METHOD AND APPARATUS FOR REPORTING A POWER HEADROOM REPORT (PHR) IN A CARRIER AGGREGATION SCENE

摘要

Disclosed are a method and apparatus for reporting a power headroom report (PHR) in a carrier aggregation scene. The method comprises the following steps: when a user equipment (UE) reports the PHR in a scene where a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) can be transmitted concurrently, if the UL PCC configured by an eNB for the UE has no PUSCH to transmit, then the UE reports virtual type 1 PH and/or virtual type 2 PH corresponding to the UL PCC; if the UL PCC configured by the eNB for the UE has a PUSCH but no PUCCH to transmit, then the UE reports the type 1 PH corresponding to the UL PCC or the type 1 PH and the virtual type 2 PH corresponding to the UL PCC. A UE is also disclosed. The present invention provides the corresponding method for reporting the PHR in different scenes, and provides a basis for the eNB to better perform uplink scheduling.
