Abstract
The present disclosure relates to transmitting and receiving of system information which includes controlling the transmission and/or the reception to transmit and/or receive system information including a coverage enhancement level indication for indicating enhanced coverage levels supported by the wireless communication system and to transmit and/or receive system information including a group of information elements common for different coverage enhancement levels and information elements specific for different coverage enhancement levels grouped for respective coverage enhancement levels.
Claims16
An integrated circuit for controlling a communication apparatus, the integrated circuit comprising:
- receiving circuitry, which, in operation, receives system information for the communication apparatus in Coverage Enhancement (CE), the system information including information elements common to a plurality of CE levels including one or more radio condition threshold values used to determine a CE level out of the plurality of CE levels and at least one information element specific to one or more of the plurality of CE levels;
- control circuitry, which, in operation, performs soft-combining of the received system information in a plurality of redundancy versions cyclically repeated a defined plurality of times;
- and
- decoding circuitry, which, after each of the soft-combining, attempts to decode the system information,
- wherein the receiving circuitry, in operation, receives the information elements common to the plurality of CE levels with a second frequency equal to or lower than a first frequency with which the information elements common to the plurality of CE levels are transmitted, depending on a current CE status of the communication apparatus.
A communication apparatus, comprising:
- a receiver, which, in operation, receives system information for the communication apparatus in Coverage Enhancement (CE), the system information including information elements common to a plurality of CE levels including one or more radio condition threshold values used to determine a CE level out of the plurality of CE levels and at least one information element specific to one or more of the plurality of CE levels;
- control circuitry, which, in operation, performs soft-combining of the received system information in a plurality of redundancy versions cyclically repeated a defined plurality of times;
- and
- a decoder, which, after each of the soft-combining, attempts to decode the system information,
- wherein the receiver, in operation, receives the information elements common to the plurality of CE levels with a second frequency equal to or lower than a first frequency with which the information elements common to the plurality of CE levels are transmitted, depending on a current CE status of the communication apparatus.
