Transmission and reception of broadcast system information in a mobile communication system

A method for transmitting broadcast system information in a radio access network of a mobile communication system, the method comprising the following steps performed by a transmission apparatus:

• mapping system information blocks of a broadcast control logical channel to a shared transport channel or a broadcast transport channel depending on a property of a respective system information block, and
• transmitting the system information blocks via the shared transport channel and the broadcast transport channel, respectively.

A method for receiving broadcast system information in a radio access network of a mobile communication system, the method comprising the following steps performed by a mobile terminal:

• receiving a master information block of a broadcast control logical channel via a broadcast transport channel, wherein the master information block comprises control information associated to a respective one of a plurality of system information blocks used to convey the broadcast system information, wherein the associated control information indicates whether a respective system information block is mapped to the broadcast transport channel or a shared transport channel, and
• receiving system information blocks of a broadcast control logical channel on a shared transport channel and a broadcast transport channel according to the indication in the master information block.

A transmission apparatus in a radio access network for transmitting broadcast system information in the radio access network of a mobile communication system, the apparatus comprising:

• a processor for mapping system information blocks of a broadcast control logical channel to a shared transport channel and a broadcast transport channel depending on a property of a respective system information block, and
• a transmitter for transmitting the system information blocks via the shared transport channel and the broadcast transport channel, respectively.

A mobile terminal for receiving broadcast system information in a radio access network of a mobile communication system, the mobile terminal comprising:

• a receiver for receiving a master information block of a broadcast control logical channel via a broadcast transport channel,
• a processor for obtaining control information from the master information block, the control information being associated to a respective one of a plurality of system information blocks used to convey the broadcast system information, wherein the associated control information indicates whether a respective system information block is mapped to the broadcast transport channel or a shared transport channel, and
• wherein the receiver is further adapted to receive system information blocks of a broadcast control logical channel on a shared transport channel and a broadcast transport channel according to the indication in the master information block.

A computer-readable medium storing instructions that, when executed by a processor of a transmission apparatus, causes the transmission apparatus to transmit broadcast system information in a radio access network of a mobile communication system, by:

• mapping system information blocks of a broadcast control logical channel to a shared transport channel or a broadcast transport channel depending on a property of a respective system information block, and
• transmitting the system information blocks via the shared transport channel and the broadcast transport channel, respectively.
