Abstract: A wireless transmit/receive unit (WTRU) may process logical channel data from a logical channel and determine that a type of trigger has occurred for the logical channel based on higher layer signaling. In response to the type of trigger, the WTRU may transmit a predetermined sequence over an uplink control channel in a transmission time interval (TTI).

Abstract: A method and apparatus for uplink transmission over a non-contentious shared feedback channel are disclosed, wherein the parameters of the uplink transmission are determined by the parameters of a downlink transmission. A new uplink channel, called a physical shared uplink feedback channel (PSUFCH) is used for uplink transmission such as feedback information in response to a downlink transmission on a fast shared data channel. The content of the feedback information may be general, e.g. an ACK/NACK or a channel quality indicator (CQI). The PSUFCH is transmitted using power ramping that terminates upon reception of a downlink ACK (DLACK) from a Node-B. No ambiguity resolution is required due to the non-contentious and deterministic mapping of the uplink channel resources.

Abstract: The present invention relates to a method for confirming the delivery of a data packet in a mesh network by sending an acknowledgement (ACK) to an ingress mesh point (IMP). A mesh network comprises a plurality of mesh points that are wirelessly linked together. A data packet sent by a station (STA) is received by an IMP. A MAC frame is generated for transmission of the data packet and the frame is forwarded to an egress mesh point (EMP) in order to provide a service by the mesh network. The MAC frame includes a field comprising an IMP address and an EMP address. When the EMP, (or optionally an intermediate mesh point), receives a data packet successfully, the EMP or the intermediate mesh point sends an ACK to the IMP or preceding mesh point.

Abstract: A method and apparatus for requesting and releasing resources for a wireless transmit/receive unit (WTRU) and/or Node B. The WTRU may transmit a channel acquisition request to the Node B and receive a resource allocation from the Node B. The resource allocation may include a common resource. The WTRU may release the common resource. The release may be based on one or more conditions. The channel acquisition request or the resource allocation may include information related to one or more channels or resources.

Abstract: The present invention discloses a method and system for efficiently supporting data calls to WTRUs in systems that also support telephony. Various types of data is transmitted on a known schedule which is tightly synchronized to a predetermined time frame. The WTRUs synchronize their wake-up periods to search for data at times when data may or will actually be transmitted to them.

Abstract: A method and system is disclosed for a device to quickly determine if data is being sent to it. If no data is being sent to the device, the device may return to a sleep mode so as to conserve energy. The present invention includes organizing and transmitting, one at a time, all device destination identifiers. If a message listing search indicates that no message is being sent for a device, the device can continue with any other activity that needs servicing, or if no other activity is pending, it may shut down to conserve power until the next wake up period arrives. If the search returns a positive indication, the count value when the identifier is found can be used to determine the location of the pointer to the message.

Abstract: A method and apparatus for transferring buffered enhanced uplink (EU) data is disclosed. The WTRU transmits an EU data transmission request message. The WTRU determines, based on the EU data scheduling message, whether granted resources allow for the amount of EU data stored in the buffer to be transmitted and transmits a portion of the EU data stored in the buffer along with an indication indicating whether the granted resources allow the amount of EU data stored in the buffer to be transmitted.

Abstract: A method and apparatus are described for controlling transmitter power in a wireless communication system in which both dedicated and shared channels are utilized. A wireless transmit/receive unit (WTRU) may receive a first channel (e.g., downlink shared channel), power commands for a second channel (e.g., dedicated channel) and power commands for a third channel (e.g., uplink shared channel). The WTRU may transmit in a transmission time interval at least one of the second channel and the third channel. Acknowledgments and negative acknowledgements to signals received over the first channel may be sent on the third channel. The WTRU may determine a transmission power level of the second channel in response to the second channel power commands and not the third channel power commands. The WTRU may determine a transmission power level of the third channel in response to the third channel power commands and not the second channel power commands.

Abstract: A method and wireless transmit/receive unit (WTRU) for enhanced uplink data transmission is disclosed. A transport block size for transmission of enhanced uplink data is selected. A medium access control (MAC) protocol data unit (PDU) is segmented into a plurality of segments on a condition that the MAC PDU does not fit in a transport block according to the selected transport block size. A transport block is produced having the transport block size and includes at least one of the plurality of segments. The transport block is transmitted over an enhanced uplink channel and an indication of the transport block size is transmitted over an associated physical control channel.
