Method for acquiring signal to noise ratio, signal receiving device and signal sending device

摘要

Embodiments of the present invention provide a method for acquiring a signal to noise ratio (SNR), a signal receiving device and a signal sending device. Through the embodiments of the present invention, an SNR of the signal receiving device (i.e., a receiving end) can satisfy the setting requirement, that is, the test condition that an SNR does not contain a precoding gain, so that a subsequent test is valid.

1. A method for acquiring a signal to noise ratio, the method comprising:
receiving a first noise signal on at least one first resource element and receiving, on the at least one first resource element, first data sent by a sending end, wherein the first data is data before precoding; obtaining a first signal to noise ratio according to signal receiving power of the first data received on the at least one first resource element and according to first power of the first noise signal received on the at least one first resource element; and receiving, on at least one second resource element, the first data having signal transmit power adjusted, and/or receiving, on the at least one second resource element, the first noise signal having signal transmit power adjusted, and obtaining a second signal to noise ratio according to the following manner: obtaining a second signal to noise ratio according to signal receiving power of the first data that has the signal transmit power adjusted and is received on the at least one second resource element and according to the first power of the first noise signal received on the at least one first resource element; or obtaining a second signal to noise ratio according to signal receiving power of the first data that has the signal transmit power adjusted and is received on the at least one second resource element and according to power of the first noise signal that has the signal transmit power adjusted and is received on the at least one second resource element; or obtaining a second signal to noise ratio according to the signal receiving power of the first data received on the at least one first resource element and according to power of the first noise signal that has the signal transmit power adjusted and is received on the at least one second resource element.
