1. a kind of method that terminal in mobile communication system obtains power margin information, this method comprises:

  • The information that the path loss for receiving the related secondary cell for triggering power headroom reporting (PHR) PHR from base station refers to, wherein instituteState the serving cell in information instruction main plot and the secondary cell;

    If the downlink path-loss variation of indicated serving cell is more than threshold value, PHR is triggered;

    AndBased on if there is the uplink resource for being allocated for new transmission, the power headroom of the cell of each activation is obtainedInformation;

    Wherein, the PHR includes power headroom PH and indicator, and the indicator indicates that the PH is to be based on really physicallyInk Shared Channel (PUSCH) transmission is still based on parameter format.
