15.4.2.10 Common signal/channel transmissions adaptation

For adaptation of paging in time domain, the value range for parameter N, which is the number of paging frames in one paging cycle, is extended to make it possible to have increased interval between PFs. The value range for Ns, which is the number of paging occasions within one paging frame, is increased to compensate the decrease in the number of PFs. UEs supporting paging adaptation and PEI can monitor PEI according to the additional PEI configuration. UEs supporting paging adaptation and LP-WUS can monitor LP-WUS according to the LP-WUS occasion offset configuration for paging adaptation.

Adaptation of SSB in time domain is supported for SCells for UEs in RRC_CONNECTED configured with carrier aggregation (CA). SSB adaptation is indicated via DCI. Multiple SMTC configurations can be configured to the UE, and the UE selects one SMTC based on the SSB adaptation indication. SSB adaptation is not applicable to deactivated SCells.

Adaptation of PRACH configurations in time domain is supported for 4-step RACH CBRA. Furthermore, additional PRACH resource 1-bit indication in PDCCH-order applies to both CFRA and CBRA in the serving cell. Additional RACH resources are configured together with the common RACH resources in the same set of RACH resources, and the network can indicate via DCI whether the additional RACH resources are available as specified in section 8.1 of TS 38.213 [38].
