摘要： An inter-system handover system for a wireless communication system supports hand-down and hand-up of user equipment (UE) to different radio access technologies, including synchronous and asynchronous systems. Latency and handover connection failures are reduced by an access node (nodeB) broadcasting information about neighboring systems (targets) when the UE reception (RX) capability is both inside or outside the reception range of the target. A single RX chain is sufficient, although transitioning between a wireless wide area network (WWAN) to a wireless local area network may (WLAN) may advantageously benefit from simultaneous operation on two Rx chains. Optimized list of neighboring RAT systems (targets) are broadcast from the network, including measurement parameters and reporting instructions. Thereby, UE-driven reporting minimizes latencies. UE reports other-system searches to network only if needed for a handover. In addition, handover requests can be bundled with other-system measurement information, if necessary, for additional efficiencies.

摘要： Described herein are mechanisms and methods that facilitate preparation of inter-radio access technology (inter-RAT) and/or inter-frequency handover with respect to a mobile device (user equipment). User equipment can indicate to a network servicing the user equipment that the user equipment desires to perform measurements with respect to a different frequency and/or different technology. Data on the downlink channel can then be scheduled to ensure that data intended for the user equipment is not lost while the user equipment is performing the measurements.

摘要： Techniques for performing handover in order to maintain call continuity for a user equipment (UE) are described. The UE may communicate with a first cell in a radio access network (RAN) for a packet-switched (PS) call, e.g., for Voice-over-Internet Protocol (VoIP) via High-Speed Packet Access (HSPA) in W-CDMA. The UE may send measurement reports to the RAN and may receive trigger from the RAN. The UE may establish a circuit-switched (PS) call with the first cell while the PS call is pending at the first cell. The PS call and the CS call may be for a voice call, and the UE may switch data path for the voice call from the PS call to the CS call and then terminate the PS call. The UE may then perform handover of the CS call from the first cell to a second cell, which may not support VoIP.

摘要： System(s) and method(s) are provided for inter-cell interference management in a wireless communication system. A base station perform interference management by conveying and receiving load indicator messages over a backhaul communication link to disparate neighboring base stations that serve interfering mobile stations. Reporting of load indicators takes place according to a reporting policy that is event-based, and accounts for variations of interference metrics over available time-frequency resources. Communication with neighboring base stations is limited to a monitoring interference set, which can be determined statically, according to deployment characteristics of a wireless network, or the set can be adjusted dynamically according to a set of received UL signals or a set of DL CQI measurement reports. Reporting policy and interference set can be autonomously adapted to optimize backhaul traffic as well as interference control.

摘要： Techniques for supporting communication on multiple carriers are disclosed. In one design, a user equipment (UE) is configured with a base carrier and a dependent carrier linked to the base carrier. Data transmission on the dependent carrier is scheduled via a scheduling carrier, which is different from the dependent carrier. The UE receives a scheduling grant on the scheduling carrier and determines whether the scheduling grant is for the base carrier and/or the dependent carrier. The UE communicates (e.g., sends or receives data) on the base carrier and/or the dependent carrier based on the scheduling grant. The scheduling grant may be (i) a separate grant carrying scheduling information for only one carrier, (ii) a common grant carrying scheduling information for both carriers, (iii) a joint grant carrying separate scheduling information for each carrier, or (iv) a composite grant that may be a separate grant, a common grant, or a joint grant.
