Abstract: A method and a wireless transmit/receive unit (WTRU) (600), including a universal subscriber identity module (USIM) (625), for identifying a closed subscriber group (CSG) cell are disclosed. The WTRU (600) receives a broadcast from a cell including a cell identifier (ID). If the cell ID is associated with a CSG cell, the WTRU (600) determines whether the CSG ID is programmed in the USIM (625). 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 of adaptive sequence numbering in a wireless communication system includes determining whether or not a packet to be transmitted will be segmented. Based upon the segmentation determination, a determination as to whether or not to include a radio link controller (RLC) specific automatic repeat request (ARQ) sequence number (SN) to the packet is made. An indicator is added to indicate whether or not the RLC-specific ARQ SN is included in the packet. The packet is transmitted, and an acknowledgment (ACK) is received for the transmitted packet.

Abstract: A method and system for eliminating interference caused by hidden nodes is disclosed. An initiator control message is defined for an initiator, (typically a wireless station (STA)), in order to begin an aggregate frame exchange with at least one responder. The initiator control message includes information on the queue sizes at the initiator. A responder, (typically an access point (AP)), sets up the required protection for the transmission of data by the initiator based on information on the queue sizes indicated in a field of the initiator control message using a responder control message. Other STAs that receive the responder control message set parameters for a wireless medium access accordingly. In another embodiment, multiple receiver aggregate multi-poll (MMP) and power save aggregation descriptor (PSAD) control frames are configured for transmission by a non-AP STA to provide enhanced scheduling and mitigate hidden node problems.

Abstract: The present invention is a method and apparatus for resource allocation signaling for grouping user real time services. Uplink signaling for voice activity reporting of each user's transition between an active state and an inactive voice state is sent from a wireless transmit/receive unit to a Node B. Radio resource allocation to users of a wireless communication system varies based on user measurement reporting, a pre-determined pattern such as frequency hopping, or a pseudorandom function. Grouping methods are adjusted to better utilize the voice activity factor, so that statistical multiplexing can be used to more efficiently utilize physical resources.

Abstract: Each of a plurality of packets in a particular flow is classified into one of a plurality of quality of service (QoS) classes based on information about each packet. Each packet is then adaptively processed based on the QoS class for each packet. The classification may be performed based on media information included in a session description protocol (SDP) messaging. The classification may also be performed based on a real-time transmit protocol (RTP) payload, an RTP header, a transmission control protocol (TCP) header, a user datagram protocol (UDP) header, and an Internet protocol (IP) header. The packets may be transmitted using multiple system architecture evolution (SAE) radio bearers each of which is used to deliver differentiated QoS requirements. The packets may be mapped to eigen-modes based on the QoS class of each packet such that a packet requiring a higher level of QoS is mapped to a stronger eigen-mode. Packets may be segmented into a plurality of segments where each segment is classified into one of the QoS classes based on information about each segment.

Abstract translation: 基于关于每个分组的信息将特定流中的多个分组中的每一个分类为多个服务质量（QoS）类别中的一个。 然后基于每个分组的QoS类自适应地处理每个分组。 可以基于包括在会话描述协议（SDP）消息中的媒体信息来执行分类。 分类也可以基于实时传输协议（RTP）有效载荷，RTP头，传输控制协议（TCP）报头，用户数据报协议（UDP）报头和因特网协议（IP）报头）来执行。 可以使用多个系统架构演进（SAE）无线电承载来发送分组，每个承载用于提供不同的QoS要求。 分组可以基于每个分组的QoS类被映射到本征模式，使得需要更高级别的QoS的分组被映射到更强的本征模式。 分组可以被分割成多个段，其中基于关于每个段的信息将每个段分类为QoS类别之一。

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竞争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来调整上行链路定时。 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。

Abstract: A method and system for supporting voice over Internet protocol (VoIP) services over a wireless communication network are disclosed. Data is encoded at a coding rate specified by a controller for generating a VoIP packet. Among the encoded data, bits sensitive to errors and bits not sensitive to errors are identified and error protection is performed separately by a medium access control layer and/or physical layer. A header of the VoIP packet may be selectively compressed in accordance with an indication from the controller. A user datagram protocol (UDP)-Lite may be used for partial coverage of the sensitive bits. A comfort noise may be generated by a receiving end during a silence period without receiving a comfort noise packet from a transmitting end. If the VoIP packet is not fit into a currently assigned radio resource, the VoIP packet may be fragmented.

Abstract translation: 公开了一种通过无线通信网络支持通过因特网协议语音（VoIP）服务的方法和系统。 数据以由用于生成VoIP分组的控制器指定的编码速率进行编码。 在编码数据中，识别对错误敏感的位和对错误不敏感的位，并且由介质访问控制层和/或物理层单独执行错误保护。 可以根据来自控制器的指示来选择性地压缩VoIP分组的报头。 用户数据报协议（UDP）-Lite可用于敏感位的部分覆盖。 在静音期间可能由接收端产生舒适噪声，而不从发送端接收到舒适噪声分组。 如果VoIP分组不适合当前分配的无线电资源，则VoIP分组可能被分段。

Abstract: The present invention is related to a method and apparatus for facilitating lossless handover in a wireless communication system comprising at least one wireless transmit/receive unit (WTRU), a source evolved Node B (eNB), a target eNB, and a mobility management entity/user plane entity (MME/UPE) where the WTRU is in wireless communication with the source eNB. The source eNB determines to handover the WTRU to the target eNB, requests status reports from the WTRU, and requests handover to the target eNB. The handover request includes context information relating to the WTRU which is sent to the target eNB. The target eNB configures resources for the WTRU and transmits a handover response signal to the source eNB. The source eNB commands the WTRU to perform a handover to the target eNB and forwards data to the target eNB. The WTRU performs the handover to the target eNB.
