Abstract: Disclosed are a resource configuration method and apparatus, and a computer storage medium, being used for enabling, when a remaining minimum system information control resource set and an associated synchronization information block are in a time division multiplexing mode, the configuration of the remaining minimum system information control resource set to be more flexible, being applicable to more application scenarios. The resource configuration method comprises: determining that a remaining minimum system information control resource set (RMSI CORESET) and an associated synchronization information block (SS Block) occupy different symbols for transmission in a time division multiplexing mode; and determining the configuration parameters of the RMSI CORESET and the associated SS Block, the remaining minimum system information control resource sets associated with the SS Blocks in each SS Block burst set having identical configuration parameters.

Abstract: The present application relates to the field of wireless communications, and in particular, to a method and device for random access, for use in resolving the problem in the prior art of conflict between a time domain resource used by a terminal for random access and a time domain resource occupied for transmission of a SS Block and/or RMSI. In embodiments of the present application, a terminal determines a PRACH time domain resource configured by a base station for the terminal; when determining that at least one time slot comprises a first type of OFDM symbols used for transmission of a SS Block and/or RMSI, the terminal performs random access by means of OFDM symbols different from the first type of OFDM symbols in the at least one time slot. In the embodiments of the present application, the terminal performs random access by means of OFDM symbols different from the first type of OFDM symbols in the time slot, so that conflict between the time domain resource used for random access and the time domain resource occupied for transmission of the SS Block and/or RMSI is avoided, and the system performance is further improved.

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.
