Abstract: A method and apparatus for controlling enhanced dedicated channel (E-DCH) transmissions are disclosed. A plurality of primary absolute grants are received, wherein the plurality of primary absolute grants are associated with a TTI. At least one relative grant is received for E-DCH transmission, wherein the at least one relative grant is associated with the TTI. At least one serving grant for E-DCH transmission is determined. A H-ARQ process is identified for use for the TTI. It is determined whether the identified H-ARQ process is available for scheduled data and whether scheduled data is allowed to be transmitted in the TTI based at least on the identified H-ARQ process. On a condition that the identified H-ARQ process is available for scheduled data and scheduled data is allowed to be transmitted in the TTI, scheduled data is allocated for transmission in the TTI.

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 system and method for providing variable security levels in a wireless communication network. The present invention optimizes the often conflicting demands of highly secure wireless communications and high speed wireless communications. According to a preferred embodiment of the present invention, various security sensors are scanned to determine the likely presence of an intruder within a predetermined trust zone. If an intruder is likely present, the security level is changed to the highest setting, and consequently a lower data rate, while the intruder is identified. If the identified intruder is in fact a trusted node, the security level is returned to a lower setting. If the identified intruder is not a trusted node, the security level is maintained at an elevated state while the intruder is within the trust zone.

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) and a Node-B. The WTRU transmits an enhanced dedicated channel (E-DCH) allocation request to the Node-B over an uplink (UL) EU channel. In one embodiment, if E-DCH allocation cannot be provided within a predetermined time period, the Node-B sends an acknowledgement message to the WTRU via a downlink (DL) EU signaling channel without sending E-DCH allocation information. The request is queued in the Node-B and the WTRU 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 or whether channel allocation information was unsuccessfully delivered via the DL EU signaling channel.

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: A wireless transmit/receive unit (WTRU) may generate, on a condition that a scheduling request and an acknowledgement/negative acknowledgement (ACK/NACK) or channel quality information (CQI) are to be transmitted, a message having the scheduling request and the ACK/NACK or the CQI. The message may be transmitted over a physical uplink control channel. The WTRU may determine whether scheduling request information, including buffer status, is to be transmitted. The scheduling request information may be transmitted as in-band information.

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.
