If pagingSearchSpace is set to zero and if SS/PBCH block and CORESET multiplexing pattern is 2 or 3 (as specified in TS 38.213):
  • for ssb-periodicityServingCell of 5 or 10 ms, N can be set to one of {oneT, halfT, quarterT, oneEighthT, oneSixteenthT}
  • for ssb-periodicityServingCell of 20 ms, N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}
  • for ssb-periodicityServingCell of 40 ms, N can be set to one of {quarterT, oneEighthT, oneSixteenthT}
  • for ssb-periodicityServingCell of 80 ms, N can be set to one of {oneEighthT, oneSixteenthT}
  • for ssb-periodicityServingCell of 160 ms, N can be set to oneSixteenthT
If pagingSearchSpace is set to zero and if SS/PBCH block and CORESET multiplexing pattern is 1 (as specified in TS 38.213), N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}
If pagingSearchSpace is not set to zero, N can be configured to one of {oneT, halfT, quarterT, oneEighthT, oneSixteenthT}

PEI-Config field descriptions
payloadSizeDCI-2-7
Payload size of PEI DCI, i.e., DCI format 2_7. The size is no larger than the payload size of paging DCI which has maximum of 41 bits and 43 bits for licensed and unlicensed spectrums, respectively.

po-NumPerPEI
The number of PO(s) associated with one PEI monitoring occasion. It is a factor of the total PO number in a paging cycle, i.e N x Ns, as specified in TS 38.304. The maximum number of PF associated with one PEI monitoring occasion is 2. The number of PO mapping to one PEI should be multiple of Ns when po-NumPerPEI is larger than Ns.
SubgroupConfig field descriptions
subgroupsNumPerPO
Total number of subgroups per Paging Occasion (PO) for UE to read subgroups indication from physical-layer signaling. The field represents the sum of CN-assigned and UEID-based subgroups supported by the network. When PEI-Config is configured, there is always at least one subgroup (UEID-based subgroup or CN-assigned subgroup) configured.
subgroupsNumForUEID
Number of subgroups per Paging Occasion (PO) for UE to read subgroups indication from physical-layer signaling, for UEID-based subgrouping method. When present, the field is set to an integer smaller than or equal to subgroupsNumPerPO. subgroupsNumPerPO equals to subgroupsNumForUEID when the network does not configure CN-assigned subgrouping. When pei-Config is configured, the field is absent when the network only configures CN-assigned subgrouping. Both this field and subgroupsNumPerPO are equal to 1 when the network does not configure subgrouping. When pei-Config is configured, if the field is absent, the UE uses subgrouping according to clause 7.3.0 of TS 38.304.
Conditional Presence Explanation
SharedSpectrum2The field is optional present, Need R, if this cell operates with shared spectrum channel access. Otherwise, it is absent, Need R.

Starting position (in number of bit) of the 14 bit INT value applicable for this serving cell (servingCellId) within the DCI payload (see clause 11.2 of TS 38.213). Must be multiples of 14 (bit).
