Method for transmitting and receiving system information via a broadcast channel (BCH) and a downlink shared channel (DL—SCH)

A method for transmitting, by a base station to at least one mobile terminal, system information via a broadcast control channel (BCCH), which is a logical channel between a radio link control (RLC) layer and a medium access control (MAC) layer, and a broadcast channel (BCH) and a downlink shared channel (DL_SCH), the BCH and DL_SCH being transport channels between the MAC layer and a physical layer and which are each directly mapped to the BCCH, the method comprising:

• transmitting a block of first system information to the at least one mobile terminal in a predetermined frame of the BCH, and
• after the block of first system information is transmitted, transmitting a first block of second system information to the at least one mobile terminal in a predetermined frame of the DL_SCH configured to carry system information and user traffic, the first block of second system information including schedule information relating to a second block of second system information,
• wherein the first block of second system information and the second block of second system information are transmitted via the DL_SCH in accordance with a specific control channel, and
• wherein the specific control channel indicates frequency and time information via which the first block of second system information and the second block of second system information are transmitted via the DL_SCH.
