摘要:
Methods, apparatus, and systems using almost blank subframes patterns are disclosed. Different ABS patterns and triggers are described for enabling a wireless transmit/receive unit (WTRU) to obtain ABS patterns. One representative method of scheduling operations by a wireless transmit/receive unit (WTRU) may include the WTRU receiving information indicating the ABS pattern with a plurality of ABS intervals of an interfering cell; determining timing associated with the ABS intervals of the interfering cell in accordance with the indicated ABS pattern; and scheduling a measurement opportunity, a transmission opportunity or a reception opportunity during the ABS intervals of the interfering cell.

Disclosed herein are systems and methods for managing home nodeB (HNB) mobility in forward access channel (Cell_FACH) states. According to an aspect, a method may be implemented at a Wireless Transmit/Receive Unit (WTRU). The method may include determining whether to communicate an indication to a network node for extended measurement occasion. Further, the method may include communicating the indication to the network node in response to determining to communicate the indication.

Embodiments contemplate methods and systems for determining and communicating channel state information (CSI) for one or more transmission points (or CSI reference signal resources). Embodiments further contemplate determining transmission states may include applying at least one transmission state parameter to channel state information (CSI). Embodiments also contemplate reporting CSI based on the transmission state and/or at least one transmission state parameter applied thereto.

A method and apparatus are provided that allow a wireless transmit/receive unit (WTRU) to search and add one or more closed subscriber group (CSG) identities (IDs) in the WTRU white list while in connected mode. Such method and apparatus include but are not limited to WTRU autonomous search or a manual search, WTRU initiated procedures, or network initiated procedures. Additionally, methods that allow the network and/or the non-access stratum (NAS) to add CSG IDs are also described.

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.

A method and apparatus for home Node-B (HNB) mobility with a local IP access (LIPA) packet data network (PDN) connection are described. A target home node-B (HNB) may receive a handover request message from a source HNB to handover a wireless transmit/receive unit (WTRU). A path switch request may be transmitted to a local gateway (LGW) to change a downlink data path towards the target HNB in response to the handover request message. The LGW may act as a mobility management and local mobility anchor for the handover; and informing an HNB gateway (GW) about the handover so that the downlink data path for core network (CN) traffic is modified towards the target HNB.
