The present disclosure discloses a method for receiving a downlink signal by a UE in a wireless communication system. Particularly, the method may include receiving a synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH), and obtaining an indicator indicating a subcarrier spacing for the downlink channel from the PBCH, and receiving the downlink signal on the basis of the subcarrier spacing. The indicator may indicate a different subcarrier spacing according to a frequency band in which the UE operates.

The present disclosure provides a grant free uplink transmission method, the method is performed at a user equipment side, comprising: determining, according to configuration information for grant free uplink transmission received from a base station, a radio network temporary identifier GF-RNTI for grant free uplink transmission, and transmitting an uplink signal; and monitoring feedback from the base station in a downlink control channel by using the determined GF-RNTI.

A method of wireless communication includes receiving, by a UE, one or more configuration messages indicating synchronization signals (SS) and physical broadcast channel (PBCH) block measurement timing configuration (SMTC) parameters. The SMTC parameters indicate SMTC windows associated with reception of synchronization signal blocks (SSBs) by the UE from a base station. The method further includes, based on detecting one or more trigger conditions, transitioning, by the UE, from an inactive state to an active state to receive, during a time interval distinct from the SMTC windows, one or more SSBs from the base station. The method further includes performing, by the UE, one or more beam management operations based on the one or more SSBs received during the time interval.

Aspects of the present disclosure provide techniques for interference coordination between wireless nodes (e.g., nodes of an Integrated Access and Backhaul (IAB) network). The techniques generally include determining, by a first wireless node, resources for sending an indication of interference coordination to a second wireless node, and sending the indication to the second wireless node using the determined resources, as part of an interference coordination procedure.

User equipment may configure a transmitter or receiver to conform to regulations or standards of a geographical region to communicate with non-terrestrial networks (e.g., satellite networks). In one embodiment, the user equipment may receive an indication of a regulation or standard to which to conform to from a terrestrial communication node, and apply an emission mask to the transmitter based on the regulation or standard. The user equipment may additionally or alternatively configure the receiver to be compliant with a noise level tolerance of a received signal specified by the regulation or standard. In some embodiments, the user equipment may implement a frequency offset between the received signal and an interfering signal associated with the noise level tolerance that is scaled based at least on a channel bandwidth associated with the desired signal. Moreover, the user equipment may scale the noise level tolerance based on the frequency offset.

The present invention relates to a method and an apparatus for a base station transmitting a downlink signal for a machine-type communication (MTC) terminal.

The present invention discloses a method for a user equipment to receive system information in a wireless communication system. Particularly, the method is characterized in detecting a first synchronization signal block configured with a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS) and a Physical Broadcasting Channel (PBCH) at a specific frequency position, determining a presence or non-presence of system information corresponding to the first synchronization signal block within a first synchronization raster corresponding to a specific frequency position based on a system information indicator included in the PBCH, and if the system information corresponding to the first synchronization signal block is determined as not existing, determining a second synchronization raster having system information exist therein based on the system information indicator.

Information transmission and reception methods and apparatus are disclosed, where the transmission method includes: carrying configuration information of a control resource set on a physical broadcast channel; where the configuration information is used to indicate to a terminal at least one of the following of the control resource set: time domain position information and frequency domain position information; and transmitting the control resource set to the terminal according to the configuration information.

Implementations of the present disclosure provide an indication method, a detection method, and a related device. In the present disclosure, a network device indicates to user equipment, within what frequency domain ranges there is no SSB transmission, thereby preventing the user equipment from performing useless searches in the frequency domain ranges in which there is no SSB.
