摘要： A method of cell reselection in a wireless communications system where parameters are transmitted by the network in system information blocks to WTRU's on the network. Parameters are either added or subtracted from an equation representing the signal power and/or quality of a cell. Parameters may be prioritized. The results of the calculations are used to rank the servicing cell and neighboring cells. If a neighboring cell has a higher quality than the servicing cell, then the WTRU reselects the better cell. The network may transmit a blacklist of cells where the WTRU cannot camp as well as a barring timer for each cell where if the timer expires, the cell may again be considered for reselection. Information germane to the reselection decision may be transmitted and used by the network.

摘要： Various methods for adjusting a reselection timer and cell ranking criteria are disclosed. The ranking criteria of a serving or neighbor cell, or a reselection timer in a wireless transmit/receive unit (WTRU), is adjusted based on how a serving cell signal measurement, (e.g., signal strength, signal quality), compares to a plurality of thresholds over a time interval. In another method, cell ranking criteria is adjusted based on a hysteresis value and a scaling factor when a maximum number of reselections is exceeded and a high mobility factor is detected. Furthermore, a method of reporting cell signal measurements is disclosed, whereby a time-to-trigger time (TTT) interval is started when the neighbor cell signal measurement rises above a reporting range threshold. If the serving cell signal measurement falls below a serving cell threshold, the TTT interval is adjusted and thereby a measurement report is transmitted during the TTT interval.

摘要： A method and apparatus for indicating a transmission status to a higher layer are disclosed. In the transmitting entity, a radio link control (RLC) entity sends a packet delivery notification regarding delivery status of a higher layer message to a higher layer entity based on hybrid automatic repeat request (HARQ) feedback information obtained from an HARQ entity. The RLC entity may send the packet delivery notification to the higher layer entity based on an RLC status report. Alternatively, the HARQ entity may send the packet delivery notification to the higher layer entity and/or the RLC entity based on HARQ feedback. The higher layer entity may update the higher layer message before retransmitting the higher layer message. If the RLC entity segments an RLC service data unit (SDU) and delivery of at least one segment of the RLC SDU fails, the RLC entity may discard the RLC SDU.

摘要： A method and apparatus for transport format combination restriction in a high speed downlink packet access (HSDPA) system. An enhanced transport format combination (E-TFC) table is split into sub-tables. A wireless transmit/receive unit (WTRU) selects one of the sub-tables and a window within the selected sub-table to search. The WTRU then determines whether or not a first element in the search window is blocked. If the first element in the search window is blocked, then the WTRU assumes that all of the elements in the selected sub-table are blocked. If the first element in the search window is not blocked, the WTRU then determines whether a last element in the search window is blocked. If the last element is not blocked, the WTRU assumes that all elements smaller than or equal to the last element are not blocked, and all elements greater than the last element are blocked. If the last element is blocked, the size of the search window is reduced until it is determined that the last element is not blocked.

摘要： A method for performing cell reselection first determines a current cell selection quality value. The cell selection quality value is compared to a predetermined threshold. Measurements of neighboring cells are taken if the cell selection quality value is less than or equal to the predetermined threshold. Measurements can be taken of intra-frequency cells, inter-frequency cells, and inter-radio access technology cells. If a neighboring cell is found that is better than the current cell based on the measurements, then the better neighbor cell is reselected to.

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.
