Abstract: A method and apparatus are provided for dynamic resource allocation, scheduling and signaling for variable data real time services (RTS) in long term evolution (LTE) systems. Preferably, changes in data rate for uplink RTS traffic are reported to an evolved Node B (eNB) by a UE using layer 1, 2 or 3 signaling. The eNB dynamically allocates physical resources in response to a change in data rate by adding or removing radio blocks currently assigned to the data flow, and the eNB signals the new resource assignment to the UE. In an alternate embodiment, tables stored at the eNB and the UE describe mappings of RTS data rates to physical resources under certain channel conditions, such that the UE uses the table to locally assign physical resources according to changes in UL data rates. Additionally, a method and apparatus for high level configuration of RTS data flows is also presented.

Abstract: 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.

Abstract: Methods and wireless devices are described. A method includes a wireless device transmitting to wireless transmit/receive units (WTRUs) by being scheduled by the base station or using a pool of radio resources, which is for any of a plurality of wireless devices to use for transmission to WTRUs. On a condition that the wireless device is to be scheduled by the base station, the wireless device receives scheduling information for transmission to a WTRU having a group radio network terminal identifier (RNTI) and transmits to the WTRU in response to the received scheduling information. The scheduling information for transmission to the base station uses a different RNTI. On a condition that the wireless device is to use the pool of radio resources for transmission to a WTRU, the wireless device transmits to the WTRU without being scheduled by the base station using the pool of radio resources.

Abstract: A method for multi-band operation by a first transmit/receive unit (TRU) is disclosed. The method may comprise monitoring a plurality of frequency bands including a first band and a second band. A first beacon may be received on the first band and a determination may be made, based on the received first beacon, of a first beacon period start time. The first beacon period start time may correspond to beacons transmitted by the second TRU. A second beacon period start time may be determined, based on the received first beacon, wherein the second beacon period start time corresponds to a beacon for transmission by the first TRU. A beacon signal may be transmitted in a second band, by the first TRU, wherein the beacon signal is timing aligned with beacon signals of the second TRU. The first band and the second band may be adjacent radio bands.

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: 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 a wireless transmit/receive unit (WTRU), including a universal subscriber identity module (USIM), for identifying a closed subscriber group (CSG) cell are disclosed. The WTRU receives a broadcast from a cell including a cell identifier (ID). If the cell ID is associated with a CSG cell, the WTRU determines whether the CSG ID is programmed in the USIM. The cell broadcast may include a single bit information element (IE) indicating that the cell is a CSG cell. If the cell ID is a CSG ID, the cell ID may further include a plurality of fields which indicate at least one of a country, a region, an operator, and a home evolved Node-B (HeNB) number. The cell broadcast may further include a bit indicating whether the CSG cell is public or private. The cell broadcast may further include a bit indicating that emergency calls are allowed from all users.
