摘要: 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.

摘要: 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.

摘要: Methods and apparatus are described. A wireless transmit/receive unit (WTRU) includes a transceiver and a processor operatively coupled to the transceiver. The transceiver and the processor establish a connection with a first wireless network node and a second wireless network node. The transceiver and the processor also receive power configurations and timing advances from the first wireless network node independently of the second wireless network node. The transceiver and the processor also simultaneously receive downlink signals from both the first wireless network node and the second wireless network node. The downlink signals are independently scheduled by a scheduler of the first wireless network node and a scheduler of the second wireless network node.

摘要: A first allocation of physical resources for uplink transmission is received over a downlink signaling channel. Data of a logical channel is received. A first block is transmitted over the first allocated physical resources in response to receipt of the data of the logical channel. A timer is initiated in response to transmission of the first block. In response to an expiration of the timer and not receiving a second allocation of physical resources, a first type of request from a plurality of types of requests is selected and the selected first type of request for the second allocation of physical resources is transmitted over an uplink signaling channel. The second allocation of physical resources is received in response to the transmitted first type of request. A second block is transmitted in response to the second allocation of physical resources over the second allocated physical resources.

摘要: 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.

摘要: A method and wireless transmit/receive unit (WTRU) for uplink transmission are disclosed. A WTRU receives configuration information. The configuration information includes logical channel priority information and a maximum number of hybrid automatic repeat request (HARQ) transmissions. For a transmission time interval (TTI), the WTRU identifies a HARQ process to use for uplink transmission for the TTI on a condition that an uplink grant is for the TTI. The WTRU selects data for uplink transmission for the TTI. For a new uplink transmission, data is allocated in decreasing order of priority based on the logical channel priority information. The WTRU initializes a transmission counter. The transmission counter indicates a number of transmissions associated with the selected data. The WTRU transmits the selected data over an uplink channel based on the uplink grant using the identified HARQ process.

摘要: A method and wireless transmit/receive unit (WTRU) that does not have an allocation of enhanced dedicated channel (E-DCH) resources is disclosed. The WTRU transmits E-DCH channel allocation information to a Node-B. In response to transmitting the E-DCH channel allocation information, the WTRU activates a timer. On a condition that an acknowledgement to the transmitted E-DCH channel allocation information is not received, the WTRU retransmits the E-DCH channel allocation information. On a condition that an acknowledgement to the transmitted E-DCH channel allocation information is received, the WTRU waits to transmit the E-DCH channel allocation information or updated E-DCH channel allocation information until the timer expires.
