SC-FDMA) system are disclosed. A wireless transmit/receive unit (WTRU) randomly selects a RACH subchannel and a signature among a plurality of available RACH subchannels and signatures. The WTRU transmits a preamble using the selected signature via the selected RACH subchannel at a predetermined or computed transmission power. A base station monitors the RACH to detect the preamble and sends an acquisition indicator (AI) to the WTRU when a signature is detected on the RACH. When receiving a positive acknowledgement, the WTRU sends a message part to the base station. If receiving a negative acknowledgement or no response, the WTRU retransmits the preamble.

Abstract: A METHOD AND APPARATUS FOR IMPLEMENTING HYBRID AUTOMATIC REPEAT REQUEST (H-ARQ) IN A MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) WIRELESS COMMUNICATION SYSTEM ARE DISCLOSED. A TRANSMITTER (100) TRANSMITS AT LEAST TWO DATE PACKETS VIA TWO OR MORE ANTENNAS (102). IF AT LEAST ONE OF THE DATA PACKETS IS NOT SUCCESSFULLY TRANSMITTED, THE TRANSMITTER RETRANSMITS THE DATA PACKETS WHILE ARRANGING THE DATA PACKETS IN AN ORTHOGONAL SPREADING MANNER. ALTERNATIVELY, THE TRANSMITTER (100) MAY RETRANSMIT ONLY THE UNSUCCESSFULLY TRANSMITTED DATA PACKET ALONG WITH A NEW DATA PACKET, WHICH REPLACES A SUCCESSFULLY TRANSMITTED DATA PACKET. THE UNSUCCESSFULLY TRANSMITTED DATA PACKET MAY SIMPLY BE REPEATED WITHOUT CHANGING ITS FORMAT. WHEN ONLY THE UNSUCCESSFULLY TRANSMITTED DATA PACKET IS RETRANSMITTED ALONG WITH THE NEW DATA PACKET, THE TRANSMISSIONS MAY BE COMBINED TO RECOVER THE RETRANSMITTED DATA PACKET AND THE NEW DATA PACKET SIMULTANEOUSLY.

Abstract: In a wireless communication system including a wireless transmit/receive unit (WTRU) and at least one Node-B, a method and apparatus is used to selectively enable reception of at least one downlink (DL) enhanced uplink (EU) signaling channel established between the WTRU and the Node-B(s). During the operation of an enhanced dedicated channel (E-DCH), the WTRU monitors at least one DL EU signaling channel established between the WTRU and the Node-B(s) only when it is necessary, based on the WTRU's knowledge of at least one established standard procedure. The WTRU coordinates and consolidates DL signaling channel reception requirements of a plurality of channel allocation and/or data transmission procedures carried out by the WTRU in accordance with the established standard procedure. The WTRU determines whether to enable reception of at least one specific DL signaling channel based on the consolidated DL signaling channel reception requirements.
