    摘要： 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.

    摘要： A method and apparatus for implementing a security procedure during handover of a wireless transmit/receive unit (WTRU) in wireless communications that controls the behavior of a handover target if it cannot support the required security algorithms. The handover source can detect that the target does not support the required security algorithms and the WTRU can detect that security algorithms may change during handover. Security procedures for the WTRU include contingencies for Radio Link Failure and if the public land mobile network (PLMN) changes.

    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.
