The present application claims the benefit of priority under 35 U.S.C. § 120 as a continuation of PCT Patent Application No. PCT/CN2018/116114, filed on Nov. 19, 2018, which claims priority to Chinese Patent Application No. 201711148126.3, filed in the Chinese Patent Office on Nov. 17, 2017, the entire contents of each of which are herein incorporated by reference.
The present application relates to the field of communications, for example, information transmission and reception methods and apparatuses.
In a new generation of a radio communication system (New Radio, NR), system information is divided into minimum system information (minimum SI) and other system information (other SI). The minimum system information is divided into “master system information (Mater Information Block, MIB)” carried on a physical broadcast channel (Physical Broadcast Channel, PBCH), and “remaining minimum system information (remaining minimum SI, RMSI)” carried on a physical downlink shared channel; and the master system information is used to provide basic system parameters of a cell, and the remaining minimum system information is used to provide configuration information related to initial access, such as transmission configuration of an initial access request, and message reception configuration of an initial access response. Other system information that needs to be broadcast is referred to as other system information.
