Abstract

The invention provides an information sending method, a receiving method, a network device and a terminal, and relates to the technical field of communication. The information sending method is applied to a network device, and includes: sending a first synchronization signal block to a terminal at a first frequency point; wherein, the master information block MIB of the first synchronization signal block is not used to indicate the time and frequency of the control resource group Resource and physical downlink control channel PDCCH monitoring information, wherein the MIB of the first synchronization signal block carries auxiliary information of the second frequency point. The above solution, by carrying auxiliary information of the second frequency point in the first synchronization signal block, instructs the terminal how to perform subsequent actions when receiving the synchronization signal block, so as to reduce the power consumption, cell search and access delay of the terminal .

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information sending method, a receiving method, network equipment and a terminal. Background technique [0002] In the design of a New Radio (NR) system, an NR base station needs to send a Synchronization Signal Block (SSB) for a terminal to perform synchronization, obtain system information, measure and evaluate, and so on. One SSB consists of two parts: New radio Synchronization Signal (NR-SS) and New radio Physical Broadcast Channel (New radio Physical Broadcast Channel, NR-PBCH). NR-SS is divided into two parts: the New radio Primary Synchronization Signal (NR-PSS) and the New radio Secondary Synchronization Signal (NR-SSS), and the generation of the NR-SS sequence and the physical Cell identification (Physical Cell Identifier, PCI) related. After detecting the SSB, the terminal can obtain the PCI of the cell to which the currently detected SSB belongs by ...
