Methods and apparatuses for measuring pilot

摘要

A pilot measurement method is provided, which includes that a receiving end determines a port configuration for pilot measurement, and the receiving end receives a pilot signal using the port configuration, and obtains channel information upon an estimate. Correspondingly, a receiving end for pilot measurement is also provided. Even though the number of antenna ports is sharply increased, a part of ports still can be selected as the ports for transmitting a pilot signal according to needs, the number of the ports for transmitting the pilot signal can be unlimited, and the pilot configuration problem under the condition of sharp increase in the number of the antenna ports can be solved.

1. A pilot measurement method, comprising:
determining, by a receiving end, a port configuration for pilot measurement; and receiving, by the receiving end, a pilot signal using the port configuration, and obtaining channel information upon an estimate, wherein after determining, by the receiving end, the port configuration for pilot measurement, the method further comprises: receiving, by the receiving end, corresponding time-domain configuration information and/or frequency-domain configuration information from a transmitting end after the transmitting end determines a time-domain configuration and/or a frequency-domain configuration corresponding to the port configuration, wherein the time-domain configuration is that a specified port configuration is applied to a specified subframe or radio frame or Orthogonal Frequency Division Multiplexing (OFDM) symbol; the frequency-domain configuration is that a specified port configuration is applied to a specified bandwidth or sub-band or Resource Block Group (RBG) or Resource Block (RB), wherein when there are totally N rows and N columns of ports (N is an integer not smaller than 1), the port configuration comprises N port configurations, wherein a nth port configuration is that ports in a nth row and ports in a nth column are configured to transmit or receive the pilot signal, and n is an integer not greater than N and not smaller than 1; and the time-domain configuration is that the N port configurations are applied to N specified subframes or radio frames or OFDM symbols, one port configuration is applied to one subframe or radio frame or OFDM symbol, and a same port configuration or different port configurations is or are applied to different subframes or radio frames or OFDM symbols.
