1. A control information communication method using downlink control information (DCI) format 6-2 for paging and for multicast, the method comprising:
formatting a DCI using the DCI format 6-2;
scrambling the DCI by a paging radio network temporary identifier (P-RNTI) based on the DCI being used for paging; and
scrambling the DCI by a single cell radio network temporary identifier (SC-RNTI) based on the DCI being used for multicast,
wherein the DCI used for multicast comprises indication information and scheduling information,
wherein the indication information is used to indicate whether a multicast control channel is updated,
wherein the scheduling information is used to schedule a multicast control channel,
wherein the scheduling information comprises information about (1) resource block allocation of the multicast control channel, (2) a modulation and coding scheme of the multicast control channel, (3) a quantity of repetitions of the multicast control channel, and (4) a quantity of repetitions of the DCI,
wherein the information about the resource block allocation of the multicast control channel occupies

bit positions in the DCI format 6-2,
wherein the information about the modulation and coding scheme of the multicast control channel occupies three bit positions in the DCI format 6-2,
wherein the information about the quantity of repetitions of the multicast control channel occupies three bit positions in the DCI format 6-2,
wherein the information about the quantity of repetitions of the DCI occupies two bit positions in the DCI format 6-2,
wherein NRBDL refers to a quantity of resource blocks included in a downlink bandwidth,
wherein the resource block allocation in the DCI indicates a narrowband of a single-cell multicast control channel (SC-MCCH) transmission, and
wherein a narrowband of a single-cell multicast traffic channel (SC-MTCH) transmission is determined based on the narrowband of the SC-MCCH transmission; and
sending the DCI to user equipment.
