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 for performing cell reselection first determines a current cell selection quality value. The cell selection quality value is compared to a predetermined threshold. Measurements of neighboring cells are taken if the cell selection quality value is less than or equal to the predetermined threshold. Measurements can be taken of intra-frequency cells, inter-frequency cells, and inter-radio access technology cells. If a neighboring cell is found that is better than the current cell based on the measurements, then the better neighbor cell is reselected to.

Abstract: A method and apparatus may be used for supporting multiple hybrid automatic repeat request (H-ARQ) processes per transmission time interval (TTI). A transmitter and a receiver may include a plurality of H-ARQ processes. Each H-ARQ process may transmit and receive one TB per TTI. The transmitter may generate a plurality of TBs and assign each TB to a H-ARQ process. The transmitter may send control information for each TB, which may include H-ARQ information associated TBs with the TBs. The transmitter may send the TBs using the associated H-ARQ processes simultaneously per TTI. After receiving the TBs, the receiver may send feedback for each of the H-ARQ processes and associated TBs indicating successful or unsuccessful receipt of each of the TBs to the transmitter. The feedback for multiple TBs may be combined for the simultaneously transmitted H-ARQ processes, (i.e., TBs).

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.

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: 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 translation: 节点B向无线发射/接收单元（WTRU）发送轮询消息。 WTRU响应于轮询消息而无争用地发送上行链路同步突发。 节点B基于同步脉冲串估计上行链路定时偏移，并向WTRU发送上行链路定时调整命令。 然后，WTRU基于上行链路定时调整命令调整上行链路定时。 或者，节点B可以向WTRU发送用于上行链路同步的调度消息。 WTRU可以基于调度消息发送同步突发。 或者，WTRU可以在从节点B接收到同步请求之后执行基于竞争的上行链路同步。 当WTRU移动到新小区时，WTRU可以进入空闲状态而不是执行到新小区的切换。 可以基于WTRU的活动来设置WTRU的不连续接收（DRX）间隔。
