Claim:
1. A method for reporting power headroom in support of multiple link connections, comprising: receiving, by a user equipment, one or more configured power headroom report parameters from at least one of multiple base stations to which the multiple link connections are connected; maintaining, at the user equipment, multiple groups of power headroom report timers corresponding to the multiple link connections respectively and maintaining multiple groups of triggering conditions for reporting power headroom corresponding to the multiple link connections respectively, wherein a number of groups of the multiple groups of the power headroom report timers and the number of groups of the multiple groups of triggering conditions for reporting power headroom are identical to the number of connections of the multiple link connections respectively; if at least one triggering condition of one group of the triggering conditions for reporting power headroom is met with respect to a corresponding base station of the multiple base stations, then calculating the power headroom for the corresponding base station and generating a power headroom report; and sending the power headroom report to the corresponding base station.
