Method, apparatus, and system for processing reference signal

摘要

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.

1. A method for processing a reference signal, comprising:
sending, by an evolved NodeB (eNB) of a cell belonging to a coordinated multipoint transmission/reception (CoMP) set in a specified pilot position, a reference signal to a target user equipment (UE), and performing data puncturing with respect to data symbols that are simultaneously sent by an eNB of another cell in the CoMP set in positions corresponding to the specified pilot position; and obtaining the reference signal pilot position of the another cell in the CoMP set; wherein, the specified pilot position is orthogonally separated from a reference signal pilot position of another cell in the CoMP set; wherein the another cell is a cell other than a cell corresponding to the specified pilot position; and wherein the step of obtaining the reference signal pilot position of the another cell in the CoMP set comprises:
negotiating with the eNB of the another cell in the CoMP set about the reference signal pilot position of the another cell in the CoMP set, wherein reference signal pilot positions of cells of the CoMP set after the negotiation are orthogonally separated in a time-frequency domain multiplexing mode; andsending information comprising rising a reference signal pilot position of a particular cell to the eNB of the another cell in the CoMP set; and wherein, the specified pilot position is the reference signal pilot position of the particular cell after negotiation.
