Method, user equipment, base station and system for measuring signal received power

A base station, comprising:

• a processor, configured to configure reference signal resource;
• and
• a transmitter, configured to send one of a reference signal subset, and a reference signal subset and a precoding matrix, to a user equipment (UE), so as to enable the UE to obtain signal received power based on one of the reference signal subset, and the reference signal subset and the precoding matrix;
• wherein the reference signal subset is a subset of a reference signal port set configured in the reference signal resource.

A system, comprising a base station (eNB), and a user equipment (UE),

• the base station comprising:
• a processor, configured to configure reference signal resource;
• and
• a transmitter, configured to send one of a reference signal subset, and a reference signal subset and a precoding matrix, to a user equipment (UE), so as to enable the UE to obtain signal received power based on one of the reference signal subset, and the reference signal subset and the precoding matrix;
• wherein the reference signal subset is a subset of a reference signal port set configured in the reference signal resource;
• and
• the user equipment, comprising:
• a receiver, configured to obtain reference signal resource;
• and
• a processor, configured to obtain a reference signal subset and a precoding matrix, and obtain signal received power according to the reference signal subset and the precoding matrix, wherein the reference signal subset is a subset of a reference signal port set configured in the reference signal resource, and the precoding matrix is used for precoding the reference signal subset.
