Embodiments of the present invention disclose a method, an apparatus, and a system for processing a reference signal. The present invention relates to the field of radio communications technologies, and solves a technical problem that it is impossible to meet a requirement for measurement of downlink channels of multiple cells in a coordinated multipoint transmission/reception (CoMP) scenario in the prior art. According to the embodiments of the present invention, a reference signal is sent in a specified pilot position to a target user equipment (UE) where data puncturing is performed, in positions corresponding to the specified pilot position, with respect to data symbols simultaneously sent by an evolved NodeB (eNB) to which another cell in a CoMP set of the UE belongs, and the specified pilot position is orthogonally separated from a reference signal pilot position of the another cell in the CoMP set.

Embodiments of the present invention provide a method and an apparatus for performing channel measurement for a cell. The method includes: sending information about a location of a to-be-measured reference signal to a user equipment, where the location of the to-be-measured reference signal is a part of a location occupied by a reference signal of the cell; and receiving a channel measurement report of the cell. The channel measurement report is sent by the user equipment and is obtained after the user equipment performs channel measurement for the cell according to the information about the location of the to-be-measured reference signal.
摘要:
A resonant power converter is disclosed with a driving circuit generating a switching signal connecting power to a resonant tank circuit, with a voltage monitoring circuit measuring a voltage output and a load current. A micro-controller is operable with a control circuit for multiple step sampling with the switching signal at a switching frequency to settle the resonant circuit determined from the voltage output and load current. A fast load transient response at a high frequency with the resonant circuit provides the multiple step sampling to ensure enough time for micro-controller to calculate. Optimal trajectory control facilitates a burst mode of high frequency with the resonant circuit using adaptive multiple step sampling for an on-time to extend the burst operation range. A soft start-up process uses the micro-controller processing in multiple stages.
