【文章內(nèi)容簡(jiǎn)介】 covers both the UE and BS side. The document is divided in two different parts: Common part: this part covers BS and UE specific which is band bination independent. Specific band bination part: this part covers each band bination and its specific issues independently from each other (. one subclause is defined per band bination)The specific band bination parts are independent and therefore, the working speed also differs. Annex A contains a list of all CA binations covered in the present document as well as the status of each WI. The content of each specific bination part can be considered as finalized when the current status of the WI under Annex A is indicated as “Closed”. TR MaintenanceA single pany 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 Interband Carrier Aggregation: general part BS specific There are four categories of interband CA binations 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 antenna can support GHz to GHz frequency range. For the bands lower than 1 GHz, a separate antenna is needed. For the approved interband CA binations, the lowhigh band binations using separate antennas can be treated as one category. The situation for these binations is similar as current nonCA but colocated BSs. The requirements are covered by current specifications in this scenario. The other category is the band binations which can use the same antenna. The new issue raised in the antenna sharing scenario is the possible passive intermodulation. UE specific Class A1.

Lowhigh band bination with harmonic relation between bands Class A3. Lowlow or highhigh band bination without intermodulation problem (low order IM) Class A4. Lowlow or highhigh band bination with intermodulation problem (low order IM) Class A5. Combination except for A1 – A4 RRM specific Class A1. Lowhigh band bination without harmonic relation between bandsAll interband carrier aggregations that belong to Class A1. Lowhigh band bination without harmonic relation between bands shall follow the requirements defined in this section unless explicitly stated otherwise.The UE measurement requirements, including OTDOA RSTD, for carrier aggregation specified in subclause and in TS for primary ponent carrier and secondary ponent carrier are defined in a band agnostic manner. The measurement accuracy requirements, including OTDOA RSTD, for carrier aggregation, as defined in subclause and in TS for primary ponent carrier and secondary ponent carrier are also in a band agnostic manner. Since there is no change on reference sensitivity power level (ΔRib= 0 dB) for 2 DL/1 UL for Class A1 CA binations, there is no need to define additional measurement requirements specific for Class A1 CA binations for 2 DL/1 UL cases.6 Interband Carrier Aggregation: band bination specific part Class A1.
