请教PDCCH DMRS与SSB功率比问题

somethinga

213协议4.1节里有如下描述“Ifthe UE has not been provided dedicated higher layer parameters, the UE mayassume that the ratio of PDCCH DMRS EPRE to SSS EPRE is within -8 dB and 8 dBwhen the UE monitors PDCCHs for a DCI format 1_0 with CRC scrambled by SI-RNTI,P-RNTI, or RA-RNTI.”，请问这里所述的高层参数[size=13.3333px]dedicated higher layer parameters具体指什么？331里没找到相关参数，谢谢！
