摘要： The dynamic determination of a handover trigger for triggering handover of a mobile terminal in a wireless network from a source base station to a target base station is based on one or more Key Performance Indicators (KPIs). Each KPI indicates a quality of wireless services provided by the wireless network responsive to a particular handover trigger. If an obtained parameter that indirectly or directly impacts handover performance passes a corresponding performance test, the mobile terminal selects the handover trigger based on the KPIs. If the parameter fails the corresponding performance test, the source base station selects the handover trigger based on the KPIs.

摘要： Techniques for facilitating and performing frequency-offset estimation are disclosed. The disclosed techniques include methods and apparatus for maintaining phase coherence among reference symbols on different transmission-time intervals (TTI) for an accurate estimation of frequency offset. Corresponding techniques utilize channel estimation or measurements of channel-related parameters based on multiple reference symbols belonging to different TTIs. An example method in a radio transceiver for facilitating frequency offset estimation at a remote receiver begins with determining that phase coherence between reference symbol transmissions in a first TTI and a second TTI is required. The radio transceiver selectively maintains phase coherence between reference symbol transmissions in the first and second TTIs, in response to said determining. The radio transceiver then transmits during at least part of a third TTI, following the second TTI, without maintaining phase coherence to the reference symbol transmissions in the first and second TTIs.
