20、1.9051. CA_x-y Inter-band Carrier Aggregation of Band x and Band y4 BackgroundThe present document is a technical report for Inter-band Carrier Aggregation under Rel-11 time frame. It covers both the UE and BS side. The document is divided in two different parts:- Common part: this part covers BS an
21、d UE specific which is band combination independent. - Specific band combination part: this part covers each band combination and its specific issues independently from each other (i.e. one subclause is defined per band combination)The specific band combination parts are independent and therefore, t
22、he working speed also differs. Annex A contains a list of all CA combinations covered in the present document as well as the status of each WI. The content of each specific combination part can be considered as finalized when the current status of the WI under Annex A is indicated as “Closed”.4.1 TR
23、 MaintenanceA single company is responsible for introducing all approved TPs in the current TR, TR editor. However, it is the responsibility of the rapporteur of each WI to ensure that the TPs related to the WI have been implemented. 5 Inter-band Carrier Aggregation: general part5.1 BS specific Ther
24、e are four categories of inter-band CA combinations for UE. For BS, it is typical that different RF modules are used for different bands. Thus, the categories for BS could be simpler than those for UE. The requirements are mainly affected by the BS antenna configurations. Currently, the wide band an
25、tenna can support 1.8 GHz to 2.6 GHz frequency range. For the bands lower than 1 GHz, a separate antenna is needed. For the approved inter-band CA combinations, the low-high band combinations using separate antennas can be treated as one category. The situation for these combinations is similar as c
26、urrent non-CA but co-located BSs. The requirements are covered by current specifications in this scenario. The other category is the band combinations which can use the same antenna. The new issue raised in the antenna sharing scenario is the possible passive intermodulation. 5.2 UE specific 5.2.1 C
