Triggering power headroom reporting in TDD system
The present invention relates to a wireless communication system. More specifically, the present invention relates to triggering conditions for power headroom reporting (PHR) in a wireless network employing TDD scheme. According to one aspect of the present invention, the a user equipment (UE), receives information informing the UE of multiple time division duplex (TDD) uplink/downlink (UL/DL) subframe configurations and information on a threshold value for a power headroom reporting (PHR). And, the UE triggers a power headroom reporting (PHR), when a required power backoff due to a power management for any of the multiple TDD UL/DL subframe configurations has changed more than the threshold value.
