FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication. The invention provides a method, an apparatus and a computer-readable medium for wireless communication in which the difference between a previous power management maximum power reduction (P-MPR) and a current P-MPR is determined. The previous P-MPR is the P-MPR when an indication is transmitted that a power reduction is applied due to the previous P-MPR. A power headroom report (PHR) is triggered when the difference is greater than a threshold and the current P-MPR is greater than the sum of a maximum power reduction (MPR) and an additional MPR (A-MPR). Moreover, an apparatus is provided in which whether and how a P-MPR has changed is indicated in a PHR, and the PHR is transmitted. An apparatus is also provided in which a request is received from an evolved Node B (eNodeB) to report a P-MPR, and a PHR is transmitted including information related to the P-MPR.
EFFECT: power management maximum power reduction.
