Referring to Fig. 1, the process of the method for the reporting power margin of one embodiment, the execution master of this method are shown in figure
Body is terminal, the specific steps are as follows:
Step 101, when meeting the trigger condition of power headroom reporting of terminal, determine the reporting schemes of power headroom；
Optionally, in the present embodiment, trigger condition includes following any one:
It is overtime forbidding power headroom reporting (PHR) timer (prohibit PHR-Timer), and on upper primary power headroom
After report, the path loss variation amount of at least one antenna measurement of the terminal is greater than or equal to downlink path loss variable quantity
(dl-PathlossChange)；
Forbidding power headroom reporting (PHR) timer expired, and after upper primary power headroom reporting, the terminal owns
The variable quantity of the path loss statistical value (such as weighted average) of antenna measurement is greater than or equal to downlink path loss variable quantity；
Forbidding power headroom reporting (PHR) timer expired, and after upper primary power headroom reporting, the terminal owns

When periodic power headroom reports that timer (periodicPHR-Timer) is overtime.
In the present embodiment, the reporting schemes of power headroom include: to report a power headroom and report all antennas
Power headroom:
If forbidding power headroom reporting (PHR) timer expired, and after upper primary power headroom reporting, the institute of the terminal
There is the variable quantity of the path loss statistical value (such as weighted average) of antenna measurement to be greater than or equal to downlink path loss variable quantity,
True directional base station reports a power headroom；Alternatively,
If forbidding power headroom reporting (PHR) timer expired, and after upper primary power headroom reporting, the institute of the terminal
There is the statistical value of the path loss variation amount of antenna measurement to be greater than or equal to downlink path loss variable quantity, true directional base station reports
One power headroom；Or
If the reception difference of measured value of downlink signal, the assembly average of difference between the antenna of the terminal or
The change rate of person's difference is less than or equal to predetermined threshold value, and true directional base station reports a power headroom, base station can by this one
Power headroom of a power headroom as whole antennas.
If forbidding power headroom reporting (PHR) timer expired, and after upper primary power headroom reporting, the terminal
The path loss variation amount of at least one antenna measurement is greater than or equal to downlink path loss variable quantity, and true directional base station reports institute
There is the power headroom of antenna；If the system of the difference of the measured value of the reception downlink signal between the antenna of the terminal, difference
The change rate for counting average value or difference is greater than predetermined threshold value, and true directional base station reports the power headroom of all antennas.
Wherein, ratio or difference of the change rate between adjacent difference twice within a preset period of time.It should be noted that
Above-mentioned preset time period and predetermined threshold value can be configured by network side or be determined by terminal.
Optionally, above-mentioned antenna can be it is following any one: physical antenna, antenna port and aerial panel.Certainly
It is not limited to this.Refer between above-mentioned antenna: between physical antenna or between antenna port or between aerial panel.It is right
In the following 5G terminal, the mode of aerial panel is generallyd use high band antenna, such as two aerial panels are arranged.
Optionally, above-mentioned downlink signal can be downlink reference signal or down channel, such as: CRS (Cell
Reference Signal, cell reference signals), CSI-RS (channel state information reference signals), DMRS (demodulation reference letter

The second power headroom for stating the sum of the first power headroom and power offset or other antennas is equal to first power
The difference of surplus and power offset.
Assuming that terminal there are two antennas, it is individually identified as ant1 and ant2.The measured value that ant1 receives downlink signal is Pa1,
The measured value that ant2 receives downlink signal is Pa2, the difference of the measured value of downlink signal is received between antenna ant1 and antenna ant2
For delta, i.e. delta=Pa1- Pa2。
When meeting PH (power headroom) and reporting trigger condition, terminal reports the PH of antenna ant1 and antenna ant2.It reports
Mode can be following one or more:
If delta is less than predetermined threshold value, terminal only reports the PH1 of antenna ant1, and base station is using PH1 as antenna
The power headroom of ant1 and antenna ant2 carry out transmission power control.
If delta is more than predetermined threshold value, terminal reports the PH2 of the PH1 and antenna ant2 of antenna ant1.
If delta is more than predetermined threshold value, terminal reports PH1 the and power offset of antenna ant1, wherein PH2
=PH1-power offset, the power offset are antenna ant2 inclined relative to the power of the power headroom of antenna ant1
Shifting amount.
If delta is more than predetermined threshold value, terminal reports PH2 and the power offset, PH1=PH2+ of antenna ant2
Power offset, the power offset are power offset of the antenna ant1 relative to the power headroom of antenna ant2.
