In some aspects, a user equipment (UE) may receive a paging early indication (PEI) indicating whether at least one UE in a UE group or a UE sub-group including the UE is to be paged in a paging occasion. In some aspects, a sequence on which the PEI is based is a physical downlink control channel (PDCCH)-based sequence. In some aspects, the PEI is a sequence-based PEI and is received based at least in part on a sequence configuration configured on the UE. In some aspects, the PEI is a sequence-based PEI and is received based at least in part on a distributed resource block allocation associated with the sequence. The UE may selectively process a paging PDCCH associated with the paging occasion based at least in part on the PEI. Numerous other aspects are described. ## Claims ### Claim 1 A user equipment (UE) for wireless communication, comprising: one or more memories; and one or more processors coupled to the one or more memories, the one or more memories comprising instructions executable by the one or more processors individually or collectively to cause the UE to: receive a paging early indication (PEI), the PEI indicating whether at least one UE in a UE group or a UE sub-group including the UE is to be paged in a paging occasion, wherein a sequence on which the PEI is based is a physical downlink control channel (PDCCH)-based sequence, and wherein the PEI is received in a PDCCH candidate of a plurality of PDCCH candidates, wherein each PDCCH candidate of the plurality of PDCCH candidates is associated with a corresponding set of UEs of a plurality of sets of UEs;
