RateMatchPattern

RB-symbol级的速率匹配，由RateMatchPattern和RateMatchPatternGroup共同作用。 

每个小区最多配置4个小区级的RateMatchPattern和每个bwp最多配置4个bwp级的RateMatchPattern。 

RateMatchPattern的配置如下，可以为时频域bitmap和周期偏移（bwp级或小区级），也可以为coreset配置（周期偏移为coreset关联的searchSpace的配置）

RateMatchPattern ::=                SEQUENCE {

    rateMatchPatternId                  RateMatchPatternId, 

    patternType                         CHOICE {

        bitmaps                             SEQUENCE {

            resourceBlocks                      BIT STRING (SIZE (275)),

            symbolsInResourceBlock              CHOICE {

                oneSlot                             BIT STRING (SIZE (14)),

                twoSlots                            BIT STRING (SIZE (28))

            },

            periodicityAndPattern               CHOICE {

                n2                                  BIT STRING (SIZE (2)),

                n4                                  BIT STRING (SIZE (4)),

                n5                                  BIT STRING (SIZE (5)),

                n8                                  BIT STRING (SIZE (8)),

                n10                                 BIT STRING (SIZE (10)),

                n20                                 BIT STRING (SIZE (20)),

                n40                                 BIT STRING (SIZE (40))

            }                                                                                           OPTIONAL,   -- Need S

}

 未包含在rateMatchPatternGroup1 和rateMatchPatternGroup2的rateMatchPattern属于静态的速率匹配模式，即其中包含的为不可用于PDSCH的RE。对应rateMatchingResrcSetSemi-Static

 包含在rateMatchPatternGroup1 和rateMatchPatternGroup2中的rateMatchPattern属于动态配置的速率匹配模式，其中的RE是否可用于PDSCH，由DCI动态指示。对应rateMatchingResrcSetDynamic

 而coreset是否能加入rateMatchPatternGroup，由DCI动态指示是否rateMatchPattern配置中的coreset的RE是否能用于PDSCH，为一个UE能力，rateMatchingCtrlResrcSetDynamic
