But generally, the system information is sent by the network equipment to the user equipment together, that is, the configuration information of the new function added is also sent in the same system information, so the traditional UE (for example, supports 5G-NR R15 version but does not support IAB) also needs to receive and decode all system messages, which may have a bad impact on delay and power

Abstract

The invention provides a method for receiving system information. The method comprises the following steps: obtaining a control resource set and a search space for searching downlink control information; determining a search space for detecting the PDCCH according to the control resource set and the search space, and detecting and decoding a physical downlink control channel (PDCCH) in the determined search space to obtain downlink scheduling information for a physical downlink shared channel (PDSCH); and detecting and decoding a physical downlink shared channel to obtain system information, the system information including a first system information block (SIB) 1 and a second system information block 1 respectively carried on separate physical downlink shared channels.

Description

technical field [0001] The present disclosure relates to the field of wireless communication, and more particularly, to a method and apparatus for receiving system information. Background technique [0002] The transmission in the wireless communication system includes: the transmission from the base station (gNB) to the user equipment (UE, User Equipment) (called downlink transmission), the corresponding time slot is called the downlink time slot, the transmission from the UE to the base station (called the downlink transmission) Uplink transmission), the corresponding time slot is called the uplink time slot. [0003] In the downlink communication of the wireless communication system, the system periodically sends the synchronization signal and the broadcast channel to the user through the synchronization signal block (SSB, synchronization signal / PBCH block), which is the synchronization signal block period (SSB periodicity, SSB period), Or called the synchronization sign...
