摘要:
A method and apparatus for discontinuous reception (DRX) operation in a wireless transmit receive unit aligns uplink and downlink transmissions with a DRX cycle. The transmission may be a channel quality indicator report, a sounding reference signal, or a silence descriptor among other downlink and uplink transmissions.

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 apparatus for adaptive handover includes receiving a time to trigger (TTT) for a first mobility state. A scaling factor is received for a second mobility state. The TTT for the second mobility state is determined by scaling the first mobility state with the scaling factor for the second mobility state.

A method for radio resource control (RRC) messaging. The messaging includes transmitting a RRC message upon partial completion of message transmission. The RRC message further comprises an information element (IE) that represents a failed or partially failed condition.
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 WTRU configured to receive a multicast, a unicast or mixed signal. A multimedia signal may be a Multimedia Broadcast Multicast Signal (MBMS). The WTRU switches between an MBMS and a mixed signal and determines optimal time to switch between the MBMS and mixed signal. The WTRU switches between receiving the MBMS and mixed signal in an adaptive or semi-static pattern. A flat broadcast channel (BCH) structure in an MBMS dedicated cell is provided, eliminating need for a dedicated broadcast channel (D-BCH). An MBMS-dedicated cell uses a single paging channel for both paging-indicators and paging-record-blocks. A system information broadcast indicates flexible resource usage and paging-record-block limits. Tracking area (TA)/cell association is provided for an MBMS-dedicated cell and geographically co-located non-MBMS-dedicated cells. MBMS-dedicated cell system information is broadcast to regulate WTRU operation while receiving MBMS within said cell. Generic Access Profile (GAP) definitions is part of system information.

A method and apparatus are disclosed for communicating with a Wireless Transmit/Receive Unit in wireless communications. The WTRU, capable of communicating in a 3GPP network and a non-3GPP network, receives messages with the assistance of the non-3GPP network through a Paging Entity.
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:
A method for assigning a tracking area (TA) is disclosed. A mobility state of a wireless transmit/receive unit (WTRU) is determined and the TA is assigned based on the determined mobility state. Also disclosed is a method for accessing a closed subscriber group (CSG) TA. A CSG TA identifier is received at a WTRU and is stored. A CSG TA broadcast is received and the broadcast CSG TA is accessed if an identifier of the broadcast CSG TA matches the stored CSG TA identifier. Also disclosed is a method for changing a mobility state of a WTRU. A current mobility state of the WTRU is determined and a predetermined metric of the WTRU is examined. The predetermined metric is evaluated to determine if the metric has crossed a threshold and the mobility state is changed based on the evaluated metric.
摘要:
A method for controlling behavior of lower layer links related to media independent handover (MIH) of a mobile user comprises sending a MIH link actions request primitive from a MIH User entity to a MIH function (MIHF) for requesting actions to be executed on a set of lower layer links to heterogeneous radio access technology (RAT) networks. The primitive includes parameters that indicate the requested actions and an execution time delay. Confirmation primitives are sent back the MIH User entity to convey the results of the execution attempts on the requested actions.
