Abstract:
A method for controlling uplink transmissions on discontinuous reception (DRX) operation, by a wireless device, in a wireless communication system, the method comprising: configuring a channel quality indicator (CQI)-masking which indicates that at least one of a CQI, a precoding matrix index (PMI), a rank indicator (RI), or a precoding type indicator (PTI) is not to be reported on a physical uplink control channel (PUCCH) when an onDurationTimer is not running; and determining, at a first subframe prior to a second subframe, whether or not the onDurationTimer is to be running at the second subframe, wherein the at least one of the CQI, the PMI, the RI, or the PTI is not to be reported on the PUCCH at the second subframe, if the onDurationTimer is determined, at the first subframe, to be not running at the second subframe.

Abstract:
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 UE (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.
