(EN) A method and device for indicating a power headroom report (PHR) the method comprising: a user equipment (UE) first determining a power headroom report then sending same to a base station during a random access process; the PHR can be borne by a related information segment of a Message 3 sent by the UE to the base station. The present solution can enable a base station to acquire in a timely manner a basis for performing scheduling configuration for a current UE uplink data transmission so that power control and scheduling information is more accurately configured for the UE thus avoiding uplink bandwidth waste caused by allocation to a UE of a channel exceeding the uplink transmission capability of same.
