The embodiments of the invention provide an information transmission method and apparatus. The method comprises: determining, from a plurality of numerologies, a target numerology, and transmitting or receiving, according to the target numerology, a synchronization signal.

The present invention relates to a wireless communication system and particularly to a method and a device therefor, the method comprising the steps of: detecting an SSB, the SSB comprising 15 kHz-granularity-based offset information; determining, on the basis of the 15 kHz-granularity-based offset information, a subcarrier offset used to identify the frequency position of a CORESET linked to the SSB; and monitoring, on the basis of the subcarrier offset, the CORESET linked to the SSB.

Provided are a method and an apparatus for performing physical resource block (PRB) indexing in a wireless communication system. A user equipment (UE) receives information on an offset between a synchronization signal (SS) block and a system bandwidth from a network through the SS block and performs the PRB indexing on the system bandwidth on the basis of the information on the offset.

A first exemplary embodiment provides a method performed by a wireless device (10) for handling communication of the wireless device in a wireless communication network, wherein the wireless communication network comprises a first radio network node (12) and a second radio network node (13), which first radio network node (12) serves the wireless device (10). The wireless device receives an indication indicating a mapping between one or more channel state information reference signals, CSI-RS, and one or more random access channel, RACH, configurations. The wireless device receives one or more CSI-RSs from the second radio network node (13), and selects a CSI-RS out of the one or more received CSI-RSs. The wireless device further initiates a random access procedure towards the second radio network node (13) using at least part of the RACH configuration mapped to the selected CSI-RS.

Disclosed in various embodiments are a method for transmitting/receiving a signal in a wireless communication system, and a device supporting same. More particularly, disclosed in various embodiments are a method for transmitting/receiving a synchronization signal block (SSB) in an unlicensed band, and a device supporting same.

Provided are a configuration method and a transmission method of a new reference signal for frequency offset estimation in a novel wireless communication system. The method may include configuring a synchronization signal to be transmitted through a first bandwidth part of one or more bandwidth parts configured by dividing an entire bandwidth into one or more parts, allocating the one or more reference signals for estimating the frequency offset on one or more resources other than a resource for configuring the synchronization signal, and transmitting the one or more reference signals for estimating the frequency offset.

In a method and a device for transmitting and receiving signals in a wireless communication system according to an embodiment of the present invention, N control resource set #0s (CORESET #0s) are received on the basis of first subcarrier spacing (SCS), and N synchronization signal blocks (SSBs) are received on the basis of second SCS. The SSBs are continuously located in the time domain. The CORESET #0s are located in a slot to which a most advanced SSB in the time domain from among the SSBs belongs, and are continuously located from symbol #0 within the slot.

A wireless device transmits a preamble based on a first spatial filter. The wireless device receives an uplink grant indicating transport block (TB) repetitions and a reference signal (RS). The wireless device transmits, based on the first spatial filter, first repetitions of the TB repetitions. The wireless device transmits, based on a second spatial filter associated with the RS, second repetitions of the TB repetitions.

This application provides a communication method and apparatus and a computer-readable storage medium. The method includes: receiving one or more synchronization information blocks SSBs; determining, based on a first SSB and/or a second SSB, a network type corresponding to the one or more SSBs; and determining an access network based on the network type. According to technical solutions provided in this application, a network type of an access network can be accurately identified in a frequency sweep stage.
