摘要:
A wireless transmit/receive unit (WTRU) prioritizes triggered events for the same measurement object to lessen the quantity of events which are included in measurement reports, while conveying no less information. The WTRU triggers an event, starts a time-to-trigger timer for the event, and includes the event in a measurement report. Additionally, where a WTRU measures on multiple frequencies, the event triggering is prioritized according to priorities associated with the frequencies.
摘要:
A method and apparatus for a wireless transmit receive unit (WTRU) to receive system information updates. This includes the WTRU aligning a discontinuous reception (DRX) on-duration with a system information update cycle such that the system information update cycle is a multiple of a DRX cycle.
摘要:
A method and apparatus for a wireless transmit receive unit (WTRU) to receive an emergency situation notification. The method and apparatus include the WTRU receiving a paging message with an emergency situation notification, and the WTRU receiving scheduling information in a system information block.
摘要:
A method for applying a priority of a closed subscriber group (CSG) cell, including receiving priority information for each of a plurality of communication frequencies over which the CSG cell can communicate; storing the priority information at a wireless transmit/receive unit; and applying the priority information to at least one of: taking measurements on a communication frequency, selecting to a CSG cell in the communication frequency, or reselecting to a CSG cell in the communication frequency.
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.
摘要:
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.
摘要:
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.
