摘要： A method and apparatus for indicating a transmission status to a higher layer are disclosed. In the transmitting entity, a radio link control (RLC) entity sends a packet delivery notification regarding delivery status of a higher layer message to a higher layer entity based on hybrid automatic repeat request (HARQ) feedback information obtained from an HARQ entity. The RLC entity may send the packet delivery notification to the higher layer entity based on an RLC status report. Alternatively, the HARQ entity may send the packet delivery notification to the higher layer entity and/or the RLC entity based on HARQ feedback. The higher layer entity may update the higher layer message before retransmitting the higher layer message. If the RLC entity segments an RLC service data unit (SDU) and delivery of at least one segment of the RLC SDU fails, the RLC entity may discard the RLC SDU.

摘要： A method and apparatus for transport format combination restriction in a high speed downlink packet access (HSDPA) system. An enhanced transport format combination (E-TFC) table is split into sub-tables. A wireless transmit/receive unit (WTRU) selects one of the sub-tables and a window within the selected sub-table to search. The WTRU then determines whether or not a first element in the search window is blocked. If the first element in the search window is blocked, then the WTRU assumes that all of the elements in the selected sub-table are blocked. If the first element in the search window is not blocked, the WTRU then determines whether a last element in the search window is blocked. If the last element is not blocked, the WTRU assumes that all elements smaller than or equal to the last element are not blocked, and all elements greater than the last element are blocked. If the last element is blocked, the size of the search window is reduced until it is determined that the last element is not blocked.
摘要翻译：在高速下行链路分组接入（HSDPA）系统中用于传输格式组合限制的方法和设备。增强的传输格式组合（E-TFC）表被分成子表。无线发射/接收单元（WTRU）选择子表中的一个和所选子表内的窗口进行搜索。 WTRU然后确定搜索窗口中的第一个元素是否被阻塞。如果搜索窗口中的第一个元素被阻塞，则WTRU假定所选子表中的所有元素都被阻塞。如果搜索窗口中的第一个元素未被阻塞，则WTRU随后确定搜索窗口中的最后一个元素是否被阻塞。如果最后一个元素未被阻塞，则WTRU假定小于或等于最后一个元素的所有元素都不被阻塞，并且大于最后一个元素的所有元素都被阻塞。如果最后一个元素被阻止，搜索窗口的大小会减小，直到确定最后一个元素未被阻止为止。

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）传输的方法和设备。如果分组未被成功发送，则确定是否满足HARQ提前终止条件。如果满足HARQ提前终止条件，则HARQ过程终止并且在HARQ等级丢弃该分组。如果尚未接收到肯定确认（ACK），直到重传次数达到基于信道条件，测量等动态配置的预定限制，则满足HARQ提前终止条件。或者，如果满足HARQ提前终止条件成功传输分组所需的传输功率远高于实际传输功率。或者，如果选择用于重传的传输格式组合（TFC）不同于最佳TFC，则满足HARQ提前终止条件。可以通知较高层HARQ早期终止。

摘要： Techniques for component carrier-specific reconfiguration are disclosed. A wireless transmit/receive unit (WTRU) is capable of transmitting or receiving via multiple component carriers. The WTRU may perform component carrier reconfiguration on a component carrier basis to add, remove or replace a component carrier. Discontinuous reception (DRX) and/or discontinuous transmission (DTX) may be performed on at least one component carrier, wherein DRX and/or DTX patterns on the component carriers may not overlap each other. A random access procedure may be performed at the target cell on one component carrier while other component carriers are inactive. The component carrier-specific reconfiguration or handover of a component carrier or a channel may be implemented in coordinated multiple point transmission (CoMP), wherein a handover of a control channel, not a traffic channel, may be performed. Alternatively, a handover of a traffic channel may be performed.
