Abstract

The present invention relates to wireless communications and particularly to methods and apparatus for requesting, transmitting and using system information (SI) in wireless communication. The invention aims to overcome efficiency problems observed in prior art SIB transmission methods. Thus, the present invention provides a base station apparatus comprising: transmitting circuitry configured to transmit, to a user equipment (UE), minimum system information (SI), the minimum SI being required for initial access, the minimum SI comprising: plural indications, each of the plural indications indicating whether or not a corresponding system information block (SIB) of other SI is provided on-demand, the other SI comprising information not provided by the minimum SI, and scheduling information indicating a transmission schedule(s) of one or more SIBs of the other SI, and; receiving circuitry configured to receive a request for transmission of a corresponding SIB of the other SI, in a case where one of the plural indications indicates that the corresponding SIB of the other SI is provided on-demand.

Claims (11)

WHAT IS CLAIMED IS:
