摘要： A method and apparatus for providing wireless communication services, (e.g., multimedia broadcast multicast services (MBMS)), are disclosed. A wireless transmit/receive unit (WTRU) detects a plurality of target cell evolved Node-Bs (eNodeBs) that neighbor a serving cell eNodeB. The WTRU evaluates cell reselection criteria and determines a neighboring target cell eNodeB to reselect. The WTRU receives and reads master information block (MIB) and system information messages of the neighboring target cell eNodeB, and confirms that the determined neighboring target cell eNodeB is not part of a multimedia broadcast single frequency network (MBSFN). The WTRU identifies the neighboring target cell eNodeB to the serving cell eNodeB. The WTRU then receives and reads MIB messages of the neighboring target cell eNodeB again to determine whether the system information has changed and, if so, the WTRU reads the system information and reselects to the neighboring target cell eNodeB, which provides the wireless communication services.

摘要： A method and apparatus are disclosed for prioritizing logical channels when a new transmission is performed. Logical channel resources are allocated for available data to a plurality of logical channels. A maximum bit rate (MBR) credit (i.e., token) is decremented in a buffer (i.e., bucket) associated with a particular one of the logical channels by the size of a medium access control (MAC) service data unit (SDU). The MBR credit may have a negative value. If any of the allocated channel resources remain, the logical channels are served n a decreasing priority order until the data is exhausted. A radio link control (RLC) SDU is not segmented if the whole RLC SDU fits into the remaining resources. The MAC SDU excludes a MAC PDU header and MAC padding.

摘要： A method and a wireless transmit/receive unit (WTRU), including a universal subscriber identity module (USIM), for identifying a closed subscriber group (CSG) cell are disclosed. The WTRU receives a broadcast from a cell including a cell identifier (ID). If the cell ID is associated with a CSG cell, the WTRU determines whether the CSG ID is programmed in the USIM. The cell broadcast may include a single bit information element (IE) indicating that the cell is a CSG cell. If the cell ID is a CSG ID, the cell ID may further include a plurality of fields which indicate at least one of a country, a region, an operator, and a home evolved Node-B (HeNB) number. The cell broadcast may further include a bit indicating whether the CSG cell is public or private. The cell broadcast may further include a bit indicating that emergency calls are allowed from all users.

摘要： A method for performing a manual cell search by a wireless transmit/receive unit (WTRU) includes receiving a manual cell search command and searching for home enhanced Node B (HeNB) cells during a time period. The time period may be a measurement gap or a discontinuous reception period. If an existing measurement gap is available for the WTRU to use, the search can be performed during that gap. Otherwise, the WTRU can request a new measurement gap to search for HeNBs.

摘要： A method and system for performing handover in a third generation (3G) long term evolution (LTE) system are disclosed. A source evolved Node-B (eNode-B) makes a handover decision based on measurements and sends a handover request to a target eNode-B. The target eNode-B sends a handover response to the source eNode-B indicating that a handover should commence. The source eNode-B then sends a handover command to a wireless transmit/receive unit (WTRU). The handover command includes at least one of reconfiguration information, information regarding timing adjustment, relative timing difference between the source eNode-B and the target eNode-B, information regarding an initial scheduling procedure at the target eNode-B, and measurement information for the target eNode-B. The WTRU then accesses the target eNode-B and exchanges layer 1/2 signaling to perform downlink synchronization, timing adjustment, and uplink and downlink resource assignment based on information included in the handover command.
