Abstract: A system information configuration method and device are provided, related to the field of communications. The method includes: determining, based on a target parameter which is predetermined, a frequency offset configuration parameter of a Remaining Minimum System Information (RMSI) Control Resource Set (CORESET) with respect to a System Synchronization Block (SSB), where the target parameter includes one or more of a channel bandwidth parameter, a Subcarrier Spacing (SCS) parameter of RMSI, an SCS parameter of SSB, a System Synchronization (SS) Raster parameter, and a RMSI CORESET bandwidth parameter; and performing a frequency offset configuration of the RMSI CORESET with respect to the SSB according to the frequency offset configuration parameter.

Abstract: Disclosed are a method and apparatus for determining an RA-RNTI. In the present application, a base station receives a random access preamble sent by a terminal; the base station determines an RA-RNTI according to a time-frequency resource occupied by the random access preamble, wherein the time-frequency resource is a time-frequency resource of an orthogonal frequency division multiplexing (OFDM) symbol level; and the base station sends a random access response message, wherein the random access response message comprises downlink control information allocated, by the base station, for the terminal, and the downlink control information is scrambled using the RA-RNTI. By means of the present application, an RA-RNTI can be determined during a random access process of an NR system.

Abstract: A timing advance indication method, a base station, a terminal and a device are provided. The method includes: transmitting subcarrier spacing configuration information of a physical uplink shared channel and/or a physical uplink control channel to a terminal; receiving a preamble fed back by the terminal based on subcarrier spacing configuration information; obtaining a quantized value of a timing advance corresponding to a tracking area based on the preamble; and transmitting the quantized value of the timing advance to the terminal.

Abstract: A random access method, a base station and a User Equipment (UE) are provided. A random access method applied to a base station side includes: receiving, by using a pre-configured first SubCarrier Spacing (SCS), a first random access preamble message transmitted by a UE when the base station instructs the UE to perform an initial access according to a contention-based random access mechanism; transmitting, by using a predetermined second SCS or a third SCS configured by a network, a first Random Access Response (RAR) message to the UE; receiving, by using a predetermined fourth SCS or a fifth SCS configured by the network, a first scheduling transmission message transmitted by the UE; and transmitting, by using a predetermined sixth SCS or a seventh SCS configured by the network, a first collision resolution message to the UE, to complete the initial access.
