Abstract: A method performed by a WTRU may comprise receiving scheduling information on a broadcast control channel (BCCH) which defines time periods for reception of broadcast messages transmitted on a downlink shared channel. The WTRU may determine whether additional messages are available upon request. The availability of the additional messages is indicated via the BCCH. The WTRU may transmit a request for one or more of the additional messages.

Abstract: 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.

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: Methods and apparatus are described for providing compatible mapping for backhaul control channels, frequency first mapping of control channel elements (CCEs) to avoid relay-physical control format indicator channel (R-PCFICH) and a tree based relay resource allocation to minimize the resource allocation map bits. Methods and apparatus (e.g., relay node (RN)/evolved Node-B (eNB)) for mapping of the Un downlink (DL) control signals, Un DL positive acknowledgement (ACK)/negative acknowledgement (NACK), and/or relay-physical downlink control channel (R-PDCCH) (or similar) in the eNB to RN (Un interface) DL direction are described. This includes time/frequency mapping of above-mentioned control signals into resource blocks (RBs) of multimedia broadcast multicast services (MBMS) single frequency network (MBSFN)-reserved sub-frames in the RN cell and encoding procedures for these. Also described are methods and apparatus for optimizing signaling overheads by avoiding R-PCFICH and minimizing bits needs for resource allocation.

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 method and apparatus for receiving an IP-based message, by a first UE over a WLAN, is provided. The method may comprise transmitting at least one IP-based registration message and transmitting capability information including at least a terminal type of the first UE. The first UE may receive from a second UE, the IP-based message formatted according to the capability information. The first UE may be addressed using a first MSISDN. In one embodiment, the capability information indicates a memory size of the first UE. In one embodiment, the capability information indicates support for the first UE to receive an animation.

Abstract: A method and apparatus may be used in wireless communications. The apparatus may be an access point (AP), and may transmit a power save frame. The power save frame may include one or more Uplink (UL) Transmission Times (ULT)s. The apparatus may determine that a station (STA) did not transmit during its respective ULT. The AP may transmit another power save frame. The other power save frame may include a modified ULT. The modified ULT may be for a STA that did not transmit during its respective ULT. The other power save frame may include an unmodified ULT. The unmodified ULT may be for a STA that did not transmit.

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.
