    摘要: Techniques for performing a handover in a network with a relay node (RN) are disclosed. The RN is a node deployed between an eNodeB (eNB) and a wireless transmit/receive unit (WTRU). The RN receives data from one of the eNB and the WTRU and forwards it to the other. The RN receives a packet data convergence protocol (PDCP) protocol data unit (PDU) from a serving donor evolved Node-B (DeNB) and transmits it to the WTRU. The RN makes a handover decision based on the measurement report received from the WTRU. After making a handover decision, the RN sends a handover request or a control message to the serving DeNB including a first unsuccessfully transmitted PDCP sequence number (SN). The serving DeNB then discards a PDCP PDU with an SN older than the first unsuccessfully transmitted PDCP SN.

    摘要: In a wireless communication system using a reference channel used for error rate measurement and associated with a plurality of transport channels multiplexed on a coded composite transport channel (CCTrCH), a method is employed for reselection of the reference channel from favorable candidate transport channels. A channel is initially selected from the plurality of multiplexed channels as the reference channel. Channels are monitored based on quantitative data content criteria to determine whether an ON or OFF state exists. A different channel is selected from the plurality of multiplexed channels as the reselected RTrCH when a better candidate transport channel in the ON state becomes available, or when the monitored RTrCH reflects an OFF state.

    摘要: Methods and apparatus are described for supporting wireless transmit/receive unit (WTRU) mobility between Home (evolved) Node Bs (H(e)NBs) that are configured to communicate with a Local Gateway (L-GW). The H(e)NBs and/or L-GW may belong to one or more Local H(e)NB Networks (LHNs). A WTRU may receive services including Selected Internet Protocol (IP) Traffic Offload (SIPTO) or Local IP Access (LIPA) services from the L-GW via one or more H(e)NBs. The WTRU may continue to receive SIPTO or LIPA services after a handover to another H(e)NB that may be in communication with the same L-GW and may belong to the same LHN. The WTRU may receive information related to the LHN or the L-GW to allow continuation of SIPTO or LIPA services as the WTRU moves among H(e)NBs and/or out of the LHN. The WTRU may receive and/or maintain one or more LHN Lists.

    摘要: A method and apparatus for avoiding a collision. A collision may be avoided by allocating a first set of subframes to a backhaul link transmission, and allocating a second set of subframes to an access link transmission. In one example, the second set of subframes may be a non-overlapping set of subframes with respect to the first set of subframes. In a second embodiment, a collision may be avoided by receiving a data transmission from an evolved Node-B (eNB) and transmitting an uplink (UL) grant to a wireless transmit/receive unit (WTRU) and a first acknowledgement (ACK) to the eNB. The transmission may be in response to the received data transmission. The RN may avoid a collision by further transmitting an automatic ACK to the WTRU and transmitting a second UL grant to the WTRU. In a third embodiment, a collision between an access link transmission and a backhaul link transmission may be avoided by detecting a collision and determining an interface priority based on a collision occurrence type.
