摘要： This document discusses a method and device for initiating cell measurement. An initiating condition for initiating the measurement of a Closed Subscriber Group (CSG) cell and/or a Hybrid cell is preset by the network side. The measurement of the CSG cells and/or Hybrid cells is initiated by a User Equipment (UE) when the initiating condition is satisfied. The UE automatically initiates the measurement of the CSG cell and/or Hybrid cell when the UE is close to its own footprint area or fingerprint area.

摘要： A method and apparatus are disclosed for reporting a power headroom report (PHR) in a carrier aggregation scenario. The method includes the following steps: when a user equipment (UE) reports the PHR in a scenario where a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) can be transmitted concurrently, if no PUSCH is transmitted over the Uplink Primary Component Carrier (UL PCC) configured by an eNB for the UE, then a virtual type1 PH and/or a virtual type2 PH corresponding to the UL PCC are reported; if a PUSCH rather than a PUCCH is transmitted over the UL PCC configured by the eNB for the UE, then the type1 PH corresponding to the UL PCC is reported or the virtual type2 PH and the type1 PH corresponding to the UL PCC are reported. User equipment is also disclosed.
