METHOD AND APPARATUS FOR REPORTING POWER HEADROOM

摘要

Embodiments of the present disclosure provide a method and apparatus for reporting power headroom. The method includes: transmitting a power headroom report message by UE to an eNB when a report condition of PH is satisfied, related information in the power headroom report message which corresponds to a carrier multiplexed with a D2D link including a PH value of the D2D link and a PH value of a cellular link; wherein an order of the PH value of the D2D link and the PH value of the cellular link in the power headroom report message is predefined according to system configuration. With the method and apparatus of the embodiments, the UE may accurately and/or punctually report power headroom of the D2D link to the eNB. Therefore, the eNB may schedule the resources of the D2D link and the cellular link more flexibly and effectively.
