Measurement method and apparatus

摘要

The disclosure discloses a measurement method. The method includes: a conjugate multiplication operation is performed on reference signals corresponding to a subcarrier within adjacent time slots to remove phase interference of the reference signals; the reference signals from which the phase interference has been removed are descrambled; and all the descrambled reference signals are accumulated. The disclosure further provides a measurement apparatus. With the technical solution of the disclosure, the operation complexity of measurement can be reduced.

1. A measurement method in a receiver, comprising:
performing, by a remover, a conjugate multiplication operation on reference signals received at the receiver from a base station corresponding to a subcarrier within adjacent time slots to remove phase interference of the reference signals; descrambling, by a descrambler, the reference signals from which the phase interference has been removed; and accumulating, by an accumulator, all the descrambled reference signals; wherein the descrambling the reference signals from which the phase interference has been removed comprises:
constructing, by the descrambler, a descramblinq sequence RS(k)=RS*t,l(k)·RSt+1,l(k), where RS*t,l(k) and RSt+1,l(k) represent a conjugate signal of a reference signal sent on a k-th subcarrier in an l-th symbol within time slot t and a reference signal sent on the k-th subcarrier in the l-th symbol within time slot t+l by the base station respectively; andmultiplying a reference signal R(k) from which the phase interference has been removed by the descrambling sequence RS(k) to obtain {circumflex over (R)}(k)=RS(k)·R(k).
