Abstract: A method and apparatus for uplink transmission is disclosed. A WTRU transmits a first type message to a Node-B that indicates that the WTRU has uplink buffered data to transmit and the WTRU requires uplink resources for transmission of the uplink buffered data. The WTRU receives a first uplink data scheduling message in response to the transmitted first type message. Subsequent to receiving the first uplink data scheduling message, the WTRU transmits a second type message or a third type message. The second type message includes a plurality of indications. The third type message indicates an amount of uplink buffered data and has less information than the second type message. The WTRU receives, in response to the transmitted second type message or third type message, a second uplink data scheduling message and transmits uplink data over an uplink channel based on the received second uplink data scheduling message.

Abstract: A wireless transmit/receive unit (WTRU) is configured to receive at least one serving grant and at least one non-scheduled grant. The at least one serving grant is a grant for scheduled data transmission. The at least one non-scheduled grant is a grant for non-scheduled data transmission. The WTRU is configured to determine supported enhanced dedicated channel transport format combinations (E-TFCs) within a E-TFC set (E-TFCS) based on a remaining transmit power for enhanced uplink (EU) transmission. The WTRU is configured to limit medium access control for dedicated channel (MAC-d) flow data multiplexed into a medium access control for enhanced uplink (MAC-e) protocol data unit (PDU) to a largest E-TFC size that is smaller than a size of MAC-d flow data allowed by the received serving and non-scheduled grants and available for transmission.

Abstract: A user equipment (UE) may receive a first downlink signal, which may include a resource assignment having an indication of a first resource of a plurality of resources. The resource assignment may also have an indication of a number of resources of the plurality of resources. In addition, the plurality of resources may be consecutive resources in a sequence. Further, the first downlink signal may include an indication of a first time interval of a plurality of time intervals and a number of time intervals of the plurality of time intervals to which the resource assignment applies. Moreover, the plurality of time intervals may be consecutive time intervals. Additionally, the UE may receive at least one additional downlink signal over a downlink shared channel in the plurality of resources and in the plurality of time intervals. In an example, the first downlink signal may be received over a downlink signaling channel.

Abstract: In a wireless communication system comprising at least one evolved Node-B (eNB) and a plurality of wireless transmit/receive units (WTRUs), a non-contention based (NCB) channel is established, maintained, and utilized. The NCB channel is allocated for use by one or more WTRUs in the system for utilization in a variety of functions, and the allocation is communicated to the WTRUs. The wireless communication system analyzes the allocation of the NCB channel as required, and the NCB channel is reallocated as required.

Abstract: A method and apparatus for selecting multiple transport formats and transmitting multiple transport blocks (TBs) in a transmission time interval simultaneously with multiple hybrid automatic repeat request (H-ARQ) processes in a wireless communication system are disclosed. Available physical resources and H-ARQ processes associated with the available physical resources are identified and channel quality of each of the available physical resources is determined. Quality of service (QoS) requirements of higher layer data to be transmitted are determined. The higher layer data is mapped to at least two H-ARQ processes. Physical transmission and H-ARQ configurations to support QoS requirements of the higher layer data mapped to each H-ARQ process are determined. TBs are generated from the mapped higher layer data in accordance with the physical transmission and H-ARQ configurations of each H-ARQ process, respectively. The TBs are transmitted via the H-ARQ processes simultaneously.

Abstract: Service data is transferred in a wireless communication system. A first service identification is transmitted for reception by a group of users of a cell in the system. The group of users does not include all of the users of the cell. Each of the group of users receives the service identification. Each of the group of users monitors for a second service identification being transmitted over a high speed downlink shared channel (HS-DSCH). The service data is transmitted over the HS-DSCH with the second service identification. Each of the group of users detects the second service identification and receives the service data of the HS-DSCH.

Abstract: A Node-B sends a polling message to a wireless transmit/receive unit (WTRU). The WTRU sends an uplink synchronization burst in response to the polling message without contention. The Node-B estimates an uplink timing shift based on the synchronization burst and sends an uplink timing adjustment command to the WTRU. The WTRU then adjusts uplink timing based on the uplink timing adjustment command. Alternatively, the Node-B may send a scheduling message for uplink synchronization to the WTRU. The WTRU may send a synchronization burst based on the scheduling message. Alternatively, the WTRU may perform contention-based uplink synchronization after receiving a synchronization request from the Node-B. The WTRU may enter an idle state instead of performing a handover to a new cell when the WTRU moves to the new cell. A discontinuous reception (DRX) interval for the WTRU may be set based on activity of the WTRU.

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.
