Description
Technical field
The present invention relates to the communications field, in particular to a kind of report method, base station and terminal of secondary power rollback value.
Background technology
Along with the development of mobile communication, with carrier aggregation, relaying (Relay), what the technology such as multipoint cooperative were representative is senior long-termEvolution (LongTermEvaluation-advanced, referred to as LTE-A), as the enhancing version of LTE, has obtained rapidlyDevelopment. LTE-Advanced requires to provide descending 1Gbit/s, the peak value speed of up 500Mbit/s in the bandwidth of 100MHzRate. In order to work in so wide bandwidth, LTE-Advanced has introduced carrier aggregation technology. Application carrier aggregation technology,The frequency spectrum resource of dispersion can be integrated by the mode of polymerization, obtain larger bandwidth (being greater than 20MHz), higher numberAccording to speed, thereby greatly promote the development of mobile communication. Consider and the backwards compatibility of LTE, LTE-Advanced introducesThe concept of member carrier, the maximum bandwidth of each member carrier is no more than 20MHz, corresponding with the bandwidth class of LTE.
But due to the application of carrier aggregation technology, the power expending after multiple carrier aggregation is large obviously than single carrier time,This has just had higher requirement to the overall performance of LTE-advanced system. At multiple frequency bands, the feelings that multiple member carriers existUnder condition, between each carrier wave, there is intermodulation, if intermodulation drops on outside band, also can raise out-of-band radiation, if need to making an uproar systemSound and radiation control, need to be by values certain maximum transmission power rollback in certain limit. As long as there is the scene of carrier aggregation,Will produce the back-off of this general types. That is to say, in carrier aggregation this merit all must be set in any caseRate rollback.
Multiple separate member carriers separately must need certain device to connect physically, as various types of duplexsDevice, wave filter etc. Can increase like this insertion loss of radio system, affect generally the form of noise of system, make the band of systemInterior noise and out-of-band radiation increase. Address this problem, also need value certain the peak power rollback of system, Cai NengmanThe requirement of foot spectrum mask and out-of-band radiation. And this insertion loss is not whenever the having of carrier aggregation scene,Just the scene of polymerization between frequency exists, so need to consider how to make in-band noise and out-of-band radiation under this special sceneReach within the scope of regulation.
