摘要： A method of cell reselection in a wireless communications system where parameters are transmitted by the network in system information blocks to WTRU's on the network. Parameters are either added or subtracted from an equation representing the signal power and/or quality of a cell. Parameters may be prioritized. The results of the calculations are used to rank the servicing cell and neighboring cells. If a neighboring cell has a higher quality than the servicing cell, then the WTRU reselects the better cell. The network may transmit a blacklist of cells where the WTRU cannot camp as well as a barring timer for each cell where if the timer expires, the cell may again be considered for reselection. Information germane to the reselection decision may be transmitted and used by the network.
摘要翻译：一种在无线通信系统中小区重选的方法，其中参数由系统信息块中的网络传输到网络上的WTRU。从表示信号功率和/或单元质量的等式中加入或减去参数。可以优先考虑参数。计算结果用于对服务小区和相邻小区进行排序。如果相邻小区具有比服务小区更高的质量，则WTRU重新选择更好的小区。网络可以传输WTRU无法驻留的小区的黑名单以及每个小区的限制定时器，其中如果定时器到期，则该小区可以再次被考虑用于重选。与重选决定密切相关的信息可能被网络传输和使用。

摘要： A method and apparatus for providing and utilizing radio link control (RLC) and medium access control (MAC) packet delivery notification are disclosed. A MAC entity tracks a delivery status of a MAC protocol data unit (PDU) and sends MAC service data unit (SDU) delivery notification to an RLC entity and/or an upper layer upon occurrence of a triggering event. The triggering event may be expiration of a timer, a packet discard decision, MAC reset, MAC re-establishment, or a request from the upper layer. The RLC entity may also track a delivery status of an RLC service data unit (SDU) and send RLC delivery notification to the upper layer. An upper layer including a header compression entity may adjust a header compression parameter based on the RLC delivery notification or the MAC delivery notification. The RLC delivery notification may be used for lossless handover. Retransmission may be performed at the upper layer based on the RLC delivery notification or the MAC delivery notification.

摘要： A method and apparatus for hybrid automatic repeat request (HARQ) transmission are disclosed. If a packet has not been successfully transmitted, it is determined whether an HARQ early termination condition is met. If the HARQ early termination condition is met, the HARQ process is terminated and the packet is discarded at the HARQ level. The HARQ early termination condition is met if a positive acknowledgement (ACK) has not been received until the number of retransmissions reaches a predetermined limit that is dynamically configured based on channel condition, measurement, etc. Alternatively, the HARQ early termination condition is met if a transmit power required for successful transmission of the packet is much higher than an actual transmit power. Alternatively, the HARQ early termination condition is met if a transport format combination (TFC) selected for retransmission is different from an optimal TFC. A higher layer may be notified of the early HARQ termination.
摘要翻译：公开了一种用于混合自动重传请求（HARQ）传输的方法和装置。如果分组尚未成功发送，则确定是否满足HARQ提前终止条件。如果HARQ提前终止条件被满足，则HARQ过程被终止，并且在HARQ级别丢弃该分组。如果在重发次数达到基于信道条件，测量等动态配置的预定限制之前尚未接收到肯定确认（ACK），则HARQ提前终止条件得到满足。或者，如果符合HARQ提前终止条件成功发送分组所需的发射功率远高于实际的发射功率。或者，如果选择用于重传的传输格式组合（TFC）不同于最优TFC，则满足HARQ提前终止条件。可以向较高层通知早期HARQ终止。

摘要： PROBLEM TO BE SOLVED: To perform a Circuit Switched (CS) fallback in wireless communications. SOLUTION: A Non-Access Stratum (NAS) of the apparatus determines whether to perform a CS fallback based on an Internet Protocol Multimedia Subsystem (IMS) registration status, and sends a service request indicating a request to perform the CS fallback when the WTRU is attached to a CS domain. The apparatus also includes an Access Stratum (AS) that receives the CS service request from the NAS, sends an indication of the CS service request in a Radio Resource Control (RRC) message to an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN), wherein the RRC message includes CS service information, and receives a handover command in response to the CS service request.
