Abstract

A method including receiving, by a user equipment (UE), a block of first system information from a base station via the BCH, and receiving, by the UE, a first block of second system information from the base station via the DL_SCH. The first block of second system information is scheduled with a fixed time offset. The method further includes receiving, by the UE, a plurality of second blocks of second system information from the base station via the DL_SCH in accordance with scheduling information included in the first block of second system information. The first block of second system information includes the scheduling information, value tag information, and cell access related information. The cell access related information includes at least one of Public Land Mobile Network (PLMN) identity information, tracking area information, and cell barred information. A specific control channel indicates frequency and time information.
