  • Position determination method and device, and computer storage medium
    Patent number: 9930630
    Abstract: The present disclosure discloses a method and device for determining a position, and a computer storage medium. The method includes that a first power value for a SYNC-NL segment within a DwPTS, a second power value for a first GP segment which precedes the SYNC-NL segment, a third power value for a second GP segment which follows the SYNC-NL segment, and a fourth power value for a time slot 0 are acquired; an eigenvalue of the DwPTS is calculated according to the first power value, the second power value, the third power value and the fourth power value; and the position of the DwPTS is determined according to the eigenvalue.

  • INDICATION INFORMATION CORRECTION METHOD, SYSTEM AND STORAGE MEDIUM
    Publication number: 20170374571
    Abstract: A method for correcting indication information is described; the method includes that: a Signal-to-Noise Ratio (SNR) value of a first layer at current time and an SNR value of a second layer at the current time are obtained; a channel correlation value at the current time is calculated according to the SNR value of the first layer and the SNR value of the second layer; a smoothing value of the channel correlation value at the current time is calculated according to the calculated channel correlation value and a preset forgetting factor; and a Rank Indicator (RI) value and/or a Channel Quality Indicator (CQI) value are/is corrected according to the obtained smoothing value. A system and a storage medium for correcting indication information are also described.
