Title:
APPARATUS AND METHOD FOR PERFORMING POWER HEADROOM REPORT
Document Type and Number:
WIPO Patent Application WO/2012/138089
Kind Code:
A1
Abstract:
Disclosed is an apparatus and method of performing power headroom report in a wireless communication system. Present invention includes for calculating power headroom (PH) of at least one serving cell which the MS supports, and generating a MAC message including the calculated PH, for generating or prohibiting triggering of report of the PH by considering a variation of pathloss with respect to the at least one serving cell and a varation of power backoff caused by other communication system which the MS supports, and by considering a time value received from a base station through a RRC message, and for transmitting the MAC message which includes the PH selectively based on trigger prohibition of the trigger prohibition unit. Thus, since interworking operation between triggering of PHR based on power backoff and triggering of PHR based on pathloss is defined, uplink power controlling can be effectively performed.
