Systems and methods for reporting pilot signal power information in a four branch MIMO system

摘要

A base station, comprising a first antenna for transmitting a first pilot signal; a second antenna for transmitting a second a pilot signal; a third antenna for transmitting a third pilot signal; and a fourth antenna for transmitting a fourth pilot signal. The base station is configured to transmit pilot signal power information for indicating power values to a user equipment, UE, receiving the pilot signal power information. The pilot signal power information comprises: a first power value corresponding to the first pilot signal, a second power value corresponding to the second pilot signal, a third power value corresponding to the third pilot signal, and a fourth power value providing information regarding at least two demodulation pilot signals.

1. A base station, comprising:
a first antenna for transmitting a first pilot signal using a first transmit power; a second antenna for transmitting a second a pilot signal using a second transmit power; and a third antenna for transmitting a third pilot signal using a third transmit power, wherein the base station is configured to transmit a control message comprising: first transmit power data for identifying the first transmit power, second transmit power data for identifying the second transmit power, third transmit power data for identifying the third transmit power, and fourth transmit power data providing transmit power information concerning at least two demodulation pilot signals, wherein the first transmit power data is separate and distinct from the second, third and fourth transmit power data, the second transmit power data is separate and distinct from the third and fourth transmit power data, and the third transmit power data is separate and distinct from the fourth transmit power data.
