根據(jù)TS38.306定義 終端支持的DMRS，PUCCH、跳頻和CORESET如下：

phy-ParametersFRX-Diff {
       twoFL-DMRS '10'B,
       supportedDMRS-TypeDL type1,
       supportedDMRS-TypeUL type1,
       pucch-F2-WithFH supported,
       pucch-F3-WithFH supported,
       pucch-F1-3-4WithoutFH notSupported,
       almostContiguousCP-OFDM-UL supported,
       multipleCORESET supported,
       mux-SR-HARQ-ACK-CSI-PUCCH-OncePerSlot {
           sameSymbol supported
      },
      oneFL-DMRS-TwoAdditionalDMRS-UL supported
      },

 

以上參數(shù)的定義如下： 

twoFL-DMRS (MappingTypeB, DMRS length = 2) ： 無論UE支持的DM-RS 在上/下行傳輸時使用2個符號中均有MD-RS；




Defines whether the UE supports DM-RS pattern for DL reception and/or UL transmission with 2 symbols front-loaded DM-RS without additional DM-RS symbols.




twoFL-DMRS-TwoAdditionalDMRS：在DM-RS 在上/下行傳輸時使用2個符號中MD-RS外還可以額外配置2個DMRS符號；

Defines whether the UE supports DM-RS pattern for DL reception and/or UL transmission with 2 symbols front-loaded DM-RS with one additional 2 symbols DMRS.

 NOTE : front-loaded DMRS mean mappingType B 

Type B的 front-loaded DMRS定：

featureSetsDownlink-v1540 {
    {
      oneFL-DMRS-TwoAdditionalDMRS-DL supported,
      twoFL-DMRS-TwoAdditionalDMRS-DL supported,
      oneFL-DMRS-ThreeAdditionalDMRS-DL supported
    }
}
