SI-RequestConfigRepetition (SI-RequestConfigRepetition-r18)
SI-RequestConfigRepetition-r18 is an RRC information element of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.
Definition
The IE SI-RequestConfigRepetition contains configuration for Msg1 based SI request with Msg1 repetition. For the random access parameters (e.g. prach-RootSequenceIndex , msg1-SubcarrierSpacing and msg1-RepetitionTimeOffsetROGroup , etc.) not configured in SI-RequestConfigRepetition , the UE applies the parameters configured in rach-ConfigCommon corresponding to the RACH resource set selected upon RACH initialization (as specified in TS 38.321 [3]), of the initial uplink BWP unless otherwise specified.
