Description
Technical field
Carrier aggregation (CA, the Carrier Aggregation) communication technology in the long evolving system (LTE-A, LTE-Advanced) that the present invention relates to strengthen relates in particular to processing method and the device of carrier aggregation self-interference between a kind of frequency range.
Background technology
In order to satisfy (the ITU of International Telecommunications Union, International Telecommunications Union) following peak rate requirement, the maximum 100MHz bandwidth of the current support of LTE-A, yet in existing usable spectrum resource, be difficult to find so large bandwidth, and large bandwidth is brought very large difficulty for the hardware designs of base station and terminal.In addition, for the frequency spectrum resource that is dispersed on a plurality of frequency ranges, need a kind of technology badly they are fully utilized.Based on above-mentioned consideration, LTE-A introduces this key technology of carrier aggregation.
Carrier aggregation can be divided in the frequency range (inter-band) carrier aggregation between (intra-band) carrier aggregation and frequency range according to the frequency range difference of its polymerization.Therefore the polymerization of frequency range intercarrier just the problem that uplink and downlink signals interferes with each other can not occur as long as duplexer is reasonable in design owing to uplink and downlink signals after its polymerization still is in the same frequency band.But in the situation of carrier aggregation between frequency range, because uplink and downlink signals is on the different frequency ranges, it is very complicated that the impact between them can become.Be in emission (TX, Transmit) neighboring trace of certain frequency range of state, harmonic wave or intermodulation product may drop into another one and receive (RX, Receive) frequency range, may cause interference like this, this interference is owing to produce between the TX of carrier aggregation itself and the RX, does not belong to external interference, and is general in order to distinguish the self-interference problem that can be called carrier aggregation, because this interference does not have path loss, generally its interference problem that causes is all more serious.For example, for the carrier aggregation terminal of band support (band) 4 and band17, because the band4 corresponding frequency band is: up 1710MHz～1755MHz, descending 2110MHz～2155MHz; And the band17 corresponding frequency band is: up 704MHz～716MHz, and descending 734MHz～746MHz, the up triple-frequency harmonics of band17 can drop in the band downlink of band4 like this, causes the descending interference to band4.If this self-interference problem does not solve, can affect the performance of carrier aggregation, cause the communication loss, serious, may cause this communicating interrupt.The problems referred to above are not limited only to terminal (UE, User Equipment) side in addition, and there is this problem too in (eNB, evolved Node B) side in the LTE base station.
Carrier aggregation can well be utilized frequency spectrum resource between frequency range, improve transmission rate, its application prospect has obtained the favor of increasing operator, application along with carrier aggregation between more and more frequency ranges, the self-interference problem of carrier aggregation between above-mentioned frequency range can become more and more outstanding and inevitable.But also there is not a kind of good method to solve this problem at present.
