Referring to fig. 1, a flow of a method for reporting a power headroom according to an embodiment is shown in the figure, where an execution subject of the method is a terminal, and the method includes the following specific steps:
optionally, in this embodiment, the trigger condition includes any one of:
when a prohibit PHR-Timer (prohibit PHR-Timer) is overtime and a last power headroom report is performed, a path loss variation measured by at least one antenna of the terminal is greater than or equal to a downlink path loss variation (dl-pathloss change);
when the forbidden power headroom report timer is overtime and the last power headroom report is carried out, the variation of the path loss statistic (such as weighted average) measured by all antennas of the terminal is larger than or equal to the variation of the downlink path loss;

a periodic power headroom report Timer (periodicPHR-Timer) times out.
In this embodiment, the reporting method of the power headroom includes: reporting a power headroom and reporting the power headroom of all antennas:
if the forbidden power headroom report timer is overtime and the variation of the path loss statistic (such as weighted average) measured by all antennas of the terminal is larger than or equal to the variation of the downlink path loss after the last power headroom report, determining to report a power headroom to the base station; alternatively, the first and second electrodes may be,
if the forbidden power headroom report timer is overtime and the statistic of the path loss variation measured by all antennas of the terminal is larger than or equal to the downlink path loss variation after the last power headroom report, determining to report a power headroom to the base station; or
If the difference value of the measured values of the received downlink signals between the antennas of the terminal, the statistical average value of the difference values or the change rate of the difference values is less than or equal to a preset threshold value, determining to report a power margin to the base station, and using the power margin as the power margins of all the antennas by the base station.
If the forbidden power headroom report timer is overtime and the path loss variation measured by at least one antenna of the terminal is greater than or equal to the downlink path loss variation after the last power headroom report, determining to report the power headroom of all the antennas to the base station; and if the difference value of the measured values of the received downlink signals between the antennas of the terminal, the statistical average value of the difference values or the change rate of the difference values is larger than a preset threshold value, determining to report the power margins of all the antennas to the base station.
Wherein, the change rate is the ratio or difference between two adjacent differences in a preset time period. It should be noted that the preset time period and the preset threshold value may be configured by the network side or determined by the terminal.
Optionally, the antenna may be any one of: a physical antenna, an antenna port, and an antenna panel. Of course, not limited thereto. The antenna is characterized in that: between physical antennas, or between antenna ports or between antenna panels. For future 5G terminals, the high-band antenna is usually arranged in the form of an antenna panel, for example two antenna panels.
Optionally, the downlink signal may be a downlink reference signal or a downlink channel, for example: CRS (cell reference Signal), CSI-RS (channel state information reference Signal), DMRS (demodulation reference Signal), SS (synchronization Signal), or channels such as PDCCH (physical downlink control channel) and PDSCH (physical downlink shared channel).
Alternatively, the measurement value may be RSRP (reference signal received power) or RSSI (received signal strength indicator) or the like.
In this embodiment, if the antenna is an antenna panel, the measurement value of each antenna panel may be a measurement value of the antenna panel with a receive beam forming gain, and the receive beam may be an optimal receive beam found through beam training or an optimal measurement value obtained by traversing all possible receive beams during measurement. The measurements for each antenna panel may also be measurements of the antenna panel without receive beamforming gain.
And step 102, reporting the power headroom of the antenna to a base station according to the determined reporting mode so that the base station obtains the power headroom of all antennas of the terminal according to the currently reported power headroom.
For example: if the power headroom is determined to be reported to the base station, the terminal reports the power headroom to the base station, and the base station takes the obtained power headroom as the power headroom of all the antennas.
If the power headroom of all the antennas is determined to be reported to the base station, the terminal reports the power headroom of all the antennas to the base station, and the mode of reporting the power headroom of all the antennas is as follows:
sending the identification of each antenna in all the antennas and the power headroom of the antenna corresponding to the identification to a base station; or, sending the first power headroom of a first antenna in all antennas and the power offset of other antennas in all antennas relative to the first power headroom of the first antenna to a base station; and the second power headroom of the other antenna is equal to the sum of the first power headroom and the power offset, or the second power headroom of the other antenna is equal to the difference between the first power headroom and the power offset.
Assume that the terminal has two antennas, identified as ant1 and ant2, respectively. ant1 receives the downstream signal with the measured value Pa1The measured value of the received downlink signal of ant2 is Pa2The difference between the measured values of the received downlink signals between the antenna ant1 and the antenna ant2 is delta, that is, delta is Pa1－Pa2。
When the PH (power headroom) reporting trigger condition is satisfied, the terminal reports the PHs of the antenna ant1 and the antenna ant 2. The reporting mode may be one or more of the following:
if delta does not exceed the preset threshold value, the terminal only reports PH1 of antenna ant1, and the base station takes PH1 as the power margin of antenna ant1 and antenna ant2 to control the transmission power.
And if the delta exceeds a preset threshold value, the terminal reports the PH1 of the antenna ant1 and the PH2 of the antenna ant 2.
If delta exceeds a preset threshold, the terminal reports PH1 and power offset of the antenna ant1, wherein PH2 is PH 1-power offset, and the power offset is the power offset of the antenna ant2 relative to the power margin of the antenna ant 1.
If delta exceeds the preset threshold, the terminal reports the PH2 and power offset of the antenna ant2, and PH1 is PH2+ power offset, and the power offset is the power offset of the power margin of the antenna ant1 relative to the antenna ant 2.
In this embodiment, when a trigger condition for reporting the power headroom of the terminal is satisfied, it is determined whether to report one power headroom or report the power headroom of all antennas, so that the base station can correctly know the power headroom of other antennas through the power headroom of the currently reported antenna, thereby continuing power control and avoiding interruption of uplink data transmission.

if the statistics of the path loss variation measured by all antennas of the terminal is greater than or equal to the downlink path loss variation after the forbidden power headroom report timer is overtime and the last power headroom report is carried out; and
a periodic power headroom report Timer (periodicPHR-Timer) times out.
Optionally, in this embodiment, the manner of determining the power headroom of all the antennas of the terminal according to the power headroom is as follows: and taking a power margin reported by the terminal as the power margins of all antennas of the terminal.
