A method of channel state information (CSI) reporting is disclosed that includes determining, with a user equipment (UE), whether CSI to be reported includes a matrix based on network (NW) triggering and performing, with the UE, CSI reporting based on the determination. The CSI reporting may be periodic, semi-persistent, or aperiodic CSI reporting. The matrix may be W.sub.1,l, W.sub.f,l, or both. The NW triggering may be explicitly performed using one or more downlink control information (DCI) bits. The NW triggering may be implicitly performed based on a location of DCI detected by the UE. In other aspects, a user equipment is also disclosed.

The present disclosure makes full use of all resources available in the sidelink resource pool.

Provided herein is a method of performing, by a first apparatus, wireless communication. The method may include the steps of receiving configuration related to a downlink (DL) positioning reference signal (PRS) from a location management function (LMF); receiving configuration related to an uplink (UL) PRS from a base station; and performing positioning based on round trip time (RTT), based on the configuration related to the DL PRS and the configuration related to the UL PRS.

Disclosed are a method and device for transmitting/receiving a downlink channel from multiple transmission/reception points in a wireless communication system. A method for a terminal to receive a downlink channel in a wireless communication system according to an embodiment of the present disclosure comprises the steps of: receiving a downlink control channel on the basis of two or more transmission configuration indicator (TCI) states associated with one or more control resource sets (CORESETs); and receiving a downlink data channel on the basis of the two or more TCI states associated with one or more CORESETs, on the basis of TCI information not being included in downlink control information (DCI) received through the downlink control channel, wherein the two or more TCI states may be mapped to the downlink data channel on the basis of a prescribed mapping scheme.

This application relates to a scheduling method, an apparatus, and a system. A first communications apparatus sends first signaling on a first resource, where the first signaling is used to indicate N communications apparatuses. The first communications apparatus sends second signaling on a second resource, where the second signaling is used to schedule the N communications apparatuses to send or receive first data, and the first resource has an association relationship with the second resource. In addition, the first resource has the association relationship with the second resource. In this case, a receive end of the first signaling and the second signaling may determine the second resource after determining the first resource, so that the second signaling is only detected on the second resource, and blind detection does not need to be performed on too many resources.

Various embodiments of the present disclosure provide a method for random access. The method which may be performed by a terminal device comprises determining a interlace configuration for uplink shared channel transmission to a network node in a two-step contention-free random access procedure. The method further comprises performing the uplink shared channel transmission to the network node in the two-step contention-free random access procedure, according to the determined interlace configuration. According to some embodiments of the present disclosure, the interlaced resource allocation for uplink shared channel transmission may be configured for a two-step contention-free random access procedure in a flexible and efficient way, so that the performance of the random access procedure can be improved.

Disclosed are a method and a device for transmitting or receiving a signal on the basis of a space parameter in a wireless communication system. A method for performing downlink reception or uplink transmission by a terminal in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: transmitting information related to a beam switching time of the terminal to a base station; receiving, from the base station, downlink control information (DCI) including information on the downlink reception or the uplink transmission; and on the basis of the beam switching time and a predetermined threshold value, applying one space parameter set among multiple space parameter sets so as to perform the downlink reception or the uplink transmission, wherein at least one of the beam switching time and the predetermined threshold value may be based on at least one of subcarrier spacing, the position of a frequency, a capability of the terminal, and a cyclic prefix (CP)-related configuration.
