    摘要: Since common E-DCH resources may be assigned from a single Node B, uplink macro-diversity may not be possible between neighboring Node B's. In addition, a user equipment (UE) assigned a common E-DCH resource may not be allowed to perform cell reselection. Thus, maintaining the assignment of a common E-DCH resource to a given UE for more than a few hundred milliseconds may result in unacceptable inter-cell interference, for example, when the UE moves closer to a neighboring cell controlled by a non-serving Node B. To overcome inter-cell interference and allow a more extensive utilization of the Cell_FACH state, a method may be used to detect and/or control inter-cell interference.

    摘要: A method for acquiring and applying offload area information for offloading a wireless transmit/receive unit (WTRU) to a small cell in a different frequency layer is disclosed. The WTRU may enter a region or a macro cell and receive offload area information of the region in which a small cell in the vicinity of the macro cell is located. The offload information may be received in a system information block (SIB), dedicated signaling, or any other radio signal. The WTRU may perform measurements to determine the location of the WTRU and to determine whether it has entered any offload areas. Upon a determination that the offload area information is no longer valid, the WTRU may delete the offload area information.

    摘要: Systems, methods, and instrumentalities are disclosed for a wireless transmit/receive unit (WTRU) to transmit uplink information. The WTRU may have information such as data or control information to transmit to a network. The (WTRU) may request a common enhanced dedicated channel (E-DCH) resource from the network. The WTRU may receive an indication from the network to fallback using a random access channel, e.g. a Release 99 Random Access Channel (R99 RACH), a Release 99 Physical Random Access Channel (R99 PRACH), etc. The indication may be received via an acquisition indicator (E-AI). The indication may be a value of the E-AI. The WTRU may determine whether a condition is met. The WTRU may transmit the uplink information over the R99 PRACH if the condition is met.

    摘要: A method and wireless transmit/receive unit (WTRU) for establishing multi-cell operation in a non-fully connected state are disclosed. The method may include the WTRU accessing a primary cell. The method may include the WTRU determining at least one potential secondary cell. The method may include the WTRU initiating access to the at least one potential secondary cell while simultaneously accessing the primary cell in a non-fully connected state. The non-fully connected state may correspond to the WTRU accessing the primary cell without dedicated radio resources being allocated to the WTRU.

    摘要: A method and apparatus are used to generate radio link control (RLC) protocol data units (PDUs). A data request for a logical channel is received as part of an enhanced dedicated channel (E-DCH) transport format combination (E-TFC) selection procedure in a medium access control (MAC). Upon determining the data field size, an RLC PDU is generated such that it matches the requested data from the E-TFC selection. The size of the RLC PDU generated can be greater than or equal to the minimum configured RLC PDU size (if data is available) and less than or equal to the maximum RLC PDU size. The data is then transmitted in the RLC PDU in a current transmission time interval (TTI).
