In a system in which the base station supports a full-duplex radio communication, the base station needs to group user equipments within its service range, configure an identical radio resource pattern for user equipments in a same group and configures different radio resource patterns for user equipments in different groups. In this way, in a process that the base station selects, according to the configured radio resource patterns, multiple user equipments, which are in different communication states on the same radio resource for communication, not all the user equipments will receive the uplink data sent by other user equipment, and only user equipments in different groups may have different communication states on the same radio resource respectively. In this way, an interference between user equipments can be reduced appropriately.
